16. A display apparatus having a display module, the display apparatus comprising: a first printed circuit board which is disposed behind the display module, and comprises a plurality of power supply circuit elements; and a second printed circuit board which is disposed to the first printed circuit board; wherein the second printed circuit board comprises: a universal serial bus (USB) port which connects with an external device storing a USB Standard signal; a port which receives a first video signal; a decoder which decodes a second video signal from the USB standard signal and outputs a decoded second video signal; and a signal processing unit which converts at least one of the first video signal and the third video signal into a displayable video signal, wherein a distance between the USB port and the decoder is shorter than a distance between the USB port and the signal processing unit.
When viewed from the back, the first printed circuit board 400 is disposed at the left-rear side of the board supporting frame 240 and the second printed circuit board 300 is disposed at the right-rear side of the board supporting frame 240, in the display apparatus 120 according to an exemplary embodiment of the present invention.
A plurality of power supply circuit elements and an output port 450 may be disposed on the first printed circuit board 400. The plurality of power supply circuit elements supply power to drive the display apparatus 120, and the output port 450 provides power supplied from the power supply circuit elements to the second printed circuit board 300. The output port 450 is connected through a power supply cable to an input port 311.
The first USB port 316 is connected with the computer 110 through a USB cable, and receives a USB standard signal from the computer 110. The first USB port 316 has a difference from the DVI port 314 which is used to receive a video signal from the computer 110, in that the first USB port 316 can receive other signals in addition to the video signal from the computer 110. For example, the first USB port 316 may be used to receive not only a video signal, but also an audio signal, a text signal, a control signal, or others from the computer 110. Although the USB port is capable of two-way communications, the first USB port 316 is classified into an input port in that the USB standard signal transmitted from the computer 110 is transmitted to the display apparatus 120.
The switching unit 342 performs a switch operation according to a `connector priority`. The `connector priority` determines which of a video signal transmitted from the DVI port 314 and a video signal transmitted from the USB port is displayed. That is, if the USB port has the higher priority than the DVI port 314, and if a video is input to both the DVI port 314 and the USB port, the video input to the USB port is displayed first.
Also in the following description, an `interval` between the circuit elements refers to a minimum distance from a predefined point of a circuit element to a predefined point of another circuit element. For example, there may be several distances a, b, c measured from several points of the signal processing unit 344 to several points of the switching unit 342 as illustrated in FIG. 4A. However, the minimum distance from the signal processing unit 344 to the switching unit 342 is distance `a`, according to an exemplary embodiment of the present invention. When the circuit elements are `adjacently disposed`, this means that there is no element between the circuit elements. Therefore, if there is no circuit element mounted on the interval between the circuit elements, it is referred that the elements are adjacently mounted.
Referring to FIG. 4A, input/output ports are disposed at the edge of the four sides of the second printed circuit board 300. The input port 311 to receive power from the first printed circuit board 400 is disposed in the edge area of the second side and adjacent to the first printed circuit board 400. Accordingly, the input port 311 is conveniently connected with the output port 450 mounted on the first printed circuit board 400 through a power cable. The input port 311 may also be mounted at the edge of the third side.
The second circuit module 330 is disposed in the edge area of the third side of the second circuit board 300. That is, the decoder 332, the second memory 334, and the signal converting unit 336 included in the second circuit module 330 are adjacently disposed at the edge of the third side of the second circuit board 300 and above the first USB port 316, so as to be closest to the first printed circuit board 400. The decoder 332, the second memory 334, and the signal converting unit 336 may be disposed from the bottom in a sequential order. Since the area of the decoder 332 on the second printed circuit board 300 is larger than that of the signal converting unit 336, the decoder 332 may be disposed above the signal converting unit 336, and since the second memory 334 provides storage space for operation of the decoder 332, the second memory 334 may be disposed near of the decoder 332.
A distance (d) between the first USB port 316 and the signal converting unit 336 may be shorter than a distance (e) between the first USB port 316 and the signal processing unit 344, and a distance (f) between the first USB port 316 and the decoder 332 may be shorter than the distance (e) between the first USB port 316 and the signal processing unit 344.
FIG. 5 is a view wherein the first printed circuit board 400 and the second circuit board 300 of a display apparatus are engaged on a board supporting frame 240. The first printed circuit board 400 and the second printed circuit board 300 are adjacently mounted on the board supporting frame 240. The output port 450 of the first printed circuit board 400 is connected with the power input port 311 of the second printed circuit board 300 through a power supply cable, and the video output unit of the second printed circuit board 300 is connected with the display module 230 through a video supply cable. Elements illustrated in FIG. 5 are described in FIGS. 2 to 4, and thus a description thereof will be omitted.
