DISPLAY DEVICE WITH OPTICAL SENSOR

摘要

A liquid crystal panel (11) incorporating sensors includes a plurality of pixels (1) arranged in rows and columns and a plurality of optical sensors (2), in a pixel array (17). The optical sensors (2) are provided corresponding to the pixels (1) in every other row (for example, corresponding to the pixels (1) in the even-numbered rows). A panel driving circuit (16) performs one-line inversion driving and reads out a signal according to an amount of light received from the optical sensors (2). Since the output of the optical sensors (2) changes in the same direction under the influence of display data, stripe noise, which is caused by switching between the polarities of write voltage of a pixel circuit (3), can be prevented from being generated in an image which is formed based on the output of the optical sensors (2).
