This paper proposed MicroLED virtual pixel array design and driver. The proposed virtual pixel array effectively increases the pixels per inch (PPI) while having a relatively low ghosting. The push-pull supply buffer in the proposed driver is compensated by the dynamic Miller compensation (DMC) technique to reduce the ghosting by 50%-73%. Four times screen resolution can be obtained compared to conventional designs. 95% high efficiency microLED driver has the lowest 45μW power consumption.
