OLED COLOR TUNING BY DRIVING MODE VARIATION

摘要

Techniques, devices, and systems are provided that allow for driving a device such as an OLED in various pulsed modes in which a momentary luminance greater than an apparent luminance at which the OLED is to be driven is used. The use of one or more pulsed modes allows for the lifetime of the OLED to be extended and reduces image sticking. Pulsed modes are also provided that allow for color tuning of the device by activating different portions of one or more emissive areas of the device.

主权项

1. A method of operating an OLED display device, the method comprising:
receiving an input signal indicating an apparent luminance to be generated by at least one OLED in the display during a first frame time; providing a first drive signal to the at least one OLED, the first drive signal comprising a waveform specifying an output for the at least one OLED during the first frame time, wherein the first drive signal produces a momentary luminance greater than the apparent luminance for at least a portion of the first frame time.
