Touch substrate as well as production method thereof and touch display panel

Abstract

The invention provides a touch substrate as well as a production method thereof and a touch display panel. The touch substrate comprises a base plate, a light resistor which is arranged on the base plate and a touch electrode layer, wherein the light resistor and the touch electrode layer are respectively arranged on the peripheries of a first surface of the base plate, and the touch electrode layer is arranged on a second surface of the base plate. According to the touch substrate, the light resistor and the touch electrode layer are arranged on different surfaces of the base plate, so that the broken wire caused when the touch electrode climbs an edge area of the base plate can be avoided, and the yield of the touch substrate and the performance of the product can be improved.

Description

technical field [0001] The invention relates to the display field, in particular to a touch substrate, a manufacturing method thereof, and a touch display panel. Background technique [0002] Existing touch substrates are divided into several types according to their working principles: capacitive, resistive, infrared, pressure sensing, etc. Among them, capacitive touch substrates are widely used, and are widely used in mobile phones, tablets and other fields. [0003] The traditional capacitive touch panel is to bond a layer of cover glass and a layer of touch glass through optical adhesive (OCA) to form a touch panel, that is, GG (Glass-Glass) structure, but with the development of touch technology , this structure can no longer meet the requirements of light, thin, and low-cost touch substrates, and it is gradually replaced by touch structures such as GF (Glass-Film), GFF (Glass-Film-Film), and OGS (On Glass Solution). [0004] Compared with touch structures such as GG, ...

Problems solved by technology

[0005] However, the high temperature resistance of the ink is poor. During the high temperature process of making OGS, the ink is easily affected by the high temperature and turns yellow, which affects the appearance.

OGS uses photoresist frame shading material, and white photoresist is used as frame shading material for aesthetics, but the white photoresist on the market is not yet mature and has poor shading effect. To achieve the same optical effect on the cover plate produced by the ink, the thickness of the white photoresist needs to be at least 15um and above, such as figure 1 and figure 2 As shown, the white photoresist layer 2 and the touch electrode layer 3 are arranged on the same surface of the substrate 1, because the white photoresist layer 2 needs a certain thickness, which will cause the touch electrode layer 3 and the white photoresist layer 2 to overlap. The position (that is, the climbing position) is prone to the possibility of disconnection, thereby affecting product performance
