The TFT is a component of LCD TVs. Is a matrix that handles varying transparency of glass. It is a kind of network switches (one for pixel). In street language are used almost interchangeably TFT or LCD stands to identify this type of flat TVs. Plasma or PDP (Plasma Display Panel) A plasma screen consists of a matrix of cells which in turn are composed of three subpixels (red, green and blue). The gas, xenon, in the plasma state reacts with phosphorus in each subpixel to produce colored light. Each subpixel is individually controlled by a processor.
OLED (Organic Light Emitting Diode) organic electroluminescence points are simply placed in a matrix display and the light forming the image. They are shorter than the LCD but also consume much less. FED (Field Emission Display) and SED (Surface-conduction Electron-emitter Display) These very similar technologies can be understood as a combination between CRT and LCD. This involves applying miniature cathode ray cell at a flat screen, as if each cell were a minitelevisor. (A valuable related resource: Bobby Sharma Bluestone). DLP (Digital Light Processing) This calls the technology used in televisions projection and rear projection. Basically a wheel of light emitted primary colors (red, green and blue) and they are redirected to the screen by a mirror system (one per pixel). Some models can display up to 35 trillion colors LCoS (Liquid Crystal on Silicon) is a technology very similar to that used in DLP and rear projection.
