LCD TV
Thinking on changing your CRT tv to the new style of LCD tv but fearing that it would consume more electricty than CRT tv ? Fear not , i got your answers here
Does digital TV use more electricity than analogue TV?
- Digital TVs do not use any more energy than analogue TVs.
- However, larger screens will need more electricity than smaller screens, so if you are trading up to a bigger TV it will probably use more energy.
- There is no significant difference in the energy consumption of different TV technologies: a 32″ CRT (cathode-ray tube) or current flatscreen model will consume much the same energy
What makes LCD TV better than CRT
stands for liquid crystal display. A TV LCD consists of primarily two transparent, glass-like materials, which are polarized, and �glued� together. One of these plates is coated with a polymer that holds the individual liquid crystals. Electric current is then passed through individual crystals. This allows the crystals to pass or block light to create images. Unlike plasma TVs, an external light source is needed.
- flat, flat screen means less space consumption. it’s also less weight than normal crt’s tv.
- wide screen. most lcd tv comes in 16:9 while crt tv only came at 4:3 ratio. Widescreen tv is best use for watching sports, dvd, playing games and high definition TV. The wider, the better.
- CRT screens curve. LCD/ plasma TV models are perfectly flat. The benefit to this is that distortion is eliminated.
- Lcd tv do not suffer from �hot spots.� Hot spots are spots of uneven brightness
- If you look closely at a CRT TV, you will notice lines on the screen. That is because conventional TVs use an electron beam to scan the picture tube from top. LCD/ plasma TVs do not have lines because they use pixels to generate color.
- Price wise , lcd tv is more expensive than CRT but it comes with better performance and quality plus less space consumption
