conversion of electrical energy into energy; PN Junction Plus reverse voltage, few carriers difficult to inject, then do not emit light. The two-pole diode, which is produced by the injection-type electroluminescence principle, is known as the LED.Conclusion: Thebiggest difference between LCD and led is the application of two different display technology , LCD is composed of liquid crystal display, and LE
When using a computer, try not to eat anything.
When you are eating things will inevitably not splash, the results of a will be caused by the keyboard and other parts of the pollution, there is likely to splash on the LCD and leave some difficult to clean stains oh. So for the cleaning of the computer and your health, or after eating to play the computer, it is good for yourself and the computer.
