The entire surface of both sides becomes dull due to the reflection of sunlight.
The surrounding lighting may interfere with the screen and cause glare, or wind foliage may appear on the screen, making it difficult to see both images and often causing eye strain. Therefore, they have devised ways to prevent light from the surroundings from directly hitting the screen, and have also put a screen made of transparent plastic or the like on top of the screen to scatter the reflected light.
