P31.25 outdoor double color energy saving LED display screen


Tri-color/double color led display,we also call it as double color led display and fake full color led display. Why we called it as fake full color led display? Because each pixel is composed up of two led lamps, such as one red and one green led lamp. And when the two lamps working at the same, it appearances the yellow color, so this display can display the red, green and yellow three colors.
The tri-color led display is widely used to display the color-full texts, data, graphics and animations etc. And it can be connected to various data equipment, show the dynamic data and advertising in the real-time. With the dazzing colors, the visual of the display is obvious. So the tri-color is the more widely used led displays.

4.For the some middle East countries, such as the Israel, Jordan, Iraq and a few of European countries people will like the red and blue tri-color led display.
