ReunavaloLEDnäytöt, or edge-lit LED displays, are a type of flat-panel display technology that uses light-emitting diodes (LEDs) placed along the edges of the screen to illuminate the display panel. This is in contrast to direct-lit LED displays, where LEDs are positioned behind the entire panel. The light from the edge-mounted LEDs is diffused across the back of the screen, providing a more uniform illumination compared to older CCFL (cold cathode fluorescent lamp) backlighting.

This technology allows for thinner and lighter display designs, as the backlighting system is less bulky. Edge-lit LED displays are commonly found in televisions, monitors, and some tablet devices. The placement of LEDs along the edges enables sophisticated local dimming techniques in some implementations, where specific zones of the screen can have their brightness adjusted independently. This can lead to improved contrast ratios and deeper black levels.

However, edge-lit displays can sometimes exhibit less uniform backlighting compared to direct-lit models, with potential for light bleed or clouding, particularly in darker scenes. The precise implementation of diffusers and optical films plays a crucial role in mitigating these effects. Despite these potential drawbacks, the slim form factor and energy efficiency offered by reunavaloLEDnäytöistä have made them a popular choice for consumer electronics.
