Abstract

The invention discloses a color conversion layer and a manufacturing method thereof and a display panel. A color conversion layer is applied in a display panel with a straight down surface light source, and the color conversion layer comprises a quantum dot film and a functional film. The functional film is arranged on the side, facing the surface light source, of the quantum dot thin film, lightwave emitted by the surface light source enters the quantum dot thin film through the functional film, and the light wave excited by the quantum dot thin film is reflected back to the quantum dot thinfilm through the functional film, the absorption loss of a substrate reflector is reduced, and the optical efficiency of the straight down surface light source is improved.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a color conversion layer, a manufacturing method thereof, and a display panel. Background technique [0002] With the development of science and technology, people's living standards have been significantly improved, and new technology products are being updated faster and faster. Only from the analysis of display products, from the earliest CRT (Cathode Ray Tube) to LCD (Liquid Crystal Display), the current development to OLED (Organic Light Emitting Display), QLED (Quantum Dot Light Emitting Diodes), mini-LED. The future Micro-LED display technology has also been proposed, and some major domestic and foreign manufacturers are making plans in this regard. Various head-mounted displays adapted to AR / VR have also sprung up like mushrooms after rain. [0003] The current mainstream display technologies are LCD and OLED displays, but both have their own advantages and disad...
