TV Display Technology: LCD


LCD stands for Liquid Crystal Display. It is a particular flat panel that either allows or blocks the passage of light. In this technology, liquid crystal technology is used. This technology combines liquid crystals and polarizers to create images on the screen.

Generally, LCD TVs have three polarized glass panels known as substrates. It contains liquid crystals in between them. These panels are in red, blue, and green colours. Whenever electric current passes through these substances, the crystals rotate and align to let the light pass through the other substrate. In this way, we can see colours and images.


  • High resolution
  • Superb colour
  • Lack of screen burn-in
  • Energy efficiency

Pros & Cons

Improved picture due to the use of backlight LEDsLimited viewing angle
AffordableNot so impressive reproduction of black images
Multi-functional capabilityRestricted brightness
Energy-efficient as compared to older bulb lit and plasma screensCan suffer from screen lag & blur

TV Display Technology: LED


Usually, most people think that LED displays are a new format, but the truth is that they have been around for a long time. LED stands for light-emitting diode. LED TVs are an updated version of the LCD generation. When it comes to technology, both LED, and LCD TVs use the same one.

The only difference is that the LCD TVs screen gets illuminated by a fluorescent bulb, whereas several LEDs lights the LED screen.

These TVs can be divided into two subcategories:

  1. Edge-lit LEDs
  2. Direct back-lit LEDs.

In edge-lit TVs, TV screens are lit from the outer edges, whereas direct back-lit LED TV screens are backlit by LEDs located directly behind the LED screen.


  • Narrower & efficient
  • Less energy-intensive
  • Improved viewing angle

Pros & Cons

Versatile & robustDifficult to mount on the wall
Improved viewing angle & brightness

TV Display Technology: QLED


QLED stands for Quantum Light Emitting Diode. Nowadays, QLED TVs are one of the most popular in the market. It is one of the variants of LED TV display technology that rely on a backlight. Whenever the LED backlight hits the quantum dots, its microscopic molecules emit different coloured lights.


  • QLED screens are last longer, larger, and not susceptible to burn-in.
  • The price difference between QLED and OLED is QLED are more affordable than OLED.
  • 50 to 100 times brighter than LCDs.
  • It is 2X energy-efficient than OLED TVs.
BrighterLong-term durability unknown
bigger and smaller both sizes are available 
Not susceptible to burn-in 
Superior contrast ratio 
Wider viewing angles 

TV Display Technology: OLED


Featuring next on the list is OLED. It stands for Organic Light Emitting Diode. If you search for the highest quality TV display technology, OLED is the perfect pick. This technology uses organic materials like carbon to produce light when an electric current directly supplies it.

The impressive thing about OLED TV is that it does not need a backlight to illuminate the screen area like LCD and QLED. Therefore, it can be very thin and flexible. OLED TVs produce less heat and consume less power than LCDs and LEDs.


  • Thicker and sleeker
  • Excellent picture quality and colour display
  • Requires no substrates
No screen lag or blurExpensive to manufacture
Richer colours & true blacks as compared to any other TV display or monitorCostly for the consumer
Easy to produceIts pixels burn easily
Wide viewing anglesQLED loses brightness much faster than other transparent technologies

TV Display Technology: Nano Cell

Nano cell

The next on the list is Nano Cell. It is a type of LCD/LED TV from LG. In Nano Cell technology, nanoparticles are used at individual pixels. They absorb unwanted light and enhance the primary red, green, and blue colours on the screen.

As a result, you will experience deeper colours, sharper tones, and an overall wider colour palette that creates natural colours and sharper pictures at all viewing angles.


  • No burn-in issues
  • The display type is LED backlight
  • Colour accuracy is outstanding
  • Viewing angle wide
Improved colour reproduction from regularYou will not get perfect blacks
Excellent for HDR content because of higher pick brightness as compared to OLED TVsSlightly thicker and heavier than OLED TVs

Now, let’s have a quick comparison review of all these technologies


  • QLED picture quality usually varies more than OLED
  • It is brighter as compared to OLED
  • OLED has improved contrast and black level
  • OLED has better viewing angles and uniformity as compared to QLED.
  • When it comes to resolution, colour, video processing, and other image quality, all these factors are the same.

OLED vs Nano Cell

OLED vs Nano cell
  • OLED has a self-emitting pixels display type whereas Nano Cell has an LED backlight display type.
  • It offers a very wide viewing angle, whereas Nano Cell offers wide angles.
  • It costs more than Nano Cell
  • OLED’s screen thickness is ultra-thin, less than 4mm, whereas Nano Cell screen thickness is between 35mm and 45mm.
  • OLED has a very low response time as compared to Nano Cell.
  • Both technologies offer the same colour accuracy.


  • LED LCD screens are brighter than OLED.
  • OLED struggles with the colour volume, whereas LED LCD favours it.
  • In all three, the lightning unit is the Pixel unit.
  • The structure of LED LCD is quite complex, whereas OLED has a simple structure.
  • In LED LCD backlight unit is CCFL, LED whereas, in OLED, it is self-emissive.
