Abstract

The invention discloses a touch display device and a driving method of the touch display device, and relates to the field of displaying. The contact reporting up rate of the touch display device can be improved. According to the driving method of the touch display device, a time display period at least comprises two sub time display periods, a touch time period at least comprises two sub touch time periods, and one sub touch time period is within the interval between every two adjacent sub time display periods; a control signal controls the touch display device to enter the sub touch time periods from the sub time display periods, and the touch display device sends out a touch signal; the control signal and a driving signal control the touch display device to enter the sub time display periods from the sub touch time periods, and display of images is performed.

Description

technical field [0001] The present invention relates to the display field, in particular to a touch display device and a driving method thereof. Background technique [0002] Digital equipment has become an indispensable and important element in people's life and production. As a video signal output terminal of digital equipment, the display device is used to directly transmit information to the operator, and is an indispensable device. With the development of science and technology, the function of the display device is not limited to receiving video signals for display, but has the function of controlling command input, that is, the existing touch display device can directly input commands through the screen, and can even replace the keyboard. and other accessories for input. [0003] In the process of implementing the present invention, the inventors found that in the prior art, the touch display device only scans between the refreshes of two display images to detect wh...
