LED Technology

LED technology is the most recent technology in TV industry. LED stands for light emitting diode and it emits electronic light which in result amazing display quality.
LED technology was first invented in 1920 by Russia, but it took quite long when Americans first launched practical electric device using LED technology and in 1962.

Note: This article was published back in 2009 and now I am updating it in Year 2017. LCD's are gone for good. Now is the time for 4K ultra HD TV. Click for LG 4k TV for more information.

Devices invented before produced low intensity red light, but latest and sophisticated LED technology manages to emit visible ultraviolet light, infrared wavelength with very high picture quality and brightness. LED technology is based on semi-conductor diode, when this diode gets active or switched on; energy is released in form of light when electrons are combined with holes. This effect of emitting light is called electroluminescence. LED’s normally are small in areas; optical components are shaped and integrated in such a way that its radiation patterns and reflections remain consistent.

LED offers many advantages over previous display quality devices technologies. Benefits like lower power consumption, smaller size, improve lifetime performance, fast switching etc. On the other hand LED comes with some negative points, LED technology is a bit expensive comparing with other light source technologies, and they also require exact electric power and heat management system.

There are many LED applications available today, as mentioned before LED technology based devices consume very low energy, that’s why it is a good replacement for traditional light sources which are used for general lighting. Small size of LED also enables new text and video displays devices.
