Methods, apparatus, systems, and articles of manufacture to control an aggressiveness of display panel power savings are disclosed. An example apparatus include a display panel, a display controller to adjust an image to be displayed by the display panel, and a power savings controller to access an image provided to the display controller, execute a machine learning model using the image as an input to generate an aggressiveness value, and provide the aggressiveness value to the display controller, the display controller to adjust the image based on the aggressiveness value.

Methods and apparatus to control an aggressiveness of display panel power savings and fidelity

Described are mechanisms and methods for applying Machine Learning (ML) techniques for power management at different levels of a power management stack. An apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may have a plurality of memory registers. The second circuitry may be operable to establish values for a plurality of features based on samples of values of the plurality of memory registers taken at one or more times within a range of time of predetermined length. The third circuitry may be operable to compare the plurality of features against a plurality of learned parameters for a reference workload.

Detection of known workload patterns

The present disclosure is directed to systems and methods of optimizing display image quality on display devices having a plurality of display power modes. An example apparatus includes processor circuitry to execute instructions to: determine a baseline allowable percentage of distorted pixels for a power mode of a display; determine a baseline first relationship between an original pixel value and a boosted pixel value for the power mode; determine a baseline second relationship based on the baseline allowable percentage and the baseline first relationship; select a plurality of test distorted pixel percentages; determine, for respective selected test distorted pixel percentages, a corresponding test relationship between an original pixel color value distribution and a boosted pixel color value distribution based on the baseline second relationship; determine, for respective test relationships, a respective test peak signal to noise ratio (PSNR); determine, for the respective test PSNRs, respective values indicative of the change in image quality for the test distorted pixel percentages; and select, as the operating distorted original pixel percentage value, one of the test distorted pixel percentages based on the values.

Power saving display having improved image quality

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.

Systems and methods of reducing display power consumption with minimal effect on image quality

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 &#x201c;V&#x201d; 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.

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.

The present disclosure is directed to systems and methods of reducing display image power consumption while maintaining image quality on display devices having a plurality of display power modes. Each display power mode has associated therewith a defined baseline value (K) first relationship. A display image includes a baseline percentage under-boosted pixels (X). Using the first relationship value (K) and the pixel percentage (X), a baseline second relationship value is determined (K). The value associated with the second relationship is adjusted to a first plurality of values. At each value, the value associated with the pixel percentage is adjusted to each of a second plurality of values. At each combination of second relationship value and pixel percentage, a respective first relationship value is determined. A first relationship value, second relationship value are selected to provide a reduced power consumption while maintaining image quality.
