Problems solved by technology

But the disadvantage is that it is difficult to make
Patents are prone to conflict;
[0005] see figure 2 , the single-sided (SITO) structure is mature and easy to manufacture, but the disadvantage lies in the size of the jumper and the overall parameters are not easy to control. The appearance does not meet the customer's requirements in a certain sense (the appearance will have jumping conductor layer glare and produce "pitting" phenomenon )

Embodiment Construction

[0024] See figure 1 It can be seen that the capacitive touch screen is provided with a glass substrate 6, one side of the substrate is provided with an ITO layer 5, and the substrate 6 is surrounded by metal lines 9 around this side. Each line of the ITO layer is wrapped with a POC insulating bridging layer 4, which is insulated The bridging layer 4 is covered with a jumping conductor layer 3. The jumping conductor layer 3 can be coated with ITO or metal conductive material. The jumping conductor layer 3 is also covered with a black film (BM) layer 1. Film layer 1 is used to shield the glare caused by the metal (mo / al / mo) jumping conductor. The pattern structure of the above-mentioned ITO layer 5, insulating bridge layer 4, jumping conductor layer 3, and black film layer 1 are the same and overlap each other to form the touch portion of the capacitive touch screen. In addition, the patterns of the jumping conductor layer 3 and the black film layer 1 are completely overlapped ...

Abstract

The invention discloses a capacitive touch screen which comprises a substrate, an ITO (indium tin oxide) pattern layer, an insulation bridging layer and a jumping conductor pattern layer. The ITO pattern layer is arranged on the substrate, the insulation bridging layer covers the ITO pattern layer, the jumping conductor pattern layer covers the insulation bridging layer, and a black membrane pattern layer covers the jumping conductor pattern layer. A black membrane (BM) of the touch screen is manufactured by the process, after being exposed, the black membrane is only etched and is not peeled off, a low glare effect can be achieved, a peeling-off manufacturing procedure can be omitted, and yield is improved. Besides, the black membrane (BM) is used for shielding high glare generated by the jumping conductor pattern layer, and accordingly the appearance is improved.

Description

Technical field [0001] The invention relates to a capacitive touch screen structure and its production process. Background technique [0002] At present, the touch screens produced on the market are mainly capacitive touch screens, which are mainly divided into two types: surface type and projection type. The projection type is also called inductive capacitive touch screen. The capacitive touch screen has a simple mechanical structure and does not require manual correction. , Adopting matrix structure, high accuracy, very suitable for use on portable electronic products. Therefore, capacitive touch screens occupy a major share of the market. The expensive production costs of capacitive touch screens have become the main reason for competition. In order to reduce production costs, under the condition of the same raw material prices, reducing manufacturing processes and providing effective output have become the biggest key to reducing costs. . [0003] In the capacitive touch scre...
