Problems solved by technology

[0004] The current mainstream OGS touch screen structure is basically formed on the same layer as the driving line and the sensing line, one of which is continuous, and one of them is connected to each other by a metal bridge (or ITO bridge). One of the factors that make the process complex and product quality difficult to control, and this bridge structure is very prone to breakdown of the bridge due to electrostatic discharge (ESD), which affects the touch function; on the other hand, the metal bridge structure under light It is easier to see the whitening of the metal connecting wire, which affects the transmittance and display quality

Abstract

An embodiment of the invention discloses a touch screen and a production thereof and a touch display device and relates to the display field. The bridging is not required, the transmittance is high, the technological process is simple, the production cost can be reduced, and the yield of mass production is high. The touch screen comprises a transparent substrate, a first transparent conductive layer, an insulating layer and a second transparent conductive layer; the patterned first transparent conductive layer, the patterned insulating layer and the patterned second transparent conductive layer are formed on the transparent substrate in turn; a plurality of driving wires are formed in one of the first transparent conductive layer and the second transparent conductive layer and a plurality of sensing wires are formed in the other conductive layer; patterns of the insulating layer are as same as those of the first transparent conductive layer or the second transparent conductive layer.

Description

technical field [0001] The invention relates to the display field, in particular to a touch screen, a manufacturing method thereof, and a touch display device. Background technique [0002] Touch monitors are developing rapidly and have gradually developed into mainstream flat panel displays. At present, touch displays are mostly made of a touch screen with touch function attached to the display panel, and the touch screen mostly uses capacitive sensing. or other objects) approach or touch, it will affect the capacitance between the driving line and the sensing line that crosses near the touch point, and the position of the touch point can be identified by detecting the capacitance change between the driving line and the sensing line. [0003] As consumers demand thinner touch displays, technicians have developed various technologies to manufacture thinner products with better display quality. Among them, the one glass solution (OGS) technology is an important development ...
