Embodiment Construction

[0025] The following description of the embodiments refers to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the attached drawings. direction. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0026] In one embodiment, the composite material of the present invention includes a high light absorption material and a low reflection material.

[0027] The light absorption coefficient of the high light absorption material is 3.5-4.5, and the refraction coefficient of the high light absorption material is 0.01-0.1. In this embodiment, nano-silicon is selected as the high light-absorbing material. In the visible light wavelength range of 400-700 nm, the light absorption coefficie...

Abstract

The invention discloses a composite material, a preparation method thereof, and a display panel. The raw material of the composite material includes a high light absorption material and a low reflection material, the light absorption coefficient of the high light absorption material is 3.5-4.5, and the light absorption coefficient of the high light absorption material is The refractive index is 0.01-0.1; the light absorption coefficient of the low reflection material is 2-3, and the refractive index of the low reflection material is 1-1.5. The composite material of the present invention strengthens the absorption of visible light through granular nano-silicon, and uses the low-reflection material as a matrix to form a three-dimensional composite porous structure, further weakening the specular reflection of light, and improving contrast and visual effects.

Description

technical field [0001] The invention relates to the fields of displays and the like, in particular to a composite material, a preparation method thereof, and a display panel. Background technique [0002] In the liquid crystal display panel, with the development of high-generation TFT-LCD, the display panel is evolving towards large size, high image quality, and high resolution, and with the increasing size, the number and length of metal wiring have increased significantly . In order to increase the visual and appearance effects of the display panel, narrow bezels or even four-sided bezel-less technologies are currently being developed. However, this method faces the disadvantages of edge light leakage and reduced contrast, just like the side-facing array light bars. Some companies on the market have developed a scheme design with the array light bar facing outward and actually produced LCD TV products, but the effect is not good. When the array light bar is facing outward...
