Abstract
Circuitry may control and/or drive the brightness and/or luminance of pixels within displays. For example, an AR head-mounted display (HMD) may include and/or represent circuitry, such as a driver unit, that controls and/or drives the brightness and/or luminance of a perceptual quantizer (PQ) and/or gamma display. In one example, the circuitry may implement 8-bit counters to control the brightness and/or luminance of pixels within the PQ or gamma display. Unfortunately, such 8-bit counters may fail to enable the display to accurately reproduce perceptual brightness and/or luminance consistent with and/or under the Barten sensitivity curve and/or model. In another example, the AR HMD may include and/or represent a linear driver unit that controls and/or drives the brightness and/or luminance of a linear display via counters consisting of more than 8 bits. Unfortunately, implementing 12-bit counters may cause some display technologies to consume too much electrical and/or compute power in AR HMDs. To improve the perceptual brightness and/or luminance reproduced by the display without consuming so much electrical and/or compute power, the apparatuses, systems, and/or methods disclosed herein may utilize 12-bit counters that are split into multiple planes and/or segments.
