LED displays in the industry are the 5V power supply, and do not know whether to use 3V …

Now the market by research and development and sales of LED display (outdoor advertising screen, full resolution 000) are the family of 5V power, why do not the 3V it?

you can go to for advice about
hope you can help with 3V Oh, but you have to change the lamp power, and the board of the demand for power! 3V can also be used, but you have to change the lamp power, and the board of the demand for power!
right.because the normal voltage of 220V.to our customers so to explain.electric lighting.LED display each pixel RGB are generally the red-green-blue or a red 2, green and blue each one,

green and blue voltage drop (voltage) in the 3V or more generally, if you used 3V voltage of the LED will not be able to issue a normal brightness, than to use the 3V power supply, so we are 5V

LED how much power the V of each pixel with the number of LED related, it is not possible to jump if the RGB Series 3, we have to use the power of 12V, 6, we have to use 24V power
