Remarks:

Double color led display which is also called tri-color led display refers to the display whose pixel is composed of lamps of two different colors. The common combination is r+g or r+b.
1>Double color 1r1g means one pixel of the display is composed of one red lamp and one green lamp. But, in fact, we can see three colors because when red combines with green, another color yellow will appear.
2>Double color 1r1b means one pixel of the display is composed of one red lamp and one blue lamp. Similarly, we can see three colors because when red combines with blue, another color purple will appear.
3>Double color 2r2g means one pixel of the display is composed of two red lamps and two green lamps. Also we can see three colors.
4>Double color 2r2b means one pixel of the display is composed of two red lamps and two blue lamps. Also we can see three colors.
5>Double color 4r2g means one pixel of the display is composed of four red lamps and two green lamps.
6>Double color 4r2b means one pixel of the display is composed of four red lamps and two blue lamps.
