Problems solved by technology

In the field of handheld display, such as mobile phones, tablets, etc., the overall touch display is developing towards thinner and thinner. The distance between the display layer and the display layer is getting closer, which leads to the continuous increase of touch noise, the continuous decrease of touch signal volume, and the continuous decrease of touch accuracy.

Abstract

The invention discloses a touch panel, a manufacturing method thereof, a touch screen and a display device. The touch panel comprises a touch electrode layer with a plurality of matrix-arranged touch units, each touch unit comprises a touch driving electrode and a touch sensing electrode which are complementary in shape, the touch sensing electrodes of two adjacent touch units are connected, the touch driving electrodes of the two adjacent touch units are connected, complementary edges of the touch driving electrode and the touch sensing electrode of each touch unit have curve changes, so that the interaction area of the touch driving electrodes and the touch sensing electrodes is increased, touch sensing signal quantity can be increased, and touch sensitivity is improved. Moreover, the edges of the touch driving electrodes and the touch sensing electrodes have circular arc chamfers by the design of the curve change edges, charge accumulation in the electrodes can be decreased, and uniformity of touch performances is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch panel, a manufacturing method thereof, a touch screen and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panel) have gradually spread in people's lives, and the corresponding touch panel market size is also increasing. , reduce production costs, improve performance as the goal, and continuously improve the production technology level of touch panels. [0003] In the field of touch display, there are many ways to set up touch screens, including: monolithic (OGS, Oneglasssolution), external (On Cell), embedded (In Cell) and other touch structures, wherein the On Cell structure is based on It is favored for its high touch precision and the advantages of being easy to manufacture in organic light-emitting displays. At present, On Cell technology is mainly divided into two categories: singl...
