Abstract

The present invention provides a method for manufacturing an embedded touch panel and the embedded touch panel. The method for manufacturing the embedded touch panel includes the following steps: providing a base layer, the base layer includes an inner side; providing a light-shielding layer, The light-shielding layer is arranged on the inner side, and the light-shielding layer includes a light-shielding area and a plurality of holes; multiple metal traces are provided, wherein the multiple metal traces are arranged on the light-shielding area and do not cover the multiple holes; providing A conductive film layer, the conductive film layer covers the filter film layer, another part of the metal wiring and the light-shielding layer. The present invention also provides an embedded touch panel, which includes a base layer, a light-shielding layer, a plurality of metal wires, a filter film layer and a conductive film layer.

Description

technical field [0001] The invention relates to a method for manufacturing an in-cell touch panel, in particular to a method for manufacturing an in-cell touch panel with low cost and good transmittance. Background technique [0002] In modern society, products with touch screens (such as tablet computers, smart phones) are convenient and easy to use, so they are very popular among consumers. The traditional touch screen is designed as an on-cell structure. During the production process of the on-cell touch screen, the color filter (Color Filter) is placed near the outside (that is, it is used closer to the A color-resist layer and an indium tin oxide (Indium Tin Oxide, ITO) layer are pasted on the surface of the contact side). However, in one step of the existing surface-embedded touch screen manufacturing process, the color filter must be turned over, and the step of turning over is likely to cause scratches on the color filter or color resist layer, and The electrostati...
