Patent ID: 6975291

Claim:
A method for generating an uniform luminosity for an organic light emitting diode display device that has a plurality of scanning lines, a plurality of data lines, a plurality of luminous materials driven by the scanning lines and the data lines, a data line driver circuit to provide data signals to the data lines, and a scanning line driver circuit which has a scanning cycle T to provide scanning signals according to a selected scanning method to all scanning lines, comprising steps of: obtaining the luminous efficiency Pi of every luminous material and calculating the least common multiple Pm thereof based on the luminous efficiency Pi; dividing evenly the original scanning cycle T of the scanning line driver circuit by the least common multiple Pm to obtain Pm sub-scanning cycles to allow the scanning line driver circuit to scan sequentially and respectively all of the scanning lines in the Pm sub-scanning cycles; and providing data signals by the data line driver circuit to the data lines in every scanning cycle based on the every luminous efficiency Pi and the least common multiple Pm to drive every luminous material and driving every luminous material Pm/Pi times in the scanning cycle T, whereby uniform luminosity is generated.
