METHOD OF DRIVING AN ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE AND DISPLAY DEVICE SUITABLE FOR SAID METHOD

摘要

This invention relates to a method of driving a display device (8) comprising a layer of organic electroluminescent material (4, 5), said layer being sandwiched between an anode (5) comprising a plurality of separated anode segments (5') and a cathode (6), said method comprising the steps of dividing the anode segments (5') into N subgroups (5a, 5b), each anode segment in each subgroup being surrounded by anode segments which are not members of the same subgroup, dividing an image signal IStot into corresponding N subgroups IS1, IS2, ... ISN, so that the i:th subgroup comprises the information which is intended to be fed to the anode segments of the corresponding i:th anode segment subgroup, , and, during a first time period t1, feeding a first subgroup (i=1) of said image signal IS1 to a corresponding first subgroup of first anode segments (5a), meanwhile holding all other anode segments at essentially equal potentials. This invention also relates to a device for use in the above method.
