Electric curtain
The price of the electric screen is higher than that of the manual screen. It is operated by the remote control, easy to maintain and easy to install. The screen is evenly lowered from the two ends to ensure that the screen is not affected by external forces, and the screen can be maintained for a long time. Long-term use is not easy to produce ripples, and this curtain can also support ceiling or wall installation.

Other identification   Â
White plastic screen: Shows the best image, text and data effects when the surrounding lights are adjustable. The fiber is evenly dispersed and projected into each display area, the color is natural and realistic, the brightness is 1-1.5 times the gain, and the viewing angle is 50°. The effect is excellent when the ambient light (including the reflection of walls and ceilings) is controllable.
Perspective identifier
Glass bead curtain: It is specially treated with five layers of special materials. The glass beads (glass powder) are evenly distributed on the surface of the screen to increase the reflection brightness. The text, image and data are bright and delicate, and the brightness is up to 2-2.5 times. The viewing angle is 30°, but the increase in brightness will lose a certain contrast.
Gain identification
Gray screen: often referred to as “high-contrast screenâ€, the gray screen absorbs more ambient light than the white screen (the white screen does not have this function), so that the black level on the screen is maintained, and the screen is white. It can still be kept white, while black is reduced by the interference of ambient light, which makes it darker. This directly leads to an increase in the contrast between black and white on the screen, thus achieving the purpose of improving contrast. The gray screen is the mainstream screen of the current home market. .
