The present invention relates to a flat panel display device, and more particularly, to a flat panel display device having an input / output terminal unit for connecting the flat panel display device to an external device on an upper side of a back cover of the flat panel display device.

Unlike general cathode ray tubes, a flat panel display device is a device in which an emission state of each pixel is implemented differently and forms an image as a whole by a driving circuit arranged in a matrix form. Unlike the cathode ray tube, such a flat panel display device has a small volume and thus occupies a small amount of space in a narrow indoor space, thereby increasing consumer preference and increasing its use.

The flat panel display module applied to the flat panel display device includes a liquid crystal display (LCD), a field emission display (FED), and a plasma display panel (PDP) according to a driving method thereof. Etc.

Among them, the plasma display panel (hereinafter referred to as 'PDP') is determined by using red, green, and blue visible light generated by vacuum ultraviolet (VUV) emitted from plasma obtained through gas discharge to excite the phosphor. A display device for implementing the image of the. This PDP can realize a 60-inch or larger screen with a thickness of less than 10 cm. Since it is a self-luminous display device such as a CRT, it has no characteristic of distortion due to color reproduction and viewing angle. And it is attracting attention as a TV and industrial flat panel display having strength in terms of cost.

Such a PDP device is equipped with a PDP in the front and a driving circuit unit in which a signal for driving the PDP is applied to the front, with a chassis made of a material having good thermal conductivity such as aluminum. The front cover is disposed in front of the PDP, and the back cover is disposed behind the driving circuit. The front cover and the back cover are combined to form a PDP device.

In a flat panel display device such as a PDP device configured as described above, an input / output terminal for connecting the flat panel display device to an external device is formed to protrude outward from the rear surface of the flat panel display device.

In this case, the input / output terminal is generally located under the rear surface of the flat display device, and is formed to face the bottom surface when the flat display device is placed on the bottom surface.

This is because when the flat panel display device is placed on the floor, the length of the connection line connected to the input / output terminal can be reduced by forming the input / output terminal near the floor.

In addition, the positioning of the input / output terminals on the lower side of the back cover is related to the cooling of the heat generated in the flat panel display device.

In more detail, when designing a flat panel display device, a cooling fan is installed to cool heat generated inside the flat panel display device. At this time, the cooling fan is generally located above the back cover. In addition, by forming an opening through which the air can pass through the back cover of the flat panel display device, the heated air is allowed to go out through the opening. Therefore, relative to this, the input and output terminal portion is to be provided on the lower side of the back cover.

However, when the input / output terminal of the flat panel display device is placed under the rear side, it is not easy for the user to connect the connection jack of the external device to the input / output terminal of the flat panel display device.

More specifically, flat display devices are generally installed close to the wall, in which case the back of the flat display device is located close to the wall. Accordingly, the input / output terminal formed under the back cover of the flat panel display device is located at a position not visible to the user.

Therefore, even if the user wants to connect the connection jack to the desired input and output terminals, there is a problem in that it is difficult to connect the connection jack and the input and output terminals while looking directly at the position of the input and output terminals.

The present invention has been made to solve the above problems, an object of the present invention is to provide a flat panel display device that is formed with an input and output terminal unit so that the user can easily connect the connection jack to the input and output terminal.

Another object of the present invention is to provide a flat display device configured to allow a user to connect a connection jack while checking a position of an input / output terminal even when the flat display device is located close to a wall.

Still another object of the present invention is to provide a flat display device which is configured to cool the inside of the flat display device even when the input / output terminal part is positioned above the back cover of the flat display device.

Flat display device of the present invention for achieving the above object is a display module; A front cover to protect the front of the display module; A back cover protecting a rear of the display module; And an input / output terminal unit formed on an upper edge portion of the back cover and provided with a plurality of input / output terminals for connection with a single or a plurality of external devices.

According to another aspect of the present invention, a flat panel display device may include a flat panel display module; A front cover protecting the front of the flat panel display module; A back cover protecting a rear of the flat panel display module; An input / output terminal unit formed at an upper side of the back cover; And a cooling fan formed at a side of the input / output terminal unit to cool the inside of the flat panel display device.

With the above structure, even when the flat panel display device is located close to the wall, the user can directly connect when connecting the connection jack of the external device to the input / output terminal part, and the input / output terminal part is formed on the upper side of the back cover. Even in the flat display device there is an advantage that the cooling can be made well.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a rear perspective view of a flat panel display device according to the present invention. FIG. 2 is a diagram illustrating a state in which a terminal part cover protecting an input / output terminal part according to the present invention is removed from FIG.

An input / output terminal unit 10 of the flat panel display device 1 is formed at the center of the upper portion of the back cover 3. The input / output terminal portion 10 is located at the center of the upper portion of the back cover 3 and is formed to face upwards, and a plurality of input / output terminals 14 protruding from the terminal support surface 12. Is formed. The input / output terminal 14 is formed to be connected to a component inside the flat panel display device 1.

The input / output terminal 14 of the input / output terminal unit 10 is formed such that a connection jack of the connection line 50 extended from an external device is connected.

At this time, the input / output terminal part 10 is covered by the terminal part cover 20. The terminal part cover 20 is detachably coupled to the back cover 3. Accordingly, foreign matters such as dust do not flow into the input / output terminal 14 of the input / output terminal unit 10.

In more detail, the terminal part cover 20 includes an upper surface portion 21 positioned horizontally above the input / output terminal portion 10 and a side portion 23 obliquely extending downward from one edge portion of the upper surface portion 21. Is formed.

In the center of the upper surface portion 21, the handle portion 25 is formed to protrude so that the user can easily hold the terminal cover (20).

On the other hand, when the terminal cover 20 covers the input / output terminal part 10 at the center of the lower end of the side part 23, the connection line 50 of the external device connected to the input / output terminal 14 may come out behind the back cover 3. A rectangular connecting line opening 26 is formed so that it can be.

On the other hand, in order to secure the terminal cover 20 to the upper side of the back cover 3, side projections 22 are formed on both side surfaces of the upper surface portion 21, and lower projections 24 on the lower side of the side portion 23. Is formed.

In response to the side protrusions 22 and the lower protrusions 24, the side protrusion coupling grooves 6 and the lower protrusion coupling grooves 8 are formed on the upper side of the back cover 3.

Meanwhile, ventilation holes 4 are formed at both sides of the input / output terminal part 10 in the back cover 3. The vent 4 as described above is also provided in the lower portion of the back cover (3).

Such a vent is intended to allow for good cooling within the flat display device when the input / output terminal portion of the flat display device according to the present invention is formed to be positioned above the back cover.

The position of the vent may be freely formed at any position of the back cover according to the position and type of the cooling fan installed inside the flat panel display device.

In particular, the vent is preferably provided at or near a heat source that generates a lot of heat inside the flat panel display device.

A detailed structure of the location and type of the cooling fan formed inside the flat panel display device according to the present invention will be described in detail below.

Meanwhile, a connection line fixing part 30 to which the connection line 50 is fixed is formed at the center of the back cover 3 so that the connection line 50 of the external device is neatly arranged. The connection line fixing part 30 is preferably formed below the input / output terminal part 10. In a preferred embodiment according to the invention the connection line fixing portion is formed to be provided in the center of the back cover.

The connection line fixing part 30 is connected to the input / output terminal part 10 provided at the upper side of the flat panel display device 1 when the connection line 50 of the external device is positioned behind the back cover 3. It is to make the rear side of the flat display device look neat so that it can be arranged.

As can be seen in FIG. 1, when the input / output terminal portion of the flat display apparatus is formed on the upper side of the back cover of the flat display apparatus according to the present invention, even if the flat display apparatus is installed adjacent to the wall, As it can be seen, when the user connects the connection jack of the external device to the input and output terminals, it can be easily connected.

The flat panel display device is usually formed such that the terminal cover is installed on the back cover to cover the terminal, so that the terminal is not exposed to the outside. This is to prevent foreign substances such as dust from flowing even when the terminal is located on the upper side of the back cover, and also to make the rear side of the flat panel display device look neatly arranged.

The user connects the connection jack to the input / output terminal through the following process. First, the user opens the terminal cover 20 located on the upper side of the back cover 3 (more precisely, the upper edge of the back cover) of the flat panel display device 1, and the input / output terminal to connect the connection jack of the external device ( 14). After connecting the connection jack to the input / output terminal 14 in this manner, the terminal cover 20 is covered. The connection line 50 of the external device is fixed to the connection line fixing part 30 formed at the center of the back cover 3. This completes the connection of the connection line of the external device to the input / output terminals of the flat panel display device.

In this way, the user can simply and conveniently connect the connection line of the external device to the input / output terminal of the flat panel display device.

The configuration of the input / output terminal unit 10 according to the present invention will be described in more detail.

FIG. 3 is a cross-sectional view taken along line II ′ of FIG. 1, and illustrates a state in which the terminal support surface 12 of the input / output terminal part 10 is coupled to the back cover 3.

Referring to FIG. 3, the terminal support surface 12 of the input / output terminal part 10 according to the present invention is coupled to the back cover 3 of the flat panel display device 1 by a fastening member 90 such as a screw.

In more detail, the back cover 3 of the flat panel display device 1 is located at the front part 5 coupled to the front cover 2 and the rear part of the front part 5, and the input / output terminal part 10 is positioned. In addition, the rear projections 6 are formed with a plurality of slit-shaped vents 4.

Referring to FIG. 3, the rear protrusion 6 is formed of a protruding surface positioned at the center of the back cover 3. Therefore, the plane of the rear projection 6 and the plane of the front portion 5 are formed parallel to each other. Between the plane of the rear projection 6 and the plane of the front portion 5, the terminal support surface 12 is formed to be perpendicular to the two planes to face the upper side of the flat display device 1.

In more detail, referring to FIG. 3, the inside of the terminal support surface 12 is coupled to the protrusion 7 extending rearward from one plane of the front part 5 by a fastening member 90 such as a screw. . In addition, the outer side of the terminal support surface 12 is coupled by a fastening member 90 such as a screw to the protrusion 8 extending forward from the top of the plane of the rear protrusion 6.

A plurality of holes are formed on the terminal support surface 12 coupled to the back cover 3 as described above, and a plurality of input / output terminals 14 are formed to protrude from the holes. The input / output terminal 14 is formed to be connected to a component located inside the flat panel display device 1, for example, a VSC board for processing a video signal.

According to a preferred embodiment of the present invention, the terminal support surface of the flat panel display device is formed to face the upper side of the flat panel display device as described above. At this time, it may be possible to form the terminal support surface in parallel or obliquely with the back cover to face the rear side of the flat panel display device. When the terminal support surface is formed to face the rear side as described above, since the input / output terminals face the rear side rather than the upper side, the terminal cover may be unnecessary to prevent foreign substances such as dust from entering the input / output terminals. .

4 is a plan view of the connecting line fixing part 30 formed at the center portion of the back cover 3.

Referring to FIG. 4, the connection line fixing part 30 is formed perpendicular to the back cover 3 and has a vertical portion 32 having a predetermined height, and the back cover 3 from one end of the vertical portion 32. And a horizontal portion 34 extending laterally horizontally and a ring portion 36 bent toward the back cover 3 at one end of the horizontal portion 34. The end of the ring portion 36 is spaced apart from the back cover 3 by a predetermined interval, and forms an opening 38 so that the connecting line 50 of the external device can enter the inside of the connecting line fixing part 30. . At this time, the inside of the connection line fixing portion 30 is preferably formed in a space wider than the thickness of the predetermined connection line 50 so that a plurality of connection lines 50 can be located.

Since the connection line fixing part is a component for allowing the connection line to be neatly arranged without being scattered, even if it is different from the shape of the present embodiment, it is natural that any structure can be adopted as long as the connection line can be arranged together.

Meanwhile, according to another aspect of the present invention, as described above, the configuration of forming the input / output terminal portion on the upper side of the back cover of the flat panel display device is preferably considered together with the cooling structure formed inside the flat panel display device.

This is because, unlike the configuration in which the ventilation holes are provided in the upper portion of the conventional flat display apparatus, the back cover of the flat display apparatus according to the present invention is blocked by the input / output terminal portion.

Hereinafter, in consideration of such a point, a flat display device according to another aspect of the present invention will be described.

At this time, in the flat display device according to another aspect of the present invention described below, the structure of the input / output terminal portion, the terminal cover and the connecting line fixing portion formed on the back cover of the flat display device is the same as the configuration described above.

Therefore, description of overlapping contents will be omitted and the flat display device according to another aspect of the present invention will be described based on the internal structure of the flat display device.

According to another aspect of the present invention, a flat panel display device may include a flat panel display module; A front cover protecting the front of the flat panel display module; A back cover protecting a rear of the flat panel display module; An input / output terminal unit formed at an upper side of the back cover; Cooling fans formed on both sides of the input and output terminal portion is included.

First, the internal structure of the flat panel display device having such a configuration will be described.

Looking at the structure of the PDP device consisting of a plasma display panel as an example of a flat panel display device according to the present invention, the PDP device is a PDP is installed in the front center around the chassis made of a good thermal conductivity material such as aluminum, At the rear, a driving circuit portion to which a signal for driving the PDP is applied is mounted. In addition, the front cover is disposed in front of the PDP, and the back cover is disposed behind the driving circuit unit. The front cover and the back cover are combined to form a PDP device.

FIG. 5 schematically illustrates a driving circuit unit 100 of a PDP device as one embodiment of such a flat panel display device.

Looking at the configuration of the driving circuit unit 100 with reference to Figure 5, the driving circuit unit 100 is an X board 110 for receiving information on a plurality of address electrodes, and a Y board for receiving information for a plurality of scan electrodes 120, a Z board 130 for receiving information on a plurality of common sustain electrodes, a VSC board 140 for processing video signals, a power board 150 for controlling power, and a volume of sound The control keyboard 160, a speaker 170 for inputting an external control signal, an input / output terminal 10 related to a video signal for controlling various inputs and outputs of a video signal, and a power switch 180 for controlling power externally. And an EMI filter 190 for reducing EMI flowing through a power line for connecting the power switch 180 and an internal circuit.

At this time, the X board 110, the Y board 120 and the Z board 130 are located in the vertical direction to each other, the control keyboard 160, the speaker 170, the power switch 180 and the EMI filter ( 190 are formed to overlap each other. In addition, the input / output terminal part 10 according to the present invention is located above the back cover 3.

The flat panel display device according to another aspect of the present invention is characterized in that the cooling fan and the ventilation holes are installed inside the flat panel display device to cool the driving circuit unit 100 shown in FIG.

At this time, in the flat panel display device according to the second embodiment of the present invention, cooling fans are positioned on both side surfaces of the input / output terminal unit 10.

At this time, the cooling fan is formed of an axial fan (60). Such an axial flow fan 60 may use an axial flow fan generally used in the prior art.

FIG. 6 illustrates a cooling fan installed as described above and a flow of air flowing inside the flat panel display device when the cooling fan is operated. In this case, in order to facilitate understanding of the drawings, the driving circuit unit 100 illustrated in FIG. 5 is omitted in FIG. 6.

Referring to Figure 6, the lower side and both side portions of the back cover to form a vent so that the air flows from the outside when the axial fan is operating.

As such, since the cooling fan is located at both sides of the input / output terminal part, the input / output terminal part is positioned in the cooling area most affected by the cooling fan. Therefore, the increase in the temperature near the input / output terminal portion can be suppressed as much as the vent hole is not formed where the input / output terminal portion is located.

7 shows a third embodiment of a flat panel display device according to another aspect of the present invention.

The third embodiment of the present invention is the same as the second embodiment in other parts, and the axial flow fan installed in the second embodiment is characterized in that the cross flow fan 70 is replaced.

At this time, it is preferable that an opening is formed in the upper portion of the cross flow fan 70 so that air passing through the cross flow fan can escape to the outside. FIG. 7 illustrates a cross flow fan installed as described above and a flow of air flowing inside the flat panel display apparatus when the cross flow fan operates.

As described above, when the input / output terminal unit 10 is formed on the back cover of the flat panel display device and the crossflow fans 70 are formed on both side surfaces of the input / output terminal unit 10, as compared with the flat display device according to the second embodiment, When cooling inside the flat panel display device, there is a difference in the air flow direction.

That is, when the cross flow fan 70 is installed on both side surfaces of the input / output terminal unit 10 as described above, when the cross flow fan 70 is operated, the air inside the flat panel display device is lower than the back cover as shown in FIG. 6. Flows upward from the side and exits above the cross flow fan 70.

Thus, the installation of the crossflow fan 70 on both sides of the input / output terminal unit 10 may have a better effect as the screen of the flat panel display device 1 becomes larger.

This is because the larger the screen of the flat display device 1 can be, the longer the length of the crossflow fan that can be installed on the upper side of the back cover, so that the inside of the flat display device 1 can be better cooled.

8 illustrates a fourth embodiment of a flat panel display device according to another aspect of the present invention.

The fourth embodiment of the present invention is the same as that of the third embodiment in the other parts, and in the third embodiment, the crossflow fan 70 provided on both sides of the input / output terminal part is arranged along both side edges of the flat panel display device. The vertical position is characteristically different.

At this time, it is preferable that openings are formed at both outer sides of the crossflow fan 70 so that air passing through the crossflow fan 70 can escape to the outside.

FIG. 8 illustrates a cross flow fan installed as described above and a flow of air flowing inside the flat panel display apparatus when the cross flow fan operates.

Thus, forming the cross flow fan 70 on both side edges of the flat panel display device is compared to the flat panel display device according to the second embodiment, in the direction of air flow during cooling inside the flat panel display device 1. There will be a difference.

That is, when the cross flow fan 70 is installed at both side edges of the flat display device 1 as described above, the air inside the flat display device during operation of the cross flow fan, as shown in FIG. It enters the inside of the flat panel display device 1 from the lower side and exits to the side of the cross flow fan 70.

Thus, the installation of the crossflow fans at both side edges of the flat panel display device 1 having the input / output terminal unit 10 positioned on the upper side of the back cover has a better effect as the screen of the flat panel display device 1 becomes smaller. I can make it.

This is because when the screen of the flat panel display device 1 becomes small, the length of the crossflow fan that can be installed on the upper side of the back cover is also shortened so that the cooling efficiency decreases. Therefore, the crossflow fan is not installed horizontally on the upper side of the back cover. This is because the air can be cooled by using a longer crossflow fan by forming the display device 1 perpendicular to both edge portions.

9 shows a fifth embodiment of a flat panel display device according to another aspect of the present invention.

The fifth embodiment of the present invention is the same as that of the third embodiment in the other parts, and in the third embodiment, the horizontal flow fan 70 provided on both sides of the input / output terminal part 10 includes the flat display device 1. It is characteristically positioned horizontally along the lower edge of the.

Thus, when the cross flow fan 70 is formed in the lower edge portion, it is preferable that the ventilation holes are formed on both sides of the input / output terminal portion and the side edge portions.

In addition, it is preferable that an opening is formed in the lower portion of the cross flow fan 70 so that air passing through the cross flow fan can escape to the outside.

FIG. 9 illustrates a cross flow fan installed as described above and a flow of air flowing inside the flat panel display device when the cross flow fan operates.

As described above, the forming of the cross flow fan 70 at the lower edge portion of the flat display apparatus 1 according to the present invention is compared with the flat display apparatus according to the third embodiment, when cooling the air inside the flat display apparatus. There is a difference in the flow direction of.

That is, when the cross flow fan () is installed at the lower edge portion of the flat display apparatus 1 as described above, the air inside the flat display apparatus when the cross flow fan 70 is operated, as shown in FIG. It is forced to flow from the upper side of the cover to the lower side of the flat panel display device to exit the lower side of the cross flow fan.

Thus, installing the cross flow fan 70 on both sides of the input / output terminal unit 10 may have a better effect as the screen of the flat panel display device becomes smaller.

This is because when the screen of the flat panel display device becomes smaller, the length of the crossflow fan that can be installed on the upper side of the back cover is also shortened, thereby reducing the cooling efficiency.

In order to improve the cooling efficiency, the horizontal flow fan is not provided horizontally on the upper side of the back cover, but is horizontally formed at the lower edge portion of the flat panel display device, so that the air can be cooled using a longer horizontal flow fan.

Various embodiments of the flat panel display device according to another aspect of the present invention described above provides cooling inside the flat panel display device, which may be caused by not forming a vent on the upper portion of the back cover as the input / output terminal is located above the back cover. To achieve more effectively.

As described above, in the state where the input / output terminal unit is positioned above the flat display device according to the present invention, as described above, the inside of the flat display device is cooled, so that a vent hole is not formed at the top of the flat display device. In other words, the inside of the flat panel display device can be cooled well.

The embodiments described above are intended to describe one embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments and may be appropriately modified within the scope of the claims. For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.

The flat panel display device according to the present invention has an effect that can be easily connected when a user connects a connection jack to an input / output terminal.

In addition, the flat panel display device according to the present invention has the effect that the user can connect the connection jack while looking at the input and output terminals even when located near the wall.

In addition, the flat display device according to the present invention has an effect that the flat display device can be cooled more efficiently even when an input / output terminal is formed on the back cover.
