摘要： A liquid crystal display apparatus according to the present invention includes a pixel array unit 1 having signal lines and scanning lines respectively arranged side by side, a signal line drive circuit 2 which drives the signal lines, a scanning line drive circuit 3 which drives the scanning lines, a signal processing output circuit 4 which serially outputs the picked-up image data supplied from the sensors, and a sync signal generation circuit 5. A black-white change obtained in the picked-up image data when a finger is brought close to or brought into contact with the pixel array unit 1 is detected, and the coordinate position of the finger is identified taking the ambient brightness into consideration. Regardless of whether the surroundings are bright or dark, therefore, the coordinate position can be detected with high precision. Furthermore, when conducting the coordinate detection, the picked-up image data corresponding to all pixels are not detected, but the picked-up image data are detected every a plurality of pixels in both the signal line direction and the scanning line direction. Therefore, the time taken to detect the coordinates can be shortened.

摘要： In order to maintain display performance of a display device, the display device includes an optical sensor disposed across three sub-pixels of red, green and blue colors in each pixel. This configuration makes it possible to adjust the aperture ratios of the respective sub-pixels, and thus to make the amount of light passing through the respective sub-pixels closer to one another. In other words, the white balance can be maintained.

摘要： A capacitor charged beforehand is discharged according to a light surrounding a display unit. A data is decreased similarly to the voltage between the electrodes of the capacitor. A trigger signal is outputted if the data becomes equal to or less than a threshold value. A clock signal whose cycle of changing levels gradually becomes long is generated. A count value is updated at each change of the clock signal's level and the updated count value is outputted. The count value is sampled when the trigger signal is outputted.
