Problems solved by technology

Due to the short distance between the touch line 071 and the common electrode layer 05, the load between the touch line 071 and the common electrode layer 05 is relatively large, and the signal of the touch line is interfered, which reduces the touch performance

Abstract

The invention discloses a touch display panel, a driving method thereof, and a touch display device, which belong to the field of display technology and include: a display area and a non-display area, and the display area includes a plurality of pixels; a first substrate and a second substrate arranged opposite to each other Substrate; the display area of ​​the first substrate includes a pixel electrode layer and the first electrode layer, and the display area of ​​the second substrate includes a touch electrode layer. By electrically connecting the touch electrodes on the touch electrode layer to the first electrodes on the first electrode layer, the coupling capacitance between the touch electrodes and the first electrodes is reduced, and compared with the prior art, the touch wiring is reduced Load, improve touch performance, at the same time, increase the penetration rate of the display panel, and reduce the cost of manufacturing the touch display panel.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to a touch display panel, a driving method thereof, and a touch display device. Background technique [0002] See figure 1 , figure 1 A touch display panel with a vertical electric field display mode provided for the prior art, including an array substrate 01 and a color filter substrate 06, the array substrate 01 including a first substrate 08, a storage electrode layer 03, a thin film transistor array 02 and a pixel electrode layer 04. The color filter substrate 06 includes a common electrode layer 05, a second substrate 09, and a touch electrode layer 07. The storage electrode layer 03 and the common electrode layer 05 are all transparent metal oxides (such as ITO). The researchers found through experiments that the penetration rate of the touch electrode layer 07 covered alone on the color filter substrate 06 is 94%, and the penetration rate of the secon...
