  • Patent number: 9349339
    Abstract: A source driver pre-charging apparatus including a data detection module, a determining module, and a pre-charging module is disclosed. The data detection module captures a first most significant bit having N bits in a current data and a second most significant bit having N bits in a former data and compares them to generate a compared result. N is a positive integer larger than or equal to 2. The determining module judges whether any data is transited from a first grey-level region to a second grey-level region between the former data and the current data and at least one other grey-level region is existed between the first grey-level region and the second grey-level region. If the judgment result of the determining module is yes, the pre-charging module performs a pre-charging action on an output voltage of a source driver.

  • Patent number: 9341844
    Abstract: A method for validating a control operation to be performed by a target device through a virtual control interface. The virtual control interface is displayed by a head mounted device. A selection instruction of a first area is detected, delivering a first area. A position of gaze is detected, delivering a second area within the virtual control interface. It is detected if the first area and the second area are at least partially overlapping a same dedicated area associated to a control operation to be performed by the target device. In case of detection of an occurrence of the first area and the second area at least partially overlapping, the control operation is validated.

  • Patent number: 9335874
    Abstract: A system and method are provided for validating a signature on a touchscreen using a smart stylus. Software residing on a touchscreen device disables touch input from sources other than the stylus. In one embodiment, the stylus wirelessly transmits a stylus identifier to the touchscreen device to identify the stylus to the device. The stylus may also have a stylus tip that produces an encoded voltage pulse sequence that is used to identify the stylus to the device. A stylus ID is associated with an encoded voltage pulse. The touchscreen device can look up the stylus ID in a database, determine the encoded voltage pulse associated with the stylus ID, and determine that a voltage pulse transmitted by the stylus tip is the pulse associated with the stylus ID, thus validating the source of data input on the touchscreen.

  • Patent number: 9099027
    Abstract: A display panel driving device has a signal line driver. The signal line driver applies a pixel driving voltage based on an input image signal to each signal line of a display panel at a timing corresponding to a clock signal. The signal line driver is divided into a plurality of driver chips connected in cascade by the clock line. The display panel driving device supplies a clock signal through the driver chips. The duty ratio of the clock signal is stabilized when the clock signal passes through the driver chips, without leading to an increase in power consumption and in manufacturing costs.

  • Patent number: 9092094
    Abstract: An optically transmissive element of a computing device can be used to enable touch input. One or more light sources, such as infrared (IR) light emitting diodes (LEDs), can direct radiation into an edge or side of the transmissive element and direct light to reflect from at least one other side or edge using total internal reflection (TIR). If a user places a finger at a position where the light reflects from an edge of the element, a portion of the light will be transmitted out of the element causing a reduction in the amount of light received to one or more light sensors. By monitoring losses for one or more light sources across one or more light sensors, locations at which losses occur can be determined. These locations can correspond to various types of user input.

  • Patent number: 9086763
    Abstract: A device implements a method for estimating the application force of a touching object onto a touch surface in an FTIR-based projection-type touch-sensing apparatus. The apparatus generates projection signals representing radiation that has propagated on a plurality of propagation paths by total internal reflection (TIR) inside a transmissive panel beneath a touch surface of the transmissive panel such that a touching object on the touch surface causes attenuation (frustration) of at least one of the projection signals. The device generates a time series of force values, which represent the application force, based on a time series of magnitude values, which represent a magnitude of a peak in two-dimensional interaction patterns generated by image reconstruction processing of the projection signals, the peak corresponding to the touching object on the touch surface. The force estimation may involve one or more corrections.

  • Patent number: 9086741
    Abstract: A user input device is described. In an embodiment the user input device is hand held and comprises a sensing strip to detect one-dimensional motion of a user's finger or thumb along the sensing strip and to detect position of a user's finger or thumb on the sensing strip. In an embodiment the sensed data is used for cursor movement and/or text input at a master device. In an example the user input device has an orientation sensor and orientation of the device influences orientation of a cursor. For example, a user may move the cursor in a straight line in the pointing direction of the cursor by sliding a finger or thumb along the sensing strip. In an example, an alphabetical scale is displayed and a user is able to zoom into the scale and select letters for text input using the sensing strip.

  • Patent number: 9081440
    Abstract: The present invention provides a method and device for writing on a capacitive touch screen, which includes a guarding pattern and a conductive strip pattern exposed from each other, and a stylus. The conductive strip pattern includes a plurality of first conductive strips provided with a driving signal and a plurality of second conductive strips that provide mutual capacitive coupling signals, and the guarding pattern is provided with a DC signal. The stylus has a conductive pen head and a pen body. When the human body holding the pen body is not electrically coupled to the conductive pen head, the location of the conductive pen head can be determined by sufficient change in capacitive coupling caused by the conductive pen head capacitively coupling to the guarding pattern and the conductive strip pattern.
