As the backlight system of the latest generation of LCD panels, LED backlight beads have many advantages compared to traditional CCFL backlights, but also have some disadvantages. Below, Shenzhen Development Optoelectronics will list the advantages and disadvantages of LED backlight beads as follows. Knowing these will help you to choose LED backlight displays more rationally.
advantage:
First, it is more energy-efficient. Compared with the ccFL backlight, the LED backlight bead is much more energy-saving. Generally, civil products of the same specification can save more than 40% of energy. According to our evaluation data, some high-quality LED backlight displays can save up to 60% more energy than mainstream CCFL products, which is definitely very energy-efficient. And, with the further maturity of LED backlight technology, LED backlight displays may be more energy-efficient in the future.
(Energy-saving is certain, but it is not as much as 60% or 40% you think when used. For example, a mainstream CCFL tn display has a maximum power consumption of 40W, an LED backlight has a maximum power consumption of 20W, and usually only a difference of 10W at 50 brightness. about.)
Second, green and environmental protection. The mercury in the CCFL backlight is a substance that is quite harmful to the environment, but the LED backlight does not contain this harmful substance. We must know that the total global output of displays in 2009 reached 220 million units. If LED backlight displays become popular in the future, it will be very helpful to the improvement of the global environment.
Third, the color gamut is wider. Since the LED backlight module emits more pure white light than the traditional CCFL, it is easier to increase the color gamut of the display using the LED backlight. The improvement of the color gamut can make the monitor display more colors and make the color performance better.
(The color gamut is one aspect, and the nature of the panel is the other. The final color is "filtered" on the panel. The wide color gamut TN screen is oversaturated, which is more pleasing to the human eye, but the reality is not enough. It's kingly way.)
