Problems solved by technology

But the problem is that carbon black BM has a high dielectric constant, which can easily lead to the failure of TFT in LCD; in addition, because carbon black BM mainly uses carbon black particles (Carbon black) to absorb light, its particle properties have a certain degree of light Reflection, especially higher reflectivity for longer wavelength light

Embodiment Construction

[0034] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals.

[0035] This application is aimed at the black matrix material of the display panel in the prior art. Due to its high dielectric constant, it is easy to cause the failure of the TFT device, and there is a technical problem that the reflectivity of light is high, which affects the performance of the display panel. This implementation example can solve this defect.

Abstract

The application provides black matrix dispersion liquid and a preparation method thereof, and a display panel. The display panel comprises an array substrate and an opposite substrate which are oppositely arranged, and a liquid crystal layer located between the array substrate and the opposite substrate; the array substrate or the opposite substrate comprises a black matrix corresponding to a clearance part between two adjacent pixel units, wherein the material of the black matrix comprises metal nano particles uniformly distributed in the surface of the dispersion resin and wrapped with the silicon dioxide wrapping, and blue dye molecules and red dye molecules uniformly fixed in the dispersion resin through the chemical bonds.

Description

technical field [0001] The present application relates to the technical field of display manufacturing, in particular to a black matrix dispersion, a preparation method thereof, and a display panel. Background technique [0002] Thin film transistor liquid crystal display TFT-LCD module is composed of backlight system, color filter (CF), thin film transistor (TFT), and liquid crystal between TFT and CF substrate. In a traditional liquid crystal display panel, the color filter CF mainly divides the light in the backlight into three colors of red (R), green (G), and blue (B), and the black matrix (Black Matrix, BM) is used to separate the sub-pixels of each color, block the gaps between the sub-pixels of each color, and prevent color mixing and light leakage. At present, the traditional technology is to separate the RGB pixels of the color filter CF with BM. [0003] According to the material composition of BM, it can be divided into metal oxides, carbon black, titanium blac...
