According to one embodiment, a display device includes a display area, a plurality of sensor electrodes and a shield electrode. The display panel includes a first substrate, a second substrate opposed to the first substrate, a liquid crystal layer sealed between the first substrate and the second substrate, a pixel electrode, and a counter-electrode. The plurality of sensor electrodes are arranged to surround the display area. The shield electrode is arranged between the plurality of sensor electrodes and the pixel electrode or the counter-electrode located closest to a boundary between the display area and a non-display area surrounding the display area, in planar view. A predetermined reference voltage is applied to the shield electrode.

A computing device, such as a wearable device, may include a light source and a photodetector array. The photodetector array may be used to determine a touch event of a user that occurs during a time interval. A subset of the plurality of photodetectors associated with the touch event may provide detection signals at each of a plurality of times within the time interval, which may be aggregated to obtain a time series of aggregated detection signals. Biometric data of the user may be generated, based on the time series of aggregated detection signals.

An electronic watch includes a housing and a crown assembly including a rotatable actuation member. The rotatable actuation member includes a knob external to the housing and configured to receive a rotational input and a shaft assembly coupled to the knob and positioned at least partially within the housing, the shaft assembly defining a sensing surface configured to rotate in response to the rotational input. The electronic watch further includes an optical sensing system configured to detect the rotational input, the detecting including directing light onto the sensing surface, receiving reflected light from the sensing surface, and producing a signal corresponding to a rotational motion of the sensing surface, the signal based at least in part on an interference between the light directed onto the sensing surface and the reflected light.

The present disclosure relates to techniques for accessing modes of operation and techniques for providing an alarm interface for electronic devices. In some embodiments, a device detects that a battery is being charged and that the device is oriented in a predefined orientation. In accordance with the detection that the battery is being charged and that the device is oriented in the predefined orientation, the device activates a predefined mode of operation. In some embodiments, a device displays a first user interface object in a first color, and, at a predetermined time, the device displays the first user interface object in a second color and displays an option for dismissing an alarm, wherein the option for dismissing is displayed as a second user interface object located at a portion of a display of the device proximate to a hardware button of the device.

To prevent an erroneous operation and improve operability, a button device and a timepiece including the button device are provided. The button device includes: a cylindrical first guide protector 11 protruding from the lateral face of a wristwatch case 1; and a first button 12 disposed in the first guide protector 11 to be slidable inward and outward of the wristwatch case 1. The first button 12 includes a first button head 13 disposed in the first guide protector 11, and a first button shaft 15 passing through a first through hole 14 of the wristwatch case 1. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1. The first guide protector 11 protects the outer periphery of the first button head 13, and this prevents accidental and erroneous operation of the first button 12. The first button head 13 is inclined obliquely upward relative to the lateral face of the wristwatch case 1, and this allows the user to easily place a fingertip on the outer end face of the first button head 13, and so improves the operability of the first button 12.

An electronic device, such as a watch, has a housing to which a carrier is attached. The carrier has a first surface interior to the electronic device, and a second surface exterior to the electronic device. A set of electrodes is deposited on the exterior surface of the carrier. An additional electrode is operable to be contacted by a finger of a user of the electronic device while the first electrode is positioned against skin of the user. The additional electrode may be positioned on a user-rotatable crown of the electronic device, on a button of the electronic device, or on another surface of the housing of the electronic device. A processor of the electronic device is operable to determine a biological parameter of the user based on voltages at the electrodes. The biological parameter may be an electrocardiogram.
