Buying a Television is not like buying a smartphone which you will be upgrading regularly, as televisions will be used for years and as users, we want to get the best so that it does not get outdated in the near future. With the increase in the number of features and the types of TVs growing rapidly, it is becoming difficult to understand the differences and decide on which type of TV is the best for you.
So let’s look at the difference between the two most common types of television displays which are in the market at the moment – LED and LCD. One of the main differences of LED in comparison to the LCD is the source of light, which is similar to the displays seen in smartphones LCD vs LED displays.
Source of Light
In LCD displays, the source of light is from a series of fluorescent lamps which are present on the back of the screen. On top of these lamps are two layers of polarized glass which are joined together, the liquid crystals present in them help in passing or blocking the light, this helps in displaying the required color and picture on your LCD display.
On the other hand, the light source of the LED display is the LED’s themselves. The LED displays are also of two types depending on the placement of the LED’s on the display. LED backlit LCD TV and Edge LED backlit LCD TV, these two variants are a combination of LED’s and LCD Panel. In the LED backlit LCD panel, the LED’s are placed behind the display which is covered by diffusers, Polarisers, and LCD Panel over it. Whereas in the Edge LED backlit LCD TV uses LED’s placed around the edge of the LCD panel, which drastically decreases the thickness of the display. There is a Light Guide Plate which focuses light forward evenly for a brighter picture and further covered by diffusers to disperse light evenly across the display surface.
Coming to the Picture quality which is another important factor in deciding on a display, LED TV’s are said to be better because of the presence of individual LEDs which can be used to produce true black as they turn off the individual LEDs which increase the accuracy of color reproduction. LCD displays on the other hand, get a grayish tinge on Blacks because of the backlight which is always on and some amount of light passes through the crystals which are trying to show black.
Because of the better contrast and color accuracy the LED is always preferred for Picture quality compared to LCD. The viewing angles are similar and depend more on the glass panel placed over the display rather than the display themselves.
Power efficiency is more in the LED displays compared to the LCD display as the individual LEDs turn off when displaying black which conserves more power, compared to the fluorescent lamps which are always emitting light when the display is on and black color is obtained by the liquid crystals blocking the light coming from behind. This is the reason for more power being used up compared to the LED display.
Size and Thickness of the TV
If you are looking for compact, slim display without compromising on the quality, then LED display is the best choice. The LEDs can be placed in much lower places in comparison to the LCD display which requires fluorescent lamps at the back as the light source which takes up more space. So LEDs can maintain the thickness to a minimum even on increasing the size of the display, which is not possible with LCD displays.
If you have understood the differences properly, LED TV’s are improvised versions of LCD TV’s which consist of a different light source. Both the displays come with Liquid Crystal Display technology, with LCD having fluorescent lamps as light source and LED TV uses Light Emitting Diodes as light source. So the factors which you have to look at are pricing, LCD TVs are priced less compared to LED TV. Thickness of LED TVs is comparatively less than LCD TV. Power consumption of LED TV is lesser than LCD TV. Finally it is best to look at the TV’s personally to get an idea about the display and size of it before purchasing your new TV as the picture quality is almost similar in both the displays along with the viewing angles and resolution.
