摘要： The present invention relates to an information processing system using a coordinate detection device and displays, and more specifically to an input-display integrated information processing system which allows the displays to be carried like paper and to be freely laid out and stacked together on a desk (coordinate input device). The system includes a layout determining unit for determining a layout of the display on said coordinate detection device, wherein the layout determining unit further comprises a display position coordinate detector that detects where in the coordinate space of the coordinate detection device the display for displaying an information is located, and a coordinate converter that converts the information into display coordinates. The layout determination is done by using markers attached to three of the four corners of the display.

摘要： A liquid crystal active matrix display device includes a first substrate having a thin film transistor formed thereon. A light-screening film 1 is located on the first substrate in a manner to be overlapped with an ITO. The display device includes a second substrate having a color filter and a light-screening film 2 formed thereon. The second substrate is opposed to the first substrate.

摘要： The object of the invention is to provide a drive method suitable for driving a fast-responding STN liquid crystal display device which ensures a minimized cross talk and improved contrast in display. The drive method comprises a memory means for storing display data corresponding to a plurality of lines, a function generating means for generating a drive function for the row electrodes, an arithmetic means for computing the outputs from the foregoing means, a column electrode drive means for driving the column electrodes in dependency on the output from the arithmetic means, and a row electrode drive means for driving the row electrodes in accordance with respective row electrode drive functions. As a voltage function to be applied to each row during drive operation, a sum of a plurality of orthogonal functions is utilized. Thereby, degradation in contrast due to display patterns as well as the cross talk can be minimized. Further, arithmetic operation can be simplified in gradation display since application of a compensating voltage waveform is no more required.
