LED’s or light emitting diodes, are electronic components that exhibit a certain color based on a certain level of current applied to the diode. Higher current produces darker colors, and vice versa, in accordance with the light spectrum. LED’s have been implemented in electronics for decades, and the recent developments in LED technology have brought us such luxury items as HDTV and other LED-based toys and tools.
High Definition Television is a recent development in television broadcast and viewing where a digital signal is broadcast giving a higher resolution of the picture on the screen than what a standard television can. The picture tends to be clearer and more precise in definition that traditional television by being displayed on one of two major kinds of screens. One is plasma TV technology. The other is LCD (liquid crystal display) technology.
LED technology comes into play more prominently in LCD TV as backlighting for those screens. The liquid crystal display screen, the same technology as a digital watch, is dark by its nature, and to be able to see a scene on a television screen, LED technology is used to brighten the screen from behind in order to make the picture visible to the viewer.
The backlighting ability of LED technology was first implemented in the early 1990’s in Personal Digital Assistants and hand-held video games and cell phone screens. The technology has spread across many electronic products from MP3 players to portable DVD players.
LED’s are large by nature, and the development of a full-screen LED TV is currently under design in the industry, particularly in the pocket size TV market. Many TVs overseas that fall into the pocket TV category are sold in LCD format, and, again, are backlit by LED technology. The development of TVs that use LED’s to form the main picture is being developed overseas, and in an experimental manner in the U.S.
