Plasma vs LCD
size matters when it comes to making a choice. lcd is at its optimum performance up to and including 37", whilst plasma offers optimum performance at 42" and above.
the energy consumption of both is actually about the same in normal operating conditions.
the life span for both is dependent on viewing habits, but if both are watched for the same duration, one would expect the life span to be approximately the same, 60 000 hours, roughly twice the life span of older crt technology.
for natural daylight and bright conditions lcd is the perfect solution.
in larger rooms or rooms where the lighting is less harsh, plasma will deliver the highest picture performance for movies and sports as only plasma can deliver the subtle detail in dark scenes with rich blacks and vivid colour reproduction.
the use of backlight technology to illuminate lcd panels limits their viewing angle. because light is created on the surface of a plasma screen, picture quality is equally good from any angle of viewing.
Plasma
The phosphors in a plasma display give off colored light when they are excited. Every pixel is made up of three separate subpixel cells, each with different colored phosphors. One subpixel has a red light phosphor, one subpixel has a green light phosphor and one subpixel has a blue light phosphor. These colors blend together to create the overall color of the pixel.
By varying the pulses of current flowing through the different cells, the control system can increase or decrease the intensity of each subpixel colour to create hundreds of different combinations of red, green and blue. In this way, the control system can produce colours across the entire spectrum.
The main advantage of plasma display technology is that you can produce a very wide screen using extremely thin materials. And because each pixel is lit individually, the image is very bright and looks good from almost every angle. The image quality isn't quite up to the standards of the best cathode ray tube sets, but it certainly meets most people's expectations.
PVR
personal video recorders also known as digital video recorders.
it is an alternative to a set top box and vcr or dvd recorder. it allows one to access and record digital programmes on to an internal hard drive.
