P‐41: A Combined PAM / PWM Driving Scheme for High Uniformity of Micro‐LED Displays

This paper handles further development of a proposed combined PAM and PWM driving scheme for Micro‐LED displays. A prototype display which consists of 64x3x64 pixels is driven by a combined PAM and PWM scheme. The occurring non‐ uniformity of Micro‐LED displays is improved by two extensions in the driving scheme. First, an analog bit for high luminance compensation and second, a compensation method that uses the high gray scale of digital driving schemes.
