Embodiment Construction

[0044] An embodiment of the present invention provides a display panel, including: a substrate; a pixel defining layer located on one side of the substrate, with an opening in the pixel defining layer; an OLED backlight structure layer located in the opening; The quantum dot layer on the substrate side. The display panel has a larger area of ​​the light-emitting surface of the quantum dot layer, thereby having higher luminous efficiency and lower power consumption.

[0045] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] In the description of the present i...

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises a substrate, a pixel limiting layer which is located on one side of the substrate, and is provided with an opening, an OLED backlight structure layer located in the opening, and a quantum dot layer which is positioned in the opening and is positioned on one side, opposite to the substrate, of the OLED backlight structure layer. The display panel is high in integration level, and miniaturization and thinning of the display panel are facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, referred to as OLED) display, also known as organic electroluminescent display, is a new type of flat-panel display. A series of advantages such as light, ultra-thin, high brightness, low power consumption and fast response, and the response speed can reach 1000 times that of liquid crystal displays. Therefore, OLED displays have become very popular flat-panel display products at home and abroad, and have broad application prospects. . [0003] The structure of the OLED display includes a substrate glass, an anode stacked on the substrate glass, an organic functional layer, a cathode, and a cover plate packaged on the glass substrate. Quantum dot (quantum dot, QD) materials have the advantages of high luminous ...
