Product Details

The screen of Yuying laser TV has a black grid structure, and the principle is to use a special process to make a screen with a zigzag cross section.

On the surface of the black grid screen, there are very small prism structures in the horizontal direction. Its only function is to absorb and not reflect the light from the top of the screen, and mainly reflect the light from the bottom of the screen to achieve the purpose of anti-light: the principle is to use a special The process is made into a screen with a zigzag cross section. One side absorbs the interference light and the other side reflects the projection light. The white slope is the reflective layer. The light from the projector is projected onto the white reflective layer from bottom to top and then reflected into our eyes, while the interfering light from above will be reflected by the black parallel layers absorbed

When looking down at the screen, as the angle changes, the color of the screen you see will become completely black, and when looking up, the entire screen will become completely white as the angle changes.

The ultra-short-focus black grid anti-light mode is a special optical sawtooth structure, which can block 98% of the ambient light effect, projecting true colors without reflection.

According to the optical principle, combined with the revolutionary product developed by the ultra-short-throw projector, the projection distance is only 40cm and the picture can reach 100''. The color is delicate, the picture is soft, and the degree of reproduction is high. The eyes will not be tired after watching for a long time.

The gain is 0.5, and the half-angle gain is 75 degrees. The screen shading layer blocks ambient light so that the picture has an ideal contrast, and you can watch clear images without turning off the lights.
