Abstract

This invention relates to a method and apparatus for improving display equalization of an organic light-emitting display (OLED) panel. It comprises a detector. The detector detects differences among actual driving currents or brightness of plural pixels for the panel, or difference between driving currents or brightness of the pixels and a standard driving data value. Therefore, it generates multiple calibration data values for the equalized actual driving currents. Subsequently, while driving the panel, the brightness of those pixels for adding those calibration data values to the driving data values of the panel.
