A Quick Overview on LED TV’s – Features, Applications & Future

LED television is modern entertainment technology devices that often utilizes a series of light emitting diodes for representing a clear back light display of television. A true LED TV is one of those giant screens you usually see at outdoor stadiums, at grand prix events and rock venues. LED televisions are vigorous sets for high-definition picture delivery, they are large screens made up of thousands of extremely bright LED lights. The size of LED’s is mostly too big and full of chunks to use in TVs, but they are ideally suited as a light source for back lighting LCD crystals.



How does Light Emitting Diode (LED) Televisions Works?

In general, all latest televisions work through back-lit projection from a light source and onto the display screen. Older televisions use standard cathode ray tubes that are set in the back of the television and project light onto the screen, while LED televisions replace the tube with small light emitting diodes to present light.

Due to the small size and low power consumption of LEDs, LED-backlit TVs are far thinner than regular LCD sets and are also more energy efficient. They can also provide a wider color gamut, producing more vivid pictures.


LED televisions are much smaller than cathode ray tubes, allowing for lighter and thinner televisions to be constructed. LEDs are more practical light sources that permit better projection of darker colors than cathode ray tube television sets. LEDs shine light from behind the screen, illuminating the pixels to create an image instead of fluorescent tubes.

Types of LED Lighting Technology:

There are two primary forms of LED lighting technology that LED TVs can utilize: RGB LED lighting technology and edge-lit LED backlighting.


Edge LED lighting

This type of LED backlighting is referred to as edge lighting. In this method, edge-lit technology employs LEDs only around the edges of LED TV screens. Edge LED lighting televisions combine a series of LED backlights placed along the outside edges of the screen with a light-diffusing panel that spreads light from the outer edge of the set to the middle of the screen. The light is then dispersed across the screen.

The advantage of this method is that the LED/LCD TV can be made very thin. On the other hand, the disadvantage of edge lighting is that black levels are not as deep and the edge area of the screen has a tendency to be brighter than the center area of the screen.

Edge LED televisions do not allow the same robust contrast of RGB LED televisions, but they are built in very thin sets which are exceptionally lightweight and inexpensive.


Future of LED Television:

In the future, the most incredible technologies of LEDs can be enhanced from organic light emitting diodes-OLEDs. The organic substances and materials are used to create these devices to be more flexible, and also able to create bendable lights and displays.  OLEDs will cover the way for the next generation of TVs and smart phones.

I hope I have been successful in giving sufficient knowledge about the latest emerging technology in TV sets, i.e. LED TVs.  In the last paragraph, I have mentioned about the future of LED TVs and even given a hint.  So all you have to do is write in the comment section below, as to how OLEDs can be used in Television and how can that prove to be advantageous.
