Touch control display panel and touch control display device

Abstract

The invention provides a touch control display panel and a touch control display device. The touch control display panel comprises a pixel array and a first touch control electrode layer, wherein the pixel array comprises a plurality of sub pixel arrays; each sub pixel array comprises a plurality of sub pixels arranged in the first direction and the second direction; the first touch control electrode layer comprises a plurality of first touch control electrodes; a first carving seam extending in the first direction is formed between every two first touch control electrodes; each first touch control electrode correspondingly covers one sub pixel array; in the plurality of sub pixels adjacent to each first carving seam, for each sub pixel array, the adjacent sub pixel in the first direction correspond to different colors. The touch control display panel and the touch control display device provided by the invention can solve the display problem of visible carving seams.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] With the development of human-computer interaction technology, touch technology is increasingly used on various displays. Capacitive touch technology is widely used due to its advantages of wear resistance, long life, low maintenance cost for users, and support for gesture recognition and multi-touch. [0003] Capacitive touch technology can be divided into self-capacitive touch technology and mutual-capacitive touch technology according to the detection method of capacitance between different objects. Self-capacitive touch technology detects the presence, position, and motion of an input object on a touch screen based on changes in capacitance between the input object and electrodes. The mutual capacitive touch technology detects the existence, position and movement of an input object on t...

Problems solved by technology

[0006] 1) When etching the electrode layer 120 to form multiple electrodes 121, the slit 122 between the electrodes 121 may be too large due to improper etching (over-etching). When the slit 122 is too large, the electrodes 121 cannot completely cover The sub-pixels adjacent to the slit 122 cause light leakage at the corresponding positions of the sub-pixels adjacent to the slit 122, thereby causing the slit 122 to be visible and affecting the display effect of the touch display panel 100;

[0007] 2) For the touch display panel 100 using liquid crystal technology, since the positions of its sub-pixels are defined by the openings of the black matrix on the color filter substrate, when the alignment between the array substrate and the color filter substrate is improper, the opening of the black matrix will be The color-resisting material provided at the slit 122 partly overlaps with the above-mentioned slit 122, and then a color shift occurs at the slit 122, which affects the display effect of the touch display panel 100.
