Liquid crystal and plasma maintain the sky of flat TV jointly, bad of what actor what, without final conclusion, the choice of consumer also is decide according to particular case. But a lot of consumer do not understand both very, we introduce the relevant index of a few liquid crystal and plasma TV below, the hope increases consumer to be in with this the knowledge of this respect.
Colour behaves force
The chromatic implementation of plasma and CRT TV are same, it is through red, green, La San lubricious fluorescent material suffers arouse light to come true, so strength of its colour show can achieve NTSC to make CRT color television (abbreviation NTSC) level. The color of liquid crystal is in a poor light by white through red, green, La San lubricious filter comes true, the range of best color expression that uses CCFL to be in a poor light the lamp can be achieved at present is the NTSC of 75% , so of liquid crystal colourful degree poorer.
Power comsumption problem
Power comsumption is exorbitant it is the place that plasma gets a person to denounce all the time, industry is having indefatigable effort for this, deserve to compare through coming in recipe of discharge room construction, gas for years, of the respect such as electrode appearance and drive circuit improve, the glow efficiency of plasma already rose to 1.8lm/W of before two years from inchoate 1.2lm/W, arrive then present 2.5lm/W, make 42 inches plasma power comsumption fell from 400 much tile 200 much tile.
The efficiency of fluorescent tube glow of liquid crystal TV is as high as 30~100lm/W, the CCFL of TV of big screen liquid crystal is in a poor light the glow efficiency of tube can accomplish 50~60lm/W, be plasma 20 multiple, but after assembling indication screen, be in a poor light utilization rate has 5% only about always, far the province report in imagining.
Life problem
The life index of the liquid crystal that sees normally and plasma is to show brightness falls the time when the half, not be mean time between failure. Because inchoate plasma uses the fluorescent material on CRT, the ultraviolet radiation that to plasma discharge produces bears capacity is insufficient, ageing is faster, make life insufficient. But special fluorescent material has realized the plasma of new generation long life, tall brightness commercial, make its life raised one times above.
The cycle that the television updates is general and longer, a lot of consumer are to use 10 years continuously, and at present the television uses be in a poor light tube life already amounted to 50 thousand ～ 60 thousand hours, use a requirement for a long time of completely OK and contented consumer.
