An LED LCD backlight is a small strip of light, or light source, that are contained within a TV or monitor and provide lighting for the screen. All LED TVs have LCD panels with LED backlighting. Common misconceptions about LED TVs are that they are different from LCD displays, when in fact they are identical. LED can be described as a subset of LCD devices.
What is an LCD?
LCD stands for Liquid Crystal Display. This is a type or monitor, or flat-panel technology, that relies on millions or even billions of pixels, laid out in a rectangular grid. Each pixel of an LCD turns on and takes on a sub-pixel (RGB), which can be enabled, disabled, or red. If the pixels are off, each section will appear black. When all the sub-pixels (RGB) are on, the entire LCD will appear white. The arrangement of pixels provides sharp images on the display. They can be in an on- or off configuration.
The backlight of the LED makes the pixels appear brighter and richer from behind. Some LCDs do not have backlights, and some don’t use LED backlighting. Some LCDs also use CCFL lighting and Cold-Cathode Fluorescent Lamps. CCFL displays will soon be phased out to make way for LED-backlit panels.

Are LCD Panels Require A Backlight?
An LCD panel’s liquid crystals don’t need any illumination and must be illuminated by a separate component. In this instance, the LED backlighting is used.
Older display types such as cathode-ray tubes (CRT), produce illumination already so they don’t need an additional light source.
What is the difference between full LED and backlit LEDs?
- Edge lighting is bright, but not evenly distributed.
- Images with darker colors may appear washed-out.
- The light is evenly distributed throughout the display.
- For true black colors, individual nodes can be disabled.
Although it may seem confusing, LED-backlit panels can be very different to a full LED. Full HD illumination illuminates the entire screen with LED strips along the edges. LED-backlit panels are brighter and more accurate than full HD. This is possible because of an evenly distributed light source at the rear.
This can cause a display to have a different picture, especially when there are dark scenes or true black colors. For example, LED-backlit displays can make dark scenes appear washed out due to the way the light is directed towards the edges and then spreads out into the center.
Full LEDs can, however, achieve true blacks with uniform brightness levels due to the fact that the light is evenly distributed across the panel. The full-LED panel’s lights can also be turned off or disabled individually to create darker images.
Which is better LED or LED backlit?
Both LED-backlit and LCD-backlit panels produce vivid and bright images because they are both LCD panels. The light source used to illuminate the scene can make it appear brighter or less vibrant depending on whether it is evenly distributed lighting, edge backlighting, or unevenly distributed lighting. Full LED panels offer a better picture but are more costly.
What is the meaning of an LED-backlit LCD Monitor?
An LED-backlit LCD Monitor is an LCD panel that has LED backlights. It’s similar to TVs and other displays. A monitor or computer monitor is often different from other displays in that they do not include a builtin tuner. This is necessary to access cable. Many include multiple video or display ports such as HDMI, DisplayPort and VGA. These are intended to be used as secondary or primary displays for laptops and desktop computers.
The majority of monitors have full LED panels and a distributed light source. They can provide a sharper, brighter image that is perfect for media and computer-related activities.
Are You Looking for LCDs with Backlights in Other Places?
Monitors and TVs with LED-backlit LEDs are used in many places, including ATMs and cash registers, digital billboards and fitness equipment such as treadmills, vehicle infotainment system, gas station pumps, Pachinko and casino machines, as well mobile devices and other devices.
Just by looking around, you can see many examples of LED-backlit and LCD panels.
- How can I clean an LCD TV screen
To clean flat-screen TV turn it off and use a microfiber cloth to gently wipe it. Use distilled water, or a similar ratio of white vinegar to dampen the cloth.
- Where can I find a replacement LCD TV-screen?

- How can I tell if my monitor has LED backlighting or not?
The screen should be turned black. Next, look around the screen to find dark and light patches. You can also visit the manufacturer’s site.
- What’s the difference between LED and LCD TVs?
All LED TVs are LCD TVs . However, not all LCD TVs can be considered LED TVs. A TV that is marketed as LCD without mentioning LED will probably use a different type or backlighting, such as CCFL.
