A method and system for adjusting luminance in a display device including displaying an image with saturated colors, and adjusting luminance settings of sub-pixels so that a relative luminance ratio between full white color and any fully saturated color is within approximately 25 percent of a reference relative luminance ratio between the full white color and the same fully saturated color in an equivalent display device including red, green and blue sub-pixels.

Luminance adjustment in a display unit

Portable devices () that include displays () and are used in widely ranging ambient light conditions use selectable or adjustable optoelectronic input/output compensation functions to drive their displays. According to certain embodiments, a camera () or a light sensor () is used to measure the ambient light level, and an optoelectronic input/output compensation function that is specifically chosen based on the measured ambient light condition is used to drive the display. Furthermore, according to certain embodiments, the optoelectronic input/output compensation function is selected based on whether a display backlight () is turned on or off.

Electronic device with optoelectronic input/output compensation function for a display

Disclosed are methods and devices for color compensation of a display having a translucent display cover applied to an outside surface of the display. A method may include characterizing a color shift due to the translucent display cover for when there is rendering of an image on the display and compensating for the color shift when rendering an image on the display. The method further may include measuring the color shift induced by the color of the finish, and as described below compensating the red, green, and blue (RGB) levels of the display so that the display image may be presented to the user as originally intended. In this way, the image quality may be substantially optimized for viewing regardless of the lens/cover surface color.
