80-inch Laser TV Screen

The Yuying Laser TV screen is a black grating structure.  The principle is to use special technology to make the screen with zigzag cross-section.

On the surface of the black screen, there are many very fine prism structures in the transverse direction. As long as its function is to absorb and not reflect the light from the upper part of the screen  , it mainly reflects the light from the lower part of the screen to achieve the purpose of anti-light: the principle is to use special technology to make the screen with a zigzag cross-section.  One side absorbs the interfering light and reflects the projected light. The white slope is the reflecting layer.   The light of the projector is projected from the bottom to the top of the white reflecting layer and then reflected into our eyes. The interfering light from the top will be absorbed by the black parallel laye r.

 

When you look down at the screen, with the change of angle,  the color of the screen you see will become completely black, while when you look up , with the change of angle, the whole screen will become completely white .

 

Ultra-short focal black grating is a special optical sawtooth structure,  which can prevent 98% of ambient light effect, showing projection true color and no reflection phenomenon.

 

According to the optical principle,  with the revolutionary products developed by the ultra-short focus projector,  the projection distance of only 40 cm can reach 100', the color is delicate, the picture is soft, the restoring degree is high, and the eyes are not tired for a long time.

 

Gain 0.5, half-angle gain 75 degrees. The screen shading layer blocks the ambient light, so that the picture has an ideal contrast, and the clear image can be viewed without turning off the light.
