Problems solved by technology

[0003] For example, in the prior art, the conductive glass prepared in the patent No. CN104834420A "a conductive glass for capacitive touch screen and its preparation process" has a transmittance of ≥ 88.5% and a reduced reflectivity. The capacitive touch screen of conductive glass improves the shadow removal effect while being ultra-thin. However, in this patent, the shadow removal effect is only performed through the shadow removal layers arranged on both sides of the glass substrate, and the shadow removal effect still needs to be further improved.
As another example, the patent No. CN106587655A "anti-reflection con

Description

technical field [0001] The invention relates to the technical field of glass panels of electronic display devices, in particular to high-transmission and shadow-eliminating conductive glass and a manufacturing method thereof. Background technique [0002] Capacitive touch screen is a development trend. Its preparation method is mainly to coat a layer of conductive film (that is, indium tin oxide, referred to as: ITO) on the surface of ordinary glass to make it conductive. This is conductive glass. Indium tin oxide transparent conductive film glass is a high-tech product obtained by sputtering indium tin oxide conductive film coating on ultra-thin glass and high-temperature annealing treatment by using planar magnetron technology. However, the current conductive glass either does not meet the requirements of resistance, or the uniformity of resistance is not good, or the light transmittance is too low, etc., and it does not have the function of shadow elimination, so it canno...
