Problems solved by technology

[0004] To sum up, the existing light-shielding materials, when the process temperature is in the range of 230°C to 300°C, will cause aging and yellowing degradation, the life of the material will be greatly shortened, and the aesthetics and reliability of the touch panel will also be affected.
The above problems have hindered the technical promotion and application of single-layer glass touch panels

Abstract

The invention provides a touch panel and a shading material thereof. The shading material is used to coat the edge of a glass substrate of the touch panel. The shading material contains silica gel and titanium dioxide powder, and titanium dioxide powder is mixed in silica gel, wherein silica gel is selected from methyl-series silica gel or benzene-ring-series silica gel, and addition ratio of titanium dioxide powder is in the scope of 10 wt%-60 wt% of the total weight of the shading material. The invention also provides another shading material used to coat the edge of the glass substrate of the touch panel. The shading material contain silica gel and carbon black powder, and the carbon black powder is mixed in silica gel, wherein silica gel is selected from methyl-series silica gel or benzene-ring-series silica gel, and addition ratio of carbon black powder is in the scope of 0.1 wt%-3 wt% of the total weight of the shading material. The invention also provides the touch panel comprising one of the above shading materials.

Description

technical field [0001] The invention relates to a touch panel and its light-shielding material. Background technique [0002] With the evolution and development of touch technology, in order to save the space occupied by input and control interfaces in many consumer electronic products, the application of touch panels is becoming more and more common, and the volume of touch panels is required to be thinner and lighter. In order to solve the volume problem of the double-layer glass touch panel and the problem that the overall light transmittance decreases because the double-layer glass touch panel uses an optical adhesive layer to bond two glass substrates, the predecessors proposed a single-layer glass touch panel. panel technology. [0003] Generally speaking, in the single-layer glass touch panel process, after the light-shielding material is coated and cured on the glass substrate, the subsequent process includes the process of setting the touch circuit layer and deposi...
