WLED vs LED – What Is The Difference?

How do WLEDs and LEDs differ? Quite simply, they don’t. Let’s find out why.

It’s just a marketing gimmick to distinguish LEDs from WLEDs. The terms Light Emitting Diode (LED) and White Light Emitting Diode (WLED) are interchangeable.

Comparison of LEDs and CCFLs in LCDs.

There are two layers of polarized glass on LCDs (Liquid Crystal Displays). Light from the display is either blocked or passed through these liquid crystals, depending on the image.

A series of lamps located at the back of the display – the backlight – produce the light when the crystals do not produce any light.

It is possible to have an LED backlight or a CCFL (Cold Cathode Fluorescent Lamps) backlight for LCD displays.

LED TVs and monitors have advantages over CCFL LCD TVs and monitors, including using less power and being lighter and thinner.

LED backlighting is becoming increasingly common in LCD TVs and monitors. 

Using mini LED backlights makes LED displays even better.

Other OLED displays do not have a backlight and create their own light, so they can produce an infinite contrast ratio while generating better quality images. A LCD can also have IPS, TN, or VA panels.
