There are 2 ways of using the led , 1.using of led sigle valve, including the lights backsources Led , infrared Leds and the other one is "Led display ",Now in the chinese company ,there are some difference of the led producing procedure between the international company when they produce the led materials .Led display is made by the led .It use the lower voltage driver to scann ,it has some adavantage such as "lower power , low cost, high brigtness ,less fault ,big viewing angle,big distance of view etc .
Compare with the Led display and Lcd montior ,there are some advantage here ,for example ,the brightness ,power cost and refresh rates are all more better then the lcd monitor. Normally LED and LCD power consumption ratio is about 10:1， and higher refresh rate makes the LED have better performance in the video .it can provide the perspective of 160 ° wide and can play the text and characters ,numbers ,color pictures and video informations ;also can broadcaste the signal of TV ,Video ,VCD ,DVD etc .
Pieces of display can also broadcast networking The response speed of a Organic LED display is about 1000 times more than the Lcd monitor .It also can be watched under the stronger brigtness .Use the Led technology ,you even can make a more brightness and ,thinner led display under the temperature -40 degree .
Lcd is a crystal screen ,it is including the TFT ,UFB,TFD ,STN and other types of liquid crystal Screen .
The laptops Lcd monitoer normally use the TFT .TFT the full name is " Thin Film Transistor "which is an active matrix type liquid crystal display, ,it can set special fluorescent tubes on the back .It can take the initiative on the screen to control each pixel independently.This is also called "active matrix TFT . this can be greatly improved the reaction time.It's about 80 milliseconds and the reaction time of STN is about 200 milliseconds! Compared with STN, TFT has excellent color saturation, reducing power and higher contrast, under the sun still can watch very clearly, but the drawback is more power and higher cost.
Simply said ,the LCD and LED are 2 different display technology .Lcd is made by the composed of liquid crystal displays But led display is made by the led .Compared to the Lcd , LED display have more advantageson the brightness ,view angle ,and refresh rates .
