Abstract
An electroluminescent (EL) panel with 2T1C subpixels is compensated for initial nonuniformity ('mura'). The current of each subpixel is measured at a selected time to provide a status signal representing the characteristics of the subpixel. A compensator receives a linear code value and changes it according to the status signals. A linear source driver drives the panel with the changed code values.
