What's the difference between plasma display and liquid crystal display?

the enterprises producing liquid crystal TV often claim to be superior to plasma TV in terms of definition, and claim that the highest physical resolution of plasma TV is less than 1024 × 1024, and almost all LCD TVs can reach 1024 × 768, the highest has reached 1920 × 1080.
in fact.
most plasma TVs on the market have a physical resolution of 852 × 480, only a few plasma TVs have a physical resolution of 1024 × 768.

but the definition of flat panel TV is not only determined by the physical resolution of the screen.
the circuit also directly affects the definition of high-definition signal processing, It's not enough to judge from the physical resolution of the screen.
so.
it's not scientific for LCD TV manufacturers to attack plasma TV from the physical resolution of the screen.

about the perspective
no matter how LCD TV defends.
plasma TV is better than LCD TV in terms of perspective, of course, plasma TV is not "no perspective problem." The TV used in bedrooms.
few people watch TV at an angle of more than 120 degrees, so from this point of view, there is no need for both sides to attack the angle of view.

about response speed
response speed used to be the weakness of LCD TV.
although there have been great improvements in technology recently, But sometimes they are attacked by the enterprises that produce plasma TV.
some enterprises claim that their LCD TV response time has been reduced to 8 ms, but in fact, most of the LCD TVs sold in the market have a response time of about 12 Ms.
some enterprises claim that their LCD TV response time has been reduced to 8 msEven if the LCD TV has claimed that the response time is reduced to 8 ms.
when playing fast-moving images, there is still a tailing phenomenon, because the 8 ms response time claimed by the enterprise is calculated when playing still images.

for a fast-moving black image or white image,
LCD TV has a slight tailing phenomenon, but this does not mean that the response time of LCD TV is low, Plasma TV is perfect in this respect. For fast-moving white objects, plasma TV will also have a slight tailing phenomenon, only when the fast-moving objects change to black, There will be no more trailing phenomenon.

about burn.
plasma TV is better than LCD TV in processing moving images.
but when the still image appears in the same position of plasma screen for a long time, burn phenomenon may appear.
when plasma TV appears burn phenomenon.
when switching on or off, the image that has been played for a long time will appear vaguely on the screen, It seems to be printed on the screen, and this has become the target for some LCD TV manufacturers to attack plasma TV.

about contrast
if we only look at the contrast figures marked on plasma TV and LCD TV by enterprises.
LCD TV is far inferior to plasma TV, But it can't be said that plasma TV is better than LCD TV.
this is because plasma TV and LCD TV adopt different contrast measurement methods.
even the measurement methods adopted by each enterprise are different. Of course, the data marked on their products will be very different.
plasma TV mostly adopts all white and all black measurement methods.
the contrast is generally very high, Some companies claim that the contrast ratio is as high as 8000:1, which is the reason.
if measured according to the American national standard ANSI,
the contrast ratio of plasma TV and LCD TV is mostly around 200:1 or 300:1,This calculation method is to compare the black and white of the same image.

about analog and digital
plasma TV manufacturers attacking LCD TV display images is analog.
plasma TV is all digital.
but in terms of image quality.
analog images make people feel smooth, However, digital images make people jump.

each has its own advantages and disadvantages.
sales volume and sales volume are more than 40 inches.
plasma TV has obvious advantages. Although sharp has produced 45 inch LCD TV and started to go on the market, it is not limited by large-scale mass production of advanced LCD panel, LCD TV can not be compared with plasma TV in terms of large size.
in the market of less than 30 inches.
LCD TV also occupies an absolute advantage compared with plasma TV, but at present, there is no plasma TV less than 40 inches in Chinese market.
LCD screen (LCD)
features: advantages: light and short.
extremely low power consumption; Disadvantages: high cost, slow response, low contrast, (poor performance at low temperature)
plasma display panel (PDP)
features: flat display, high contrast, wide viewing angle, fast response, long service life, Wide working range.

LCD and plasma display
LCD and plasma display have their own advantages.
for the screen no more than
40
inch.
I like LCD very much.
and plasma display works best as a home theater in the room where light can be controlled; LCD screens are more suitable for bright places.
such as kitchens or home offices.
compared with most LCD screens.
plasma screens have better brightness, faster response time (important for watching sports programs and action movies), and higher contrast,Compared with most LCD screens, it can display more pure black.
the cost per inch screen size of plasma is also lower.
this is especially true for TVs no less than
40
inches.

on the other hand.
the power consumption of LCD is much lower than that of plasma, And it doesn't have the annoying problem of plasma TV - pixel shadow (if your child wants to watch "the
wiggles" children's program every day, before he goes to school every day, he will freeze the screen according to the program, As a result, you will see the blurred image of "the
wiggles" when you watch any program.
this is the "pixel shadow."
such a TV will copy other people's recordings without permission.
obviously, it violates the Geneva Convention.
but most importantly,
LCD will not lose brightness as time goes by like plasma.
this is not the case>Once a plasma TV starts to fade.
you can adjust it, but you can't fix it.
LCD manufacturers often say.
their ordinary TV can work
50000 hours - about six years - before the brightness runs out, Plasma TV manufacturers say their latest TVs have only lost half of their brightness in six years.
considering the high quality of today's TVs.
LCD TVs won't fail even after your life is exhausted.
.
LCD TVs will not fail
