Embodiment Construction

[0028] An electronic device may have a display and a light sensor integrated into the layers of the display. exist figure 1 Exemplary electronic devices with displays and display-integrated light sensors are shown in , 2, 3 and 4.

[0029] figure 1 The electronic device 10 has the shape of a laptop computer and has an upper housing 12A and a lower housing 12B with components such as a keyboard 16 and a touchpad 18 . Device 10 has a hinge structure 20 to allow upper housing 12A to rotate in direction 22 about an axis of rotation 24 relative to lower housing 12B. A display 14 is installed in the upper housing 12A. Upper housing 12A is placed in the closed position by rotating upper housing 12A, which may sometimes be referred to as a display housing or cover, about axis of rotation 24 toward lower housing 12B.

[0030] figure 2 An exemplary configuration of electronic device 10 is shown, where device 10 is implemented as a handheld device such as a cellular telephone, musi...

Abstract

An electronic device is provided with a display and a display-integrated light sensor. The display includes a transparent cover layer, light-generating layers, and a touch-sensitive layer. The display-integrated light sensor is interposed between the transparent cover layer and a display layer such as the touch-sensitive layer or a thin-film transistor layer of the light-generating layers. The light-generating layers include a layer of organic light-emitting material. The display-integrated light sensor can be implemented as an ambient light sensor or a proximity sensor. The display-integrated light sensor may be a packaged light sensor that is integrated into the display layers of the display or may be formed from light-sensor components formed directly on a display circuitry layer such as the touch-sensitive layer or the thin-film transistor layer.

Description

[0001] This patent application claims priority to US Patent Application 13 / 686,746, filed November 27, 2012, which is hereby incorporated by reference in its entirety. technical field [0002] This patent application relates generally to electronic devices, and more particularly to electronic devices having displays and light sensors. Background technique [0003] The electronic device often includes a display. For example, cellular telephones and portable computers often include displays for presenting information to users. [0004] Electronic devices also often include light sensors. For example, an electronic device may include an ambient light sensor that senses the amount of light in the environment surrounding the device. The brightness of a displayed image generated by a display is sometimes adjusted based on the amount of ambient light. For example, in bright sunlight, the display brightness can be increased, while in a dark room, the display brightness can be dec...
