DVD, LCD, HD, TV, LED: What do These Abbreviations Really Mean? LCD stands for liquid-crystal display, and describes the technology used by LCD televisions. The majority of TVs sold today have LCD screens. When you compare LCD TVs to other types of televisions, like CRTs and plasma screens, you’ll see that the LCD consumes much less energy. These TVs can be made very large and thin, so it’s easy to mount them on the wall. But, there is a limited viewing angle with LCD screens, so viewing distance and position is extremely important. LED. LED refers to the backlighting used in LCD televisions. LED stands for the type of display known as light ...

LED-LCD vs. Plasma A plasma TV is sometimes called an emissive display — the panel is actually self-lighting. The display consists of two transparent glass panels with a thin layer of pixels sandwiched in between. Each pixel is composed of three gas-filled cells or sub-pixels (one each for red, green and blue).
