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.

摘要翻译：根据本发明的液晶显示装置包括具有并排布置的信号线和扫描线的像素阵列单元1，驱动信号线的信号线驱动电路2，驱动扫描的扫描线驱动电路3 行，输出从传感器提供的拾取图像数据的信号处理输出电路4以及同步信号发生电路5.当手指接近时，在拾取图像数据中获得的黑白变化或者与像素阵列单元1接触，并且考虑到环境亮度来识别手指的坐标位置。因此，无论周围环境是明亮还是暗，可以高精度地检测坐标位置。此外，当进行坐标检测时，未检测到与所有像素相对应的拍摄图像数据，而是在信号线方向和扫描线方向上每多个像素检测到拾取图像数据。因此，可以缩短检测坐标所花费的时间。

摘要： In order to allow information input using light in both the cases of strong outside light and weak outside light, two or more types of light-sensing elements having different optical sensitivities are arranged in a picture element region. For example, there are alternately arranged rows having arranged therein picture elements 21 provided with low-sensitivity light-sensing elements, and rows having arranged therein picture elements 22 provided with high-sensitivity light-sensing elements. This constitution makes it possible to perform optical information input using the high-sensitivity light-sensing elements in the case of weak outside light, and to perform optical information input using the low-sensitivity light-sensing elements in the case of strong outside light.
