Abstract: This disclosure provide various techniques for tracking emission profiles on an electronic display. An emission profile may be applied to the electronic display in order to illuminate certain pixels and deactivate (e.g., turn off) certain pixels in the electronic display to facilitate refreshing (e.g., programming with new image data) the deactivated pixels. A real-time row-based average pixel level or average pixel luminance calculation architecture may track the one or more EM profiles to accurately model EM profile behavior, which may enable accurate calculation of the average pixel level or average pixel luminance of the electronic display at any one point in time. The accurate average pixel level or average pixel luminance calculations effectuated by the EM profile tracking may be used to reduce the IR drop, improve real-time peak-luminance control, and improve the performance of under-display sensors, among other advantages.

Abstract: A switch control circuit comprises a comparison branch and a feedback branch. The comparison branch controls the turning off of the second power switch in the power conversion circuit based on the polarity of the voltage difference between the common node and the first voltage. The feedback branch generates a feedback signal based on the polarity of the first signal after the second power switch is turned off and a delay of the first duration and adjusts the first voltage. The first signal can be a voltage difference or the voltage of the common node. If the polarity of the first signal is positive, the first voltage is reduced to make the comparison branch turn off the second power switch earlier. If the polarity of the first signal is negative, the first voltage is increased to make the comparison branch delay the turning off of the second power switch.
