摘要： A liquid crystal module comprises a liquid crystal panel including mutually orthogonal row electrodes and column electrodes and a liquid crystal layer sealed between the electrodes as a display element, a row electrode driving circuit driving the row electrodes of the liquid crystal panel, and a column electrode driving circuit driving the column electrodes. A detecting electrode detects scanning signals applied to the row and column electrodes of the liquid crystal panel by electrically coupling to the electrodes with electrostatic coupling capacity. A coordinate detecting circuit converts the signals obtained from the detecting electrode into row and column coordinates. A correction arithmetic circuit corrects positional differences by using correction parameters of the device which have been obtained from output values of the coordinate detecting circuit beforehand. The display-integrated coordinate input device improves detection precision at the edges of a matrix panel.

摘要： A compact and inexpensive LCD is provided by improving a drive method for compensating a crosstalk using a compensating pulse added to a signal voltage so that a drive IC and a periphery of the LCD panel are reduced in size. Only one of positive and negative compensating pulses is added in accordance with a predetermined period. Alternatively, the two compensating pulses are added at different times from each other in one horizontal scanning period. The compensating pulse preferably has a waveform including low frequency components. A width or a height of the compensating pulse varies in accordance with a location of the signal electrode, display pattern or other factors.
