Problems solved by technology

[0003] However, in the existing device structure, due to the microcavity effect of the printed color film substrate, the light extraction rate is reduced, and the photons generated in the quantum dot color film substrate layer are totally reflected in the interface layer due to the optical waveguide effect, and some photons are restricted. In the color filter substrate layer, energy loss is caused, which affects the display effect of the display panel

Abstract

The embodiment of the invention discloses a quantum dot display panel and a preparation method thereof. The quantum dot display panel comprises an array substrate; a light-emitting layer arranged on the array substrate and used for providing a light source; the packaging layer arranged on the light-emitting layer and used for packaging the light-emitting layer to prevent the light-emitting layer from being eroded by water vapor; and a color filter layer arranged on the packaging layer, wherein the color filter layer comprises a plurality of pixel areas, each pixel area comprising a plurality of sub-pixel filter layers, the sub-pixel filter layers being made of quantum dot materials, and light generated after the quantum dot materials are excited being the same as the sub-pixel filter layers in color. A concave surface structure is formed on the upper surface of at least one sub-pixel filter layer. According to the quantum dot display panel provided by the embodiment of the invention, the light extraction rate of the quantum dot display panel is improved, and the display effect of the quantum dot display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot display panel and a preparation method thereof. Background technique [0002] Quantum Dot Light Emitting Diodes (QLED) are recognized by the industry as the display device with the most development potential because of its advantages such as high brightness, wide color gamut, long life, and high internal quantum efficiency. In particular, the use of quantum dots to print color filter substrates (Color Filter, CF) can replace polarizers, which greatly improves the light extraction rate, and at the same time greatly reduces the process cost, which has become the main direction of future display research. [0003] However, in the existing device structure, due to the microcavity effect of the printed color film substrate, the light extraction rate is reduced, and the photons generated in the quantum dot color film substrate layer are totally reflected in the interface...
