From the appearance, the plasma TV body is light and thin, the screen is wide, and the picture is clear "Thin" is a major feature of plasma TV.

The difference between LCD TV and plasma TV

"thin" is a major feature of plasma TV.
a 60-70 inch TV is only 67 cm thick; In addition,
it has a wide perspective (up to 180 degrees); Secondly, technically speaking, plasma TV adopts digital display mode, which is conducive to improving the clarity of imaging.
at present, plasma TV can convert analog signal into digital signal; Moreover, its driving voltage is more superior than that of previous TVs.
it can be used to watch TV, VCD and DVD, as well as digital TV and satellite TV on the Internet, making it the first choice for home cinemas.
in addition,
plasma TV has rich and easy-to-use interfaces, which can be connected to personal computers, mobile phones, etc But at present, the technology of plasma TV is not perfect.
there are still some defects in some aspects.
for example, the power consumption is large.
it is usually more than 300W, which is a big power consumer in household appliances; It has no competitive advantage in the resolution, contrast and resolution of panel image quality; The problem of heat dissipation is still difficult to solve.
but at the current technical level.
compared with plasma TV, LCD TV has certain advantages.
.
with its ultra-thin, clear, environmental protection and energy saving features, LCD TV has become another main product in the high-end color TV market.
.
LCD TV has no flicker and radiation.
it can reduce people's visual fatigue; It has rich interfaces and can connect audio and video devices such as computers and DVDs, which can meet the needs of digital TV broadcasting in the future.
.
LCD TV has more colors than plasma TV.
the power consumption is only one third of that of plasma TV; Generally, the life of LCD TV is about 60000 hours, twice that of plasma; The high brightness and high contrast of the new generation LCD TV are also better than that of plasma.
the new generation LCD TV has the advantages of high brightness and high contrastAn excellent LCD TV must perform very well in brightness, contrast, resolution and visual angle.
.
like plasma TV, LCD TV has no flicker, thin thickness and light weight.
but it is inferior to plasma in large screen.
in large screen high-end TV market.
plasma has inherent advantages in technology and price, Therefore, there was a saying that "plasma is bigger and liquid crystal is smaller."
30 inch has always been considered as the dividing line between liquid crystal and plasma TV.
.
because liquid crystal (LCD) is an organic compound with regular molecular arrangement between solid and liquid.
under the action of different current and electric field,
liquid crystal molecules will rotate 90 degrees regularly, In recent years, however, with the development of science and technology, it is difficult for LCD TVs to be large in technology, LCD TV also began to develop towards large screen.
soon after the launch of the world's largest 46 inch LCD TV.
recently, the 50 inch LCD TV on display in the United States set a new record.
.
in terms of price.
which one is better with the same specifications and models, the price of large screen LCD is generally higher than that of plasma, while the price of small screen is lower.
in the popular 30-34 inch TVs,
the price of LCD is falling faster than that of plasma.
.
in the west,
LCD TV has penetrated into the kitchens, living rooms and bathrooms of many families,The advantages of LCD TV, such as ultra-thin, wall mounted, flat and power saving, are fully displayed.
.
according to the introduction of the customer service department of Suning Electric Appliance Shenzhen store.
LCD TV is usually small in screen, so it is suitable for close-up viewing and home use with small room range; Plasma, because of its large screen, is usually placed in a large space, which is suitable for long-distance viewing.
at present, LCD TV and plasma TV are the products concerned by the majority of consumers.
there are many friends who are not clear about the concept and principle of these two products. Let's explain them below.
.
.
LCD TV.
also known as LCD TV, It uses the same display technology as laptop and desktop flat panel displays.
its vivid images are generated by a special glass panel and transistors on it.
however, this kind of TV is expensive.
especially for large-scale LCD TVs over 40 inches.
some LCD TVs are not very clear when viewed from the side.
the images are not very clear>At present, LCD TVs in the domestic market are mainly 15-32 inches.
there are also 42 inch LCD TVs.
.
.
plasma TVs.
also known as PDP TVs, It uses the gas between two glass substrates to show colorful and vivid pictures.
this kind of TV is a little cheaper than LCD TV.
especially for large TV above 40 inches.
like LCD TV.
plasma TV is also very thin.
until recently.
many plasma TVs still have many shortcomings to overcome, including relatively short service life, low cost and low cost It is possible to leave some fixed images on the screen for a long time, and to be unable to work in high latitudes, etc.
in this paper, the author analyzes the reasons for the problemHowever, these problems have been partially solved at least in some better models.
.
.
in addition.
digital light display rear projection TV is usually cheaper than LCD TV and plasma TV, and its thickness is often much thicker than them.
it is actually a kind of rear projection TV.
the old rear projection TV has a large volume ratio, and this new generation of rear projection TV adopts digital technology, It's also more lightweight.
the digital light display rear projection TV uses a special chip at the back to form images.
the chip produced by Texas Instruments contains thousands of small mirrors, The light source is reflected on the display screen through these small mirrors to form an image.
the screen of digital light display rear projection TV is simpler than that of LCD TV and plasma TV.
it is also cheaper.
its picture is very clear and moving.
and the price is also lower, But one disadvantage is that it is not as thin as LCD TV and plasma TV.
.
.
you should pay attention to some confusing terms.
the so-called "LCD" TVs sold by some manufacturers such as Sony Corporation.
their screens are not real LCD screens, they are actually rear projection TVs, It's just that the rear of the TV is a mini LCD, not a digital light display rear projection chip.
some TVs are called "flat" TVs.
in fact, they are just ordinary TVs, However, the common curved glass of TV screen is replaced by flat glass.
.
.
finally.
pay attention not to confuse flat TV or large screen TV with high-definition TV.
many flat TV and large screen TV currently sold in the market can't play high-definition TV programs.
at present, many flat TV and large screen TV can't play high-definition TV programsYou can buy an ordinary TV equipped with HDTV program receiving device to watch such programs.
if you want to buy a large screen flat-panel TV.
and want to watch HDTV at the same time, you need to carefully check whether the TV you want to buy has HDTV program function.
then.
you also need to open cable TV or satellite TV service to provide HDTV programs, Watch these programs through a special set-top box, or use the roof antenna to receive high-definition TV signals.

I think.
If I choose LCD, I will at least protect our eyes, especially if there are children at home.
but the price will be relatively expensive.
it's better to go there in one step.
