Abstract

The embodiment of the invention provides a quantum dot display panel and a quantum dot display device. The quantum dot display panel comprises a backlight module composed of an ultraviolet light backlight module and a white light backlight module, a quantum dot color film structure and a white light transmitting area located on the light emitting side of the backlight module. The quantum dot color film structure covers the ultraviolet backlight module, and the white light transmitting area covers the white light backlight module; the vertical projections of a plurality of red light quantum dot substructures of the red light quantum dot color film structure, a plurality of green light quantum dot substructures of the green light quantum dot color film structure, a plurality of blue light quantum dot substructures of the blue light quantum dot color film structure and a plurality of white light transmitting sub areas of the white light transmitting area on the plane where the backlight module is located are not overlapped. According to the technical scheme provided by the embodiment of the invention, the use of a color filter is avoided, and the light emitting efficiency is improved; the quantum dot performance is optimized, and the reliability of the color film structure is ensured; the display brightness can be enhanced directly through the white light transmitting area, and maximum utilization of backlight source energy is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of quantum dot display, and in particular to a quantum dot display panel and a quantum dot display device. Background technique [0002] The particle size of quantum dot (Quantum Dot, QD) materials is generally between 1-10nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure, so the luminescence spectrum is very narrow (20 -30nm), high chroma purity and wide display color gamut, which can greatly exceed the color gamut range (>100%) of the (National Television Standards Committee, NTSC) (US) National Television Standards Committee (NTSC). Due to its special characteristics, quantum dots, as a new generation of luminescent materials, are gradually emerging in LED display applications. [0003] Quantum dot color film is a key component for display devices to achieve ultra-high color gamut full-color disp...
