Salisbury screen

Imagine you are watching a movie on a big TV and there's a bright light coming from behind you that makes it really hard to see the screen. That's where the Salisbury screen comes in!

The Salisbury screen is a special filter that helps you see things on a screen even when there's a bright light shining on it from behind. It's kind of like putting sunglasses on the screen, but instead of making everything dark, it only lets certain colors of light through.

The screen is made of layers of special materials that work together to absorb and reflect certain colors of light. When the bright light shines on the screen, the layers absorb most of the unwanted colors and reflect mostly the colors you want to see.

So, even though there's a bright light behind you, the Salisbury screen helps you see the movie or whatever is on the screen!

Overall, the Salisbury screen is a special kind of filter that helps you see things on a screen even when there's a bright light shining on it from behind.
