Abstract: Display systems, media, and methods. Pixels of an image former form an image. Each pixel has a first color element to propagate a first amount of a first light having a first wavelength, based on a first electrical stimulus, and a second color element to propagate a second amount of a second light having a second wavelength, based on a second electrical stimulus. A display surface presents the image across a plurality of display surface locations. A processor executes instructions to scale the first electrical stimulus of each pixel of the image former by a first light scale factor, scale the second electrical stimulus of each pixel of the image former by a second light scale factor, and apply a pixel shading map to the image former to independently adjust, for each pixel of the display, the first amount relative to the second amount.

Abstract: Embodiments are directed to electronic devices that include a behind-display imaging device and at least one birefringent layer positioned between the behind-display imaging device and a cover layer of the electronic device. In some instances, the birefringent layer(s) may be configured to obscure the presence of light-transmitting regions of the display in an imaging region of the display. Additionally or alternatively, the birefringent layer(s) may help to reduce image artifacts in images captured by the imaging device.

Abstract: A display system for color correcting a display.

The synchronization signal provides a timing to block light from the display screen for a display update duration corresponding to a subset of pixels of the display screen.
