DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments of the present invention are described below to explain the present general inventive concept by referring to the figures. As those skilled in the art would realize, the described embodiments of the present invention may be modified in various different ways, all without departing from the spirit or scope of the present inventive concept.

It will be understood that although the terms “the first”, “the second”, etc. may be used herein to describe various components, these components should not be limited by these terms. These components are only used to distinguish one component from another. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

FIG. 1 is an exploded view of a watch according to an embodiment of the present invention. Referring to FIG. 1, a watch 100 may include a glass 190, a bezel 180, hands 170, a dial pad 160, a movement 150, a printed circuit board (PCB) 140, at least one of batteries 130 or 135, a case 120, and a case back 110. The watch 100 may be an embodiment of a wearable internet of things (IoT) device. The watch 100 may serve as a smart watch while maintaining an outer appearance of a conventional mechanical watch.

The PCB 140 having an inner diameter D2 and an outer diameter D3 may be shaped as a circle, a donut, or a C shape; however, it is not limited thereto. Even if it is shown in FIG. 1 that the dial pad 160 may be connected to the hands 170, the dial pad 160 may serve as a display device according to an embodiment of the present invention. The display device may be a TFT-LCD display, a LED display, an OLED display, an AMOLED display, or a flexible display.

The movement 150 may be shaped as a circle having a diameter D1 and may be disposed adjacent to the dial pad 160 and hands (for example, hour hands and minute hands, including second hands) 170 connected to the dial pad 160. Since the diameter D1 of the movement 150 may be smaller than the inner diameter D2 of the PCB 140, the movement 150 having the diameter D1 smaller than the inner diameter D2 may be sized and shaped to fit into a hole defined as the inner diameter D2 of the PCB 140. Therefore, the movement 150 may be inserted into a hole of the PCB 140.

According to an embodiment of the present invention, the movement 150 may be a mechanical movement for driving the hands 170 or an electronic movement for driving the hands 170.

The PCB 140 may include a plurality of integrated circuits (ICs) and passive elements (for example, a resistor, an inductor, or a capacitor) which may be disposed or integrated in a region RG between the inner diameter D2 and the outer diameter D3. The plurality of ICs may include an IC for a mobile payment, an IC for a health solution, an IC for a security solution, and/or an IC for an authentication solution; however, it is not limited thereto.

A first battery 130 may be disposed adjacent to the PCB 140 including the inner diameter D2 and the outer diameter D3 and may supply a first operating voltage to ICs disposed on the PCB 140. Therefore, the first battery 130 may supply the first operating voltage only to the PCB 140. According to an embodiment of the present invention, a diameter of the first battery 130 may be larger or smaller than the inner diameter D2 of the PCB 140.

According to an embodiment of the present invention, when the movement 150 is a mechanical movement, a clock function and a smart function of the watch 100 may be physically separated from each other, and accordingly, the watch 100 may serve as a clock using the mechanical movement 150 even though the first battery 130 for supplying the first operating voltage to the PCB 140 is discharged.

According to an embodiment of the present invention, when the movement 150 is an electronic movement, the watch 100 may further include a second battery 135, which may be electrically connected to the movement 150 and may not be electrically connected to the PCB 140, supplying a second operating voltage to the electronic movement 150. According to an embodiment of the present invention, a diameter of the second battery 135 may be larger or smaller than the inner diameter D2 of the PCB 140. Since the clock function and the smart function of the watch 100 may be physically separated from each other, the watch 100 may normally serve as a clock using the second battery 135 even though the first battery 130 for supplying the first operating voltage to the PCB 140 is discharged.

Even if it is shown in FIG. 1 that the second battery 135 may be disposed adjacent to the first battery 130, it is not limited thereto. According to an embodiment of the present invention, each of the batteries 130 or 135 may be a flexible battery. According to an embodiment of the present invention, each of the batteries 130 or 135 may be a battery of a rechargeable type.

According to an embodiment of the present invention, the bezel 180 may be mechanically connected to the case 120 including a crown 125 and may serve as an antenna for wireless communications. The bezel 180 may be connected to a wireless communications module mounted on the PCB 140 through a wire or a metal 121. The glass 190 connected to the bezel 180 may be replaced with a transparent display device 190.

Referring to FIGS. 1 to 3, a PCB 140A or 140B having an inner diameter D2 and an outer diameter D3 may include an application processor (AP) 141, a power management IC (PMIC) 142, a memory 143, a security module 144, a biological processor or bio-processor 145, a wireless communication module 146, and/or a display driver IC 147 disposed in a region RG between the inner diameter D2 and the outer diameter D3.

Although the ICs 141 to 147 disposed in the region RG between the inner diameter D2 and the outer diameter D3 on an upper surface of the PCB 140A or 140B are shown in FIGS. 2 and 3, at least one of ICs 141 to 147 may be disposed in the region RG between the inner diameter D2 and the outer diameter D3 on a lower surface of the PCB 140A or 140B according to an embodiment of the present invention.

Although passive elements (for example, a resistor, an inductor, or a capacitor) are not shown in the region RG between the inner diameter D2 and the outer diameter D3 of the PCB 140A or 140B in FIGS. 2 and 3, the passive elements may be disposed in the region RG on the upper surface of the PCB 140A or 140B and/or in the region RG on the lower surface of the PCB 140A or 140B.

The AP 141 may execute an application 141A for the smart function (for example, web-browsing, mobile payment, health solution, security solution, and/or authentication solution) used in the watch 100. The application 141A may refer to application software which may be executed on an operating system (OS). Even if one application 141A is shown in FIGS. 2 and 3, the application 141A may include applications for performing the smart functions as described above. The AP 141 may control an operation of each of the ICs 142 to 147.

The PMIC 142 may supply a corresponding operating voltage to each of ICs 141 and 143 to 147 using the first operating voltage supplied from the first battery 130.

The memory 143 may store data and programs (for example, OS and/or application(s)) to be used in the watch 100. The memory 143 may collectively represent a volatile memory and/or a non-volatile memory. The volatile memory may be a random access memory (RAM), a static RAM (SRAM), or a dynamic RAM (DRAM); however, it is not limited thereto. The non-volatile memory may be a read only memory (ROM), a flash memory, or a resistive RAM; however, it is not limited thereto.

The security module 144 may store and process security-required data (for example, data for a mobile payment or data for user authentication).

FIG. 6 illustrates a block diagram of a security module of FIG. 2 or 3 according to an embodiment of the present invention. Referring to FIGS. 2, 3, and 6, the security module 144 may include a processor 144-1 and a security element 144-2. The security module 144 including the processor 144-1 and the security element 144-2 may be formed into one package, and an internal bus connecting the processor 144-1 and the security element 144-2 may be formed in the package.

The security element 144-2 may include a security function to guard against electronic theft of data. Accordingly, the security element 144-2 may include a security region 144-3 for securely storing security data UI. The processor 144-1 may be connected to the AP 141 and transmit or receive signals to or from each other.
