OLED display module was used as a man-machine interface in the traffic signal system. In this design

the OLED display realizes the 12864 pixels of picture and character monochrome display with 16 gray-scales. The intelligent traffic signal system with OLED display not only can provide good man-machine interface

and adapt to the harsh outdoor environment

but also can achieve multi-phase and multi-time control of traffic flow. The intelligent traffic signal system with OLED display uses the ARM9 as processor

so a scientific algorithm can be embedded in it to carry out effective control of traffic flow.
