Abstract

The invention relates to a touch panel and a preparation method thereof, a touch display screen and electronic equipment. The preparation method of the touch panel comprises the following steps: sequentially stacking a conductive layer and a photoresist layer on one side of a transparent substrate in a stacked mode, and performing exposing, developing and etching, so that the conductive layer is made to form a conductive pattern layer with a plurality of conductive patterns, and the photoresist layer is made to form first protruding parts and second protruding parts which are arranged on the same conductive pattern at intervals; arranging an optical anti-reflection layer covering the conductive pattern layer on the side, at which the conductive pattern layer is formed, of the transparent substrate, so that the optical anti-reflection layer is arranged on the outer sides of the first protruding part and the second protruding part in a surrounding mode; stripping the first protruding part and the second protruding part to form a via hole exposing the conductive pattern layer; and forming an electrode pattern layer covering the optical anti-reflection layer and filling the via hole, wherein the electrode pattern layer realizes bridging connection through a conductive pattern exposed at the via hole. According to the invention, the preparation process of the touch panel is simplified, the preparation efficiency of the touch panel is improved, and the preparation cost is saved.

Description

technical field [0001] The invention relates to the technical field of touch control, in particular to a touch panel and a preparation method thereof, a touch display screen and electronic equipment. Background technique [0002] In the related art, the SITO process is used to prepare the touch panel, that is, the electrode layer is formed on one side of the transparent substrate by bridging, and the formed electrode layer includes criss-crossing transmitting electrode strips (referred to as TX electrodes) and receiving electrode strips ( referred to as the RX electrode). In the process of preparing a touch panel using the SITO process, it is necessary to plate a conductive layer (such as an ITO layer or a copper layer) on a transparent substrate, and then perform a first yellow light process on it to form multiple array rows. Cloth and use the conductive pattern for subsequent bridging, and then use the second yellow light process to form a bridging layer on the conductive...
