In this paper,a new passive driven full-color display device with a special sub-pixel arrangement is proposed,which integrates blue micro light-emitting diode(Micro LED)and red and green organic light-emitting diode(OLED).The device can achieve full-color display without massive transfer and has higher efficiency and longer life than traditional full-color OLED and Micro LED devices.In addition,the blue and green sub-pixels are reversed in parallel,which can reduce the electrode routing and improve the pixel density of the device.According to the special structure of the device,a new driving scheme is designed in this paper,which takes field programmable gate array(FPGA)as the main controller and uses the driver chip to provide stable current to light the LED,to realize the full-color display of the device.The feasibility of the device is further verified by simulation test.
