Cathode Ray Tube
Light is produced when electrons emitted from the back of the tube strike the front of the screen,and light up the phosphor coating .
Plasma
Excitation of a gas by high voltage
LCD
Cold cathode florescent lamps, placed behind the LCD screen
LCD LED
White LED's placed behind the LCD screen
OLED
Light emitting diodes. Light is generated by passing current across a PN junction of specially doped material, which causes electrons to change valence level and emit light.

∙ 13y agoAN LCD television uses liquid crystals to generate an image. For each pixel on the screen, there are three crystals, one each for red, green and blue colors. Each crystal can be controlled to become clear or opaque and it is this ability of the crystal that builds a complete image. The crystals themselves do not generate light but simply allow light to pass through them when they are clear.
The light is generated behind the sheet of crystals. Until recently, the standard light source was based on fluorescent lamps. 2009 saw the introduction of LEDs as light sources. They are rather more efficient than conventional lighting and have also allowed the body of the television to be thinner than before.
Although the light source is important, it doesn't actually take part in the image generation. An LED LCD television is still an LCD television. These are not to be confused with a true LED television which uses three LEDs for every pixel. The LEDs glow so they provide the image generation as well as the light source itself.
