Abstract

A passive matrix organic light emitting display system includes a plurality of pixels configured for emitting light when energized by one of a plurality of row electrodes and one of a plurality of column electrodes. The display system also comprises a plurality of column drivers configured for energizing the plurality of column electrodes. The display system also comprises a plurality of row drivers configured for energizing the plurality of row electrodes. At least two of the plurality of row drivers are configured to simultaneously energize at least two of the plurality of row of electrodes. A method of displaying information on a passive matrix organic light emitting display system is also disclosed.

Claims

a plurality of column drivers configured for energizing the plurality of column electrodes;

a plurality of row drivers configured for configured for energizing the plurality of row electrodes;

wherein at least two of the plurality of row drivers are configured to simultaneously energize at least two of the plurality of row of electrodes, wherein the two row drivers include a first row driver and a second row driver, wherein the column driver includes a first set of column drivers and a second set of column drivers, wherein the first set of column drivers do not energize pixels energized by the second row driver and energize pixels energized by the first row driver.

2. The display system of claim 1 wherein at least three of the plurality of row drivers are configured to simultaneously energize at least three of the plurality of row electrodes.

3. The display system of claim 1 wherein at least two of the plurality of row drives are configured to be activated at the same time.

4. The display system of claim 1 wherein at least two of the plurality of row drivers are active per duty cycle of the display system.

5. The display system of claim 1 wherein at least two of the plurality of row drivers are multiplexed.

6. The display system of claim 3 wherein the at least two row divers are on the same side of the display.

7. The display system of claim 6 wherein each of the plurality of pixels include at least four of the plurality of column electrodes.

8. The display system of claim 7 wherein each of the plurality of pixels include at least eight of the plurality of column electrodes.

9. The display system of claim 8 wherein each of the plurality of column electrodes are in electrical contact with only one of the plurality of pixels.

10. A method of displaying information on a passive matrix organic light emitting diode display system comprising a first column driver having a first column electrode, a second column driver having a second column electrode, a first row driver having a first row electrode, a second row driver having a second row electrode, a first pixel and a second pixel, the first and second pixel being disposed on a single substrate, the method comprising:
