Selecting adjustment for OLED drive voltage
First Claim
Patent Images
1. A method for selecting an adjustment for at least one drive voltage used to drive an OLED display to reduce power consumption, comprising:
- a) operating the display to produce a calibration curve which depicts the drive voltage versus current or luminance; and
b) selecting the adjustment for the drive voltage based upon the calibration curve so as to reduce the power consumed by the OLED display while maintaining desired luminance throughout the lifetime of the OLED display.

Abstract
A method for selecting an adjustment for at least one drive voltage used to drive an OLED display to reduce power consumption including operating the display to produce a calibration curve which depicts the drive voltage versus current or luminance, and selecting the adjustment for the drive voltage based upon the calibration curve so as to reduce the power consumed by the OLED display while maintaining desired luminance throughout the lifetime of the OLED display.

4. A method for selecting an adjustment for a drive voltage used to drive at least three different color channels in an OLED display to reduce power consumption, comprising:
-
a) operating the display to produce a calibration curve for each color channel which depicts the drive voltage versus current or luminance; and
b) selecting the adjustment for the drive voltage based upon the calibration curve which produces the least desirable drive voltage so as to reduce the power consumed by the OLED display while maintaining desired luminance throughout the lifetime of the OLED display. - View Dependent Claims (5, 6)
