  • Patent number: 6894671
    Abstract: A display apparatus is capable of adapting sufficiently to an increase in the display frequency even when using an optical modulation element which has a fairly low response speed and can rewrite an image at a high speed. The display apparatus separately performs mapping of display data for an optical modulation element of each pixel and application of gradation information. The display apparatus divides a display period of one frame into a plurality of sub-frames, controls the input value for the optical modulation element independently per each sub-frame in the plurality of sub-frames, and displays an image with a gradation display using the optical modulation element.

    Abstract: The present disclosure is directed to a system for providing restrained, streamlined access to a computerized information source. The system—which works in association with a multipurpose computer—includes a discrete article, such as an advertising specialty like a mouse pad, having facilities to receive a user input and, in turn, generate a unique predetermined signal based on the input. The system further includes software for configuring the computer to respond to each unique predetermined signal by executing one or more commands, as selected and stored within the software. Each configuration can be dynamically locked such that the commands to be executed upon the unique input are not alterable without an authorization mechanism, such as a password. The software also responds to receipt of one of the unique predetermined signals by executing the commands associated with the received signal. A method for performing same is also disclosed.

  • Patent number: 6753839
    Abstract: The present invention provides an electro-optical panel that is capable of effectively exhibiting the features of the construction in which two transistor elements are used per pixel, and an electronic device using the electro-optical panel. A pixel includes a P-channel thin-film transitor (TFT) in which the gate electrode is connected to a scanning line, and an N-channel TFT in which the gate electrode is connected to a scanning line. When the P-channel TFT and the N-channel TFT are turned on, the voltage of an image signal supplied to a data line is written into a holding capacitor HC and a holding capacitor LC. The holding capacitor HC is connected to the drain electrode of the N-channel TFT. Also, the holding capacitor HC is connected to the drain electrode of the P-channel TFT via a wiring line L. Since the wiring line L is formed of a low-resistance material, the time constant when the image signal is written into the holding capacitor HC via the P-channel TFT can be decreased.
