Abstract

An embodiment of the present invention provides a quantum dot display panel and a quantum dot display device. The quantum dot display panel includes: a backlight module composed of an ultraviolet light backlight module and a white light backlight module; The color film structure and the white light transmission area, the quantum dot color film structure covers the ultraviolet light backlight module, and the white light transmission area covers the white light backlight module; the red light quantum dot color film structure has multiple red light quantum dot structures, and the green light quantum dot color film The vertical projections of the multiple green light quantum dot substructures of the structure, the multiple blue light quantum dot substructures of the blue light quantum dot color film structure, and the multiple white light transmission subregions of the white light transmission region on the plane where the backlight module is located do not overlap. The technical solution provided by the embodiment of the present invention avoids the use of color filters and improves luminous efficiency; optimizes the performance of quantum dots to ensure the reliability of the color filter structure; directly enhances the display brightness through the white light transmission area to maximize the energy of the backlight source use.

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...
