Description

Display screen mask

Technical Field

The utility model relates to a display screen field, in particular to display screen face guard.

Background

Because of its characteristics such as high brightness, high resolution and big vision, LED display screen is widely used in occasions such as stage or exhibition. On the occasions such as stages and exhibitions, ambient light (such as lamplight and sunlight) is bright, and the LED display screen is required to have good effect and form high contrast with the ambient light. In order to reduce the interference of ambient light to the display effect of the LED display screen, a mask is generally installed on the LED display screen, and a rib extending transversely or longitudinally is provided on the mask as a light blocking part, so that on one hand, a part of light can be absorbed; on the other hand, part of light can be reflected and disturbed to reduce the entering of ambient light into human eyes and improve the contrast ratio of the LED display screen and the ambient light. It is now generally believed that the darker the viewing of the mask in ambient light, the more the contrast of the LED display screen with ambient light is improved. The inventor finds that the existing mask is dark in the ambient light and cannot be watched from multiple angles, and the mask is whitened when being watched from one angle.
