Light-Resistant Screen vs White Wall-Click here to see difference


Introduction: For projector users, whether to choose a screen or cast it on a white wall? What is the difference between the screen and white wall projection effect? In this article, we will see the comparison of the projection effect between the light-resistant gray curtain and the white wall.

As a projector player, the purchase of curtains is an unavoidable topic. There are many types of projector screen on the market, and the prices range from hundreds to tens of thousands. The purchase is indeed dazzling. It seems that the overall performance and cost performance are good-light resistant curtain (gray curtain).

First of all, let's talk about the appearance of the anti-reflective curtain. The anti-reflective curtains currently on the market are generally gray, and will appear gray to black according to different angles or light. As shown below, the look and feel under different angles and light environments.

So don't make a mistake, ask what is the difference between the gray curtain and the white curtain, and there are many types in it. Not introduced here.

Time is more than 4 pm, first measure the effect under the light. It can be seen that the effect of the anti-light curtain on the white wall is quite obvious.

The principle of Light-Resistant Screen
Speaking of the principle of the Light-Resistant Screen, it is actually very simple, that is, the projected light is concentrated in the direction of the viewer, and the light from other directions is either absorbed or not reflected, so as to reduce the interference of stray light and improve the projection. Use effect in high light environment.

Due to the different angles of light projector, the light-resistant screens of ordinary telephoto and ultra-short focus machines are somewhat different. The ultra-short focus machine projects from the bottom up. The light resistance only needs to reflect the light here to the user's eyes. Others The direction is not reflected. The best effect is the Fresnel optical curtain, which can resist the upper and left and right sides of the light. The black grid uses black and white prisms, which absorbs stray light and reflects the projected light. The light interference effect on the top is the best, but the effect on the left and right sides is worse, both of which are directional reflective curtains. In traditional telephoto, since the angle of the light projected onto the curtain is generally not very large, whether it is a ceiling mount or a tabletop dress, it is difficult to achieve the anti-light absorption and reflection of the telephoto machine through a specific optical lens. Mostly through the optical coating, the absorption coating absorbs the environmental interference light, and the reflective layer reflects the projection light projected from the front, which belongs to the omnidirectional reflective curtain. What I got this time is the latter, which is advertised as a multi-layer film microstructure anti-light curtain, with a gain of 1.2, but an angle of 160 degrees. For projection, the brightness is required to be above ANSI 500 lumens.
