Display panel, driving method thereof and display device

Abstract

The invention provides a display panel, a driving method thereof and a display device. The display panel comprises a substrate, a plurality of light-emitting units arranged on the substrate in an array mode, and a blocking structure; any light-emitting unit in the plurality of light-emitting units comprises an anode, a cathode and a light-emitting functional layer arranged between the anode and the cathode; a preset distance is reserved between every two adjacent anodes; the blocking structure is arranged between the light-emitting function layers and the substrate and is located between at least part of the two adjacent anodes; the orthographic projection of the blocking structure on the substrate and the orthographic projection of the anodes on the substrate are not overlapped with eachother; the blocking structure receives an electric signal to generate an electric field perpendicular to the direction of a plane where the substrate is located. With the display panel, the driving method thereof and the display device adopted, the technical problem of transverse crosstalk is solved, and the display effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Display, OLED) display panels have been widely valued due to their advantages such as self-illumination, fast response, wide viewing angle, high brightness, bright colors, and thinness. [0003] For silicon-based OLED display panels, white organic light-emitting units and color filter layers are usually used to realize the light emission of red pixels, green pixels and blue pixels. 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...

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
