Plasma television (PDP) and liquid crystal television (LCD) are flat panel TVs. They are like twins. Although they are very similar on the surface, they are very different 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 produce ultraviolet light to stimulate phosphorescent material to emit light.

Plasma display panel (PDP) and liquid crystal display panel (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 difference between ion TV and LCD TV

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.
it produces ultraviolet light to stimulate phosphorescent materials to emit light.
while LCD TV changes the thin-film crystal on the LCD 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 it is not only the physical resolution of the screen that determines the definition of flat panel TV.
the circuit also directly affects the definition of HD signal processing, and it is not enough to judge from the physical resolution of the screen.
therefore.
it is not scientific for LCD TV manufacturers to attack plasma TV from the physical resolution of the screen.
.
in this paper, the definition of flat panel TV is analyzed
about the angle of view.
.
no matter how to defend LCD TV.
plasma TV is better than LCD TV in the angle of view, of course, plasma TV is not "no angle problem". "
for the TV used in living room and bedroom.
few people will 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 the enterprise is measured when still images are played.
.
.
for a fast-moving black image or white image,
LCD TV has slight tailing, but this does not mean that plasma TV is perfect in this respect. For fast-moving white objects, plasma TV also has slight tailing, But when the fast-moving object is changed to black, there will be no more tailing.
.
.
about burning.
.
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, it may appear burning.
when plasma TV appears burning.
plasma TV is better than LCD TV in processing moving imagesWhen the machine is switched on or off, the image that has been playing for a long time will appear vaguely on the screen, as if it is printed on the screen, 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.
.
the image of plasma TV manufacturers attacking LCD TV is analog.
and plasma TV is all digital.
but from the perspective of picture quality.
the analog image makes people feel 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't compare with plasma TV in large size.
in the market of less than 30 inches.
LCD TV also has an absolute advantage compared with plasma TV. However, there is no plasma TV of less than 40 inches in the Chinese market.
plasma TV (PDP) and liquid crystal TV (LCD) belong to flat panel TV.
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, the imaging principle is very different.
plasma TV relies on high voltage to activate the special gas in the imaging unit.
to make it produce ultraviolet light to excite phosphorescent material to emit light.
while liquid crystal TV changes the inner crystal of thin film transistor on the liquid crystal panel through current In addition, plasma TV and liquid crystal TV have their own characteristics.
