Since Plasma TV pixels produce their own light and colors without depending on any backlight source, the picture of the plasma TV is superior to that produced by an LCD LED TV. Each of the plasma TV pixels light up individually to varying colors depending on the electric charge applied to them. These cells glow when charged with electric voltages to produce different colors. The Plasma TV pixels are made up of gas filled cells, each containing a mixture of rare gases (neon and xenon). Plasma and LED TVs are both flat screen TVs, but they are very different and work with totally different technologies. So the flat screen of both an LCD and LED TV is the same, it is only the type of projection lamps behind the LCD screen what makes an LED TV and LCD TV different.More from our dedicated page on LCD LED TV What is Plasma TV and how it works In an LCD TV the backlight bulbs are CCFL type (Cold Cathode Fluorescent Light) and in an LED TV, the backlight is from LED bulbs (Light Emitting Diode). What makes an LCD TV and an LED TV different is the backlighting bulbs in the TV. In both an LCD and LED TV, the main screen on which the picture is formed is an LCD screen. When the liquid crystal elements in the LCD panel are charged with electricity using individual transistors for each pixel, the LCD crystals allow a certain amount of light to pass through the LCD screen, the backlight being produced by either of two sources, by a CCFL (Cold Cathode Fluorescent light) in an LCD TV or by LED (light emitting diode) bulbs in an LED TV. LCD TVs are Flat Screen TV’s making use of LCD (Liquid Crystal Display) screens, which have millions of liquid crystals, sandwiched between two glass panels. How these flat screen TVs work are explained below How LCD LED TV works There are 3 types of flat screen TVs: LCD / LED TVs, Plasma TVs and OLED TVs. Modern TVs have wide flat screens with 16:9 aspect ratio. These were black and white TVs, color Tube TVs were commercially available only from early 1950s. In 1934 'Telefunken', a German Company was the first to produce commercially available Televisions using Cathode Ray Tubes. The first TVs to be used were all Tube TVs. Watching a movie on the small 4:3 screens of a tube television is a far cry from watching on a modern wide 16:9 flat screen TV The CRT tube TV disadvantages were that tube TVs larger than 29 inch was not available and they were bulky and heavy. Here is a picture of the old Tube TVs which many kids now may not even remember ever having seen one. It is still possible to buy Tube TVs, but most of the big manufacturers of TVs have stopped producing CRT tube TVs. The world's first TV transmissions were carried out in USA in 1936 and Tube TVs were used to watch those early TV programs. The Cathode Ray Tube (CRT) TV or simply Tube TVs was the first generation of TVs. These different types of TVs are explained below. There are four different kinds of TV screens available today, these are 'CRT' or 'Cathode Ray Tube' 'LCD' or Liquid Crystal Display (LED TV is an LCD TV with LED backlight) 'Plasma' TV and the newest 'OLED' or 'Organic Light Emitting Diode' TV. How different types of TVs work, how many types of flat screen TVs are there?
