A color conversion film and a liquid crystal module composed thereof

Abstract

The invention relates to a color conversion film and a liquid crystal module formed by the color conversion film. Include a substrate, on top of which are tightly spaced lattices, 3 lattice are periodically embedded or coat with blue on that lattice respectively, Green and red spectral conversion material, which comprise a quantum dot material as an optimal choice, a transparent UV glue is coatedon that substrate aft embedding or coating the color conversion material, and then the substrate is covered to form a complete color conversion color film; The color conversion film can improve colorpurity, light efficiency and color gamut area under the cooperation of the traditional color filter film in the liquid crystal display device. The invention can be applied to a liquid crystal displayto improve its light efficiency, improve color purity and increase color gamut area.

Description

technical field [0001] The invention relates to a color conversion film and a liquid crystal module composed thereof. Background technique [0002] The application of colorization technology using a color conversion method to liquid crystal displays, organic EL displays, liquid phase display technology, lighting, and the like is being extensively studied. The so-called color conversion is to down-convert the light emitted from the light source into light with a longer wavelength, for example, it means down-converting a blue light source with a shorter wavelength into a green or red light source. By making the composition with this color conversion function into a film and combining it with, for example, a blue light source, it is possible to simultaneously output the three primary colors of blue, green, and red from a single blue light source through the conversion film, that is, to achieve output of white light. A full-color display can be produced by using a white light ...

[0005] Invention patent application CN107922835A discloses a color conversion composition, a color conversion film, and a backlight unit comprising the same, a display and lighting, and an invention patent application CN107709516A discloses a color conversion composition, a color conversion film, and a light-emitting device comprising the color conversion film, a liquid crystal For display devices and lighting devices, although the color conversion compositions described in these two patent applications have explained the emission wavelength ranges of green and red luminescent materials, they have not explained how to select and the selection method specifically, therefore, it is impossible to rely on this method Quickly select an efficient and wide color gamut spectral combination scheme that matches the color filter film in the LCD module

[0007] Utility model patent CN205404872U discloses a grating light guide plate based on quantum dots. The backlight module needs to change the principle of the traditional module structure and replace it with a new type of light guide plate. This solution is not conducive to the promotion of existing modules. application
