Problems solved by technology

[0004] The quantum dot phototransition film in the QD-OLED display panel is conducive to improving the color gamut of the display panel. However, with the continuous development of display technology, people have higher and higher requirements for the display quality of the display panel. The current QD- The OLED display panel cannot meet the future market demand, therefore, it is necessary to develop a new display panel to further improve the color gamut of the display panel, thereby further improving the display quality to meet the market demand

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a transparent substrate, a color filter and a quantum dot color conversion structure, wherein the color filter and the quantum dot color conversion structure are sequentially arranged on the transparent substrate; the quantum dot color conversion structure comprises a resonant cavity definitionlayer and a quantum dot color conversion layer which are sequentially arranged on the side, which is away from the transparent substrate, of the color filter; a plurality of reflective resonant cavities which are periodically distributed are formed on the resonant cavity definition layer, and the quantum dot color conversion layer is at least arranged in part of the reflective resonant cavities and is in contact with the color filter. The reflective resonant cavity can narrow the emission spectrum of the quantum dots in the quantum dot color conversion layer, so that the display color gamut ofthe display panel is further improved, and the display quality is further improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] The rapid development of OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has promoted the rapid entry of curved surface and flexible display touch products into the market, and technology updates in related fields are also changing with each passing day. [0003] In recent years, quantum dots (Quantum Dots, QDs for short) materials have become the core of a new display technology because of their low cost and excellent optical properties. The QD-OLED display panel combines OLED electroluminescence technology and quantum dot photoluminescence technology, including an OLED array substrate emitting blue light, a quantum dot photoelectric conversion film and a color filter (Color Filter, CF for short). The QD-OLED display panel uses blue light OLED as a l...
