Abstract
Approaches for achieving low luminance on self-emissive displays, such as by reducing pixel current or applying a static pixel mask, can result in image uniformity issues or an abrupt change in brightness that may be perceived as flicker. Systems and methods are described that can address this by temporally modulating the intensity of a pixel mask. For example, instead of instantaneously deactivating a subset of pixels, a system can progressively reduce the luminance of designated pixels over a configurable period spanning multiple display frames. This may be achieved by iteratively applying a decreasing luminance multiplier to the masked pixels until their intensity approaches or reaches a target minimum, such as zero, creating a fading effect. This process can convert an abrupt change in screen luminance into a gradual transition, which may mitigate the perception of flicker and promote a smoother visual experience when entering or exiting low-brightness display modes.
