Technology is getting better and the acronyms are getting tougher. We have all heard about LCD TV, LED TV and OLED TV. But how many of us are really aware of the clear differences between each of them? Well, I am sure not many us know anything in depth about it. So here we are with clear differences between LED TV and LCD TV.
Read through to know more.
An LED TV is nothing but an LCD TV -
Yes! You read it right. An LED TV is nothing but a 'LED-backlit LCD TV'. This means that LED TV is a subset of LCD TV. On the other hand, LCD stands for 'Liquid crystal display' and technically both LCD and LED are liquid crystal displays. To be more precise, both LED TV and LCD TV to have 2 layers of polarized glass via which the liquid crystals block and pass light.
A LED TV uses Light Emitting Diodes fore backlighting purpose and thus, uses less power and offers a brighter display with better contrast. It also comes with the thinner panel and dissipates lesser heat when compared to conventional LCD TV which uses CCFLs (Cold Cathode Fluorescent Lamps).
Picture quality - When it comes to picture quality, it is pretty hard to decide about which delivers high picture quality. That is because both the TVs use the same kind of screen to deliver pictures. A high-end LCD TV can deliver a better quality when compared to low end LED TV. However, if you compare high-end models of both LED and LCD TV, the picture quality will be almost similar.
Different types of LED TVs and LCD TVs -
There are 3 different types of LED TVs and LCD TVs.
The different types of LED TVs include Edge LEDs, Dynamic RGB LEDs and Full-array LEDs.Edge LEDs -
These are the most common and positioned around the frame of the screen. They use a special diffusion section to spread the light evenly behind the screen.Dynamic RGB LEDs -
This type of LED TV uses a different backlighting technique which allows specific areas on the screen to be dimmed.Full-array LEDs -
This type of LED TVs has a set of LEDs arranged behind the screen. But, these LEDs are ineffective in dimming or brightening individually.
The different types of LCD TVs include Flat Screen LCDs, Front projection LCDs and Rear projection LCDs.Flat Screen LCDs -
These are super sleek and are just about an inch or two thick. They are popular of all and are also the expensive ones considering its flexibility to wall mount or to place it on a surface.Front Projection LCDs -
These are nothing but projectors installed in a box in the room. It basically projects an image on to the flat screen mounted on the wall as big as 300 inches.Rear Projection LCDs -
These are mostly wide, heavy and are available in big sizes (60 inches or more). In this type of TV, the image is sent from the rear of the TV to the front screen.
Colour and Contrast -
An LED TV is known to deliver more colours when compared to an LCD TV. Especially the RGB-LED backlighting delivers truer colours of whites and blacks. RGB Dynamic LEDs get higher dynamic contrast ratio with small detailing on small bright objects on a dark background.
An LED TV is known to be the most popular TV and they are also the ones which come in a huge range of prices. On an average, LED TVs are actually priced higher than the LCD TVs. This is because of the traditional CCFLs used for backlighting in the LCD TVs, unlike the LED TVs.
So, the next time when someone asks you what a LED TV and LCD TV stands for. You know what to answer!
