Abstract:
1. An active matrix display comprising a select driver (SD) for driving select electrodes (SE), a data driver (DD) for supplying data (D) to data electrodes (DE), a power supply (PS) for supplying a power supply voltage (VB), at least one power supply electrode (PE) for supplying the power supply voltage (VB) to pixel driving circuits (PD) of at least one line of pixels ( the pixels ( means (LL) for determining a load (AL; MA; IL) on the at least one power supply electrode (PE), wherein the load (AL; MA; IL) is an image load indicating a ratio of the summed grey level of the pixels ( means (CO) for controlling a level of the power supply voltage (VB) depending on the load (AL; MA; IL) determined.
