BACKGROUND OF THE INVENTION

Field of Invention

The present invention relates to a human-machine interface system and, in particular, to a visual interface system.

Related Art

Recently, touch panels have been widely applied to the commercial electronic products such as mobile phones, digital cameras, MP3, PDA, GPS, tablet PC, UMPC, and the likes. In these electronic products, the touch panel is bound with a screen to form a touch input display apparatus. A manufacturing method of a conventional touch input display apparatus is to dispose a touch panel on a display panel of a display module. However, due to the additional touch panel, this approach not only increases the weight and sized of the product, but also the cost.

In order to broaden the applications of the commercial electronic products, some products have been added with the new function of near field communication (NFC), which can be used to replace the conventional IC card (e.g. door card, credit card, ticket, and etc.), exchange information (e.g. music, image, name card, and etc.) between two electronic devices, or the likes. Accordingly, it is desired to create a product with a simple structure and more functions.

Therefore, it is an important subject to provide a visual interface system which can achieve the desired touch input function without configuring an additional touch panel, thereby making the product lighter and thinner, lowering the production cost, and providing the NFC function for broadening the application field.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a visual interface system that can achieve the touch input function without configuring an additional touch panel, and is equipped with a near field communication (NFC) function.

The present invention can be implemented by the following technical proposals.

A visual interface system of the invention includes an operation apparatus and a matrix display apparatus. The matrix display apparatus includes a display surface and a matrix substrate including a substrate and a matrix. The matrix is disposed at one side of the substrate while the display surface is located at the other side of the substrate. When the operation apparatus is operated on the display surface, an encoded signal is coupled to the operation apparatus from the matrix substrate, and the operation apparatus receives the encoded signal so as to generate a transmission signal.

In one embodiment, the encoded signal is capacitive coupled to the operation apparatus from the matrix substrate.

In one embodiment, the transmission signal is transmitted to the matrix display apparatus or other apparatuses outside the visual interface system. The transmission signal includes touch input information, instruction information, identification information, transaction information, file information or other information. Another apparatus outside the system or the matrix display apparatus processes the transmission signal to obtain an information signal, which may includes touch input information, instruction information, identification information, transaction information, file information or other information.

In one embodiment, the visual interface system further includes at least one relay apparatus for processing the transmission signal to generate a relay process signal. The relay process signal is transmitted to the matrix display apparatus or other apparatuses outside the visual interface system. The transmission signal may include touch input information, instruction information, identification information, transaction information, file information or other information. Besides, the relay process signal may also include touch input information, instruction information, identification information, transaction information, file information or other information. Another apparatus outside the system or the matrix display apparatus processes the relay process signal to obtain an information signal, which may includes touch input information, instruction information, identification information, transaction information, file information or other information.

In one embodiment, the visual interface system further includes a mode trigger apparatus for enabling the matrix display apparatus into an operating mode to output the encoded signal as the mode trigger apparatus is triggered by a user or the operation apparatus.

In one embodiment, when the operation apparatus is a user, the visual interface system further includes a sensing apparatus, and then when the user touches the display surface and the sensing apparatus simultaneously, the transmission signal is transmitted to the sensing apparatus. The sensing apparatus is electrically coupled with other apparatuses outside the visual interface system or the matrix display apparatus.

In one embodiment, the matrix further includes a plurality of row electrodes and a plurality of column electrodes. The row electrodes and the column electrodes are intersected, and the encoded signal is applied to the row electrodes or the column electrodes.

In one embodiment, the matrix further includes a plurality of transistors and a plurality of pixel electrodes, and the transistors are electrically connected with the row electrodes, the column electrodes and the pixel electrodes.

In the visual interface system of the invention, when the operation apparatus is operated on the display surface, the encoded signal is coupled to the operation apparatus from the matrix substrate, and the operation apparatus receives the encoded signal to generate a transmission signal. The transmission signal can be transmitted to other apparatuses outside the system or at least one relay apparatus, or be sent back to the matrix display apparatus. During this transmission procedure, the transmission signal can be processed by other apparatuses outside the system, and/or at least one relay apparatus, and/or the matrix display apparatus, so as to retrieve the information (e.g. touch input information, instruction information, identification information, transaction information, file information or other information) contained in the encoded signal/signal processed by the relay apparatus/transmission signal.

As mentioned above, the visual interface system of the invention can be directly applied to the system containing matrix structure such as TFT LCD panel, OLED panel, LED panel, electrophoretic display panel, MEMS display panel, or the likes, thereby integrating display, touch input and data transmission functions together. Thus, the manufactured products can be lighter and thinner and the product cost can be decreased, thereby improving the product competitiveness. Moreover, the encoded signal is coupled to the external operation apparatus instead of being directly read by the matrix substrate, so that it is unnecessary to modify the layout on the matrix substrate. For example, regarding the touch input application, it is unnecessary to add the capacitance sensing components in the display panel for detecting the change of external capacitance values. As a result, the present invention can decrease the manufacturing cost and shrink the process time.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

FIG. 1 is a block diagram of a visual interface system 1 according to a first embodiment of the invention. The visual interface system 1 includes an operation apparatus 11 and a matrix display apparatus 12, which are coupled with each other. For example, the operation apparatus 11 is capacitive coupled to the matrix display apparatus 12 for transmitting signals, which is a non-contact signal transmission.

In this embodiment, the operation apparatus 11 is, for example, a stylus, an IC card, an NFC reading apparatus, or a user (especially the hand of a user). When the operation apparatus 11 is an electronic apparatus, it may include some functional circuits such as a process control circuit, a storage circuit or a transmission circuit. Herein, any circuit can be composed of hardware, software or firmware, or their combinations. When the operation apparatus 11 is a user, the user (operation apparatus) can serve as a conductor for transmitting signals.

FIG. 2 is a side view of the matrix display apparatus 12. As shown in FIG. 2, the matrix display apparatus 12 includes a display surface 121 and a matrix substrate 122. The matrix substrate 122 includes a substrate 123 and a matrix 124. The matrix 124 is disposed at one side of the substrate 123, while the display surface 121 is located at the other side of the substrate 123. In this embodiment, the display surface 121 is the surface of the matrix display apparatus 12, which is closest to the viewer when the viewer is watching the images displayed on the matrix display apparatus 12. Besides, the matrix display apparatus 12 may further include a protect glass 125 disposed on one side of the substrate 123 opposite to the matrix 124. In this case, the display surface 121 is the surface of the protect glass closest to the viewer. Moreover, one side of the substrate 123 close to the protect glass 125 may be further configured with other components such as a polarizer, frame, or the likes.

In this embodiment, the matrix substrate 122 is a substrate configured with pixel matrix for displaying images, such as the TFT substrate of LCD panel, OLED panel, LED panel, electrophoretic panel, MEMS display panel, and the likes. The matrix 124 includes a plurality of row electrodes, a plurality of column electrodes, and a plurality of pixel electrodes, wherein the row electrodes and the column electrodes are intersected. Moreover, the matrix 124 can be an active matrix or a passive matrix. In this embodiment, the matrix 124 is an active matrix for example. Besides, the matrix 124 may further include a plurality of transistors electrically connected with the row electrodes, the column electrodes and the pixel electrodes, respectively.

The implementation of the embodiment used in the touch input purpose will be described hereinafter. Referring to FIGS. 1 and 2, when the operation apparatus 11 is operated on the display surface 121, an encoded signal ES is coupled to the operation apparatus 11 from the matrix substrate 122, and the operation apparatus 11 receives the encoded signal ES so as to generate a transmission signal TS. Herein, the encoded signal ES contains the coordinates of the display screen of the matrix display apparatus 12, and the transmission signal TS contains the coordinate information. When the encoded signal ES is transmitted form the matrix substrate 122 to the operation apparatus 11, they are wirelessly coupled so as to form a near field signal transmission. Of course, in other applications, the encoded signal can be composed of any information to be transmitted such as touch input information, instruction information, identification information, transaction information, or file information (e.g. music, images, texts, and etc.), so that the transmission signal TS contains the corresponding information.

The encoded signal ES is applied to the matrix substrate 122, and additional display data signal is applied to the matrix substrate 122 for displaying images. The encoded signal ES is applied during the blanking time of the display data signals. For example, the encoded signal ES can be applied between two frames or scan operations of two row electrodes, or during the gap generated as shortening the input time of the display signals. Or, the encoded signal ES can have a higher frequency and be directly added to the display signal.

The encoded signal ES and the transmission signal TS will be further described hereinbelow, wherein the matrix substrate 122 is a TFT substrate of an LCD apparatus.

FIG. 3 is a schematic diagram showing a TFT substrate used in this embodiment. Referring to FIGS. 2 and 3, the matrix 124 includes a plurality of row electrodes S₁˜S_M, a plurality of column electrodes D₁˜D_N, and a plurality of pixel electrodes E₁₁˜E_MN. The row electrodes and the column electrodes are intersected and they are substantially perpendicular to each other or have an included angle. Moreover, the matrix 124 further includes a plurality of transistors for electrically connected with the row electrodes S₁˜S_M, column electrodes D₁˜D_N, and pixel electrodes E₁₁˜E_MN. The row electrodes S₁˜S_M are referred to scan lines, while the column electrodes D₁˜D_N are referred to data lines. Besides, the substrate 123 may further be configured with a driving module, which includes data driving circuit, scan driving circuit, timing control circuit (not shown), and gamma calibration circuit (not shown), for driving the LCD panel to display images. Since the function of the driving module is well known in this art, the detailed description thereof will be omitted here. To be noted, the above-mentioned matrix substrate is for illustrations only and is not to limit the invention. The point of this embodiment is that the encoded signal is transmitted from the matrix substrate to the operation apparatus through the row electrodes S_1˜SM and/or the column electrodes D₁˜D_N so as to generate the transmission signal. The encoded signal may contain various information for different applications such as the reference coordinates of the display screen, the file information of different formats (e.g. personal data, music, images, and etc.), and the likes.

In this embodiment, the column electrodes D₁˜D_N can transmit not only the data signals for displaying images but also the encoded signal. For example, the display signal can be directly added to the encoded signal with higher frequency or be added to the blank period of the displayed data signal such as the period after the scan procedure of all row electrodes S₁˜S_M are finished and before the next scan procedure start (the blank period between frames). Or, the display signal can be inserted after one row electrode is scanned and before the scan of next row electrode, or within the scan period of row electrode by reducing the display data signal period and before sending the display data. Herein, the encoded signal can be provided by expending T-con circuit function and data or scan driving circuit, thereby simplifying the circuit design.

FIG. 4 is a schematic diagram showing the signals for two adjacent row electrodes and two adjacent column electrodes. The row electrodes S₁˜S_M transmit the scan signals SS, respectively, for sequentially turning on the transistors of each column. During the period that the transistors of each column are turned on, each of the column electrodes D₁˜D_N respectively transmits the corresponding encoded signal ES and the displayed data signal DS. The encoded signal ES will be described hereinafter by taking one dimension touch input perpendicular to the row electrode and sequentially encoded in time as an example. Of course, this method can also be applied to another dimension touch input perpendicular to the column electrode. Consequently, a complete two-dimensional touch input can be built. In this embodiment, as shown in FIG. 4, only one column electrode transmits the encoded signal ES when one row electrode transmits the scan signal. In this figure, the encoded signal ES is labeled with a level different from that of the displayed data signal DS; or, in practice, the encoded signal ES and the displayed data signal DS may have the same level.

FIG. 5 is a timing chart of the encoded signal transmitted through each column electrode, wherein the data signals for display are omitted. When the row electrodes transmit the scan signals, the column electrodes D₁˜D_N transmit the encoded signals ES1˜ESN, respectively. To be noted, the encoded signals can be transmitted through different column electrodes, respectively, or multiple column electrodes may transmit the same encoded signal. For example, the column electrodes D₁˜D₃ transmit the encoded signal ES1. This approach may also be applied to the transmission of encoded signals through the row electrodes. Alternatively, the encoded signals transmitted through the row electrodes and the column electrodes may be independent. Since the column electrodes transmit the encoded signals ES, respectively, it is necessary to provide a time reference point for determining the positions of the column electrodes by comparing with the reference point. This reference point can be a specific code and transmitted by the same manner. For example, all column electrodes may output the code “1” twice and then transmit the sequential signal. As mentioned above, if the encoded signal coupled to the operation apparatus is “110010000”, it represents that the operation apparatus is located on the third column electrode, thereby figuring out the coordinate (x-coordinate) of the operation apparatus. Similarly, the y-coordinate of the operation apparatus can be estimated according to another encoded signal applied to the row electrode. Since the scan signals from the row electrodes for driving the display signal are sequentially generated, they can also be used as the encoded signals of the row electrodes. The encoded signals of the row electrodes and the column electrodes may have a common reference point such as the horizontal or vertical sync signals for displaying images. Of course, the column electrodes D₁˜D_N and the row electrodes S₁˜S_M may have more complicated encoded signals, which will not be described in detail here.

The duty cycle of the encoded signal of this embodiment is smaller than that of the data signals so as to maintain the display quality.

When a user grabs the operation apparatus 11 and operates it on the display surface 121 of the matrix display apparatus 12 (e.g. to contact or approach the display surface), the encoded signal is capacitive coupled from the matrix substrate 122 to the operation apparatus 11. This embodiment takes the column electrodes D₁˜D_N for transmitting the encoded signals ES for an example, so the column electrode can serve as one of the capacitive coupling electrodes, and the operation apparatus 11 has the other capacitive coupling electrode. For example, when the operation apparatus 11 is a stylus, a conductor configured at the tip of the stylus functions as the other capacitive coupling electrode.

After receiving the encoded signal ES through the capacitive coupling, the operation apparatus 11 processes the received encoded signal ES to generate a transmission signal TS. This process includes amplifying and/or decoding the encoded signal ES so as to determine the touch position, the touch gesture (writing style), the corresponding function instruction, or which column electrode is touched or pressed. To be noted, the encoded signal ES is capacitive coupled to the operation apparatus 11, and the value of the capacitance relies upon the distance between the operation apparatus and the display surface, which means the amplitude of the signal can provide the z-axis information, so that the operation apparatus 11 can get not only the two-dimensional coordinates but also the z coordinate. Accordingly, the transmission signal TS stands for the result of processing the encoded signal ES, ranging from simple amplification to extract the information like commands of action.

After generating the transmission signal TS, the operation apparatus 11 can transmit the transmission signal TS to the matrix display apparatus 12, other relay apparatus, or other apparatuses outside the visual interface system through wire/wireless electrical coupling (including capacitive coupling) or optical coupling. In this embodiment, the transmission signal TS is directly transmitted to the matrix display apparatus 12.

When this invention is applied to other non-touch input applications, the information to be transmitted is encoded to generate an encoded signal ES based on a specific coding rule, and then the encoded signal ES is capacitive coupled from the matrix substrate 122 (e.g. configured as a cell phone or tablet computer) to the operation apparatus 11 (e.g. short distance wireless reading apparatus attached on the wall). Similarly, the operation apparatus 11 can process (decodes or modifies) the encoded signal ES based on the preset coding rule so as to obtain the transmission signal TS, and then uses the transmission signal TS on the corresponding application such as access control, payment, financial transaction, file transmission, and the likes.

In the above, the operation apparatus 11 processes the encoded signal ES to obtain the information contained in the transmission signal TS such as the touch input information, instruction information, identification information, transaction information, file information or other information. In other embodiments, the matrix display apparatus 12 may process the transmission signal TS to obtain an information signal, which contains the touch input information, instruction information, identification information, transaction information, file information or other information. In this case, the information signal, instead of the transmission signal TS, carries the complete information.

As mentioned above, referring to FIG. 1, in the procedures of coupling the encoded signal ES to the operation apparatus 11 to generate the transmission signal TS and transmitting the transmission signal TS to the matrix display apparatus 12 to obtain the information signal, the signal is processed by, for example, amplification and decoding, which can be handled by either one of the operation apparatus 11 and the matrix display apparatus 12 or among these units. Accordingly, the resulting transmission signal TS or the information signal can contain the touch input information, instruction information, identification information, transaction information, file information or other information.

Besides, a response signal RS can also be transmitted between the operation apparatus 11 and the matrix display apparatus 12. Herein, the response signal RS is for providing the information of the receiving status of the operation apparatus 11 to the matrix display apparatus 12, announcing the operation apparatus 11 to get ready for receiving the signal, or synchronizing the operation apparatus 11 and the matrix display apparatus 12. This configuration can create an interactive mechanism between the transmitting and receiving signals. Moreover, the response signal RS can provide the synchronization function for establishing an information handshaking procedure between the operation apparatus 11 and the matrix display apparatus 12.

FIG. 6 is a schematic drawing of the matrix display apparatus 12 of the visual interface system according to the first embodiment of the invention. Referring to FIG. 6, the visual interface system further includes a mode trigger apparatus 127. When a user or the operation apparatus triggers the mode trigger apparatus 127, the mode trigger apparatus 127 can enable the matrix display apparatus 12 into an operating mode to output the encoded signal ES. For example, when the user needs the touch input function, he/she activates the mode trigger apparatus 127 so as to enable the matrix display apparatus 12 into the touch input mode. Then, the row electrode or column electrode starts to transmit the encoded signal. Otherwise, the matrix display apparatus 12 does not enter the touch input mode and the touch input function of the matrix display apparatus 12 may be partially or totally shut down. This function can save power and prevent the abnormal operation caused by unintentionally contacting the screen. To be noted, the operation of the mode trigger apparatus 127 may have different operation modes. For example, after being activated, the mode trigger apparatus 127 may remain in the new state for a while and then return to the original state, or it may change the state while been activated each time, or it remains in the new state only when the activation lasts. The mode trigger apparatus 127 can be configured on the operation apparatus (e.g. a switch on the stylus) as well. In this case, when the mode trigger apparatus 127 is activated, the operation apparatus 11 transmits a trigger signal to the matrix display apparatus 12 to control it to enter the touch input mode. To be noted, it is possible to switch to touch input function when the mode trigger apparatus 127 is activated once by the user or requests the user to keep activating the mode trigger apparatus 127 to maintain in touch input function. Taking the access card, ticket, credit card or file transmission as examples, the user can trigger the mode trigger apparatus to transmit the encoded signal for authorization or personal identification to the corresponding data receiving device. The mode trigger apparatus 127 can be, for example, a mechanical switch, a touch sensing switch, or the likes.

FIG. 7 is a schematic diagram showing the matrix display apparatus 12 and a user, as the operation apparatus 11, of the visual interface system 1 according to the first embodiment of the invention. In this aspect, the visual interface system 1 further includes a sensing apparatus 128, which is electrically coupled with the matrix display apparatus 12. When the user touches or approaches the display surface 121 and the sensing apparatus 128 of the matrix display apparatus 12 simultaneously, the transmission signal TS is transmitted to the matrix display apparatus 12. The user serves as a large conductor for transmitting the transmission signal TS to the matrix display apparatus 12. In practice, the user can use his/her right hand to operate on the display surface 121, while use the left hand to press the sensing apparatus 128. Accordingly, the encoded signal ES can enter the user body through the right hand, and the transmission signal TS can be outputted from the left hand. The sensing apparatus 128 may also contain the function of the mode trigger apparatus 127. For example, only when the sensing apparatus 128 is pressed by hand, the operation mode will be enabled. This specific function can sufficiently reduce the power consumption and problem of unintentional touch.

FIG. 8 is a block diagram of a visual interface system 1a according to a second embodiment of the invention. The visual interface system 1a includes an operation apparatus 11 and a matrix display apparatus 12. Different from the first embodiment, the visual interface system 1a further includes at least one relay apparatus 13, and the transmission signal TS is transmitted to the matrix display apparatus 12 or other apparatuses outside the visual interface system through the relay apparatus 13. Transmitting the transmission signal TS through user's hand to a relay apparatus 13 will be used to describe the implementation of this embodiment. From the transmission signal TS, the relay apparatus 13 generates a relay processed signal IS and transmits back to the matrix display apparatus 12. The relay apparatus 13 is only for illustration and it is possible to configure multiple relay apparatuses. When the operation apparatus 11 is a user, the user can transmit the transmission signal TS to the relay apparatus 13 instead of transmitting back to the matrix display apparatus 12. Herein, the relay apparatus 13 can be a portable communication device such as a cell phone. Accordingly, the user can be the transmission media for conducting the encoded signal ES outputted from the matrix display apparatus 12 to the relay apparatus 13 for the purpose of transmitting file information.

The relay apparatus 13 can process the transmission signal TS to generate a relay processed signal IS and then transmit the relay processed signal IS to the matrix display apparatus 12. In the procedures of coupling the encoded signal ES to the operation apparatus 11 to generate the transmission signal TS, processing the transmission signal TS by the relay apparatus 13 to generate the relay processed signal IS, and transmitting the relay processed signal IS to the matrix display apparatus 12 to obtain the information signal, the signal is processed by means, for example, amplification, decoding, modifying and/or interpretation, which can be implemented by all or either one of the operation apparatus 11, the matrix display apparatus 12 and the relay apparatus 13. Accordingly, the transmission signal TS, the relay processed signal IS or the information signal can contain the touch input information, instruction information, identification information, transaction information, file information or other information.

Besides, the response signal RS of the first embodiment can also be applied to the operation apparatus, relay apparatus and/or matrix display apparatus of the second embodiment, thereby creating an interactive mechanism between the transmitting and receiving signals. Moreover, the response signal RS can provide the synchronization function for establishing an information handshaking procedure between the operation apparatus, relay apparatus and matrix display apparatus.

In the visual interface system of the invention, when the operation apparatus is operated on the display surface, the encoded signal is coupled to the operation apparatus from the matrix substrate, and the operation apparatus receives the encoded signal to generate a transmission signal. In touch input application, the transmission signal can be directly or indirectly transmitted to the matrix display apparatus. During this transmission procedure, the transmission signal can be processed by operation apparatus, at least one relay apparatus, and/or the matrix display apparatus, so that the matrix display apparatus can retrieve the information contained in the encoded signal and transmission signal, such as touch input information, instruction information, identification information, transaction information, file information or other information.

As mentioned above, the visual interface system of the invention can be directly applied to the system containing matrix structure such as TFT LCD panel, OLED panel, LED panel, electrophoretic display panel, MEMS display panel, or the likes, thereby integrating display, touch input and data transmission functions together. Thus, the products can be lighter and thinner and the product cost can be decreased, thereby improving the product competitiveness. Moreover, the encoded signal is coupled to the external operation apparatus instead of being directly read by the matrix substrate, so that it is unnecessary to modify the layout on the matrix substrate. For example, regarding to the touch input application, it is unnecessary to add the capacitance sensing component in the display panel for detecting the change of external capacitance values. As a result, the present invention can decrease the manufacturing cost and time.

Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
