Embodiment Construction

[0058] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0059] The light-emitting layer in the OLED display panel is usually composed of electroluminescent (English: electroluminescent) materials. Currently, the method of manufacturing the light-emitting layer in the OLED display panel can include two types: vacuum evaporation and solution process. The solution process can include spin coating technology, inkjet printing technology and nozzle coating technology. Among them, the solution of electroluminescent material can be sprayed onto the area where the luminescent layer is to be formed by inkjet printing technology. After the solution is dried and solidified, a luminescent layer capable of emitting light of different colors can be formed. The uniformity of the luminescent layer determines the ...

Abstract

The invention discloses an organic light-emitting diode display panel and a manufacturing method thereof and a display device, and belongs to the technical field of display. The OLED display panel comprises a substrate and at least two light-emitting units arranged on the substrate. The areas of light-emitting layers in any two light-emitting units are close, so as to ensure that the light-emitting layer in each light-emitting unit has a similar volatilization speed. By virtue of the display panel, the problems in the related art are solved as follows: due to the fact that the volatilization speeds of the different light-emitting layers are different, consequently, the uniformity of the light-emitting layers in the light-emitting units used for emitting different colored lights is poor, and the uniformity of light rays emitted by the light-emitting units used for emitting different colored lights is poor. The uniformity of the light-emitting layers in the light-emitting units of different colored lights is improved, and the uniformity of light rays emitted by the light-emitting units of different colored lights is also improved.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to an organic light emitting diode display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display panel is a self-luminous display panel, which has the advantages of fast response, wide viewing angle, high brightness, bright colors, lightness and thinness. [0003] The OLED display panel in the related art includes a plurality of light-emitting units arranged on a base substrate, and each light-emitting unit includes two electrodes and a light-emitting layer arranged between the two electrodes. The overlapping area of ​​the orthographic projection of the two electrodes on the base substrate coincides with the orthographic projection of the light-emitting layer on the base substrate to drive the light-emitting layer to emit light. According to th...
