Colored filter substrate and display module

Abstract

The invention provides a colored filter substrate and a display module. The colored filter substrate comprises a substrate body, black matrixes arranged on the substrate body, a color resistance layer and a quantum dot layer, wherein multiple subpixel areas are defined by the black matrixes, the color resistance layer is arranged in the subpixel areas and located on the substrate and comprises at least two colored color resistance units in different colors and at least one transparent color resistance unit, the quantum dot layer is arranged in the subpixel areas and located on the side, away from the substrate, of the color resistance layer, and quantum dots which can generate corresponding colors after being stimulated are arranged in the quantum dot layer and correspond to the colored color resistance units in different colors. In this way, the colored color resistance units just need to filter out exciting light which is not completely absorbed and mixed with light in the corresponding color, light loss is reduced, and the light utilization rate of the colored filter substrate is increased.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, and more specifically, to a color filter substrate and a display module. Background technique [0002] Existing display panels such as figure 1 As shown, the color filter substrate includes a plurality of pixel units 101, and each pixel unit 101 includes a red sub-pixel unit 1010, a green sub-pixel unit 1011 and a blue sub-pixel unit 1012, wherein the red sub-pixel unit 1010 has The red filter is used to pass through the light in the red band and filter out the light in other bands; the green sub-pixel unit 1011 has a green filter, which is used to pass through the light in the green band and filter out the light in other bands; The blue sub-pixel unit 1012 has a blue filter for passing light in the blue band and filtering out light in other bands. [0003] For each sub-pixel unit, because the filter filters out most of the light through a small part of the light, for example, th...
