Problems solved by technology

[0005] Since at least one patterning process is required to form the above-mentioned touch electrodes, compared with a liquid crystal display panel without a touch function, when it is added with a touch function, it will inevitably lead to an increase in the number of patterning processes in the production process, thereby making its production cost Increase

Abstract

The embodiment of the invention provides an upper substrate for the touch display panel, and a preparation method thereof, a touch display panel and a preparation method thereof, relating to the technical field of display and aiming at preventing the increase of picture composition times, and lowering the production cost. The preparation method of the upper substrate comprises the following steps: forming a black matrix through one-time composition technology, wherein the black matrix in the display area corresponds to a gap between the two adjacent touch electrodes; forming a negative photosensitive type organic resin thin film on the substrate of the black matrix, exposing and developing by taking the black matrix as a mask, removing the organic resin thin film corresponding to the black matrix so as to form an organic resin layer; forming a transparent conductive thin film above the organic resin layer, wherein the transparent conductive thin films respectively positioned above the organic resin layer and the black matrix are separated, the touch electrode is formed on the transparent conductive thin film above the organic resin layer, and a retention pattern is formed on the transparent conductive thin film above the black matrix. The preparation methods are used for manufacturing the upper substrate for the touch display panel, and the touch display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an upper substrate for a touch display panel and a preparation method, a touch display panel and a preparation method. Background technique [0002] With the rapid development of display technology, the birth of a touch panel (TP for short) makes people's lives more convenient. [0003] Taking a liquid crystal touch display panel as an example, it includes an array substrate and a color filter substrate, wherein the touch electrodes for realizing the touch function may be located on the color filter substrate. [0004] For example, taking a plug-in liquid crystal touch display panel as an example, a black matrix needs to be formed on the color filter substrate through a patterning process. A transparent touch electrode is formed. [0005] Since at least one patterning process is required to form the above-mentioned touch electrodes, compared with a liquid crystal display panel...
