I expect people that works in the Electronic store to know their TV hardware information. A few places I asked about their LCD TV if it’s LED, and I got an answer that it’s not LED, it’s LCD. All LED Tv’s are LCD. A few times I had to let them know, LED is the backlighting technology that has been out since 2004 by Sony in their Bravia TV lines. Of course there are EDGE LED Lit or Full Back Body LED Lit. EDGE LED Lit is cheaper.
Sure it’s marketing strategy by Samsung to call it LED TV, which is a smart move, it got people confused, but it does sound good. Who wants an old technology when they can get an LED TV?
A flat panel LCD TV set that uses LEDs (light emitting diodes) for its backlight source rather than the traditional fluorescent lamps (see CCFL). Smaller, more power efficient and having a greater optical range than the fluorescents, LEDs produce deeper blacks and more saturated color. Sony was the first to sell an LED TV in 2005.
Although the TV is really an LCD, and the LEDs are secondary components, the industry calls them LED TVs to avoid more drawn-out monikers such as “LED backlit TV” or “LED-based LCD TV.”
White LEDs are less costly, while red, green and blue (RGB) LEDs provide a richer color gamut.
There are two LED TV architectures. There can be a full array of LEDs that cover the entire back of the screen, or LEDs can beam light in from the edge. The full array provides uniform light across the screen; however, the case is thicker. In addition, groups of LEDs can be selectively dimmed based on the image in those areas at that moment, although not all full arrays do that.
Edge-lit LED TVs can be housed in ultra-thin cases but have a tendency to be brighter at the edges than at the center. See LED, LCD, flat panel TV and Dolby HDR.
