Display devices are electronic components that visually present information, images, or videos. Common types include LCD (Liquid Crystal Display), LED (Light Emitting Diode), and OLED (Organic Light Emitting Diode) screens. These devices are widely used in televisions, computer monitors, and smartphones to provide clear and vibrant visuals. The performance of display devices is often measured by factors such as resolution, brightness, and color accuracy. Higher resolution displays, like 4K and 8K, offer more detail, while features like refresh rate and response time are important for smooth motion in gaming and video playback.
