ACTIVE MATRIX DISPLAY DEVICE

摘要

The invention relates to an active matrix display device (6) comprising a display panel (2) with a matrix of display pixels (3), and row and column electrodes (11,12) coupled to the display pixels (3). Each of the display pixels (3) has a current mirror circuit adapted to receive a programming current (Iprog) via the column electrodes (11) and to reproduce the programming current (Iprog) for driving an emissive element (14). The display display device (6) is further arranged to execute a calibration phase wherein a calibration voltage (Vcal) is applied at each column electrode (11) before the programming current (Iprog) is applied.
