Only when the projector is matched with the screen will there be a better picture display. I believe friends all understand this truth. But the biggest question is which kind of effect is better for the projection screen. Some projector users will choose white plastic or glass fiber screens with higher brightness gain, and some projector users will choose light resistant screens with better color and contrast. Today, let’s take a look at which one is better, the black crystal screen or the gray crystal screen.
The black crystal screen and the gray crystal screen are essentially darker light-resistant screens, which have a significant improvement in the black level and level of the picture; at the same time, the black crystal screen and the gray crystal screen have a wide viewing angle, which can reach 160 degrees, close to White wall; in addition, it can completely eliminate the appearance of foggy white background.
One of the differences between the black crystal screen and the gray crystal screen is the difference in color. Many friends will project the projector on the white wall. They will mistakenly think that the effect on the white-based screen will be better. In fact, the black crystal screen Both the gray and gray crystal screens are mainly dark, while the black screen will be darker in color and have a better picture effect.
The second difference between the black crystal screen and the gray crystal screen is the screen gain. The black crystal screen gain is about 0.65-0.7, and the gray crystal screen is about 0.85-0.9. The difference in gain also allows the black and white screen and gray crystal screen to have different light and dark details. different. The gain effect of the gray crystal screen is higher, and the picture effect of the bright part will be better. After all, the principle of a home projector is to reflect into the eye after projecting the picture, while black can absorb more light. Although the black level of the picture is deeper, the reflection of the picture is still slightly inferior.
According to the characteristics of the light-resistant screen, if you work in an environment with strong light, you must consider the light-resistant screen with better light resistance. Light-resistant black crystal screen and gray crystal screen, the gray crystal screen will be better, but the price will be higher.
In summary, the gray screen is stronger in the picture gain, and the color of the black screen is deep, you can choose according to your needs.
