What are the advantages of LED backlight and traditional CCFL backlight?
Today, Mai Jing electronics Xiaobian will give you an answer. Let's take a look: LED backlight refers to the use of LED (Light emitting diode)As a backlight for a liquid crystal display. And the traditional CCFL (Cold cathode tube)
Compared with backlight sources, LED has the characteristics of low power consumption, low calorific value, high brightness and long service life, and is expected to completely replace the traditional backlight system in recent years.
In the electronics industry, backlight is a form of illumination and is often used on LCD displays.
The difference between the backlight type and the front light type is that the backlight is illuminated from the side or behind, while the front light is illuminated from the front as the name implies.
1. led backlight has long service life.
In general, compared with other general lamps, led bulbs have a very long service life and can be used for more than 10 years.
2. led backlight can adapt to various environments. General energy-saving lamps are very easy to break if they are frequently turned on and off, the led bulb can adapt to this high working environment.
3. The production of led backlight adopts the world's top light distribution technology. Its light source is a surface light source, which can increase the light emitting surface and is very friendly to people's eyes.
4. There are no harmful substances such as mercury and lead in the led backlight, which does not pollute the environment.
5. The temperature of LED backlight is generally specified in the scope of use-20 C ~ 80 °C.
