I think LCD TV is mainly for practical use. Most people buy LCD TV with high quality. Of course, the brand should not be too bad, otherwise, the quality and service are hard to guarantee. Now the production technology of LCD TV is very mature. The quality of domestic brands is no worse than that of imported ones, but the price is more acceptable to Chinese people. The two LCD TVs I use at home are TCL's, the largest brand in China. After more than two years, there is no problem at all. But everyone's preferences are different, in short, choose a good quality and like it.

Is there any difference between flat panel TV and LCD TV??

the quality of domestic brands is no worse than that of imported ones, However, the price is more acceptable to Chinese people.
the two LCD TVs I use at home are all TCL's.
there is no problem after more than two years.
but everyone's preferences are different.
in a word, choose one with good quality and I like.
.
plasma TV (PDP) and LCD TV (LCD) are flat panel TVs.
they are like twins, Although they are very similar on the surface, However, there are great differences in essence.
the biggest difference between the two is that they use different panels.
that is to say, their imaging principles are very different.
plasma TV relies on high voltage to activate the special gas in the imaging unit.
to make it produce ultraviolet light to stimulate the phosphorescent material to emit light.
while LCD TV changes the thin-film crystal on the liquid crystal panel by current In addition, plasma TV and LCD TV have their own characteristics. For example, plasma TV is cheaper than LCD TV in the same size, However, LCD TV has advantages in power-saving performance and display resolution.
.
about clarity.
.
enterprises producing LCD TV often claim to be superior to plasma TV in clarity.
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 HD signal processing, It is not enough to judge only from the physical resolution of the screen.
therefore.
it is not scientific for LCD TV manufacturers to attack plasma TV only from the physical resolution of the screen.
.
.
about 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". "
for TV sets used in living rooms and bedrooms,
few people watch TV at an angle of more than 120 degrees, so from this angle, There is no need for both sides to attack the perspective.
.
.
about the response speed.
.
the response speed used to be the weakness of LCD TV.
although it has been greatly improved in technology recently, it is sometimes targeted by the enterprises producing plasma TV.
some enterprises claim that their LCD TV response time has been reduced to 8 ms, but in fact, the, Most of the LCD TVs on the market have a response time of about 12 Ms.
even the LCD TVs that have claimed that the response time has dropped to 8 ms.
there is still a tailing phenomenon when playing fast moving images, because the 8 ms response time claimed by enterprises is measured when playing still images.
.
.
for a fast moving black image or white image.
the response time of LCD TVs on the market is about 12 MsLCD TVs all have slight tailing, but that doesn't mean that plasma TVs are perfect in this respect. For fast-moving white objects, plasma TVs also have slight tailing, except that when fast-moving objects are changed to black, Plasma TV is superior to liquid crystal TV in processing moving images.
but when the still image appears at the same position of plasma screen for a long time, it may be burned.
when plasma TV is burned.
when switching on or off, plasma TV will be burned, The image that has been playing for a long time will appear indistinctly on the screen, as if it is printed on the screen, and this has become the target of some LCD TV manufacturers attacking 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 enterprises claim that the contrast is as high as 8000:1, which is the reason.
if the contrast is calculated according to the American national standard ANSI.
the contrast between plasma TV and LCD TV is mostly about 200:1 or 300:1, which is to compare the black and white colors displayed in the same image.
.
.
about analog and digital.
the comparison between plasma TV and LCD TV is very important
the image displayed by LCD TV is analog, while plasma TV is all digital.
but in terms of image quality, the analog image is smooth, However, digital images make people feel leaping.
.
.
each has its own advantages.
.
sales volume and sales volume.
.
in the market of 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 production of advanced LCD panel, LCD TV can not be compared with plasma TV in large size.
in the market of less than 30 inches.
LCD TV also occupies an absolute advantage compared with plasma TV. However, there is no plasma TV of less than 40 inches in Chinese market at present.
.
in this paper, the development trend of LCD TV is analyzed
