This paper presents an AMLED system, consisting of a proposed CMOS pixel driver and a flip-chip bonded blue gallium nitride (GaN) micro-LED (μLED) array with 36×64 pixels of 40×40 μm², for simultaneous display and VLC applications. Measurement results show that the proposed pixel driver can achieve a 20-Mb/s bit rate at 10 cm, which is four times as large as the 5-Mb/s modulation bit rate in previous work.
