    Abstract: The present disclosure is directed to systems and methods of optimizing display image quality on display devices having a plurality of display power modes. Each power mode has associated therewith a respective baseline allowable percentage of distorted pixels and a baseline first relationship between an original pixel value and boosted pixel value. Display control circuitry determines a baseline second relationship using the baseline percentage of distorted pixels and the baseline first relationship. The display control circuitry selects a plurality of test distorted original pixel values and determines a respective test first relationship. Using the test distorted original pixel value, the respective test first relationship, and the baseline second relationship, the display control circuitry determines a respective PSNR and value indicative of the change in display image quality for each of the test distorted original pixel values.

    Abstract: Methods and apparatus relating to Organic Light Emitting Diode (OLED) compensation based on protected content are described. In an embodiment, secure memory stores data that is only accessible by trusted logic. Display controller logic circuitry updates pixel values to be stored in the secure memory based on a plurality of frames. The display controller logic circuitry allows access by untrusted software to the updated pixel values after a first number of updates to the pixel values stored in the secure memory. Other embodiments are also disclosed and claimed.

    Abstract: The present disclosure is directed to systems and methods for reducing display image power consumption while maintaining a consistent, objectively measurable, level of image distortion that comports with a display image quality metric. Raw image data is converted to an HSV format. “V” values are extracted from the HSV format raw image data and a histogram generates a plurality of “V” values. HSV format raw image data is provided to at least one layer of a trained CNN to extract a plurality of features. The plurality of “V” values and the plurality of features are provided to an AI circuit to generate a plurality of distortion class value pairs. Each of the distortion class value pairs is weighted based on proximity of display image distortion and the display image quality metric. The distortion class pair providing a display image distortion close to the display image quality metric is applied to the raw image data to generate the display image data.

    Abstract: Example display power management control circuitry is to determine a baseline image quality parameter associated with a baseline display power mode based on: a baseline first relationship parameter associated with a first relationship between original and boosted pixel values; a baseline percentage of pixels having a color value; and a baseline second relationship parameter associated with a second relationship between the numbers of original pixel values and boosted pixel values; determine a value of a subsequent first relationship parameter based on an adjusted second relationship parameter and a second percentage of pixels having the color value; determine a second image quality parameter associated with the subsequent first relationship parameter, the adjusted second relationship parameter, and the second percentage of pixels; and select the subsequent first relationship parameter and the adjusted second relationship parameter based on comparing the second image quality parameter to the baseline image quality parameter.
