Problems solved by technology
Since the display panel detects that there is a relatively long touch detection cycle at the touch position of the touch subject, when the display panel is applied to a vehicle display, the long touch detection cycle is likely to reduce the speed of the display panel's response to false touches. As a result, the response of touch detection is very slow, and the speed of touch detection cannot meet the needs of touch display devices

The invention discloses a driving method of a touch display device and the touch display device. The driving method comprises the following steps: acquiring a first preset duration of a display stagebetween adjacent touch stages in an image frame and a second preset duration of a display stage after the last touch stage in the image frame; according to the first preset duration of the display stage between every two adjacent touch stages, determining the first duration of the display stage between every two adjacent touch stages, and according to the second preset duration of the display stage after the last touch stage in the image frame, determining the second duration of the display stage after the last touch stage in the image frame; in the display stage, conducting display driving onthe touch display device according to the first duration and the second duration; in the touch control stage, applying the touch control driving signal to the touch control display device, so that the touch control sensing reaction time is shortened, and the touch control detection efficiency of the touch control display panel is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of a touch display device and a touch display device. Background technique [0002] Nowadays, touch display panels have been widely used by people. For example, smart phones, tablet computers, etc. have used touch display panels. Existing embedded touch technologies are mainly divided into two types: one is touch The detection circuit is on the liquid crystal box (On Cell) type, and the other is the touch detection circuit in the liquid crystal box (In Cell) type. [0003] In the prior art, when a touch display panel displays a frame, the touch stage and the display stage are set at intervals, and the noise detection stage is set after the last touch drive stage of each touch detection frame to perform noise detection. When there is a touch operation of the touch subject at a certain touch driving stage of the first touch detection frame of the display ...
