Abstract
The invention discloses an LCD screen and a display device, wherein a plurality of pixel units are arranged in the LCD screen, and each pixel unit is provided with a plurality of sub-pixel units displaying different colors; a quantum dot layer through which back light can penetrate is arranged in a position of an array substrate corresponding to a sub-pixel unit with at least one color of each pixel unit; the quantum dot layer emits light containing at least the color of corresponding sub-pixel unit after excited by ultraviolet light in sunlight; and a color filter is located between the quantum dot layer and an opposite substrate. When the LCD is used for displaying outdoors, the ultraviolet light in the sunlight irradiates the quantum dot layer, and the quantum dot layer emits light after excited by the ultraviolet light, so that light penetrating through the color filter is the sum of the back light and the light emitted by the quantum dot layer after the quantum dot layer is excited, the display luminance of the LCD screen is enhanced, and the viewability of the LCD outdoors is improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display screen and a display device. Background technique [0002] Quantum Dots (QDs), also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 20 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure, which can emit fluorescence after being excited. [0003] The emission spectrum of quantum dots can be controlled by changing the size of quantum dots. By changing the size of the quantum dot and its chemical composition, its emission spectrum can cover the entire visible light region. Taking CdTe quantum dots as an example, when its particle size grows from 2.5nm to 4.0nm, their emission wavelength can be red-shifted from 510nm to 660nm. [0004] At present, quantum dots can be used as...
