Abstract

The present invention provides a liquid crystal touch display panel, which is provided with via holes on both sides of the opening area of ​​the planarization layer and the metal layer, and a reinforcing layer on the surface of the common electrode; the beneficial effects: compared with the existing liquid crystal touch display Panel, the present invention is provided with via holes on both sides of the opening area, and the wire exchange layer of the common electrode in the opening area is relatively gently bent and has less stress, which can effectively avoid fluctuations in the manufacturing process, eliminate the incision, and solve the problem that the common electrode is thin and easy to use. At the same time, a reinforcing layer is added on the surface of the wire exchange layer to increase the film thickness of the common electrode layer in the opening area, so as to further avoid the common electrode breakage and effectively improve the yield of the product.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a liquid crystal touch display panel. Background technique [0002] At present, the integrated touch display panel mainly includes two types: the on-cell type in which the touch sensor is arranged between the polarizer of the display panel and the color filter substrate; and the touch sensor embedded in In-Cell in the pixel structure of the display panel. [0003] figure 1 For existing in-cell touch display panels, such as figure 1 As shown, the touch display panel 100 includes an array substrate 101 , a color filter substrate 103 , and a liquid crystal layer 102 located between the array substrate 101 and the color filter substrate 103 . The wiring layer 1012 and the flattening layer 1013 covering the metal wiring layer 1012. The flattening layer 1013 includes the flattening layer 10141 and the flattening layer 10142. Due to the fluctuation, the process of open...
