Abstract

The invention discloses a touch control display device, a manufacturing method thereof and electronic equipment. When the touch control display device is manufactured, a via hole enabling a connecting electrode to be connected with a touch control electrode and a common electrode and a via hole enabling a pixel electrode to be connected with a data line metal layer can be formed through one photolithographic process. Manufacturing technology is simple, technological error is small, production period is short, production cost is low, and production efficiency is improved greatly.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display device, a method for preparing the touch display device and electronic equipment with the touch display device. Background technique [0002] With the development of touch technology, full in-cell touch (Full In-Cell Touch) display devices are more and more widely used. The fully embedded touch display device in the current technology includes a thin film transistor (TFT, Thin Film Transistor), a flat layer (PLN layer), a common electrode, an interface layer (IL layer), a touch electrode, a protective layer, and pixels arranged in sequence. electrode. Specifically, the touch electrodes are connected to the common electrodes through via holes opened on the interface layer. The pixel electrode is sequentially connected to the data line metal layer of the thin film transistor through via hole 2 formed on the protection layer, via hole 3 formed on the inter...
