What is the difference between projection white screen and gray screen
When choosing a home theater projection screen, some consumers have such questions, whether to choose a white screen or a gray screen? Some people's first reaction is that a white screen is better, and the color of a white screen is more transparent and vivid, making the picture clearer. However, due to the limited knowledge of the screen, little is known about the gray screen, and there is even a misunderstanding of the gray screen. A gray screen is called a 'high contrast screen'. Here's how it works: a gray screen can absorb more ambient light than a white screen, and white screens don't have this feature, so, the black level on the screen can be maintained, the white on the projection screen can still remain white, and the black is due to the ambient The interference of light is reduced and becomes darker, which directly leads to an increase in the contrast of black and white on the screen, thereby achieving the purpose of improving the contrast.
