Embodiment Construction

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0043] The inventors realized that chemical vapor deposition (CVD) or plasma sputtering (sputter) is commonly used to prepare the anode of organic light-emitting display substrates. The above-mentioned methods have high requirements on process conditions and high production costs, and, In the above method, the deposited or sputtered anode material (such as indium tin oxide, ITO) is free to diffuse, so the thickness of the anode layer prepared by the above method is the same, that is, after one preparation process, the deposition or sputte...

Abstract

The invention discloses an organic light-emitting display substrate, a manufacturing method thereof, and a display device. Specifically, the present invention proposes a method for manufacturing an organic light-emitting display substrate, including: providing a substrate, on which a pixel defining layer is disposed, and the pixel defining layer defines a plurality of sub-pixel regions; printing an ink containing a solvent and a first anode material above the bottom; and drying the printed ink to form a first anode layer based on the pixel defining layer. Therefore, the method can easily form the first anode layer by inkjet printing, and improves the display quality and performance of the prepared organic light-emitting display substrate.

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 characterized by self-illumination, wide viewing angle, high contrast ratio, low power consumption, extremely high response speed, ultra-thin weight, flexible display, rollable screen, strong temperature adaptability, and simple manufacturing process, etc. Advantages, has become a research hotspot in the field of optoelectronic display technology. In recent years, with the continuous improvement of manufacturing technology and technology, flexible organic electroluminescent display (flexible OLED) technology has also been vigorously developed. For example, many smart phones and smart watches have adopted flexible OLED technology. The display quality of the organic light emitting display...
