Touch panel, preparation method and display device

Abstract

The invention discloses a touch panel, a preparation method and a display device. The preparation method of the touch panel comprises the steps: forming a first structural layer and a second structural layer which are sequentially away from a substrate on the substrate; forming a first channel opening, a middle channel and a second channel opening which are communicated in sequence in the first structural layer and the second structural layer; forming a middle channel in the first structure layer; forming a first channel opening and a second channel opening in the second structure layer, and forming a bridge-shaped structure between the first channel opening and the second channel opening; depositing a conducting layer on the second structure layer, and forming first electrodes and second electrodes which are insulated from each other on the conducting layer, the conducting layer located on the side, away from the substrate, of the bridge-shaped structure forms a first connecting part, and the adjacent first electrodes are electrically connected through the first connecting part, and the adjacent second electrodes are electrically connected through a second connecting part formed by the conductive layer infiltrated into the middle channel. According to the technical scheme provided by the invention, the touch panel which is simple in process and high in production efficiency can be realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch panel, a manufacturing method, and a display device. Background technique [0002] In recent years, touch technology has been more and more widely used on display devices of various sizes. As a new type of human-computer interaction input display panel, the touch display panel is different from the traditional display, keyboard and mouse input methods. Compared with the touch screen, the input is simpler, more direct and more convenient. [0003] In order to realize the touch function of the display device, it is usually necessary to introduce touch electrodes into the display device. Different touch electrodes are insulated from each other, and bridges need to be provided between adjacent touch electrodes for connection. Due to the limitation of the process, in practice In the preparation process, multiple metal depositions, photolithography, and etching are required t...

[0003] In order to realize the touch function of the display device, it is usually necessary to introduce touch electrodes into the display device. Different touch electrodes are insulated from each other, and bridges need to be provided between adjacent touch electrodes for connection. Due to the limitation of the process, in practice In the preparation process, multiple metal depositions, photolithography, and etching are required to achieve it, the production cycle is long, the process is complicated, and the production efficiency is low.
