Abstract:
Foldable displays may have portions folded into a folded configuration. Each folded portion may be observed by a user at a different viewing angle. As such, folding-artifacts may appear in the displayed image as a result of the different viewing angles. For example, a perceptible color difference and/or a perceptible brightness difference may appear between folded portions. Disclosed here are systems and methods to create compensated images that when displayed reduced the folding artifacts. The creation may include sensing a viewing angle for each portion and determining adjustments for pixels in each portion using a display model. The display model may be created by measuring color and brightness of pixels for various folded configurations, view-points and/or viewing angles.
