“…The capacitors C1 works as the storage capacitor, which is used to store the data signal. Generally speaking, the working period of the pixel driver circuit can be divided into two parts, display driving time and display holding time[8]: Display driving time. When the driving signal Vscan is at the low-level voltage, T1 works in the saturation region, and the data signal can be transmitted to T2 and C1.…”

Because Micro‐LED is the current‐driven device, there are usually two types of the matrix driving circuit, passive matrix driving circuit, and active matrix driving circuit. Comparing these two driving circuits, the active driving circuit can achieve better brightness uniformity, higher contrast and lower contrast. Therefore, most of Micro‐LEDs use active matrix driving circuit. In this paper, a study of active matrix circuit design for Micro‐LED displays and beyond display applications such as visible light communication will be reported. The pixel circuit integrates two parts of VLC together, the emitter and the receiver. When the LED is on, it can work as the emitter of VLC. When the LED is off, the photodetector can work as the receiver of the VLC. This can offer more varieties of the application, such as face‐to‐face data transmission, under‐screen fingerprint identification and so on.
