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

The present disclosure is directed to systems and methods of transferring bulk data, such as OLED compensation mask data, generated by a source device to a sink device using a high-bandwidth embedded DisplayPort (eDP) connection contemporaneous with an ENABLED Panel Self-Refresh (PSR) mode. Upon ENABLING the PSR mode, the source control circuitry causes the source transmitter circuitry, the sink receiver circuitry, and the eDP high-bandwidth communication link to remain active rather than inactive. The source control circuitry generates one or more data transport units (DTUs) having a header portion that contains data indicative of the presence of a bulk data payload and the non-display status of the bulk data payload carried by the DTUs.

Panel self-refresh (PSR) transmission of bulk data

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 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.
