A relay is disposed inside the master control circuit board. Contacts of the relay respectively extend and are fixed on a surface of the master control circuit board by using leads. Therefore, a problem that a conventional timer movement is fixedly welded on a circuit of a timer module can be resolved.

An electronic device includes a display layer comprising emission areas that provide different colored light, respectively, and a non-emission area adjacent thereto. A sensor layer comprises a first sensing insulating layer, a first conductive layer, a second sensing insulating layer, and a second conductive layer and comprising mesh lines extending in first and second directions. The mesh lines comprise a first line extending in the first direction, second and third lines extending in the second direction from opposite sides of the first line, and a fourth line spaced apart from the third line in the first direction and extending in the second direction from the first line. A reinforcing pattern is disposed on inner areas defined by the first line and each of the second to fourth lines, respectively. The reinforcing pattern protrudes from portions of the first to fourth lines that define each inner area of the inner areas.

An electronic device such as a watch may include a display and a light sensor located behind the display. The light sensor may be used to measure the color of external objects. During color sampling operations, the display may emit light towards the external object in front of the display while the light sensor gathers color measurements. The display may emit light of different colors and the light sensor may detect an amount of reflected light for each color, which in turn may be used to determine the color of the external object. The control circuitry may use a watch-band-specific algorithm to determine the color of watch bands and may use a clothing-specific algorithm to determine the color of clothing. The control circuitry may display the color on the display so that the face of the watch matches the user's clothing or matches the user's watch band.

A wearable electronic device according to an embodiment of the present disclosure comprises: a display that forms a front surface of the wearable electronic device; and a frame part that surrounds the display and forms at least a part of the exterior of the wearable electronic device, wherein the frame part comprises a fastening part to which a strap for assisting wearing of the wearable electronic device is coupled, the fastening part comprises a first coupling part, and a second coupling part spaced apart from the first coupling part by a specified distance, the first coupling part comprises a first groove into which a fastening structure of the strap can be inserted, and a second groove to which the fastening structure of the strap can be fixed, the second coupling part comprises a fourth groove to which the fastening structure of the strap can be fixed, and the fastening structure of the strap may be at least inserted into the first groove and fixed to the second groove and the fourth groove. According to various embodiments of the present disclosure, since a guide groove is provided in a fastening part of a frame part of a wearable electronic device, a user can easily fasten a strap without determining an exact position thereof, and it is possible to prevent and/or reduce damage to the wearable device or the strap that occurs in the process of determining the exact position of a hole provided in the wearable electronic device.

A display assembly includes a three-dimensional display cover defining an internal volume. The three-dimensional display cover includes a central portion and a peripheral portion. The peripheral portion extends around a periphery of the internal volume. The display assembly includes a first display and a second display. The first display is disposed within the internal volume of the three-dimensional display cover and is visible through the central portion of the three-dimensional display cover. The second display is disposed within the internal volume of the three-dimensional display cover and extends around at least a portion of a periphery of the first display. Furthermore, the second display is visible through the peripheral portion of the three-dimensional display cover.

An electronic device may have rigid members such as links in a strap that are joined by rotating joints. The joints may include friction hinges. In a head mounted device, straps may be folded for storage within an interior region in the housing of the head mounted device. A strap coupled to a wristwatch may have portions that fold to hide components mounted on the strap. A strap with two parallel strap portions may be configured to serve as a support for a cellular telephone or other device with a display. A strap can also be configured to tilt a display that is coupled to the strap to a desired viewing angle relative to a user's wrist. An electronic device may have multiple support structures that are joined by a friction hinge. The support structures may be used to clamp the device on a user's finger.

An apparatus for a wearable device with expandable display strips, the apparatus includes a first layer with a first display panel coupled to a second layer with a second display panel, where the first display panel can extend and retract over a top surface of the second display panel. The apparatus also includes a first gear and rack mechanism coupled to the top surface of the second display panel and a bottom surface of the first display panel, where the first gear and rack mechanism is configured to extend and retrack the second layer with the second display relative to the first layer with the first display. Furthermore, the first layer and the second layer are arranged in a concentric manner.

An electronic device includes a main body; a display; an electrode positioned in the main body to be in contact with a body of a user; and a processor operatively connected to the display and the electrode, wherein the processor is configured to: identify an electrical value measured through the electrode, determine whether to control a performance of the electronic device by comparing the electrical value and a preconfigured control-requiring value, identify whether the electrical value is within at least one of a first range and a second range which are classified and configured in advance, based on identifying that the electrical value is within the first range, control the performance of the electronic device to a first level, and based on identifying that the electrical value is within the second range, control the performance of the electronic device to a second level, and wherein the performance of the electronic device controlled to the second level is relatively lower than the performance of the electronic device controlled to the first level.
