Abstract:
1. A video display device comprising: a voltage correction table; a calibration unit configured to generate data in the voltage correction table comprising a column resistance correction table, said data being derived based, at least in part, on a plurality of reference currents; at least one driver configured to drive at least one organic light emitting diode at a voltage defined, at least in part, by the voltage correction table, wherein driver comprises at least two capacitors, wherein the first of the at least two capacitors is chargeable to a first voltage to drive current across an organic light emitting diode in a first row of the video display device, and wherein the second of the at least two capacitors is chargeable to a second voltage to drive current across an organic light emitting diode in a second row of the video display device.
