What are the differences between LCD and LED?

First, the brightness, the single element of the LED display reaction speed is 1000 times that of the LCD liquid crystal screen, and its brightness is more advantageous than the LCD liquid crystal screen. The LED display screen can also be inaccurate under strong light, and adapts Low temperature of minus 40 degrees.

Second, power consumption, power consumption is one of the most concerned. The power consumption of LED is about 10:1 compared with LCD. In this respect, LED has great advantages.

Third, the viewing angle, the angle of the LCD display is very large, this is a very busy and troublesome problem, as long as the angle of deviation is slightly larger, you can not see the original color, and even can not see anything; and LED It can provide a viewing angle of 160°, which has great advantages.

Fourth, the refresh rate, LED uses electrical energy to convert into light energy, using the injection principle, so its refresh rate is higher, and then better in the processing of video screen.

Fifth, contrast, the currently known high-contrast LCD display is 350:1, but in many cases, it can not meet various needs, but the LED display can achieve higher and wider use.


(The main difference between the two is different display technologies)

Sixth, appearance, LED is based on light-emitting diodes, and its display can be made thinner than LCD.

Seventh, the scope of use, LED display range is wider than LCD display, it can display a variety of text, digital, color images and animation information, can also play TV, video, VCD, DVD and other color video signals, more important It is possible to use a plurality of displays for networked broadcasts.

Eighth, the service life, LED display can generally support about 100,000 hours, under normal circumstances, can be used for decades, and LCD is much less.

Ninth, color, LED screen is more real than the color of the LCD screen, because the color gamut of LED TV is much more than LCD.
