Problems solved by technology

[0003] At present, the display screen cover is mainly injection molded with plastic materials. However, due to factors such as molds and processes during the molding process, the surface of the display screen cover will be uneven, so that it is easy to accumulate on the surface of the display screen when encountering splashing water or rainy days. Moisture, the longer the moisture stays on the mask, the easier it is to cause the LED lamp beads or the internal circuit board to be damp and affect the use, reducing the waterproof performance of the LED display

Abstract

The invention discloses an LED display screen mask and a method for manufacturing the same. The LED display screen mask comprises a mask body and a hydrophobic film. The hydrophobic film is formed onthe outer surface of the mask body; the hydrophobic film comprises a first-layer film and a second-layer film, the first-layer film and the second-layer film are sequentially stacked on each other, the first-layer film is positioned on the outer surface of the mask body, the second-layer film is positioned on the first-layer film, materials for the first-layer film include dimethylbenzene, tert-butyl acetate, acetone, acrylamide polymers, preservatives and pigment additives, and materials for the second-layer film include acetone, silicon dioxide, preservatives and pigment additives. Owing tothe mode, the LED display screen mask and the method have the advantages that moisture attached onto the LED display screen mask can be reduced, and the waterproof performance of the LED display screen mask can be improved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to an LED display screen mask and a preparation method thereof. Background technique [0002] With the development of display technology, LED displays are widely used in various occasions such as indoor and outdoor advertising, sports, transportation, performances, exhibitions, leasing, and gatherings. In the existing LED display screen, a display mask is usually covered on the surface of the LED lamp to protect the LED lamp. [0003] At present, the display screen cover is mainly injection molded with plastic materials. However, due to factors such as molds and processes during the molding process, the surface of the display screen cover will be uneven, so that it is easy to accumulate on the surface of the display screen when encountering splashing water or rainy days. Moisture, the longer the moisture stays on the mask, the easier it is to cause the LED lamp beads or the inter...
