Problems solved by technology

[0004] However, in the research, the inventors found that there is a kind of problem in this technology: in the color pixel array with special arrangement, the monochromatic sub-pixel arrangement of RGB pixel unit is actually not uniform
But in displays with RGB pixels, applying a scattering layer will encounter a serious problem: scattering will cause the light of the sub-

Abstract

The invention relates to a display device, a preparation method thereof and a display device. The display device comprises a TFT array substrate; a light-emitting structure which is arranged on the TFT array substrate and comprises a pixel bank, a pixel isolation column and a plurality of pixel units, wherein the height of the pixel bank is larger than that of the pixel isolation column, the pixelbank defines a plurality of pixel grooves in the TFT array substrate, the pixel isolation columns are located in the pixel grooves and divide the pixel grooves into at least two sub-pixel grooves, asub-pixel is formed in each sub-pixel groove, and the colors of the sub-pixels located in the same pixel groove are the same; a scattering layer which is arranged on the light-emitting side of the light-emitting structure and comprises a first black isolation wall and a plurality of scattering units separated by the first black isolation wall, wherein the scattering units and the pixel units are arranged in a one-to-one correspondence mode, and the first black isolation wall and the pixel isolation columns are arranged in a one-to-one correspondence mode. The display device can improve the light extraction efficiency and improve the display effect of a high-resolution display.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a display device, a manufacturing method thereof, and a display device. Background technique [0002] In AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode), QLED (Quantum dot light emitting diodes, quantum dot light-emitting diode) display technology, the top-emitting device structure does not hinder light output due to the driving circuit, so It is beneficial to achieve a higher aperture ratio and improve the display effect. In this technology, because the electrode on the light-emitting side often has the characteristic of reflecting visible light, the device often has a strong optical microcavity effect. Under the optical micro-cavity effect, the light output from the front is enhanced, but the light output from the side angle is correspondingly weakened. Such as figure 1 Shown is a schematic structural diagram of a common top-e...
