Abstract

The present invention provides a touch control display device and a driving method thereof. The touch controlled display device comprises a display unit, a touch control unit, and a detection and control unit. The display unit is designed to display images. The touch control unit is designed to receive pressure signals and control the display of the display unit in accordance with the pressure signals. The detection and control unit is designed to detect the working state of the touch controlled display device and switch on or switch off the touch control unit according to the working state of the touch controlled display device. The touch controlled display device can switch off the touch screen and reduce power consumption when the device is in idle state, and can avoid misoperations and enhance reliability of the touch screen display device. The present invention further provides a method for driving the touch controlled display device.
