Abstract

A display apparatus displaying video input through various ports is provided. The display apparatus includes a board which is disposed behind a display module, wherein the board includes a universal serial bus (USB) port which receives a USB standard signal, a decoder which decodes a video signal from the USB standard signal and outputs a decoded signal, a video output unit which outputs a displayable video signal to the display module corresponding to the video signal, wherein the USB port is disposed at an edge of a first side of the board, and the video output unit is disposed at an edge of a second side which is different from the first side of the board. The video output unit receives video from an external apparatus such as a computer through a USB port in addition to a DVI port and D-SUB port, and displays the received video. Display apparatuses having additional ports than the DVI ports and D-SUB ports may be connected to a computer without requiring additional hardware.

Claims

1. A display apparatus comprising:

a printed circuit board which is disposed behind a display module,

wherein the printed circuit board comprises;

a universal serial bus (USB) port which receives a USB standard signal,

a decoder which decodes a video signal from the USB standard signal and outputs a decoded signal,

a signal converting unit which converts the decoded video signal,

a signal processing unit which converts the converted video signal into a displayable video signal, and

a video output unit which outputs to the display module, the displayable video signal corresponding to the video signal,

wherein the USB port is disposed on a first side of the printed circuit board, and the video output unit is disposed on a second side of the printed circuit board which is different from the first side of the printed circuit board.

2. The display apparatus of claim 1, wherein the first side and the second side are opposite to each other.

3. The display apparatus of claim 1,

wherein the decoder, the signal converting unit, and the signal processing unit are adjacently disposed on the printed circuit board.

4. The display apparatus of claim 3, wherein the converted video signal is a Transition Minimized Differential Signaling (TMDS) format signal.

5. The display apparatus of claim 3, wherein the displayable video signal is a low voltage differential signaling (LVDS) format signal.

6. The display apparatus of claim 3, wherein a distance between the USB port and the signal converting unit is shorter than a distance between the USB port and the signal processing unit.

7. A display apparatus comprising:

a board which is disposed behind a display module,

wherein the board comprises;

a universal serial bus (USB) port which receives a USB standard signal,

a decoder which decodes a video signal from the USB standard signal and outputs a decoded signal,

a signal converting unit which converts the decoded video signal,

a signal processing unit which converts the converted video signal into a displayable video signal, and

a video output unit which outputs to the display module, the displayable video signal corresponding to the video signal,

wherein the USB port is disposed on a first side of the board, and the video output unit is disposed on a second side of the board which is different from the first side of the board, and

wherein a distance between the USB port and the decoder is shorter than the distance between the USB port and the signal processing unit.

8. A display apparatus comprising:

a board which is disposed behind a display module, and

a power supply circuit board comprising a plurality of power supply circuit elements,

wherein the power supply circuit board is spaced apart from the board, and is disposed behind the display module, and

wherein the board comprises;

a universal serial bus (USB) port which receives a USB standard signal,

a decoder which decodes a video signal from the USB standard signal and outputs a decoded signal,

a signal converting unit which converts the decoded video signal,

a signal processing unit which converts the converted video signal into a displayable video signal, and

a video output unit which outputs to the display module, the displayable video signal corresponding to the video signal,

wherein the USB port is disposed on a first side of the board, and the video output unit is disposed on a second side of the board which is different from the first side of the board.

9. The display apparatus of claim 8, wherein a power output port mounted in the power supply circuit board is connected with a power input port mounted in the board through a power supply cable.
