Problems solved by technology

[0003] For organic light emitting diode display panels, due to the high resistance of the top transmissive electrode, there will be an obvious voltage drop (IR drop) on the top transmissive electrode, and the brightness uniformity of the organic light emitting diode display panel is poor.

Embodiment Construction

[0055] In order for those skilled in the art to better understand the technical solution of the present disclosure, the display substrate provided by the present disclosure, its manufacturing method, and the display panel are described in detail below with reference to the accompanying drawings.

[0056] In this disclosure, the two structures "set in the same layer" means that the two structures are patterned and formed by the same material layer, so they are in the same layer in the layered relationship, but it does not mean that the distance between them and the substrate is equal , does not mean that they are exactly the same as other layer structures between the substrates.

Abstract

The invention discloses display substrates. A display substrate comprises a substratum substrate, wherein a first electrode, a first auxiliary electrode and a boss are set at one side of the substratum substrate. An orthographic projection of a surface of a side of the boss opposite to the substratum substrate on the substratum substrate is completely overlapped with the orthographic projection ofthe boss on the substratum substrate. The first auxiliary electrode comprises a first conductive connection part attaching to a preset area on a side face of the boss. A pixel definition layer is setat the side of the first electrode opposite to the substratum substrate. A pixel storage hole and a slot are set in the pixel definition layer. The pixel storage hole is communicated with the first electrode. The slot is communicated with the first conductive connection part. An organic function layer is set at the side of the pixel definition layer opposite to the substratum substrate. The organic function layer is electrically connected with the first electrode through utilization of the pixel storage hole. The organic function layer is a hollow structure in the preset area. A second electrode is set at the side of the organic function layer opposite toe the substratum substrate. The second electrode is electrically connected with the first conductive connection part through utilizationof the hollow structure. The second electrode is connected with the first auxiliary electrode in parallel.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display panel. Background technique [0002] In an organic light emitting diode (Organic Light Emitting Diode, OLED for short) adopting a top emission structure, the light transmittance of the top transmission electrode directly determines the light extraction efficiency of the organic light emitting diode. In order to ensure the light transmittance of the top transmissive electrode, the top transmissive electrode is often made very thin, but at this time the resistance of the top transmissive electrode will be very large. [0003] For the organic light emitting diode display panel, since the resistance of the top transmissive electrode is relatively large, there will be an obvious voltage drop (IR Drop) on the top transmissive electrode, and the brightness uniformity of the organic light emitting diode display ...
