  • Patent number: 10657901
    Abstract: Varying electrical currents are selectively applied to each pixel within an OLED display to create desired images. High applied electrical currents to groupings of nearby pixels create high luminance features, while low applied electrical currents to groupings of nearby pixels create low luminance features. A combination of a high luminance and low luminance features may be present on the OLED display. Pulse-width modulation (PWM) is often used to increase the current applied to the OLED display by modulating the applied current, particularly when creating low luminance features. The presently disclosed systems and methods detect a gray portion of an image to be presented, and select PWM independently of peak luminance based on the detected gray portion. The allows the OLED display to display low-luminance features at high quality, even when high-luminance features are also present within a frame.
