A display panel, its driving method and display device

Abstract

The present invention provides a display panel, a driving method thereof, and a display device, wherein the display panel includes: a base substrate, and a plurality of light-emitting units arranged in an array on the base substrate; Any one of the light-emitting units includes an anode, a cathode, and a light-emitting functional layer disposed between the anode and the cathode, wherein a preset distance is spaced between two adjacent anodes; the blocking structure is disposed at the between the light-emitting functional layer and the base substrate, and at least partially between two adjacent anodes, wherein the orthographic projection of the blocking structure on the base substrate is the same as the anode on the The orthographic projections on the base substrate do not overlap each other; wherein, the blocking structure receives electrical signals to generate an electric field in a direction perpendicular to the plane of the base substrate. It is used to solve the technical problem of lateral crosstalk and improve the display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a driving method thereof and a display device. Background technique [0002] The organic light emitting diode (Organic Light Emitting Display, OLED) display panel has attracted extensive attention due to its advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, and thinness. [0003] For a silicon-based OLED display panel, a white organic light-emitting unit and a color filter layer are usually used to realize the light emission of red pixels, green pixels and blue pixels. However, in the production process of the white organic light-emitting unit, the internal organic layers, such as the hole injection layer (Hole Injection HIL, HIL), the hole transport layer (Hole Transport Layer, HTL), the electron transport layer (Electron Transport Layer) , ETL)) and the emission layer (Emission Layer, EL), if there...

AI Technical Summary

Problems solved by technology

However, in the manufacturing process of the white organic light-emitting unit, the internal organic layers, such as the hole injection layer (Hole Injection HIL, HIL), the hole transport layer (Hole Transport Layer, HTL), the electron transport layer (Electron Transport Layer) , ETL)) and the light-emitting layer (Emission Layer, EL), if there are more carriers in an organic layer, the carriers will inevitably move laterally along the organic layer, resulting in enhanced lateral conductivity of the organic layer , for example, when there is current in a pixel, the organic layer with strong lateral conductivity conducts carriers to adjacent pixels, thereby affecting the light emission of adjacent pixels

[0004] It can be seen that the prior art has the technical problems of lateral crosstalk and poor display effect of the display panel
