James P Mitchell developed the first trial product of the LED

The term LED is an acronym for light-emitting diode and is a significant technique which was implemented in the use of flat screen television. The light emitting diode is a semi-conductor diode which emits a narrower light spectrum when electricity is passed through it. The semi-conducting material used may be visible, near-ultraviolet or infrared and it the composition of this semi-conductor material which determines the color of the light rays which are emitted. The pattern of radiation of the light-emitting diodes is determined by the addition of extra optics that is added to this chip. It is important to note here that the LEDs are considered good options as power-saving devices as they emit much more light per watt than normal luminous bulbs and are therefore are extremely useful as an energy–saving device. The LEDs has strong natural life and therefore they are popularly used for various kinds of functioning and because of being formed of solid state components they are not prone to any sort of initial damage as a result of electric shocks.

It was in early 1977 that James. P. Mitchell developed the first trial product of the flat panel LED television screen and it was constituted by MV50 LEDs and the TTL or the transistor transistor logic which referred to the then newly developed memory addressing circuit technology. This innovation was greatly appreciated by organizations of great renown like General Motors Corporation and NASA and in 1978 this prototype was displayed for the first time in the Engineering Exposition. This early example of the flat panel LED television screen comprised of red monochromes and it was only in the 1990s that the cheaper blue LEDs came into being for use in these purposes. this was followed by the emergence of other color schemes as well and it was prevalently used in as billboards and in stadiums as high resolution displays.
