Abstract

The invention discloses an organic light emitting diode (OLED) display panel, a manufacturing method of the OLED display panel and a display device. The process step is simplified, the yield is improved, and the display efficiency is improved. The OLED display panel comprises a cover plate, a back panel and a transparent electrode layer, wherein the cover plate and the back panel are buckled, a plurality of color film units are arranged on the cover plate in an array way, gaps among the color film units are filled with auxiliary negative electrodes, each auxiliary negative electrode comprisesa black matrix, a buffer layer and a metal layer which are sequentially formed on the cover plate, a flat layer is formed on the auxiliary negative electrodes and the color film units, a plurality ofholes are formed in positions, corresponding to the auxiliary negative electrodes, of the flat layer, a plurality of cushion pads are formed at positions, corresponding to the auxiliary negative electrodes, of the flat layer and are arranged between the cover plate and the back panel in a prop-against way, the transparent electrode layer is formed on the flat layer and the cushion pads, penetratethrough at least one part of holes and communicate with the auxiliary negative electrodes, and a color film layer of the cover and a pixel region of the back panel are arranged opposite to each other.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, a method for manufacturing the OLED display panel, and a display device. Background technique [0002] Due to its thinness, lightness, wide viewing angle, active luminescence, continuously adjustable luminous color, low cost, fast response, low energy consumption, low driving voltage, wide operating temperature range, simple production process, high luminous efficiency and Flexible display and other advantages have been listed as a promising next-generation display technology. [0003] In order to realize the manufacture of high-pixel display screens and obtain high-definition and high-fidelity display images, the industry has proposed a scheme of combining Oxide BP with printed OLEDs to achieve top emission. The inventors found that because the top emission needs to cooperate with the p...
