Design of an Integrated OLED Driver for a Modular Large-Area Lighting System

摘要

The concept of a flexible, large-area, OLED-based lighting system with a modular structure and built-in intelligent light management is introduced. The paper describes the design of a high-voltage integrated circuit for driving and controlling an individual OLED tile in this modular lighting system. The chip comprises a switching DC-DC buck converter for generating the OLED current and a sensitive analog feedback loop for adjusting the duty cycle of the converter's PWM control signal. The chip was designed in the 80V 0.35μm I3T80 technology of ON Semiconductor.
