Quantum dot color film structure suitable for multi-primary colors and ultra-high resolution

Abstract

The invention relates to a quantum dot color film structure suitable for multi-primary colors and ultra-high resolution. A black matrix barrier wall is photoetched or printed on the upper surface of aglass substrate, a corresponding color sub-pixel region of the black matrix barrier wall is filled with quantum dot paste, an encapsulation layer is used for sealing and solidifying the quantum dot paste in the corresponding color sub-pixel region of the black matrix barrier wall, and a blue light prevention film layer and a light adjustment film layer are sequentially disposed on the encapsulation layer from bottom to top. Blue light is used for exciting quantum dots in the corresponding color sub-pixel region of the black matrix barrier wall to emit corresponding color monochromatic light.The blue light prevention film layer and the light adjustment film layer are used for increasing the color purity of the transmitted light of the corresponding color sub-pixel region of the black matrix barrier wall and for reducing turbulence, the transmitted light is used as a positive straightening and emission effect, and the brightness of positive transmitted light is effectively improved. The quantum dot color film structure can overcome the problems that the color purity is lowered and the light utilization rate is reduced due to the poor color conversion rate in the process of light emission of the blue light-excited quantum dots.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot color film structure suitable for multi-primary colors and ultra-high resolution. Background technique [0002] In recent years, liquid crystal display technology has been widely used in various fields of society. With the continuous improvement of people's living standards, the requirements for the display quality of liquid crystal displays are also gradually increasing, and there are high requirements in terms of color gamut and brightness. The emergence of quantum dots as a new type of material can better solve this problem. Quantum dots have the advantages of tunable luminous wavelength, narrow luminous line width, high luminous efficiency, and good optical, thermal and chemical stability. After solution processing, spin coating or Photoluminescence after inkjet printing is a new generation of luminescent materials used in solid-state lighting and full-color f...
