Abstract

The embodiment of the invention provides a color film substrate and a display device, and relates to the technical field of display. The efficient light filtering effect can be achieved, and the backlight utilization rate is increased. The color film substrate comprises multiple pixel units. Each pixel unit comprises a blue sub-pixel, a green sub-pixel and a red sub-pixel. Each blue sub-pixel comprises a first photonic crystal layer on a substrate body and used for making blue light emitted to the color film substrate to pass. Each green sub-pixel comprises a second photonic crystal layer and a first light emitting medium layer which are arranged on the substrate body in sequence, wherein the first light emitting medium layer emits green light under the stimulation of the blue light, and the second photonic crystal layer is used for making the green light to pass. Each red sub-pixel comprises a third photonic crystal layer and a second light emitting medium layer which are sequentially arranged on the substrate body in sequence, wherein the second light emitting medium layer emits red light under the stimulation of the blue light, and the third photonic crystal layer is used for making the red light to pass. The invention further provides a preparation method for the color film substrate and the display device with the color film substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a display device. Background technique [0002] Currently mass-produced high-resolution full-color display devices using OLED (Organic Light-Emitting Display) as the backlight source are usually realized by laminating a WOLED (white OLED) substrate and a color film substrate. [0003] However, since the white light emitted by WOLED is composed of light of different frequency bands, after being filtered by the color filter, most of the light is absorbed by the red, green and blue color filter pigments in the color filter substrate. , the filter efficiency is low, and the backlight loss is large. Contents of the invention [0004] In view of this, in order to solve the problems in the prior art, the embodiments of the present invention provide a color filter substrate and a display device, and the color filter substrate can realize the effec...
