Advantages of Energy saving LED Display
✅Save operating costs (electricity bills):Special power supply settings enable precise control of the voltage, thereby reducing power consumption and electricity bills.
✅ Save installation cost:Lower energy consumption means a lower temperature of the screen, which allows us to omit additional cooling devices such as air conditioners.
✅Lower MaintenanceRate:As working temperature reduced, the lifespan of LED lamp could be extended, it would be in lower rate for repairing.
✅Excellent VisualEffect:While the low temperature rises, high brightness and refresh are maintained. Also IC has added open circuit detection to eliminate ghosting and tailing.
The biggest disadvantage of Energy-Saving LED Display Screen is that the purchase cost is higher than normal screens, but you will thank yourself for this decision after six month or one year.
Common LED Display VS Energy-saving LED Display
1.Different Design of Power Voltage
For the common LED Display, the power supply adopts a single-voltage unified power supply. But the energy-saving power supply is based on a dual-voltage power supply design. It means the R, G, B lamp will work under its normal working voltage.
You might have doubt on reducing the voltage supply to achieve energy saving, Is that voltage sufficient enough to load the screen?
In fact, the best working voltage of LED Lamp is about 1.8V-2.2V(Red lamp) and 2.8V-3.4V(Blue and Green lamp). However, the supply voltage provided by the traditional LED Display is much higher than its required working voltage. So it can reduce unnecessary losses after adopting the new-designed power supply.
2.Different Design of PCB Board
The Energy-saving LED Display also has its own unique PCB board design, with the energy-saving power supply
to achieve accurate voltage distribution. Change a words, the lamps can be swimming at the ideal work environment, the PCB equal the swimming pool and the power supply equal the water. This design can also be called “Common Cathode”.
On the contrary, normal LED Display, we call it “Common Anode”. As it uses a unified power supply design, no matter it need more or less voltage.
That’s why the energy-saving screen also called by Common Cathode Energy-saving LED Display.
3.Different Design of Driving IC
Another indispensable element is the Driver IC. The innovation of Drive IC is mainly reflected in itslow switching voltageandcommon cathodedesign, the former can save energy by 5%-8%, the latter can save energy by 20-25%.
4.Brightness Design
How to achieve a Energy-Saving LED Screen
A.High-Brightness LED Lamp
High Brightness LED Lamp is the Key point for an Energy Saving LED Screen, which means it has low PF value at the same brightness. You can get the same LED Screen Brightness, but with low voltage, which will reduce the power consumption.
