DISPLAY DEVICE INCLUDING OPTICAL SENSOR

摘要

PURPOSE: A display device including an optical sensor is provided to reduce the deviation of a sensing gate off voltage applied to a sensing gate driver. CONSTITUTION: A display device includes a first display panel(100), a second display panel(200), an electro-optical active layer(3) and a sensing gate driver. The second display panel faces the first display panel and includes an optical sensor. The electro-optical active layer is located between the first display panel and the second display panel. The sensing gate driver includes a first sensing gate driver and a second sensing gate driver, and transmits a sensing gate signal to the optical sensor. A first sensing gate off voltage applied to a first contact member of the first sensing gate driver is actually equal to a second sensing gate off voltage applied to a second contact member of the second sensing gate driver.
