Embodiment Construction

[0020] Electronic devices such as cellular telephones, media players, computers, set-top boxes, wireless access points, and other electronic devices may include displays. Displays may be used to present visual information and status data and / or may be used to collect user input data.

[0021] figure 1 An exemplary type of electronic device that may be provided with an ambient light adaptive display is shown. Electronic device 10 may be a computer, such as a computer integrated into a display such as a computer monitor, a laptop computer, a tablet computer, a somewhat smaller portable device such as a wrist watch device, a pendant device, or Other wearable or miniature devices, cellular phones, media players, tablets, gaming devices, navigation devices, computer monitors, televisions, or other electronic devices.

[0022] Such as figure 1 As shown, device 10 may include a display such as display 14 . Display 14 may be a touch screen including capacitive touch electrodes or ...

Abstract

An electronic device may include a display having an array of display pixels and having display control circuitry to control operation of the display. The display control circuit can operate the display in different modes. In paper mode, the display control circuitry can use the stored spectral reflectance data to adjust the display colors so that the colors appear as they would appear on printed paper. In a low light mode when ambient light levels are below a threshold, the light emitted from the display can be adjusted to mimic the appearance of an incandescent light source. In a bright light mode when ambient light levels exceed a threshold, the light emitted from the display can be adjusted to maximize readability in bright light. The target white point of the display can be adjusted based on what mode the display is operating in.

Description

[0001] This application claims priority to U.S. Patent Application No. 14 / 673,667, filed March 30, 2015, and U.S. Provisional Patent Application No. 62 / 096,188, filed December 23, 2014, which are filed at This is incorporated herein by reference in its entirety. technical field [0002] The present application relates generally to electronic devices with displays, and more particularly, to electronic devices with 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, white paper will appear white to the human eye even when illuminated under different ambient lighting conditions. [0004] Conventional displays generally do not take into account different ambient lighting conditions or the chromatic adaptation of the human visual system. As a result, users may p...
