The LED screen is good
LED screen is good.
1. No matter LED TV or LCD TV.

Is it better to buy TV with LED screen or LCD?

the screen itself is LCD. The real LED screen is difficult to be used in the field of home TV, because its pixels are too large and it is difficult to be miniaturized in the case of high resolution.
.
2 In the TV industry.
LCD TV can be divided into LED TV (using LED backlight module to provide light source for screen) and traditional LCD TV (using CCFL cold cathode fluorescent tube as light source).
.
3. In contrast,
LED can easily achieve regional adjustment (it can solve the problem of LCD light leakage to a certain extent, but it can only alleviate the problem, In theory, it is almost impossible to achieve the contrast of the traditional CRT TV set), and the service life is longer (CCFL tube works for a few years, the brightness will drop or it is difficult to start, so it needs to be replaced.
.
4. Although the cost of CCFL is not high.
it is only about 10 yuan, but the maintenance personnel will certainly pay a high price to replace it for you) The working voltage is lower (LED can work at 2V ~ 4V, while CCFL needs nearly 1200V high voltage to start, so special inverter circuit is needed to provide high voltage.
.
LED is better.
LED is the future development trend, and its power consumption is less than LCD.
its service life is longer.
LCD refers to the screen type of LCD TV.
backlight is divided into LED backlight and CCFL backlight, These are just two different forms of backlight.
LED backlight TV sets are thinner and have a longer service life. Most of the new TV sets now use LED backlight.
the hard screen of LCD TV does not mean that the LCD screen of LCD TV is harder.
LED backlight TV sets are thinner and have a longer service lifeThe hard screen LCD TV adopts IPS hard screen technology.
this technology is the most advanced technology in the field of liquid crystal display.
the hard screen of LCD TV has more stable liquid crystal molecular arrangement structure than the soft screen.
IPS hard screen technology optimizes the liquid crystal display The arrangement of molecules.
when the liquid crystal screen encounters external pressure, its molecular structure will sink slightly, but the overall molecular distribution still presents a horizontal state, while when the soft screen encounters external pressure, the liquid crystal molecules of the soft screen present a vertical arrangement, and the molecular sink is more severe, It can be seen that the stability of the molecular structure of the hard screen is much better than that of the soft screen.
