Kuna inventor nataka kununua ambayo huwa inatumika kuwasha umeme wakati unapokatika, Sasa nimeambiwa kuwa inauwezo wa kuwasha Tv yoyote isipokuwa ya plasma kwa kuwa inakula sana umeme, Naomba wataalam wa JF watujuze juu ya hizi tv za plasma

Yeah - They are poorly calibrated!

Research shows that "... Plasma TVs use more power than LCD TVs....., on average, roughly two to three times more electricity to produce an image of the same brightness as LCD ..."

Hizi Plasm TV ndiyo zipi? Hizi tulizozizoea na tulizonazo home?
 
yes absolutely true that plasma consumes more electricity.the simple answer is tht,kila pixel kwenye plasma ina kuwa na bulb yake tofauti kwa ajili ya kuproduce colour,and hence image,while for lcd au led tv,kuna kuwa na central bulb ambayo inamulika hiyo screen and hence kupata image.kuna led n lcd za sasa zina kuwa na intelligent sensor,ambayo ina sense mwanga wa chumba na ku regulate electricity according to the liting of the room,and hence also saving electricity.if the room is well lit,thn less consumption of electricity.kuna reason mengi,lakin hiyo ya bulb difference is the major.
 
The power consumption of an LCD tv is virtually constant because they have a back light that is on all of the time. The back light can be manually adjusted but uses less power on a low setting and more power on a high setting. The modulation of the LCD tvs screen pixels takes very little power.
However Plasma tvs charge a gas to a plasma to generate light. The more light that is required the more often this is done. So it's usual for plasma tvs to require more energy on an image with high levels of brightness, and less energy on low brightness scenes. So the power consumption varies.
The energy requirements that are quoted for Plasma tvs are for full brightness settings. The effect of this is that lcd tvs seem to use less power than plasma tvs. But the power consumption of a plasma tv varies depending on the amount of dark and bright areas on the displayed image. Studies have found that when the viewed programs are mainly dark or on movies the amount of power consumed for plasma tvs will be lower than an lcd tv. However when the viewed programs are sports and cartoons the power consumption for plasma tvs is greater than on lcd tvs. When varied programs are viewed the power consumption is similar for LCD tvs and Plasma tvs. Future plasma tvs are going to consume less than half the amount power consumed at present.
 
halafu pia zina expire, upo hapo?


zina expire baada ya miaka 6/7 ukitumia kwa masaa 24hrs .......can u do that??btw unaweza kukaa na tv miaka 10??if yes plasma/lcd is not for u zinabadilika kila mwezi/mwaka.

hata PLASMA ZINA INTELLIGENT SENSOR.......

Now, the latest trend in TVs could catapult it to a billion-dollar business: Frameless flat-screens that could be mistaken for chic glass artwork on a living-room wall.
Because Gorilla is very hard to break, dent or scratch, Corning is betting it will be the glass of choice as TV-set manufacturers dispense with protective rims or bezels for their sets, in search of an elegant look.
Gorilla is two to three times stronger than chemically strengthened versions of ordinary soda-lime glass, even when just half as thick, company scientists say. Its strength also means Gorilla can be thinner than a dime, saving on weight and shipping costs.
Corning is in talks with Asian manufacturers to bring Gorilla to the TV market in early 2011 and expects to land its first deal this fall. With production going full-tilt in Harrodsburg, Ky., it is converting part of a second factory in Shizuoka, Japan, to fill a potential burst of orders by year-end.
"That'll tell you something about our confidence in this," said Corning President Peter Volanakis.
