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. It can get tricky to understand the terms LED, LCD, OLED and QLED. And if you are relying on the shopkeeper to understand the difference among these jargons then most likely you may end up more confused. So, here are the basic differences among these display terms.
LCD and OLED
Talking simply, there are two kinds of TV that you can buy in 2020–LCD and OLED. LCD TVs are affordable while OLED TVs are the most expensive. So, TVs under Rs 1 lakh are mostly LCD. 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. Most mid-range TVs come with full-array backlight, especially the models that have Ultra HD resolution. Now, full-array LED backlight TV gets the job done but the issue is these TV can’t portray darker scenes and shadows properly. As it is backlit, the pixels can’t ever become completely black.
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.
If you are looking for a budget TV, try to opt for a full-array LED panel to get better contrast and colours.
Quantum dots vs QLED vs 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.
