Plasma and LCD TV systems

Since the demise of the CRT TV (Cathode Ray Tube) which was the standard television type for decades, three different types of technology have been used. These have resulted in the projector, plasma and LCD TV (Liquid Colour or Crystal Display). Today most consumers or buying the Plasma or LCD screens with the main considerations being price and screen size. Previously the Plasma technology had produced the largest screens with some being up to 100inches in size. However, advances in processing technology have meant that the size restrictions on LCD technology have now been largely removed and the biggest restriction is now in producing a large screen without defects. Picture sharpness for moving objects was also inferior for LCD screens but again advances in chipsets have improved this.

An example is Toshiba's new LCD TV Regza series which uses integrated processors to improve the sharpness of an image. Both types of screen are now being used, not just as TV's but as the hub of home entertainment systems with the introduction of high definition gaming consoles and DVD players. Integrated home theatre systems have also improved the sound quality removing the need for the consumer to buy a separate sound system. The biggest differences between the two types of screen are in weight, image brightness heat production and lifespan. In all areas the LCD is better. The light source within a LCD screen produces much less heat than its Plasma counterpart and also produces no radiation.
