Generally speaking, the color of LED display is softer. The light intensity of the center of the screen is the same as that of the edge of the screen. Basically, it doesn't feel anything. It is suitable for playing games for a long time, It's suitable for watching movies. The light intensity in the center of the screen is slightly different from that at the edge, and the edge is slightly darker. It doesn't matter much. Led refers to light

It is suitable for playing games for a long time, It's suitable for watching movies. The light intensity in the center of the screen is slightly different from that at the edge, and the edge is slightly darker, so it doesn't matter much, The LED refers to the liquid crystal display with light emitting diode as light source.

The difference between LED and LCD

LCD refers to liquid crystal display.
it uses CCFL (cold cathode fluorescent lamp) as light source.
they use different backlight.
compared with the LCD with CCFL (cold cathode fluorescent lamp), the LCD with LED as backlight has the biggest advantage In the following three aspects: first, the thickness of LCD with LED backlight will be further reduced.
the thickness of LED screen notebook panel is about 1 / 2 of that of ordinary CCFL screen.
Second, it has longer service life.
lower power consumption and more environmental protection.
the service life of LED is up to 100000 hours.
even if it is used continuously for 10 hours every day, It can also be used continuously for 27 years.
after using LED backlight system.
it can greatly reduce energy consumption, which is 48% less than the common CCFL LCD.
moreover, LED does not use mercury, which is harmful to the environment.
it is quite environmentally friendly, and CCFL contains mercury.
thirdly, the color performance of LED backlight screen is much better than CCFL.
the color performance of LED backlight screen is much better than that of CCFLThe original CCFL backlight has some problems such as color purity and so on.
its poor performance in color scale leads to LCD's inferior to CRT in gray scale and color transition.
according to the test.
using CCFL backlight can only achieve 78% of NTSC color area, However, LED backlight can easily obtain 100% NTSC color area.
in terms of color expressiveness and color level transition.
LED backlight also has significant advantages.
.
LCD TV gangpu installed two fluorescent lamps as backlight on the back of LCD screen in time.
fluorescent lamps are easy to aging.
the color will turn yellow slowly and need high voltage circuit to light it, Now, with the maturity of LED technology, it has replaced fluorescent lamp as backlight, which has the advantages of bright white color, long service life and low lighting voltage.
in other words,
the LCD is actually an obsolete LCD TV with fluorescent tube as backlight, However, the principle of LCD is the same.
nowadays, most LCD TVs are backlit by LED.
