DISPLAY DEVICE PROVIDED WITH OPTICAL SENSOR

摘要

A liquid crystal panel (11) with a built-in sensor includes a pixel array (18) in which a plurality of pixel circuits arranged in a two-dimensional form and a plurality of optical sensors are provided. When the liquid crystal panel (11) is formed by CG silicon, the light receiving sensitivity of the optical sensor is high for blue light but becomes low for red light or green light. A display data processing unit (12) carries out correction to make a gray scale with a value that is less than a predetermined value high for a blue component contained in display data (D1). Further, the display data processing unit (12) corrects only data displayed in a recognition area set in a display screen out of the blue component. This function converts a display image into a recognizable image even when the display image is dark, detects a touch position correctively regardless of a display image, and can limit only the change of a display image by correction to the change of a specific color in a specific area.
