Abstract

Disclosed herein is a display system incorporating wired and wireless charging apparatuses, including: a switching processing unit supplying and processing a power of a power supply unit according to a mode selected through a switch; a wireless charging unit connected to the switching processing unit and including a pad for wireless charging; a wired charging unit connected to the switching processing unit and a terminal for wired charging; a display unit connected to the switching processing unit; and a control unit connected to the switching processing unit to control operations according to the mode.

Claims

1. A display device incorporating wired and wireless charging apparatuses, comprising:

a switch provided on one surface of a support supporting a display unit and selecting a plurality of operating modes;

a pad for wireless charging connected to the switch to be provided on one portion of a top surface of the support, and transmitting wireless power so as to perform wireless charging of a device for receiving wireless charging according to the operating modes;

a terminal for wired charging connected to the switch and extending from the one portion of the support so as to perform wired charging according to the operating modes;

a light emitting unit connected to the switch and confirming a state of wired charging or wireless charging according to the operating modes; and

a display window connected to the switch to be provided on the one portion of the top surface of the support, and displaying operations of the pad for wireless charging or the terminal for wired charging and functions of the operating modes.

2. The display device as set forth in claim 1, wherein the operating modes include a wireless charging mode using the pad for wireless charging, a wired charging mode through the terminal for wired charging, a display mode using the display unit, and an incorporated mode using both of the wireless charging mode and the wired charging mode.

3. The display device as set forth in claim 1, wherein the pad for wireless charging is included to be adjusted at an angle θ

with respect to one portion of the top surface of the support using a hinge joint or a sliding joint.

4. The display device as set forth in claim 1, wherein the light emitting unit includes a red LED and a green LED provided on the one portion of the support.

5. The display device as set forth in claim 1, wherein the terminal for wired charging has any one of the connection terminal forms of a USB terminal, a serial terminal and a pin terminal according to a connection scheme of a device to be charged.

6. A display system incorporating wired and wireless charging apparatuses, comprising:

a switching processing unit supplying and processing a power of a power supply unit according to a mode selected through a switch;

a wireless charging unit connected to the switching processing unit and including a pad for wireless charging;

a wired charging unit connected to the switching processing unit and a terminal for wired charging;

a display unit connected to the switching processing unit; and

a control unit connected to the switching processing unit to control operations according to the mode.

7. The display system as set forth in claim 6, wherein the switching processing unit includes at least one regulator and at least four terminals to which the switch is selectively connected.

8. The display system as set forth in claim 7, wherein the four terminals include a terminal operated in a wireless charging mode using the wireless charging unit, a terminal operated in a wired charging mode using the wired charging unit, a terminal operated in a display mode in which it blocks a connection to the wireless charging unit and the wired charging unit and executes the display unit, and a terminal operated in an incorporated mode using both of the wireless charging mode and the wired charging mode.

9. The display system as set forth in claim 6, wherein the display unit is a monitor or a digital TV.

10. The display system as set forth in claim 6, wherein the switch is provided on one surface of a support supporting the display unit,
