Problems solved by technology

[0003] Most of the existing touch screens are single-layer multi-point mutual capacitive touch screens. The touch screen sets the driving channel and the detection channel on one layer to form a single-layer touch design. cost, but the layout of the driving channel and the detection channel on the same layer leads to patterning of the touch film layer, which directly leads to the fact that the touch pattern can be observed by the human eye during the screen display stage, resulting in poor screen display effect and affecting the experience. question

Abstract

The invention belongs to the technical field of display, and provides a touch panel. The touch panel comprises a first insulating layer, a touch pattern layer, a second insulating layer and a patternmatching layer; the touch pattern layer is arranged on the first insulating layer; the touch pattern layer comprises multiple transversely distributed driving channels, multiple longitudinally distributed detection channels and multiple interval regions between the driving channels and the detection channels; the detection channels in the same longitudinal direction are connected into an integrated body; the driving channels are positioned between two adjacent detection channels; the second insulating layer is arranged on the touch pattern layer; the second insulating layer forms concave regions in the interval region positions; the pattern matching layer is arranged on the second insulating layer; the material of the pattern matching layer is the same as that of the touch pattern layer; the thickness of the pattern matching layer is consistent to that of the touch pattern layer; and the positive projection of the pattern matching layer on the second insulating layer coincides with theconcave regions. The touch panel is uniform in emergent rays and the touch pattern is not observed by human eyes in the display stage.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a touch panel, a method for manufacturing the touch panel, and a touch display device equipped with the touch panel. Background technique [0002] With the development of active matrix organic light emitting diode technology, users have higher and higher requirements for screen resolution. Therefore, more stringent requirements are placed on the optical display effect of the screen. [0003] Most of the existing touch screens are single-layer multi-point mutual capacitive touch screens. The touch screen sets the driving channel and the detection channel on one layer to form a single-layer touch design. cost, but the layout of the driving channel and the detection channel on the same layer leads to patterning of the touch film layer, which directly leads to the fact that the touch pattern can be observed by the human eye during the screen display stage, resulting in po...
