A touch screen and its manufacturing method and a mobile terminal

Abstract

The application discloses a manufacturing method of a touch screen. The manufacturing method includes the following steps: forming conductive layers on a front side and a back side of a transparent substrate; separately applying a positive photoresist and a negative photoresist on the conductive layer on the front side of the transparent substrate and on the conductive layer on the back side; placing a mold corresponding to an electrode pattern to be manufactured on the transparent substrate, and simultaneously exposing the positive photoresist and the negative photoresist by using a light source located above the mold; developing and thermally baking the positive photoresist and the negative photoresist; and etching and demolding the conductive layer on the front side of the transparent substrate and the conductive layer on the back side to form a touch screen of which the front side has a first electrode pattern and the back side has a second electrode pattern. The shape and locationof the solid part of the second pattern are the same as the shape and location of the gap part of the first pattern, so that the phenomenon that the gap between ITO patterns is displayed to users canbe avoided, and the user experience can be improved. The application also discloses the touch screen and a mobile terminal.

Description

technical field [0001] The invention belongs to the technical field of display products, and in particular relates to a touch screen, a manufacturing method and a mobile terminal. Background technique [0002] With the improvement of people's living standards, mobile terminals have developed faster and faster, and people's requirements for them are getting higher and higher. In order to meet people's increasing consumption needs, technicians are studying how to further improve the use of consumers. experience. [0003] The touch screens used in existing mobile terminals often see some pattern designs under the black background displayed. This phenomenon is called shadowing, such as figure 1 as shown, figure 1 It is a schematic diagram of the pattern of the existing touch screen. The reason for it is that there is a gap 102 between adjacent ITO patterns 101, and the ITO pattern and the transparent substrate have different reflectivities, which allows consumers to see the pa...

[0003] The touch screens used in existing mobile terminals often see some pattern designs under the black background displayed. This phenomenon is called shadowing, such as figure 1 as shown, figure 1 It is a schematic diagram of the pattern of the existing touch screen. The reason for it is that there is a gap 102 between adjacent ITO patterns 101, and the ITO pattern and the transparent substrate have different reflectivities, which allows consumers to see the pattern design from the outside , reducing the consumer experience
