Abstract: Systems and methods described herein may utilize a non-linear scaling relationship to scale brightness of selective portions of the display in a manner that reduces or eliminates perceivable banding effects. By non-linearly controlling changes in brightness of the display, a viewer may perceive a more uniform, linear dimming towards the relatively dimmer region without perceiving banding, leading to improved user experience when viewing the electronic display.

Abstract: In a display characterized by regions with different pixel responses due, for example, to local pixel density variation, voltage-to-luminance matching may be non-universal. Therefore, in order to avoid visual artifacts that may hinder a desired visualization of displayed content, it may be advantageous to compensate the different gamma responses. In some cases, such as with electronic devices having a single pixel density across the display, optical calibration may be performed to determine voltage-to-luminance matching. However, in electronic devices with local pixel density variations, it may be disadvantageous to perform optical calibrations for each region with a different pixel density. Instead of using two distinct gamma curves which may include dedicated optical calibration, a global nonlinear scaler (GNLS) compensation may be applied.

Abstract: Embodiments herein provide various apparatuses and techniques to efficiently mitigate front-of-screen (FoS) artifacts that may occur due to voltage fluctuations due to alternating current (AC) or direct current (DC) mechanisms that may occur in a variety of pixel types. In one embodiment, emission profile awareness circuitry may be implemented to mitigate for FoS artifacts due to DC mechanisms. Two-dimensional (2D) digital compensation circuitry may address the DC portion of the voltage fluctuations by accounting for an emission profile applied to content displayed on an electronic display. In some embodiments, the 2D digital compensation circuitry may compensate for the AC portion of the voltage fluctuations by duplicating the AC voltage fluctuations via voltage error subtraction circuitry and voltage error accumulation circuitry.

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.
