摘要： This document describes techniques for color correction using a sensor to reduce color distortions of a camera under a display of a computing device. A correction module of the computing device may determine a color correction used to improve content captured by a camera utilizing, in part, a sensor (e.g., a camera, ambient light sensor, and so forth) positioned underneath the display. The sensor may detect ambient light over time that is modified as it travels through the display, producing color distortions. The sensor may also detect a composite light over time that includes calibration light emitted by the display and ambient light. The correction module may compare the ambient light and composite light to determine the color correction usable to improve both the content captured by the camera and a user experience.

摘要： 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.

摘要： High resolution displays, such as OLED displays, utilize complex driving circuits that can suffer from crosstalk. The crosstalk can affect the brightness of pixels in a row the display, which can be observed by a viewer as a crosstalk artifact. The severity of a crosstalk artifact may correspond to a contrast ratio of a high-contrast transition in which vertically adjacent pixels are sequentially driven by different driving signals during a scan. When a contrast ratio is above a maximum-perceptible contrast ratio, reducing the contrast ratio to the maximum-perceptible contrast ratio and can reduce, or eliminate, crosstalk artifacts. Disclosed herein are methods and devices that adjust pixels to reduce a crosstalk artifact without having a noticeable effect on contrast.
