Problems solved by technology

[0003] However, because the thickness of the external touch panel with the touch screen set outside the display panel is very large, it does not conform to the current development trend of thinner display devices. Therefore, in many portable display devices, embedded touch panels tend to be used. Panel, which integrates the touch structure into the display panel
[0004] For the embedded touch display panel, it includes both the touch driver part and the display driver part; in the drive control of the existing embedded capacitive touch display panel, the reporting rate is not high, which results in low touch accuracy

Abstract

The invention discloses a method and a device for controlling a touch display panel, and a display device and aims to realize functions of display and touch control of an embedded capacitive display panel and improve point report rate of touch control. The method includes: dividing time for displaying each image of the embedded capacitive touch display panel into at least two control time periods, with each control time period comprising a display time period and a touch control time period; in the display time periods, not applying or applying signals for display to a touch control driving electrode of the touch display panel, and allowing a touch control inductive electrode to be free of signal input; in the touch control time periods, sequentially applying the touch control driving signals to the touch control driving electrode, and allowing the touch control inductive electrode to couple voltage signals of the touch control driving signals and output.

Description

technical field [0001] The present invention relates to the field of liquid crystal technology, in particular to a control device and method for an embedded capacitive touch display panel and a display device. Background technique [0002] The basic structure of a traditional touch display panel includes: a display panel (such as a liquid crystal panel) and a touch screen placed outside the display panel. Such as figure 1 As shown, the liquid crystal panel includes an array substrate 13 and an opposite substrate 11 arranged oppositely, and a liquid crystal layer 12 is filled between the array substrate 13 and the opposite substrate 11; a touch screen 14 is attached to the outside of the liquid crystal panel, thereby obtaining Traditional touch display panel. Wherein, the color filter layer of the liquid crystal panel can be fabricated on the opposite substrate 11 to form the color filter substrate, or can be directly fabricated on the array substrate 13 . [0003] However...
