Problems solved by technology

[0005] The invention provides a pure-color diaphragm to solve the problem that when rhodamine-based dyes are used to enhance the color gamut, the agglomeration of the rhodamine-based dyes causes the absorption of shoulder peaks to be enhanced, so that the rhodamine-based dyes will absorb part of the blue light and green light, technical issues affecting luminous brightness

Abstract

The invention provides a pure-color diaphragm, a preparation method thereof and a display device. The pure-color membrane comprises a transparent base material and a pure-color substance dispersed inthe transparent base material, the pure color substance comprises a main body structure formed by cucurbituril and an object structure loaded on the main body structure, the object structure is formedby combining carboxyl-containing rhodamine dye and amino adamantane through chemical bonds, and the object structure is combined with the main body structure through adamantane to form the main-object structure. Rhodamine dyes and adamantane react to form the object structure; the main body structure formed by cucurbituril is utilized to enable the object structure to be loaded on the main body structure, and the purpose of dispersing the rhodamine dye is achieved, so that when the color gamut of the display device is improved by utilizing the pure-color diaphragm, the rhodamine dye can be prevented from being agglomerated to absorb part of blue light and green light, and the luminance and the display quality are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pure-color film, a preparation method thereof, and a display device. Background technique [0002] The development process of display technology is also the pursuit of the ability of color reproduction. Due to the increase in the types of colors, the color switching in the TV screen can be more natural, making the layers of the screen more distinct, showing more details and closer to reality. Effect. For liquid crystal displays, because the screen itself does not have self-luminous properties, the color gamut can be improved by adjusting the backlight, and the color gamut is mainly improved through the color filter filters of the three primary colors (red, green, blue); in addition , the color gamut can also be improved by adjusting the backlight. At present, there are two main ways to improve the purity of the backlight in the industry. One is to use blue LEDs combined with ...
