LED display and LCD display is actually its the same, are the LCD is also no difference. The main difference is that makes the screen backlight to produce different light sources .
Ordinary LCD CCFL light source is used , that is, the cold cathode fluorescent tube ( look similar to the copy in the scanning lamp ) , one each side of the screen , on the back of the display has a backlight , the fluorescent material composition, You can make light OLED Display evenly distributed on both sides of the entire back of the screen , so that the whole screen evenly lit. However, because of technical limitations , such as the display brightness is not completely uniform , but it is difficult to find , but also a certain lamp life , a long time will be yellow .
LED LCD screen using a Lcd display modules source , which is the light-emitting diode ( just like on the red blue lights as appliances ) . Such very low power light emitting diodes , lamps and because it is not composed of one array can be uniformly distributed in the back of the LCD screen . Good brightness , the backlight more evenly. Such displays can be thinner and more energy to do , LED life span longer than the life of CCFL , hair color stability is not easy to yellow.
Remember the two display screens are used as there is no difference. But just different light backlight
