Abstract

A microcontroller-based driver was designed and developed for dot-matrix displays made with organic light emitting diodes (OLEDs). It was made by modifying driver designed for dot matrix LEDs made with inorganic semiconductors. The driver was designed with adjustable driving frequency, pulse-width, polarity and pulse-amplitude. It is a generalized driver suitable for operating OLED dot matrices made with different electroluminescent organic materials or in different device structures. A driver system was fabricated to drive an OLED panel in 40×7 format
