A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a backlight unit. The backlight unit may include a printed circuit board, a plurality of light-emitting diodes mounted on the printed circuit board, at least one light spreading layer formed over the printed circuit board that spreads light received from the plurality of light-emitting diodes, a partially reflective layer formed over the at least one light spreading layer, a color conversion layer formed over the partially reflective layer, a collimating layer formed over the color conversion layer, a brightness enhancement film formed over the collimating layer, and a diffuser formed over the brightness enhancement film. The at least one light spreading layer may include two light spreading layers with elongated protrusions that are rotated relative to each other.

Abstract:
Electronic devices and methods for compensating for noise in a display that includes sensing a current in a sensing channel of the display. Compensating for the noise also includes sensing an observation current from noise in an observation channel of the display and scaling the observation current to generate a scaled observation current. The scaled observation current is subtracted from the sense current to generate a compensated output. The compensated output is used to drive compensation operations of the display based at least in part on the compensated output to reduce effects of the noise.

G09G 3/00
Abstract:
Electronic devices and methods pertain to reducing artifacts resulting from a thermal profile preexisting a boot up of an electronic device are disclosed. Scanning driving circuitry of the electronic device scans at least a portion of one or more pixels of an active area of a display using a boot up scan before a boot up sequence of at least a portion of an electronic device completes. The results of the boot up scan are stored in local buffers and transferred to one or more processors upon connection to the one or more processors. The results of the boot up scan cause the one or more processors to modify image data to reduce or eliminate artifacts that may result during boot up due to thermal profiles or other parameters that may cause artifacts.

Abstract:
An electronic device that includes a display is provided. The display may have a brightness that is controlled using a series of cascaded digital-to-analog converter circuits. The display may be calibrated at a series of predetermined display brightness settings. For display brightness settings that fall between two consecutive display brightness settings in the series of predetermined display brightness settings, voltage interpolation operations may be performed to obtain the corresponding display brightness settings. Performing voltage interpolations instead of digital brightness setting interpolation helps minimize luminance jumps and unexpected color shifts when adjusting the brightness of the display.
