==Original Abstract Submitted==

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. embodiments may pertain to techniques for applying a per-channel and band-global gamma-to-voltage compensation to reduce or minimize a relative luminance error amongst different responses of display regions.
