An electronic device can include a housing component that can define an interior surface and an exterior surface of the device, a metallic film deposited on the interior surface and extending at least partially onto the exterior surface, and a ceramic film deposited on the exterior surface and at least partially over a portion of the metallic film on the exterior surface. The ceramic film can be in electrical communication with a portion of the metallic film deposited on the interior surface to form an electrical pathway from the exterior surface to the interior surface.

A device capable of being used for a long time is achieved. A power supply, a connection method of a power supply, or a connecting member, for easy attachment and detachment and non-detachment when in use, is provided. A power supply, a connection method of a power supply, or a connecting member for easy replacement is provided. A highly designed power supply is provided. Power from a battery is supplied to an electronic device through a connecting member including a pipe, a spring, and a pair of pivots. The pair of pivots are electrically insulated from each other, and electrically connected to any one of a pair of electrodes of the battery. The electronic device into which the pair of pivots are inserted includes a pair of bearings capable of receiving power.

The present disclosure provides a display device, including: a display panel, a main circuit board, and a plurality of chip-on-films bonded between the display panel and the main circuit board. The wiring area is provided with a plurality of first binding regions; the plurality of first binding regions are distributed along the wiring area. The main circuit board is provided with a plurality of second binding regions which are corresponding to the first binding regions in a one-to-one manner. A shape of the main circuit board is the same as a shape of the wiring area. A first end of each chip-on-film is bonded to one corresponding first binding region; a second end of each chip-on-film is bonded to one corresponding second binding region.

An external battery device is implemented which can detachably engage with a smartwatch to thereby enable seamless battery replacement and smartwatch battery replenishment without having to remove the smartwatch from a user's wrist. The external battery device can be a bezel that aesthetically fits in a cut-out around a perimeter of the smartwatch's face and locks in place using, for example, a male-female connection mechanism. The external battery device includes a casing that functions as the bezel for the watch. The casing includes a channel inside which a rechargeable battery is positioned. The male connectors of the external battery device extend downward from a hole in the casing to engage with corresponding female receptacles on the smartwatch. In typical implementations, two different shapes of the male and female connection mechanisms may be used to provide a consistent manner in which the user connects the external battery device to the smartwatch.

An electronic timepiece has an antenna having a first conductor element connected to a feed, a second conductor element superimposed with the first conductor element in plan view, and a shorting element shorting the first and second conductor elements; a solar panel; a circuit board electrically connected to the feed; a connector electrically connecting the solar panel and the circuit board; and a case having a side wall and housing the antenna, solar panel, circuit board, feed, and connector. A through-hole through which a pivot passes is disposed to the antenna at a position different from the shorting element. The connector is disposed in plan view to a third area excluding from a first area surrounded by the side wall a second area defined by a line indicating a position one-third the distance from the center of the first or second conductor element to an outside circumference.

A fastening kit for a watch including at least one fastening device for fastening, according to a fastening method, at least one tube and for electrically connecting the at least one tube to a support.

A wristwatch band for a computerized watch base has a bracelet portion and a connector element. The bracelet portion extends in a length direction at least partially around a wrist of a wearer and has a power supply device to supply power to the computerized watch base. The connector element secures the computerized watch base to the bracelet portion. In the length direction, the bracelet portion may be discontinuous and terminate at first and second clasp ends. First and second clasp sections may be provided respectively at the first and second clasp ends of the bracelet portion, the first and second clasp sections releaseably connecting around the wrist of the wearer. Electrical connectors may be provided in each clasp section such that when the clasp is connected around the wrist of the wearer, an electrical connection is made from the first clasp end to the second clasp end.
