Embodiment Construction

[0022] The specific implementations of the touch screen, the manufacturing method thereof, and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] The thickness of each layer and the size and shape of the regions in the drawings do not reflect the real scale, and are only intended to illustrate the content of the present invention.

[0024] An embodiment of the present invention provides a method for manufacturing a single touch screen, such as figure 2 It includes the following steps:

[0025] Step S102 , a pattern of the bridge layer 3 and the peripheral wiring 4 is formed on the substrate 1 through a patterning process, such as Figure 3b As shown, the peripheral traces 4 only have graphics in the non-touch area B of the touch screen, and the bridge layer 3 has graphics in both the touch area A and the non-touch area B;

[0026] Preferably, before performing step S...

Abstract

The embodiment of the present invention discloses a touch screen, its manufacturing method and a display device. The method comprise the following steps: first, forming patterns of shielding layer on a substrate; then forming patterns of bridging layer and peripheral traces on the shielding layer by a single patterning process; thereafter, forming patterns of insulating layer on the peripheral traces; and finally, forming patterns of touch control electrode layer. In the present invention, the patterning of the bridging layer and peripheral traces can be achieved by a single patterning process using a mask plate, which reduces the number of patterning processes in the manufacturing process and improves the manufacturing efficiency of the touch screen thereby reducing the cost of production.

Description

technical field [0001] The present invention relates to the technical field of touch control, and in particular, to a touch screen, a manufacturing method thereof and a display device. Background technique [0002] With the rapid development of display technology, touch screens (Touch Screen Panel) have gradually spread throughout people's lives. At present, touch screens can be divided into resistive, capacitive, infrared, surface acoustic wave, electromagnetic, vibration wave induction and suppressed total internal reflection optical induction according to their working principles. Among them, capacitive touch screen is sought after by the industry as a new favorite due to its unique touch principle, high sensitivity, long life, high light transmittance and other advantages. [0003] At present, the widely used single-chip (OGS, One Glass Solution) touch module is to directly form a single-layer touch conductive film and sensor on the substrate, such as Figure 1a and F...
