SaveScreens are an essential part of our modern world. We use them for everything from work to play, and they have become an indispensable tool for learning. But what exactly are screens, and how do they work? In this article, we will explore the basics of screens, including their history, how they are made, and how they are used in different applications.
The first screens were developed in the early 19th century. These early screens were simple devices that used a rotating cylinder to display text and images. The first practical screen was developed in 1923 by Vladimir Zworykin, a Russian inventor. Zworykin's screen used a cathode ray tube (CRT) to display images. CRT screens were used in televisions and computer monitors for decades, and they are still used in some applications today.

Screens work by emitting light. The light is emitted from a backlight, which is located behind the screen. The light is then directed through a series of layers, including a polarizing filter, a color filter, and a liquid crystal layer. The liquid crystal layer is made up of tiny crystals that can be aligned in different ways to control the amount of light that passes through them. When an electric current is applied to the liquid crystal layer, the crystals align themselves to allow light to pass through. When the electric current is turned off, the crystals align themselves to block light. This process creates the images that we see on the screen.
Screens are used in a wide variety of applications, including:
Screens are essential for our modern world, and they are constantly evolving. As technology advances, we can expect to see even more innovative and exciting uses for screens in the future.
