Difference Between LED Backlit and Full LED TV

April 2022 · 5 minute read

The Light-Emission-Diodes are responsible for the backlights of a few televisions. Due to their high efficiency, LED TVs have been popular among various consumers around the globe. Furthermore, these LEDs are either situated behind the screen, like full-array (Full LED TV), or at the edges/ sides of the screen, like LED Backlit TVs. 

LED Backlit vs Full LED TV

The main difference between LED Backlit and Full LED TV is that the LED Backlit have LEDs only at the edges or sides of the televisions. However, on the other hand, Full LED TVs have LEDs installments behind the screens, thereby spreading out evenly over the entire screen of the television. 

LED Backlit uses LEDs for backlighting the display rather than installing traditional cold cathode fluorescent backlighting. In this way, the LED Backlit TVs emphasize the depth behind the subject and give images a greater sense of place. LED Backlit TVs also benefit your eyes by raising room ambient light and reducing eye strain.

On the contrary, Full LED TV, also popularly for its LED display, uses an array of light-emitting diodes as pixels to display the images. Due to their intense brightness, the Full LED TVs are often used outdoors. Over time, it has been used in several transport vehicles for navigation and other display purposes.  

Comparison Table Between LED Backlit and Full LED TV 

Parameters of Comparison LED BacklitFull LED TV
Definition LED Backlit TVs have LEDs either on the sides or at the edges of the screen. Full LED TV has LEDs behind the screen; spreading out all over the display screen. 
DisplayIt has a thin display screen and better viewing angles. It has a thicker display screen. 
FeaturesIt has increased brightness and lesser power consumption.Full LED TV has a great brightness range, contrast, efficiency, and more power consumption. 
AdvantagesPixels that are illuminated from behind by the LED backlight appear richer and brighter; used mostly at homes. It has been used in several transport vehicles for navigation and other display purposes.  
Disadvantages It has complex drive circuits; thereby complicating the flow of current supply or direction of illumination to the screen.   It doesn’t have local dimming, thereby the screen appears less bright at a few spots.   

What is LED Backlit?

Displays equipped with LED Backlights get their backlighting from LEDs instead of cold cathode fluorescent tubes. LED Backlit TVs also benefit your eyes by raising room ambient light and reducing eye strain. Moreover, LED Backlit TVs have LEDs either on the sides or at the edges of the screen. 

LED Backlit TVs, therefore, accentuate the depth behind the subject and enhance the sense of place when viewing images. The earliest backup lamps appeared in the 1920s, before the invention of light-emitting diodes in 1962. Over time, manufacturers and suppliers have begun to advertise televisions using such a combination as an LED TV that incorporates both LED backlights and LCD panels. 

The features of LED Backlit TVs include a thin display screen and better viewing angles, clear perception of images, better contrast ratios, color gamut, dimming range, lighter, cooler, reliable, lower power consumer, and longer lifespan. Over and above, they have local dimming which can be used to increase or decrease the brightness on the screen. Due to its backlighting technologies, LED Backlit TVs have a longer lifespan, are environmentally friendly, have a flexible adjustment in luminous intensity, have low power consumption, are energy-efficient, and are less expensive than any other LED-based TVs. However, LED Backlit has difficulty in maintaining due to complex drive circuits; which thereby complicates the flow of current supply or direction of illumination to the screen. 

What is Full LED TV?

Full LED TVs, also known as LED televisions, display images using a grid of light-emitting diodes as pixels. Furthermore, Full LED TV is referred to as having LEDs behind the screen displays. Due to their intense brightness, the Full LED TVs are often used for outdoor purposes. Over time, it has been used in several transport vehicles for navigation and other display purposes.  

Originally, Hewlett-Packard (HP) developed and introduced the first practical LED display in 1968. Subsequently, in 1977. J.P. Mitchell became the first manufactured all-LED flat-panel TV. TVs with full LED technology are brighter, have good contrast, are efficient, and consume more power. On account of the LED from behind spreading uniformly throughout the screen, Full LED TV has a thicker display screen.

On the other hand, due to LED lighting over the screen, Full LED TVs consume more power. As a result, the intensity, brightness, and contrast of a Full LED TV are efficient. Besides, Full LED TV doesn’t use local dimming, thereby sometimes producing a low-quality display at certain spots on the screen. On the whole, due to the installment of the backlighting bulbs behind the screen; clear, high-quality images can be produced using full-array LEDs. 

Main Differences Between LED Backlit and Full LED TV

  • LED-backlit uses LEDs only at the edges or sides of the televisions. Meanwhile, Full LED TVs have LEDs installments behind them, which are spread out evenly over the entire screen of the television.
  • Full LED TVs have more lighting throughout the screen. Whereas, lightings are installed only at the edges of the TVs, eventually, having lesser lighting than the former. 
  • The LED Backlit TVs consume less power than Full LED TVs. 
  • The proportion of LEDs is more in Full LED TVs than the LED Backlit TVs.  
  • The intensity, brightness, and contrast of a Full LED TV are better than LED Backlit. 
  • The ability to control the brightness of the LED at certain spots on the display is a possible feature for LED Backlit TVs, but not for Full LED TVs. 
  • The displays of LED Backlit are thinner than the displays of Full LED TVs. 
  • Conclusion 

    In the abstract, the Light-Emission-Diodes play a major role in manufacturing television in these modern days. Due to their highly efficient LEDs, these TVs have been popular among various consumers around the globe. Besides, each category of LED TVs is differentiated based on the LEDs position, such as Full LED TV, has LEDs behind the screen, and LED Backlot has LEDs either at the edges or on the sides of the screen. 

    Furthermore, Full LED TVs produce clear, high-quality images because the LEDs are evenly distributed across the entire screen. LED Backlit TVs have local dimming which can be used to increase or decrease the brightness on the screen.
