An LC panel, also known as a liquid crystal panel, is a flat display screen that uses liquid crystals to create images and text. These panels are commonly used in electronic devices such as televisions, computer monitors, and smartphones. The liquid crystals in an LC panel are able to change their orientation when an electric current is applied, allowing for the display of different colors and images. This technology allows for high-resolution and energy-efficient displays, making LC panels a popular choice in modern technology.
