Based on super pixel technology,a digital driven strategy for color silicon OLED (Organic Light Emitting Diode) micro-display is proposed. By reusing adjacent pixel information,a single pixel can be used for imaging multiple adjacent pixels to greatly improve the display resolution. A digital driving circuit for color OLEDoS (Organic Light Emit-ting Diode on Silicon) micro-display is designed. Under the condition of 120 Hz frame rate,256 grey levels and 4K display resolution can be achieved while the circuit area and data transmission per second are only 50％ of the traditional driving mode. The test results show that the average current range of OLED pixel realized by the driving circuit is 13.1 pA～3.74 nA,which can meet the demand of near-eye display of micro display.
