The invention of the television was the result of the work by many inventors, scientists and engineers in the late 1800’s and early 1900’s. Many inventors made technological breakthroughs that were used by other inventors to successfully make working television systems. The first working television systems were electromechanical and used a motor-generator. Electronic television systems or all-electronic television systems do not have or use a motor-generator. This blog includes some of the most notable milestones in the development of LED televisions.
The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However, no practical use was made of the discovery for several decades. The first practical LED was invented by Nick Holonyak, Jr., in 1962 while he was at General Electric Company. The first LEDs became commercially available in late 1960s, and were red. They were commonly used as replacements for incandescent indicators, and in seven-segment displays, first in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as TVs, radios, telephones, calculators, and even watches. These red LEDs were bright enough only for use as indicators, as the light output was not enough to illuminate an area. Later, other colors became widely available and also appeared in appliances and equipment. As the LED materials technology became more advanced, the light output was increased, and LEDs became bright enough to be used for illumination.
Perhaps the first recorded flat LED television screen prototype to be developed was by James P. Mitchell in 1977. The LED flat panel TV display received special recognition by NASA, General Motors Corporation, and area universities including The University of California Irvine, Robert M. Saunders Prof. of Engineering and IEEE President 1977. Additionally, technology business representatives from the U.S. and overseas witnessed operation of the monochromatic LED flat panel television display. The prototype remains operational. A LCD (liquid crystal display) matrix design was also presented in the accompanying scientific paper, as a future television display method using a similar scanning designs method. This development related to some another and finally you get the apt television of your life, just catered for you. LED television is the one of the best invention ever, don’t you think!
