Abstract

The present invention provides a display panel, which includes a substrate, a cathode layer, a first gap is formed on the cathode layer, a touch function layer, at least one touch function layer is not arranged on the side of the cathode layer away from the substrate, and the touch function layer is formed There is a touch component, and adjacent touch components located on the same touch function layer form a second gap, wherein the second gap and the first gap meet a preset condition and make the touch component form a touch function unit; in this structure Among them, based on the first gap formed on the cathode layer, after the finger touches the screen, the generated electric field lines are not shielded by the cathode layer and can penetrate into the structure under the cathode, so that the touch function layer can be completely or partially not provided In the direction where the cathode layer is away from the backplane, the technical problem that the touch structure of the existing display panel can only be realized by the On Cell method is solved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel. Background technique [0002] In the AMOLED display panel structure, the existing touch control structure is implemented in the On Cell method, that is, all the touch function layers are attached to the cathode layer (Cathode) on the top of the OLED in the direction away from the backplane. This is because the Cathode Manufactured by the Common Mask evaporation process, the structure is integral. After the finger touches the screen, the electric field lines generated are shielded by the Cathode layer and cannot penetrate the structure under the Cathode. [0003] That is to say, there is a technical problem that the touch structure of the existing display panel can only be realized by the On Cell method. Contents of the invention [0004] The present invention provides a display panel to solve the technical problem that the touch control structure of the existing di...
