Problems solved by technology

[0002] At present, the backlight in the liquid crystal display usually adopts ordinary yellow phosphor backlight, which makes the color gamut of the liquid crystal display low; in addition, there are overlapped areas between the three primary color film filters currently used, such as red and green light with yellow orange There is an overlapping area in the 560-610nm band of light and an overlapping area in the 480-510nm band of blue-green light, resulting in low purity of the RGB three primary colors, which leads to the inability to improve the color gamut of the display

Abstract

The invention provides a color conversion film material, a color conversion film and a display device, wherein the color conversion film material comprises a first compound and a second compound, andthe mass ratio of the first compound to the second compound is (0.4-1.6):(0.3-1.7). According to the color conversion film formed by the color conversion film material, the thermal stability of the color conversion film is improved, the color conversion film is applied to the display device, the color gamut of the display device is improved, and the cost is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a color conversion film material, a color conversion film and a display device. Background technique [0002] At present, the backlight in the liquid crystal display usually adopts ordinary yellow phosphor backlight, which makes the color gamut of the liquid crystal display low; in addition, there are overlapped areas between the three primary color film filters currently used, such as red and green light with yellow orange There is an overlapping area in the 560-610nm band of light and an overlapping area in the 480-510nm band of blue-green light, resulting in low purity of the RGB three primary colors, which leads to the inability to improve the color gamut of the display. Contents of the invention [0003] The application provides a color conversion film material, a color conversion film and a display device, so as to improve the thermal stability of the color con...
