When researching display devices, you’ll probably come across light-emitting diode (LED)-backlit liquid-crystal displays (LCDs). They are LCDs that use an LED backlighting system. The pixels within an LED-backlit LCD consist of liquid organic matter. Behind the pixel layer is a collection of LEDs. When turned on, the LED will illuminate the liquid pixels to create visible images. Even if you’ve heard of LED-backlit LCDs, however, there are several common myths about them that you should ignore.

#1) Same as OLEDs

Some people assume that LED-backlit LCDs are the same as organic LEDs, but this isn’t the case. LEDs. LED-backlit LCDs feature a backlighting system, whereas OLEDs do not. The backlighting system used in their construction consists of LEDs, which is why they are known as “LED-backlit LCDs.” OLEDs, in comparison, feature self-illuminating pixels that don’t require a backlighting system.

#2) Not as Common as CCFL-Backlit LCDs

In the past, cold-cathode fluorescent (CCFL) was the leading backlighting technology for LCDs. You can still find some CCFL-backlit LCDs available for sale today, but LED-backlit LCDs have since taken their place. Most LCDs manufactured and sold today now use LED backlighting. LED-backlit LCDs have surpassed their CCFL-backlit counterparts in terms of popularity.

#3) Use the Same LED Configuration

Another common myth is that all LED-backlit LCDs use the same LED configuration. The LED configuration, of course, refers to the way in which the LEDs are positioned. All LED-backlit LCDs feature a collection of LEDs, which they use to illuminate their liquid pixels. But there are different configurations available for LED backlighting. Some LED-backlit LCDs use an edge-lit configuration, whereas others use a direct-lit configuration.

#4) High Energy Consumption

Think LED-backlit LCDs consume a lot of energy? Think again. Like all display devices, they require energy to illuminate their pixels. Most of the energy consumed by a given display device is used for illumination purposes. But LED-backlit LCDs are actually energy efficient. Since they use LED backlighting, they consume less energy than other display devices. A typical LED-backlit LCD, in fact, consumes about 20% to 30% less energy than a CCFL-backlit LCD.

#5) Contains Mercury

LED-backlit LCDs don’t contain any mercury. Mercury is used in CCFL backlighting systems. LED-backlit LCDs use an LED backlighting system that leverages many small diodes. There are no CCFLs in LED-backlit LCDs, meaning they don’t contain any mercury. This makes LED-backlit LCDs an environmentally friendly choice for consumers and business owners.
