DISPLAY PANEL HOUSING OPTICAL SENSOR, DISPLAY DEVICE USING THE DISPLAY PANEL AND METHOD FOR DRIVING DISPLAY PANEL HOUSING OPTICAL SENSOR

摘要

Provided are a display panel, which houses an optical sensor and corrects output from the optical sensor corresponding to a change of environmental temperature, and a display device using such display panel. The display panel housing the optical sensor is provided with an active matrix substrate (100) having a pixel region (1) wherein pixels are arranged in matrix. The optical sensor (11) is formed in at least some pixels in the pixel region (1). The display panel housing the optical sensor is provided with a temperature sensor (9) for detecting the ambient temperature of the optical sensor (11), and a signal processing circuit (8) for correcting the output from the optical sensor (11) corresponding to the ambient temperature detected by the temperature sensor (9).
