Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] The embodiment of the present application provides a touch display panel 01, such as figure 1 As shown, the above-mentioned touch display panel 01 includes an array substrate 100 and a box substrate 101 oppositely arranged, and a liquid crystal layer 102 located between the array substrate 100 and the box substrate 101 .
[0033] In addition, the above-mentioned touch display panel 01 also includes: figure 2 A common electrode 103 and a plurality of p...

Embodiments of the present application provide a driving method for a touch display panel and a touch display device, which relate to the field of display technology and are used to solve the problem of insufficient charging time for a line of sub-pixels in a touch display screen when the touch signal and display signal are output in time division The problem. The driving method of the touch display panel includes providing a single-frequency sinusoidal signal y to each electrode block in the common electrode in a display period; the electrode block serves as a touch electrode and forms a self-capacitance with the ground terminal; the display period includes N display stage; each display stage has M image frames; the refresh rate of the display cycle is greater than or equal to the refresh rate threshold A; the refresh rate threshold is the maximum refresh rate recognizable by human eyes. Provide data signals to a plurality of pixel electrodes; the electric field formed by the pixel electrodes and the common electrode drives the liquid crystal molecules in the liquid crystal layer to flip, and touches the display panel for display. In a display period, the average brightness value of any sub-pixel in the touch display panel is the same as the target brightness value of the sub-pixel.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of a touch display panel and a touch display device. Background technique [0002] The touch screen panel (Touch Screen Panel) is gradually permeating people's life. At present, during the touch display process of the touch display screen, the touch signal and the display signal are time-divisionally output. However, for a display panel with a higher resolution, the number of sub-pixels in one row is larger. In this way, when the touch signal and the display signal are output in time-division, the time for a row of sub-pixels to receive the display signal is relatively short, causing some sub-pixels to be insufficiently charged. Contents of the invention [0003] Embodiments of the present invention provide a method for driving a touch display panel and a touch display device, which are used to solve the problem of insufficient charging time for a ro...
