In the current technology on the basis of energy-saving LED display energy-saving effect in the end is how to achieve it?
LED display to achieve energy-saving mainly from the power supply to proceed:
In the existing LED display directly on the use of half-bridge or full-bridge high-efficiency switching power supply, coupled with synchronous rectification energy-saving effect is remarkable.
In the drive IC constant current state as much as possible to reduce the power supply voltage, through the red, green and blue of the separate power supply to achieve a better energy-saving effect.
Of course, this non-standard voltage power supply and new technology applications will inevitably rise. From the screen driver IC point of view, energy saving is not obvious, reducing the drive constant current differential pressure will also include new costs, including the problem. Part of the IC business to promote energy-saving design, is nothing more than a sales strategy only.
How to make LED display to achieve further energy saving?
LED display compared to other traditional advertising, its own energy-saving environmental protection "halo." That in addition to starting from the LED display power to save energy, there are those ways to better achieve LED display energy saving.
LED display with brightness self-regulation function. Another aspect is through the LED display brightness adjustment to achieve the purpose of energy conservation.
LED display itself is the use of light-emitting materials is energy-saving products. However, due to the outdoor display area is generally larger, higher brightness, so the power consumption is still large. But the outdoor LED display, due to day and night ambient brightness has changed greatly, LED display brightness in the evening need to be reduced, so the brightness of self-regulation function is very necessary.
