led vs wled

Short Answer

There is no difference between LED and WLED. WLED is just a marketing term and means “White LED”, which is the standard LED in LED displays anyways.

LED means Light Emitting Diode and WLED means White Light Emitting Diode. Did you come here to know the difference between LED and WLED? There’s no real difference between LED and WLED displays, it’s just a marketing gimmick.

Note that LED is not the same as LCD. As we mentioned, LED means Light Emitting Diode and LCD means Liquid Crystal Display. The difference between the two of them is the backlight – they are technically both LCD displays since a LED display utilizes a liquid crystal display. LCD displays have two polarized glass layers. These liquid crystals then proceed to block or pass the light to the display based on the picture. These crystals do not produce any light whatsoever, as the light comes from a series of lamps at the display’s back side – the backlight.

On an LCD display, where there is no mention of LED anywhere, these lamps are fluorescent lamps. On an LED display, these lights in the backlight are Light Emitting Diodes (LED). LED TV’s and monitors use less power and have a less even color distribution than LCD TV’s and monitors that do not have a LED backlight.
