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: An electronic device may include an electronic display having multiple display pixels that display an image based on dithered image data. The electronic device may also include image processing circuitry that generates the dithered image data based on input image data and a threshold gray level that is greater than one. Generating the dithered image data may include replacing each gray level of the input image data that is less than the threshold gray level with either a zero gray level or the threshold gray level according to a dither pattern.

Abstract: An electronic device may include an electronic display having a gate-on-array (GOA) that generates gate signals in response to an activation signal, pixels that activate in response to a combination of the gate signals and data signals indicative of image data, and sensing circuitry. The sensing circuitry may measure a characteristic response of a gate signal a characteristic response of one or more pixels, or both and compare the characteristic responses to baselines. The electronic device may also include compensation circuitry that applies a compensation to the activation signal and/or to the image data based on the comparisons between the characteristic responses and the baselines.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may render different content layers that present different classes of content. The different classes of content may have different characteristics. As an example, a first class of content may be static content whereas a second class of content may be dynamic content. The different characteristics of each class of content may be leveraged to use a hybrid approach for content processing. The hybrid content processing may take advantage of different layers needing to be updated at different frequencies and may take advantage of sparse content in some of the layers.
