Method and apparatus for achieving active matrix OLED display devices with uniform luminance

摘要

A method and apparatus for achieving an active matrix OLED display device which consists of a plurality of pixel devices with uniform luminance are described. Each of the pixel devices includes a driver unit to drive the OLED to illuminate and a compensation unit to adjust Vsg of the driver unit to compensate for the characteristic variations of the driver unit, thereby the luminance of the display device is less affected by the characteristic variations of the driver unit.
