What is LED TV?

LED televisions are now becoming a common appliance that is obtainable to buy on the market, but let's have a glance at what an LED TV actually is.

Fundamentally an LED TV is a flat screen TV where the images are transmitted onto the screen by light emitting diodes. Because these diodes are reactive to light, they can be made to suit larger screen sizes. The range of light & color led screens can show are different to the older CRT type of TV where electrons were fired at the screen to produce the picture.

Light emitting diodes are tiny carriers of electricity that will light up when electric current is passed through because they are made in a pure type of compound where all the atoms fuse together perfectly & electricity is passed through without any loss due to impurities associated with other electrical carrying compounds. Because of this, screens can be made thinner & run on greatly reduced power consumption.

These TVs are built in such a way that the contrast ranges from absolute black when the unit is switched on, to absolute pure white when the unit is working; this allows for a great range of color to be displayed on the screen that looks more vibrant & natural. Unlike the older televisions with a tube, LED TVs do not use mercury in the production technique but because arsenic is a compound that is used, this will present its own issues when it comes to disposing of it; so keep in mind this when asking "what is an LED TV"?

More recently, a newer type of LED is being manufactured that allows for the creation of a 75 inch screen; these types of LED will shape the future of TV expertise for years to come. In places all around the globe where people collect to watch major events, giant screens are being used to permit people to feel like they are at the middle of the action. Concerts, historical events & major sporting events are now broadcast to lots of people using the expertise of LED TV. South Korea is speedy emerging as of the largest producers of flat screen televisions. As their popularity increases, newer high-definition screens are now coming onto the market. Whilst the cost of these screens at the moment are prohibitively high, ways are being sought to integrate new screen coverings that are cheaper to produce & thus the reduction in costs will finally be passed onto the consumer.

Over time, as increasingly broadcasting companies turn over to digital broadcasting, LED TVs will replace the CRT screens & the general public will have in their home; whether it will be a giant screen or a medium size will depend largely on the style of the room. Some can be wall mounted whilst others are free standing models which permit for greater flexibility in placement. In conclusion a Led TV is a flat bed of light emitting diodes that can be powered individually or from the edge to deliver crystal clear picture quality seldom before thought feasible.
