Television technology for the past 75 years has been based on the technology of CRT or cathode-ray-tube. Thermosculpt Pro In it there are guns that fire beams of electrons, which are particles that are negatively charged inside a tube, made of glass. These electrons cause excitement in phosphor atoms located at the screen end or the end of the tube that is wide. As a result the phosphor atoms gets lighted up. The phosphor coating being lighted up on different areas with various colours with dissimilar intensities produces the image on the screen. The images are sharp and vibrant but the sets are bulky. Thermosculpt Pro Thus a big screen will result in a television set that will take up a good size of the room! With necessity being the mother of invention, this difficulty has led to the popping up of a new technology leading to plasma flat panels for display. These sets have wide screen but are only a few inches thick.A video signal lights up thousands of dots inside the monitor or television. These dots are known as pixels having highly energized electron beams. Thermosculpt Pro Usually pixels have three colours - blue, red and green. These are evenly spread out across the screen. Combining these basic colours in different proportions produces the entire colour show. The fundamental idea of the plasma unit is to light up minute coloured lights that are fluorescent to create the image. Each pixel comprises of three of these lights - red, green and blue. Similar to the CRT, the plasma television alters the intensity of the various lights to bring about the effect of the full spectrum of colours.
