Problems solved by technology

[0002] Based on the existing display products, especially the mobile phone display to achieve the naked-eye 3D display effect, there are defects such as low PPI (pixel density), less information, and a small 3D viewing angle, which can easily cause dizziness and poor user experience.
In order to solve these problems, the pixel density of display products can be increased to achieve high-resolution naked-eye 3D display. However, the existing OLED display substrates pattern the anode through a patterning process. Due to the limitation of the precision of the patterning process, the PPI of the OLED display substrate hard to improve

Embodiment Construction

[0039] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0040] Glasses-free 3D display technology mainly includes holographic 3D display technology, autostereoscopic 3D display technology, etc. Among them, autostereoscopic 3D display technology has been considered as the naked-eye 3D display technology that may be commercialized the fastest because it can obtain dynamic, colorful and three-dimensional display effects with a large viewing angle. Autostereoscopic 3D display technology can be roughly divided into two categories: one is naked-eye 3D display technology based on geometric optics, such as the relatively mature cylindrical lens array technology, parallax barrier technology, and microlens array technology. This type of technology is mainly based on the principles of straight line pr...

Abstract

The invention provides an OLED display substrate, a manufacturing method thereof and a display device, and belongs to the technical field of display. The manufacturing method of the OLED display substrate comprises: before an anode of the OLED display substrate is formed, a plurality of barrier walls are formed in a pixel area of the OLED display substrate through a nanoimprint lithography process, and each pixel area is divided into a plurality of sub-pixel areas through the barrier walls; forming an anode material layer covering the barrier wall; and removing a part, far away from the substrate of the OLED display substrate, of the anode material layer, exposing the barrier walls, and dividing the anode material layer into a plurality of anode patterns by the barrier walls, wherein eachanode pattern is located in one sub-pixel region. According to the technical scheme, the pixel density of the OLED display substrate can be improved, and then the naked eye 3D display effect can be achieved based on the OLED display substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Based on existing display products, especially mobile phone display screens to achieve naked-eye 3D display effects, there are defects such as low PPI (pixel density), less information, and small 3D viewing angles, which can easily cause dizziness and poor user experience. In order to solve these problems, the pixel density of display products can be increased to achieve high-resolution naked-eye 3D display. However, the existing OLED display substrates pattern the anode through a patterning process. Due to the limitation of the precision of the patterning process, the PPI of the OLED display substrate It is difficult to improve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an OLED display substrate, its...
