Problems solved by technology

[0004] At present, due to the difference in the surface roughness consistency of the molded RGB LED lamp beads and the rough surface, the release of the material after molding requires the use of a release lubricant. Reflection, two bad factors make the surface consistency of the material pasted into a display screen too poor and affect the use effect

Embodiment 1

[0020] see Figure 1-Figure 2 , the present invention provides the following technical solutions: a method for surface coating to realize a matte surface, using a spraying machine to evenly coat a hybrid silicone resin 102 containing silicon dioxide particles on the surface of a colloidal material 101 with a smooth surface, so that It has roughness, and specifically includes the following steps:

[0021] Step 1: In the compression molding process, the colloidal material 101 is molded through a mold with a smooth surface to form a colloidal material 101 with a smooth surface. The surface adhesion of the mold with a smooth surface is small, and the colloidal material 101 is molded After that, the material can be easily detached from the mold surface, and the release agent is no longer used, which eliminates the reflection problem caused by the release lubricant; secondly, the surface of the material made from the smooth mold surface is also smooth, and the consistency is exactly...

Abstract

The invention belongs to the technical field of LED display, and particularly relates to a method for realizing a matte surface through surface coating. The method specifically comprises the following steps that firstly, compression molding processing is carried out on a colloid material through a mold with a smooth surface to form the colloid material with the smooth surface; secondly, the colloid material which is formed through compression molding in the first step and provided with the smooth surface is put into a spraying machine, and the surface of the colloid material provided with the smooth surface is evenly coated with hybrid silicon resin containing silicon dioxide particles through the spraying machine so that the surface of the colloid material can have roughness. According to the method, a layer of hybrid silicon resin containing the silicon dioxide particles is coated on the surface of the material through a spraying method under the condition of not changing the manufacturing process of a raw material, so that the problem of different light reflection degrees of the surface of the raw material is solved, and meanwhile, the color difference caused by inconsistent surface roughness of the raw material is solved; and a rough surface mold is not used for compression molding any more, so that a release agent is not used any more, and the problem of light reflection caused by a release lubricant is avoided.

Description

technical field [0001] The invention belongs to the technical field of LED displays, and in particular relates to a method for realizing a matte surface by surface coating. Background technique [0002] RGBled display is composed of red, green and blue light-emitting diodes. Different materials can be used to manufacture LED pixels of different colors. The most widely used are red, green and yellow, and the development of blue and pure green LEDs has reached practical stage. [0003] With the continuous development of LED display technology, the direct-display RGB LED display is more and more widely used, and people's pursuit of display quality is getting higher and higher. For the display, the matte surface can improve the contrast. , the consistency of the screen also needs to be highly consistent when the screen is black to give people a better visual effect; at present, the high blackness and matte surface are realized by adding carbon powder in the colloid, and molding...
