This article proposed micro light emitting diode (microLED) virtual pixel array design and driver. The proposed virtual pixel array effectively increases the pixels per inch and reduces parasitic capacitance for alleviating ghosting effects. The push-pull supply buffer in the proposed driver is compensated by the dynamic Miller compensation technique to achieve fast transient response and reduce the ghosting by 50%–73%. Four times screen resolution can be obtained compared to conventional designs. A 95% high-efficiency microLED driver has the lowest 45 μW power consumption. The proposed supply buffer can drive microLEDs in 51-inch display panel, which is composed of 214 small 96 × 64 microLED panels for automotive display.

RGB虚拟像素MicroLED显示器中的动态补偿和95％高效电源缓冲器，可将重影降低73％，并实现四倍的屏幕分辨率

本文提出了微发光二极管（microLED）虚拟像素阵列的设计和驱动器。所提出的虚拟像素阵列有效地增加了每英寸的像素并减小了寄生电容以减轻重影效应。建议的驱动器中的推挽电源缓冲器通过动态Miller补偿技术进行补偿，以实现快速的瞬态响应并减少50％至73％的重影。与传统设计相比，可获得四倍的屏幕分辨率。95％的高效microLED驱动器具有最低的45μW功耗。提议的电源缓冲器可以驱动51英寸显示面板中的microLED，该显示屏由214个用于汽车显示的96×64小型microLED面板组成。
