A smartwatch assembly may include a dial portion having a plurality of apertures extending therethrough and a circuit board having a plurality of LED modules disposed thereon. The plurality of LED modules may be oriented to emit light toward the plurality of apertures of the dial portion. The circuit board may include a control module configured to illuminate the plurality of LED modules in response to an alert and a communication module configured to interface with an electronic device wirelessly and to receive the alert. Methods of making a smartwatch assembly may include disposing a dial portion having a face plate and a plurality of hour-mark apertures extending through the face plate in a watch casing and disposing a circuit board having a plurality of LED modules disposed thereon in a watch casing, the plurality of LED modules corresponding to the plurality of hour-mark apertures.

According to one embodiment of the preset specification, a method for controlling a wearable device for displaying visual information on a first display area and on a second display area can comprises the steps of: detecting that the wearable device has been changed to a charging state; displaying first visual information on a first display area; displaying second visual information on a second display area; detecting an event relating to a first application while the wearable device is in a charging state; and displaying, on the second display area, third visual information relating to the first application. At this time, the first visual information of the first display area can be displayed on a display unit of the wearable device, and the second visual information of the second display area can be displayed on the basis of a light source projected outside of the wearable device.

An electronic device includes a wristband comprising a first main surface and a second main surface disposed oppositely; a first display panel and a second display panel which are disposed on the wristband and at least partially facing each other. The first display panel is disposed on the first main surface and the second display panel is a flexible display panel and disposed on the second main surface.

A wearable device may include: an analog watch unit that includes a time indicating unit that indicates time, and a drive unit that drives the time indicating unit; a touch screen that senses an input for adjusting the drive unit; and a control unit that controls the drive unit in response to the sensed input.

Sleep alerts associated with an alarm can be scheduled using a first electronic device. Once scheduled, data can be collected from a second electronic device. This data can be used to determine an appropriate device, other than the first electronic device, at which the sleep alert can be presented. Once determined, the information can be sent to the appropriate device for presenting the sleep alert.

An embodiment of the present invention provides a method for presenting a watch face. The method includes: obtaining first context information and second context information, where the first context information is used to determine a watch face style of the smartwatch, and the second context information is used to indicate dressing information of a user; determining the watch face style of the smartwatch according to the first context information; and presenting a watch face pattern of the smartwatch according to the watch face style and the second context information.

A method of controlling a watch-type mobile terminal including a bezel, the method includes executing a contact application stored in a memory; outputting a contact list on a display unit when the contact application is executed; sensing a touch input signal on the display unit, wherein the touch input signal is a drag touch input on the display unit in a first direction; scrolling the contact list to search for a specific contact regardless of the drag touch input's speed; sensing a rotation input on the bezel, wherein the rotation input is an input for rotating the bezel with a speed in a second direction, further the first direction is different from the second direction; and controlling a scroll pop-up for searching for the specific contact to be output on the contact list of the contact application if the speed of the rotation input is faster than a first predetermined speed.

Past and future time visualization enables a user to visualize the amount of time that has passed or when a future time will be reached. By triggering past time visualization, a device displays an arced line from a previously selected time to the present time. By triggering future time visualization, a device displays an arced line from the present time to a selected future time. In some embodiments, when the future time is reached, an alarm is triggered.
