Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention discloses a capacitive touch screen, which comprises a substrate, an electrode layer and a plurality of photo-sensitive resist protecting blocks, wherein the electrode layer is formed on the surface of the substrate; the photo-sensitive resist protection blocks are arranged on the electrode layer; the electrode layer comprises a first direction electrode, a second direction electrode and a plurality of wiring bridges; the first direction electrode and the second direction electrode are isolated and kept insulated through the wiring bridges; and the photo-sensitive resist protecting blocks are arranged on the electrode layer at certain intervals, and cover the wiring bridges. According to the capacitive touch screen, the photo-sensitive resist protecting blocks which are arranged at certain intervals are used for protecting the wiring bridges acting key roles; and compared with the conventional SIO2 full page protection, the capacitive touch screen has the advantage of high insulating performance. The invention further provides a preparation method for the capacitive touch screen.

Description

【Technical field】 [0001] The invention relates to the field of display devices, in particular to a capacitive touch screen and a preparation method thereof. 【Background technique】 [0002] As a new information input method, capacitive touch screen is widely used in various information display products, such as touch screen mobile phones, GPS navigation systems, etc. [0003] The electrode layer of the traditional capacitive touch screen adopts SIO 2 Full page protection. However, with SIO 2 The protective electrode layer has poor insulation. 【Content of invention】 [0004] Based on this, it is necessary to provide a capacitive touch screen with better insulation and a preparation method thereof. [0005] A capacitive touch screen, comprising a substrate, an electrode layer arranged on the surface of the substrate, and a plurality of photosensitive glue protection blocks arranged on the electrode layer; [0006] The electrode layer includes a first direction electrode,...
