An LCD monitor is like a big window that can change its colors and pictures by using tiny lights inside it.
Imagine you're looking at a window made up of many small squares, each square can be red, green, or blue. When they all work together, they make the whole picture on the screen look real. These little squares are called pixels, like the tiny spots that make up your favorite cartoon on TV.
How the Tiny Lights Work
Inside the monitor, there’s a special layer called the liquid crystal, it's like a flexible window that can twist and turn. When electricity goes through it, these crystals change how light passes through them.
Behind this liquid crystal layer is a bright backlight, like a flashlight shining from behind the window. The light goes through the liquid crystal, then through another special layer that helps mix the colors, and finally, we see the picture on the screen.
It's just like when you use colored cellophane to make different pictures, each color is controlled by how much light passes through it. That’s what makes your monitor show all your favorite videos and games!
