Abstract
The present invention relates to a resistance touch screen with a shielding layer, which comprises a transparent base layer (1), a transparent conducting film layer plated on the upper surface of the transparent base layer (1), and a transparent surface layer (2) covered on the transparent conducting film layer, wherein the inner surface of the transparent surface layer (2) is plated with a transparent conducting film layer (4). The two transparent conducting film layers are isolated by fine transparent isolation points (7). The resistance touch screen also comprises a transparent conducting film layer (5) which is plated on the lower surface of the transparent base layer (1), and is connected to the ground (10) of an application system matched with the touch screen to work. The resistance touch screen can effectively solve the problems of reading dithering of a touch screen controller and flying strokes when people write on the touch screen by hands, etc., and the problems are caused by unstable sampling voltage of the touch screen because of external disturbance.
