Abstract

The invention provides an application of a black base material in an LED spliced screen product. A processing method of the LED spliced screen comprises the following steps of inner layer processing,pressing, drilling, electroplating, circuit processing, solder mask processing, surface treatment, forming, testing and finished product inspection. Black colloid is adopted in the pressing process; and transparent color ink is adopted in the solder mask process. The black polypropylene material filled with the black pigment is used, the consistency of the base color of the base material is ensured, and the problems of solder mask and insulation are solved by adopting transparent ink on the surface.

Description

technical field [0001] The invention belongs to the technical field of LED splicing screen processing, and in particular relates to the application of a black base material in LED splicing screen products. Background technique [0002] LED displays have been widely used in public places such as advertisements, stations, banks, shopping malls, etc. [0003] Long, good color and other advantages. In the prior art, LED display screens are generally divided into two types. The first type of LED display screen has a light-transmitting hole on the lamp board, and the light-transmitting hole is generally strip-shaped. Optical performance, used for stage display effect with good light transmission, the second type of LED display is that the light board does not have a light transmission hole, the second type of LED display has good light-shielding performance, and is used for needs of good light-shielding performance Stage display effect. At present, for some large LED displays...
