Some people often ask the difference between the LCD and the LED display on the Internet. Is the LED backlight energy-saving and environmental protection advertised by the manufacturer a gimmick? First of all, let us know the merits and demerits of the LED backlight, and we can make the correct judgement.

 

The advantages of LED backlight are:

 

1. Screen can be made thinner, we pay attention to some LCD display, you can see a few filaments of CCFL lamp, in order to make the screen even luminous, but also need to add some other devices, so it can not be very thin; and the backlight is different, LED backlight itself is flat luminous material, without adding other. The device.

 

2. No yellowing and darkening. Like fluorescent lamps and fluorescent lamps, CCFL fluorescent lamps will age over a long period of time, so the traditional notebook screen will be yellowing and darkening after two or three years, while the LED backlight screen will have a much longer life, at least two or three times as long.

 

3, more energy saving, LED is a semiconductor, working under low pressure, simple structure and low power consumption.

 

4. More environmentally friendly, mercury in CCFL lamp has a great pollution to the environment, harmless recycling is very difficult.

 

Disadvantages of LED backlight source:

 

1. The relative price is higher, and the difference between the traditional CCFL backlight display and the traditional CCFL backlight display is between 100-300 yuan.

 

2, the promotion of new technology.

 

From a long-term trend, LED backlight technology as a replacement technology product is bound to slowly spread and gradually occupy the mainstream of the market.
