Which Is Better, DLED Or ELED?

DLED Technology

DLED refers to the direct-lit LED backlights which involves placing several LED bulbs directly behind the entire screen, so that the backlight can be evenly transmitted to the entire screen. The D-LED TV divides the LED backlight into a number of cells, and when showing black, directly turns off the light of its corresponding LED area, and the blackness levels produced are perfect and uniform. There are also other benefits to choose a DLED display. It uses local dimming to divide the entire screen into several zones of lights, as a result, it can enhance the contrast ratio eventually improving the overall picture quality. The results of higher numbers of LED lights covering the entire screen make it produce a high peak brightness level. However, the more LED lights are required, the more costly and higher power consumption it is. Besides, this makes it tend to be thicker than the ELED type.

ELED Technology

ELED means edge-lit backlighting, in which strips of LEDs are placed on the edges of the display, and the light produced from the LEDs at the edges gets spread across the entire screen with the help of diffusers. This makes it possible to build a thinner panel, but manufacturers do it at the expense of the lower picture quality because the number of LED lights is reduced by nearly seven times, it is easy to cause the nonuniform brightness, that is, it is brighter on edges but dimmer in middle. On the other hand, less power consumption can be achieved in ELED panel, and it is cheaper than DLED.

In short, the better type depends on your application. If you value a display with good picture quality and better local dimming control, you could choose a DLED display. If you can accept the reduction in picture quality in favor of a thinner panel, ELED would be suitable for you.
