Summary:The invention relates to a method for calibrating an electrophoretic display panel (1) comprising a plurality of pixels (2) capable of representing at least two optical states by receiving driving signals (30), comprising the steps of displaying a first calibration image (22) containing said optical states in a first arrangement on said electrophoretic display panel and providing driving signals (30) to said pixels (2) corresponding to a required image (23) resulting in a second calibration image (24) containing said optical states in a second arrangement on said electrophoretic display panel (1). The second calibration image (24) is compared with said required image (23) to determine differences (26) between said second calibration image (24) and said required image (23) and said driving signals (30) are adjusted in accordance with said differences such that said second calibration image (23) and said required image (24) match. By this method the uniformity of the electrophoretic display (1) is improved.
