Abstract

The invention discloses an organic electroluminescent display panel and a preparation method thereof and a display device. The organic electroluminescent display panel includes a substrate, a pixel limitation layer, a multi-hole membrane, an organic function layer and a cathode layer, wherein the pixel limitation layer is located on the substrate, the multi-hole membrane is located on patterns of the pixel limitation layer, the organic function layer is located on areas outside the patterns of the pixel limitation layer, and the cathode layer is located on the multi-hole membrane and on the organic function layer; the multi-hole membrane is filled with a liquid conductive material, and the cathode layer is connected with the liquid conductive material in the multi-hole membrane. According to the organic electroluminescent display panel, by arranging the multi-hole membrane which is filled with the liquid conductive material on the patterns of the pixel limitation layer, the cathode layer is connected with the liquid conductive material, the thickness of a conductive membrane layer at positions corresponding to the patterns of the pixel limitation layer is increased, the sheet resistance of the cathode layer is reduced, the luminance uniformity of the display panel is improved, the multi-hole membrane does not occupy the area of display areas, and the normal display of display panel cannot be influenced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence display panel, a manufacturing method thereof and a display device. Background technique [0002] In the field of display, compared with Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED) has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, light and thin, etc. It is considered to be the next generation display technology. OLED devices have two light emitting methods: bottom emission and top emission. Compared with top emission OLED devices, top emission OLED devices have better resolution and color saturation, and have high luminous efficiency, wide color gamut and long life. The manufacturing process of the device is also relatively difficult. [0003] The cathode fabrication of top-emitting OLED devices has a crucial impact on the performance of OLED devices. The cathode film...
