An edge-lit LED is a type of LED-backlit display or screen that utilizes bulbs positioned along the edges of the screen to provide illumination. This design allows for a sleek and thin display, as the LEDs are not directly behind the screen but rather placed around its perimeter. The key feature of edge-lit LEDs is the use of light guides, which help distribute the light emitted by the bulbs evenly across the entire screen. These light guides ensure uniform brightness and prevent areas of uneven illumination, resulting in a more consistent viewing experience. By positioning the LEDs along the edges of the screen, the light is directed towards the center, creating a more muted effect compared to other backlighting methods. This design choice also allows for thinner displays and better cooling capabilities.
