An LCD monitor is a type of display screen that uses liquid crystals to produce images. These monitors are popular for their slim design and energy efficiency compared to older CRT monitors. They work by manipulating light through liquid crystals, which can change their alignment when an electric current is applied. LCD monitors are commonly used in computers, televisions, and various electronic devices. They offer clear images and vibrant colors, making them suitable for tasks like gaming, graphic design, and everyday computing. Their lightweight nature also makes them easy to mount on walls or move around.
