First of all, we have to know what are LED lamp beads? The English name of LED is (light emittingdiode), and the LED lamp bead is the English abbreviation of light-emitting diode, abbreviated as LED, which is a popular name. The full name of LED is semiconductor light-emitting diode, which is a light-emitting device made of semiconductor materials to directly convert electrical energy into light energy.

Compared with CCFL backlight, LED backlight lamp beads greatly save energy. Generally, civilian-grade products of the same specification can save energy by more than 40%. According to our evaluation data, some high-quality LED-backlit displays can save more than 60% energy compared with mainstream CCFL products, which is definitely very energy-saving. Moreover, with the further maturity of LED backlight technology, LED-backlit displays may be more energy-efficient in the future.

LED lamp beads are widely used in lighting, LED large screen display, traffic lights, decoration, computers, electronic toys gifts, switches, telephones, advertising, urban glory projects and many other production fields. The most common LED lamp beads are plug-ins and SMD patches. The low-power specifications of plug-in LEDs include: straw hat/helmet, round head, concave, oval, square (2*3*4/2*5*7) bullet head, flat head, (3/5/8/Bread type) Piranha, etc. SMD patches are generally divided into 3535/3528/5050 and other front-side light sources, and 1016/020 and other side-emitting light sources.

Mercury in CCFL backlights is a substance that is quite harmful to the environment, but LED backlights do not contain such harmful substances. It should be known that the total global output of displays in 2009 reached 220 million units. If LED-backlit displays are popularized in the future, it will be very helpful to improve the global environment.

Since the white light emitted by the LED backlight module is purer than that of the traditional CCFL, the display using the LED backlight is easier to improve the color gamut. The improvement of the color gamut can make the monitor display more colors and make the color performance better. Theoretically speaking, LED backlight has longer life and longer brightness decay period than CCFL backlight. Benefiting from the cost advantage and the rapidly expanding LED application product market, the domestic packaging industry has continued to grow rapidly. At present, it has formed a certain industrial scale and has become an important LED packaging production base in the world, and has initially formed the Pearl River Delta region and the Yangtze River Delta region. , Fujian and Jiangxi regions and the four major LED industry-intensive areas in the Bohai Rim region.
