Abstract

The invention provides an IPS-type In Cell touch display panel and a manufacturing method. The IPS-type In Cell touch display panel is provided with an insulating light resistance block (6) for insulation at the cross position of a touch transmitting electrode (4) and a touch receiving electrode (5). According to the method, a gray-scale mask etching process is adopted to manufacture the touch transmitting electrode (4), organic light resistance correspondingly located at the cross position of the touch transmitting electrode (4) and the touch receiving electrode (5) is retained to manufacture the insulating light resistance block (6), and the touch transmitting electrode (4) and the touch receiving electrode (5) are insulated through the insulating light resistance block (6). A film-coating and mask etching process special for manufacturing an insulation layer is omitted, accordingly a manufacturing process of the touch display panel is simplified, manufacturing cost is reduced, and production efficiency is improved. In addition, the touch transmitting electrode (4) and the touch receiving electrode (5) can further play an electromagnetic shielding role on a liquid crystal layer capacitor, and a specially-manufactured protection electrode is not needed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an IPS type In Cell touch display panel and a manufacturing method thereof. Background technique [0002] With the rapid development of display technology, touch display panels have been widely accepted and used by people, for example, smart phones, tablet computers, etc. all use touch display panels. The touch display panel adopts embedded touch technology to integrate the touch panel and the liquid crystal display panel, and embeds the function of the touch panel into the liquid crystal display panel, so that the liquid crystal display panel has the functions of displaying and sensing touch input at the same time. [0003] A liquid crystal display panel is usually composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged ...
