Problems solved by technology

However, when the low light transmission layer is in direct contact with the existing non-black decorative layer, the low light transmission layer is likely to affect the non-black decorative layer, for example, the low light transmission layer may chemically react with the non-black decorative layer, or the low light transmission layer The material particle size of the light layer may be smaller than the material particle pores of the non-black decorative layer, resulting in the penetration of the low light-transmitting layer, thus causing the color of the non-black decorative layer to be different from its original color (that is, the color is impure or yellowed), making the touch screen The overall texture of the panel is greatly reduced

Abstract

The utility model provides a decorative cover plate and a touch control panel of the decorative cover plate. The decorative cover plate comprises a substrate, an outward-displayed decorative layer, an auxiliary light shielding layer and a buffer layer, wherein the outward-displayed decorative layer is configured on the substrate, and the auxiliary light shielding layer is configured on one side, away from the substrate, of the outward-displayed decorative layer. The buffer layer is at least configured between the outward-displayed decorative layer and the auxiliary light shielding layer. The touch control panel further comprises a touch control sensing element and a transmission line. The touch control sensing element is configured on the substrate and at least located in a photic zone of the touch control panel. The transmission line is configured on one side, away from the substrate, of the auxiliary light shielding layer and electrically connected with the touch control sensing element.

Description

technical field [0001] The present invention relates to a decorative cover plate and its touch panel, and in particular to a decorative cover plate with a high light-shielding decorative area and its touch panel. Background technique [0002] In order to transmit signals, the touch panel needs to configure multiple transmission lines to connect with its sensing elements. However, in order to reduce the transmission impedance, visible metal wires are usually used, and black light-shielding materials are usually configured to shield these transmission lines. In order to maximize the effective display area, the transmission lines are usually arranged in the peripheral area of ​​the touch panel. At this time, the touch panel has a black decorative frame to cover the transmission lines. However, for users, the black decorative frame does not necessarily meet the user's demand for appearance, so the industry puts forward the idea of ​​a non-black decorative frame. [0003] Since ...
