Problems solved by technology

[0005] However, the existing capacitive touch screen has a small original touch signal and a small signal-to-noise ratio, resulting in a touch effect that is not sensitive enough, thus bringing consumers a poor user experience. At present, the industry usually adopts the method of improving chip capabilities. To enhance the original touch signal obtained by the processor, however, this method is technically difficult and costly. Therefore, the present invention proposes a method for enhancing the touch control obtained by the processor by optimizing the pattern design of the touch electrode. Control the original signal, improve the signal-to-noise ratio, and then improve the response sensitivity of the touch screen

Abstract

The invention provides a capacitive touch screen. Lateral capacitors in a plurality of lateral capacitance areas around an interactive capacitor can be increased by performing special pattern design on a touch induction electrode and a touch driving electrode, an electric field intensity on the touch screen surface is improved, thereby enhancing an original signal acquired by a touch processor, improving signal-to-noise ratio, and then improving the touch sensitivity and optimizing the touch experience.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a capacitive touch screen. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Currently, touch panels can be classified into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel according to their composition and structure. Wherein, the plug-in touch screen is produced separately from a touch screen and a liquid crystal display (LCD), and then bonded together to form a liquid crystal display with a touch function. Covering the surface touch screen is to directly make touch components on the side of the color film substrate of the liquid crystal display facing away from the liquid crystal layer. Compared with the external touch screen covering the surface touch screen, the thickness of the entire touch screen can be reduced and the light transmittance...
