Abstract

The embodiments of the invention disclose an OLED substrate, a manufacturing method, and a display device, relate to the field of display technology, and are used to solve the OLED color shift problem in the OLED display device. The OLED substrate includes a base substrate, patterned metal wiring is formed on the surface of the base substrate, and a flatness adjustment layer is formed on the surface of the base substrate not covered by the metal wiring; the flatness A planarization layer is formed on the surface of the degree adjustment layer facing away from the base substrate and the surface of the metal wiring facing away from the base substrate, and an OLED is formed on the surface of the planarization layer facing away from the base substrate anode. The metal wiring and the flatness adjustment layer are respectively formed through the same mask. The OLED substrate provided by the embodiment of the present invention is used for AMOLED display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED substrate, a manufacturing method, and a display device. Background technique [0002] Active-matrix organic light emitting diode (AMOLED) panels are widely used in the display field due to their advantages of high brightness, full viewing angle, fast response speed, and flexible display. [0003] At present, in the process of making small-sized AMOLED panels, the Fine Metal Mask (FFM) process is mostly used to make the metal traces on the Low Temperature Poly-Silicon (LTPS) backplane of the AMOLED panel. Wire. However, after long-term use of the AMOLED panel produced by the FFM process, the image displayed by the AMOLED panel is particularly prone to color shift, such as reddish display image, resulting in poor display effect of the AMOLED panel. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an OLED substrat...
