Abstract: A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixels 1 and a plurality of optical sensors 2 which are arranged in a row direction and a column direction. The optical sensors 2 are provided to be associated with pixels 1 in every other row (e.g., to be associated with pixels 1 in even rows). A panel drive circuit 16 performs one-line inversion drive and reads signals based on the amounts of received light, from the optical sensors 2. Since the outputs from the optical sensors 2 change in the same direction due to the influence of display data, stripe noise resulting from the switching of the polarities of voltages written into pixel circuits 3 is prevented from occurring in an image generated based on the outputs from the optical sensors 2.

A liquid crystal panel with built-in sensors (11) includes, in a pixel array (18), a plurality of pixel circuits and a plurality of optical sensors which are arranged two-dimensionally. A panel drive circuit (17) writes signals generated according to display data D3 into the pixel circuits, and reads signals generated according to the amounts of received light, from the optical sensors. An image processing unit (12) switches display data which is used before reading by the panel drive circuit (17) is performed, to fixed data suitable for image input. For the fixed data, white image data or blue image data is used.

Abstract: A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixel circuits 1 and a plurality of optical sensors 2 which are arranged two-dimensionally. Infrared light transmitting filters 3 that allow infrared light to pass therethrough and cut off visible light are respectively provided in paths of light entering the optical sensors 2. Accordingly, an image obtained by the optical sensors 2 is prevented from being influenced by visible light included in outside light or backlight light and thus a touch position is detected with high accuracy, based on an image that is not influenced by visible light included in a large amount in outside light or backlight light. Instead of the infrared light transmitting filters 3, a light-shielding film having the same property 3 may be used.

Abstract: When a decryption-key request is transmitted from a client computer to a management server via a network apparatus, the network apparatus instead of the client computer adds location information to the decryption-key request. When the decryption-key request reaches the management server, location information stored therein is compared with location information associated with the decryption-key request. When the two pieces of the location information are the same, a decryption key is transmitted to the client computer. Thus, only when the management server receives the decryption-key request via the network apparatus which adds the specific location information to the decryption-key request, the management server transmits the decryption key to the client computer. This allows the encrypted data to be accessed within a specific area.

Abstract: The present invention provides a method in which the physical connection information and the logical network configuration information are kinked to the status of spanning tree, and the status of spanning tree is displayed with the physical connection and the logical network configurations. The method can provide the better recognition about not only intended the physical and logical configurations but the status of spanning tree to a network administrator. Therefore, the network administrator can integrally recognize the status of the network and the failure in the network will be analyzed easily to recover the network to normal state in shorter time.

Abstract: In a data transfer method and apparatus of the present invention, multiple data frames are received from a preceding node of a network of communication units, and the received data frames are routed to a next node of the network. It is detected whether each of the multiple data frames is addressed to another communication unit. It is detected whether the data frames that are detected as being addressed to another communication unit contain identical messages. The data frames that are detected as containing different destinations and identical messages are assembled into an integrated data frame, so that the integrated data frame is transmitted to the next node. A selected next-node equipment identifier is supplied, which indicates a selected next-node communication unit of the network that receives the integrated data frame.
