摘要： In the conventional method of achieving a fast response of a liquid crystal panel, even if the frame rate or the ambient temperature varies, if the image data are the same, the correction value will always be constant; accordingly, the conventional method is impossible of a correction in accordance with the environmental conditions in use. The liquid crystal display of the invention is provided with a plurality of look-up tables, each of which outputs a correction data for correcting an image data to increase the response speed of transmittance of the liquid crystal panel by using the two inputs of the input image data and the image data one frame before that an image memory storing the input image data outputs. The liquid crystal display selects one of the look-up tables in accordance with a frame rate that a frame rate detection circuit detects from the input image data, generates the correction data, and drives the liquid crystal panel using this correction data; thereby, the method of the invention increases the response speed in a change of the gradation.

摘要： A driving method for a display device that includes: plural read signal lines; plural selectors connected to the read signal lines; plural gate signal lines; a photo-sensor connected to one of the read signal lines based on whether the one of the gate signal lines are switched on; and a detection circuit that detects an output value of the photo-sensor and selectively establishes connections with the read signal lines based on whether the selectors are switched on, includes: switching on one of the selectors; switching on the one of the gate signal lines; and detecting the output value. A timing of switching on the one of the gate signal lines is delayed by a specific period from a timing of switching on the one of the selectors. An influence of switching noises to the detection of the output value remains during the specific period.

摘要： The present invention provides a display device capable of reducing cost by reduction in number of integrators. Signal lines (91 to 94, 95 to 98, 99 to 912, 913 to 916) are brought together into one line by means of signal lines (10a, 10b, 10c, 10d) to be connected to integrators (4a, 4b, 4c, 4d), respectively. Selector lines (71 to 74) orthogonal to the signal lines (91 to 916) are formed and connected to a selector driving circuit (3). An a-SiTFT (12) is formed at each of intersections: an intersection of the selector line (71) and the signal lines (91, 95, 99, 913); an intersection of the selector line (72) and the signal lines (92, 96, 910, 914); an intersection of the selector line (73) and the signal lines (93, 97, 911, 915); and an intersection of the selector line (74) and the signal lines (94, 98, 912, 916). The selector lines (71 to 74) are driven in sequence by the selector driving circuit (3) in the frame period.
