Abstract

The present application discloses a display substrate, a preparation method thereof, and a display device. The display substrate includes: a base substrate, a light-emitting structure layer disposed on the base substrate, and a light-emitting structure layer disposed on the light-emitting side of the light-emitting structure layer includes: The color thin film layer of a plurality of sub-pixels, the pinhole thin film structure layer arranged on the light-emitting side of the color thin film layer, the pinhole thin film structure layer includes a plurality of enlarged structures, and the enlarged structures correspond to the sub-pixels one by one , and the orthographic projection of the magnifying structure on the base substrate is located inside the orthographic projection of its corresponding sub-pixel on the base substrate, and the magnifying structure is used to perform an image of its corresponding sub-pixel enlarge. In the solution provided by this embodiment, the zoom-in structure enlarges the images of the sub-pixels to obtain a virtual image and then outputs and displays it, which eliminates the gap between images of adjacent sub-pixels and reduces or eliminates the screen door effect.

Description

technical field [0001] The invention relates to display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Silicon-based OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) is a new type of OLED display device with a silicon substrate as a substrate. Silicon-based OLED has the characteristics of high PPI (Pixels Per Inch, pixel density), small size, and high contrast. Source addressing, with TCON (logic board), OTP (OneTime Programmable, one-time programmable) and other circuits to achieve lightweight. Silicon-based OLEDs are widely used in the fields of near-eye display, virtual reality, and augmented reality, especially in AR (Augmented Reality, augmented reality) / VR (Virtual reality, virtual reality) head-mounted display devices. With the development of big data and information interaction technology, the application of virtual reality technology is widely popularized. VR tec...
