Abstract

The invention provides a display panel and a display device. The display panel comprises a pixel definition layer, a through hole, a first organic layer, a first isolation column, a second isolation column and a second organic layer. The display panel and the display device have the technical effects that the equivalent included angle between the isolation column and the organic layer is improved,the isolation effect on the organic layer is enhanced, the conductivity between the cathode layer and the auxiliary cathode is further improved, the voltage drop of the display panel can be reduced,and the brightness uniformity of the display device is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] In large-size AMOLED panels, the light emitting mode is divided into two kinds of light emitting schemes: top emission and bottom emission, among which top emission has the advantage of high aperture ratio. In view of the short lifespan of OLED devices at present, a high aperture ratio can alleviate the display degradation caused by the lifespan of the device. However, since the top-emission solution requires the light emitted by the OLED device to pass through the cathode, the thickness of the cathode needs to be made very thin to ensure the light transmittance. This requirement makes the sheet resistance of the cathode very large. A large surface resistance will cause inconsistent voltage drops at different positions, which will eventually affect the current of the OLED device and the display uniformity of the panel. [...
