Three different driving methods for Micro-LED

Micro-LED is a current-driven light-emitting device, and its driving mode generally has only two modes: passive addressing drive (PM: Passive Matrix, also known as passive addressing, passive addressing, passive drive, etc.) and active Addressing drive (AM: Active Matrix, also known as active addressing, active addressing, active drive, etc.), this article will also analyze a "semi-active" addressing drive method. These modes have different driving principles and application characteristics, and the following will introduce their principles in detail through the circuit diagram. What is PM drive mode? Passive addressing drive mode connects the anode (P-electrode) of each column of LED pixels in the array to the column scan line (Data Current Source), and at the same time connects the...
