可触摸检测显示装置及其驱动方法

Touch detectable display device and driving method thereof
Abstract:
A display device is disclosed which includes: a display panel; a lighting unit to illuminate the display panel and having a state in response to a lighting control signal; a pressure sensing unit generating a first sensor output signal according to a touch on the display panel; a light sensing unit receiving light from the lighting unit and ambient light and generating a second sensor output signal according to the touch on the display panel; a sensor scanning driver outputting sensor scanning signals to the pressure sensing unit and the light sensing unit in response to a sensor scanning control signal; and a sensing controller generating the lighting control signal and the sensor scanning control signal based on the first and the second sensor output signals and outputting the lighting control signal to the lighting unit and the sensor scanning control signal and the sensor scanning driver.
