Quantum dot display substrate, manufacturing method thereof, and quantum dot display device

Abstract

The invention discloses a quantum dot display substrate, a manufacturing method thereof and a quantum dot display device. The quantum dot display substrate includes a black matrix pattern and a quantum dot pattern, the quantum dot pattern is located between the black matrix patterns, and the quantum dot display substrate also includes: a first substrate substrate and a substrate located on the first substrate A first optical layer and a second optical layer on one side of the substrate, the first optical layer is located on a side of the second optical layer away from the first base substrate; the first optical layer is used for The incident light is collimated to form collimated light, and the collimated light is output to the second optical layer; the second optical layer is used to adjust the light emitting direction of the collimated light to form outgoing light, and the outgoing light irradiates to the black matrix pattern. The invention prevents the emitted light from being irradiated on the quantum dot pattern, thereby enabling the quantum dot display device to perform real dark state display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot display substrate, a manufacturing method thereof, and a quantum dot display device. Background technique [0002] With the development of thin film field effect transistor liquid crystal display (TFT-LCD Display) technology and the advancement of industrial technology, the production cost of liquid crystal display devices has been reduced and the manufacturing process has been improved day by day. Liquid crystal display devices have replaced cathode ray tube display devices as It is the mainstream technology in the field of flat panel display, and because of its own advantages, it has become an ideal display device in the minds of the market and consumers. [0003] With the development of display technology, quantum dot (Quantum Dot, QD for short) display devices are more and more widely used. The quantum dot display device may include red quantum dot patterns an...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when the quantum dot display device performs dark state (L0) display, when the external natural light irradiates the quantum dot pattern, since the natural light contains blue light, the red quantum dot pattern will scatter red when the blue light passes by. Light, the green quantum dot pattern will scatter green light when blue light passes by, and the scattered red light and green light make the quantum dot display device emit yellow light, so that the quantum dot display device cannot perform real dark state (L0) display
