Embodiment Construction

[0034] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present invention, but should not be understood as limiting the present invention.

[0035] In one aspect of the present invention, the present invention provides a method of manufacturing an organic light-emitting display substrate. In this method, the cavity length adjustment layer can be easily formed by setting the conductive ink on the substrate, and by controlling the parameters in the process of setting the conductive ink, etc., the cavity length adjustment layer provided in the sub-pixel regions of different colors can be easily controlled. Thickness (for example, the cavity length ad...

Abstract

The invention discloses an organic light-emitting display substrate, a manufacturing method thereof and a display device. Specifically, the invention provides a method for manufacturing an organic light-emitting display substrate, and comprises the following steps: providing a substrate, a pixel definition layer being arranged on the substrate and defining a plurality of sub-pixel regions of different colors; and arranging conductive ink in the plurality of the sub-pixel regions to form a cavity length adjusting layer, the thickness of the cavity length adjusting layer being different in the sub-pixel regions of different colors. Thus, the method can easily and conveniently form the cavity length adjusting layers of different thicknesses in the sub-pixel regions of different colors, thereby improving the color purity of the organic light-emitting display panel and further improving the display quality of the organic light-emitting display panel.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular, to an organic light-emitting display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic electroluminescence (OLED) display technology is due to its self-luminescence, wide viewing angle, high contrast, low power consumption, extremely high response speed, ultra-lightweight and thin, soft display, rollable screen, strong temperature adaptability, simple manufacturing process, etc. The advantages have become a research hotspot in the field of optoelectronic display technology. Display full-color is an important sign to test whether the display is competitive in the market. Therefore, many full-color technologies have also been applied to OLED displays. According to the type of panel, there are usually the following three types: pixel independent light emission (such as red, green and blue (RGB) )), Color Conversion and Color Fi...
