Embodiment Construction

[0024] Electronic devices such as cellular phones, media players, computers, set-top boxes, wireless access points, and other electronic devices may include displays. The display can be used to present visual information and status data and / or can be used to collect user input data.

[0025] figure 1 The types of exemplary electronic devices that can be provided with an ambient light adaptive display are shown. The electronic device 10 may be a computer, such as a computer integrated in a display such as a computer monitor, a laptop computer, a tablet computer, a slightly smaller portable device such as a wrist watch device, a hanging device, or Other wearable or micro devices, cellular phones, media players, tablets, gaming devices, navigation devices, computer monitors, televisions, or other electronic devices.

[0026] Such as figure 1 As shown, the device 10 may include a display such as a display 14. The display 14 may be a touch screen containing capacitive touch electrodes...

Abstract

An electronic device may include a display having an array of display pixels and having display control circuitry that controls operation of the display. The display control circuit can adaptively adjust display output based on ambient lighting conditions. For example, in cooler ambient lighting conditions, such as those dominated by daylight, the display may use a relatively cool white to display neutral colors. When the display is operated in warmer ambient lighting conditions, such as those dominated by indoor light sources, the display may use a relatively warm white to display neutral colors. Adapting to ambient lighting conditions ensures that the user does not perceive a color shift as the user's visual color adapts to different ambient lighting conditions. Adapting images in this way may also have a beneficial effect on human circadian rhythms by displaying warmer colors at night.

Description

[0001] This application claims priority from U.S. Patent Application No. 14 / 673,685, filed on March 30, 2015, and U.S. Provisional Patent Application No. 62 / 080,934, filed on November 17, 2014, which are filed in This is incorporated by reference in its entirety. Technical field [0002] The present application relates generally to electronic devices having displays, and more specifically, to electronic devices having displays that adapt to different ambient lighting conditions. Background technique [0003] The chromatic adaptation function of the human visual system allows humans to generally maintain a constant perceived color under varying ambient lighting conditions. For example, an object that appears red when illuminated by sunlight is also perceived as red when illuminated by indoor electric light. [0004] Conventional displays typically do not take into account different ambient lighting conditions or color adaptation of the human visual system. As a result, user...
