Problems solved by technology

[0003] The traditional color filter substrate mainly uses red, green and blue (RGB) color-resisting materials to realize the color filtering function of light. The thicker the RGB color-resisting material, the purer the color of the light obtained, and the higher the color gamut of the liquid crystal display. The transmittance will be sacrificed
In addition, since the color resist material is mainly composed of organic resin and pigments, it is easy to form ionic impurities, and these ionic impurities are easy to diffuse to the surface of the alignment film and form a direct current (DC) under the action of the internal bias voltage of the display panel. DC) to bias the electric field, thereby aggravating the afterimage

Embodiment 1

[0056] This embodiment provides a color filter substrate, such as figure 1 As shown, it includes a substrate 1, and also includes a color filter structure disposed on the substrate 1. The color filter structure includes a non-periodic nanostructure layer 2 and a light guide structure layer 3, and the non-periodic nanostructure layer 2 is disposed on the side of the substrate 1. , the light guide structure layer 3 is arranged on the side of the non-periodic nanostructure layer 2 away from the substrate 1, the light guide structure layer 3 can make the incident light enter the aperiodicity in the area where the different sub-pixels 4 are located at different incident angles. On the nanostructure layer 2 ; the non-periodic nanostructure layer 2 can couple and interfere incident light, so that the regions where different sub-pixels 4 are located emit light of different colors.

Abstract

The invention provides a color filter substrate, a preparation method thereof, and a display panel. The color filter substrate includes a base and a color filter structure arranged on the base. The color filter structure includes a non-periodic nanostructure layer and a light-guiding structure layer. Set on the side of the non-periodic nano-structure layer away from the substrate, the light-guiding structure layer can make the incident light incident on the non-periodic nano-structure layer in the area where different sub-pixels are located at different incident angles; the non-periodic nano-structure layer The layer can couple and interfere the incident light, so that the regions where different sub-pixels are located emit different colors of light. The color filter substrate can improve the color gamut without sacrificing the transmittance, and can also weaken the DC bias electric field inside the display panel caused by ionic impurities, thereby improving the display afterimage caused by the DC bias electric field .

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a color filter substrate, a preparation method thereof, and a display panel. Background technique [0002] The color film substrate (Color film, referred to as CF) is the key material to realize the color display of the thin film transistor liquid crystal display panel (TFT-LCD), and occupies the highest cost in the display screen. The role of the CF substrate is to enable the light passing through the liquid crystal molecules to display different colors after passing through the color filter, and then achieve the effect of displaying color patterns through the combination of different colors of light. [0003] The traditional color filter substrate mainly uses red, green and blue (RGB) color-resisting materials to realize the color filtering function of light. The thicker the RGB color-resisting material, the purer the color of the light obtained, and the higher the...
