Buying a new TV can be really confusing in India with every brand claiming to offer the best LED in the market in every price range. And if you are buying a new TV online things get more difficult. It can get tricky to understand the terms LED, LCD, OLED and QLED. So, here are the basic differences among these display terms.
LED and OLED
Talking simply, there are two kinds of TV that you can buy in 2020–LED and OLED. LED TVs are affordable while OLED TVs are the most expensive. So, TVs under Rs 1 lakh are mostly LED. So, what is LED?
The affordable LED TVs that you get to see are mostly LED-LCD. This means there are LEDs behind the screen that can be individually brightened or dimmed.
What is an LED-LCD TV?
The affordable LED TVs that you get to see are mostly LED-LCD. This means there are LEDs behind the screen that can be individually brightened or dimmed. Most mid-range TVs come with full-array backlight, especially the models that have Ultra HD resolution. The picture quality is just good enough to get the job done.
If your TV model doesn’t have a full-array panel then it will most likely have edge lighting or direct lighting. Now, direct lightning is of the lowest quality. There’s no local dimming with little depth and everything looks greyish. On the other hand, edge lighting is where the LEDs are placed on the sides. It offers better dimming than direct LED panels but not as good as full-array panels.

What is Quantum dots and how is it different from QLED and OLED
After LED-LCD, another LCD display technology is quantum dots. It offers a wide range of colours and is brighter. Quantum dots help in better colour reproduction and also offer deeper blacks. However, do not confuse quantum dots with QLED. QLED TV can be simply called LED backlit with quantum-dot LCD TVs. And this is not the same OLED. Infact, QLED is between LCD and OLED. OLED TVs offer the deepest blacks and best contrast.
OLED TVs offer pixel level lighting control and there is a layer of organic LEDs that offer the best colours and more importantly contrast ratio.
Are QLED TVs better than OLED TVs?
QLED TVs are better than LCD but are not as good as OLED TVs. Quantum dots help in better colour reproduction and also offer deeper blacks. However, do not confuse quantum dots with QLED. QLED TV can be simply called LED backlit with quantum-dot LCD TVs. And this is not the same OLED. Infact, QLED is between LCD and OLED. OLED TVs offer the deepest blacks and best contrast. So, it goes without saying OLED is the best but it’s expensive too.
