Embodiment Construction

[0010] The preferred embodiment of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0011] Such as figure 1 and figure 2 The shown resistance touch screen with shielding layer of the present invention includes: a transparent base layer 1 made of glass or hard plastic flat plate, a transparent conductive film layer 3 plated on the upper surface of the transparent base layer 1, and the outer surface covered on it is hardened 1. A smooth anti-scratch plastic transparent surface layer 2, the inner surface of the transparent surface layer 2 is coated with a transparent conductive film layer 4, and there are many small transparent isolation points 7 between the transparent conductive film layer 3 and the transparent conductive film layer 4 to insulate them. , and insulating glue 6 isolates the transparent isolation point 7 and the two layers of transparent conductive film from the outside world, it also includes: a tr...

Abstract

The resistive touch screen with shielding layer includes transparent base layer, transparent conducting film layer plated on the surface of the transparent base layer, the covering upper transparent surface layer with transparent conducting film plated to its inner surface, fine transparent insulating spots between the two layers of transparent conducting film, and one third layer of transparent conducting film plated to the lower surface of the transparent base layer and connected to the ground of the application system the touch screen is in. The said resistive touch screen has no troublesof jittered reading, flying hand written stroke, etc owing to outer interference to cause unstable sample voltage.

Description

technical field [0001] The present invention relates to touch screens, in particular to resistive touch screens. Background technique [0002] The prior art relates to a resistive touch screen attached to a flat panel display, which often causes reading errors of the touch screen controller due to interference from the flat panel display itself and other components, and even causes the touch screen to fail to work in severe cases. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and propose a resistive touch screen with enhanced anti-interference capability pasted on a flat panel display. [0004] The purpose of the present invention can be achieved by taking the following technical measures, designing and manufacturing a resistive touch screen with a shielding layer, which includes: a transparent base layer, a transparent conductive film layer plated on the upper surface of the transparent base layer, ...
