Abstract

A method of manufacturing a touch control display device includes the following steps: forming a sensing element on a substrate, and forming a sensing signal line electrically connected with the sensing element; the step of forming the sensing element includes: forming a semiconductor layer on the substrate, the semiconductor layer including a semiconductor pattern of the sensing element; forming a gate insulating layer on the semiconductor layer; forming a first conductor layer on the gate insulating layer; forming an interlaye insulating layer on the gate insulating layer; performing a tempering process; after the tempering process, removing the interlayer insulating layer in a gate predetermined region; removing the first conductor layer in the gate predetermined region; forming a gate in the gate predetermined region; and forming a second conductor layer, wherein the second conductor layer includes a source electrode and a drain electrode of the sensing element that are electrically connected with the semiconductor pattern of the sensing element.

Description

technical field [0001] The present invention relates to a manufacturing method of a display device, and in particular to a manufacturing method of a touch display device. Background technique [0002] At present, the on-cell display touch technology requires setting touch elements outside the display for touch sensing operation, so as the screen size gradually enlarges, it will face the disadvantages of greatly increasing product yield and manufacturing cost. The embedded (In-cell) optical touch technology can be multi-touch and directly embed the touch sensing element on the array substrate of the liquid crystal display (Liquid Crystal Display, LCD), so that the use of existing production capacity, adjustment The photomask process can be produced without additional investment in huge capital expenditures, so it can reduce the cost of lamination and assembly, and reduce the thickness and weight of the device. It has the advantages of high yield, low cost, and no size limit. ...
