Patent ID: 6927542

Claim:
A method of driving a display device having a layer of organic electroluminescent material, such as a light-emitting polymer or a small molecule compound, said layer being sandwiched between an anode and a cathode, said anode comprising a plurality of separated anode segments, the method comprising: dividing the anode segments of said display device into a plurality of anode subgroups, each anode segment in each anode subgroup being surrounded by anode segments that are not members of the same anode subgroup, essentially each anode segment of the display device being a member of one of said anode subgroups; dividing an image signal, comprising all information necessary to display a full and complete picture on said display, into a plurality of image signal subgroups corresponding in number to the plurality of anode subgroups, such that each image signal subgroup of the plurality of image signal subgroups comprises the information intended to be fed to the anode segments of a respective anode subgroup; and during a first time period, feeding a first image signal subgroup of said image signal subgroups to a corresponding first anode subgroup of the plurality of anode subgroups while holding all anode segments, not belonging to said first anode subgroup and surrounding any anode segment belonging to said first anode subgroup at essentially equal potentials.
