LCD TV, also known as LCD TV, is to change the crystal structure of the thin film transistor on the LCD panel through the current to make it display. LCD TV has many characteristics, such as rich colors, up to 16.7 million colors. At present, the resolution of 32 inch LCD TV can reach more than 1366 * 768, and most of them support 1920 * 1080 resolution; LCD TV has a longer service life. Generally, the service life of LCD TV is about 50000 hours. In addition, LCD TV also has high brightness, high contrast and other significant features.

What are the advantages of LCD TV?

LCD TV has many characteristics, such as rich colors, up to 16.7 million colors. At present, the resolution of 32 inch LCD TV can reach 1366 * 768, and most of them support 1920 * 1080 resolution; LCD TV has a longer service life, generally about 50000 hours.
in addition,
LCD TV also has high brightness, high contrast and other significant characteristics.
.
advantages and disadvantages of LCD TV:
advantages: 1. In appearance,
LCD TV body is thinner, especially the latest LED backlight TV, The thickness is less than 1 cm; 2. The power consumption of LCD TV is relatively small, which is more energy-saving than plasma TV of the same size; 3. The brightness of LCD TV is relatively high, and the picture quality will not change much in a relatively bright environment, and it is still relatively gorgeous.
for the static picture,
LCD TV is also more clear and delicate.
.
disadvantages: 1. The dynamic definition of LCD TV is not high.
this is mainly due to the limited deflection speed of liquid crystal molecules, So LCD TV will appear the phenomenon of tailing; 2. There is more or less light leakage in LCD TV, especially in the black environment.
because of the problem of light leakage.
LCD TV is not deep enough to show black, and the contrast is not high enough compared with plasma TV, so the picture level is not strong enough.
.
advantages summary: 1. Beautiful appearance; 2; 2. Low power consumption, more power saving; 3. High brightness.
4In 2010 sharp exhibited 152 inch at the world electronics show.
.
disadvantages: 1. Low dynamic definition; 2( At present, less than 2ms has been achieved.
this problem has been basically solved.) 2. There is light leakage, which leads to the lack of black expressiveness and low contrast.
(the current technology has basically solved the secondary problem.
the LED type basically does not have this problem).
now there are two kinds of LCD and led in LCD TV.
the difference is that the backlight light source, LCD is cold cathode fluorescent tube, LED is light-emitting diode.
compared with LCD TV, LED is lighter, more energy-saving, more colorful and realistic It is more energy-saving.
of course, the price is also higher.
at present, there are few manufacturers making LED LCD panels.
Samsung is the main mass production company.

in addition, plasma TV is also introduced here.
people are easily confused with LCD TV.
.
.
plasma TV, also known as PDP TV, relies on high voltage to activate the special gas in the imaging unit, It can generate ultraviolet light to stimulate phosphorescent material to emit light.
plasma TV completely eliminates the phenomenon of picture shaking.
and it has high definition, which will not cause visual fatigue and eye damage.
at the same time.
theoretically, Plasma can achieve unimaginable large picture.
using this technology.
you can enjoy the theater effect even at home.
.
advantages and disadvantages of plasma TV.
advantages: 1. Plasma TV is better than LCD TV in the sense of image hierarchy.
especially in the performance of black scenes, LCD TV can't be compared with plasma TV at all; 2. Because of the working principle,Compared with LCD TV, plasma TV has higher dynamic definition, which makes the performance of sports games, action movies and other high-speed sports more fluent, and will not appear the phenomenon of tailing; 3. Plasma TV is the only TV that can be fully digitized at present. Without D / a conversion, it can avoid the image quality reduction caused by image signal distortion.
while LCD TV must control brightness and gray scale through analog voltage.
therefore, image signal still has certain loss in the transmission process.
.
disadvantages: 1 Plasma TV can't be as slim as LED backlight LCD TV.
for users who care about TV appearance, plasma TV is not pleasing; 2. Because of the luminous efficiency, the brightness of plasma TV is not as high as that of LCD TV with independent backlight, so the viewing effect of plasma TV will be greatly reduced in bright places.
it is also due to the luminous efficiency.
in order to improve the brightness, the power consumption of plasma TV is naturally larger than that of LCD TV; 3. Plasma TV still has the imagination of screen burning.
the so-called screen burning is that plasma TV keeps a certain picture for a long time (with the development of plasma technology,
this time is also longer and longer), which will make a certain picture stay on TV for a long time.
however.
generally, this phenomenon will disappear after a period of time.
.
advantages summary: 1 Outstanding color; 2. High dynamic definition; 3. There is no signal loss in the whole digital process.
.
4. Theoretically, it can achieve a large size.
.
disadvantages summary: 1; 2. Low brightness and high power consumption; 3. There will be screen burning.

.
     There are few manufacturers of this kind of TV panel.
the technology is closed strictly.

the technology is mature.
