Description

Frame of Plasma Display Panel {FRAME FOR PLASMA DISPLAY PANEL}

The present invention relates to a frame of a plasma display panel, and more particularly, to a frame of a plasma display panel that can be changed in size according to a set case.

Recently, various flat panel displays have been developed to reduce weight and volume, which are disadvantages of cathode ray tubes. Such flat panel displays include Liquid Crystal Display (LCD), Field Emission Display (FED), Plasma Display Panel (PDP), and Electro-Luminescence (EL). And display devices.

Among these, the PDP displays an image using discharge. Such PDPs are used for high resolution televisions, monitors, and indoor / outdoor advertising because they have fast response speed and are suitable for displaying large-area images.

1A and 1B illustrate the internal structure of a conventional plasma display panel.

1A and 1B, a conventional PDP includes a panel 2, a frame (or a heat sink 8) and a printed circuit board 16.

The panel 2 has a front substrate 6 and a back substrate 4. Phosphor not shown is coated on the back substrate 4. The front substrate 6 transmits light generated from the phosphor to display a predetermined image.

The double-sided tape 12 is attached to one end of the panel 2 (back substrate 4 side), and the panel 2 and the frame 8 are bonded to each other by the double-sided tape 12. The frame 8 supports the panel 2 and dissipates heat generated when the panel 2 is driven.

The printed circuit board 16 is attached to the frame 8 to supply a predetermined drive signal to the panel 2. To this end, the printed circuit board 16 and the panel 2 are connected by an FPC (Flexible Printed Circuit) (not shown). Meanwhile, the printed circuit board 16 and the frame 8 are coupled to the plurality of screws 10. For this purpose, the frame 8 has a number of protrusions 14 into which the screws 10 can be inserted.

When the conventional PDP is shipped, the set case 20 shown in FIG. 2 is installed to surround the PDP. The set case 20 includes a filter glass 24 and a back cover 22. The filter glass 24 adjusts the transmittance of light emitted from the panel 2. The back cover 22 protects the PDP from external shock.

Meanwhile, in order to connect the set case 20 and the PDP, the corner 26 portion of the frame 8 protrudes as shown in FIG. 3. A hole 28 is formed in the corner 26, and a screw or the like penetrates the hole 28 to fix the frame 8 to the back cover 22.

In the conventional PDP, the size of the set case 20 is different for each manufacturer (or buyer). If the size of the set case 20 is different, the size of the frame 8 fixed to the set case 20 should also be changed. In other words, when the size of the set case 20 increases, it is difficult to fix the frame 8 to the set case 20.

Accordingly, an object of the present invention is to provide a frame of a plasma display panel that can be changed in size depending on the set case.

1A and 1B show the internal structure of a conventional plasma display panel.

In order to achieve the above object, the frame of the plasma display panel of the present invention supports a panel and heats the panel, and a first fixing part which is formed integrally with the frame and is installed at an edge of the frame, A first fixing part and a second fixing part detachably installed on the frame are provided.

The set case is fixed to the first fixing part when the set case installed to cover the frame and the panel is smaller than the first size, and the second fixing part is installed on the first fixing part when the size of the set case exceeds the first size. The set case is fixed to the second fixing part.

Each edge of the frame includes a first protrusion extending in the vertical direction of the frame such that the frame has a predetermined mechanical strength, and two second protrusions extending from the second fixing part so as to face the first protrusion.

Other objects and features of the present invention in addition to the above objects will become apparent from the description of the embodiments with reference to the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 4 to 5.

4 and 5 are diagrams showing a frame according to an embodiment of the present invention.

4 and 5, the frame 30 according to the embodiment of the present invention includes a fixing part 60 connected to the set case at the corner portion. The fixing part 60 includes a first fixing part 33 formed integrally with the frame 30 and a second fixing part 32 installed in the first fixing part 33.

The first fixing part 33 is provided for each corner portion of the frame 30. The first fixing part 33 is formed to protrude a predetermined portion in the horizontal direction of the frame 30. The second fixing part 32 is fixed to the first fixing part 33 so as to protrude in the horizontal direction of the frame 30 larger than the first fixing part 33.

On the other hand, the edge of the frame 30 is provided with first projections 44 protruding from the frame 30 in the vertical direction so that the frame 30 has a predetermined mechanical strength. The second fixing part 32 is fixed to the first fixing part 33 and the protrusion 44. To this end, the second fixing part 32 includes two second protrusions 43 formed to face the first protrusions 44. The first and second protrusions 44 and 43 are fixed by screws 38 and 39.

That is, the holes 40 and 42 are formed in the first and second protrusions 44 and 43 of the second fixing part 32, and the screws 38 and 39 penetrate the holes 40 and 42 to form the second holes. The fixing part 32 is fixed to the frame 30.

On the other hand, the first fixing part 33 has a circular first hole 51 is formed. In the second fixing part 32, circular second holes 36 and third holes 34 are formed. When the second fixing part 32 is fixed to the first fixing part 33, a screw 45 is installed to penetrate the first hole 51 and the second hole 36.

The frame according to the embodiment of the present invention can set the size of the fixing part 60 to correspond to the size of the set case. In other words, when the size of the set case is small, the first fixing part 33 is fixed to the set case. In addition, when the size of the set case is large, the second fixing portion 32 is installed on the first fixing portion 33, and the second fixing portion 32 is fixed to the set case. Further, by setting the size of the second fixing part 32 to correspond to the size of the set case, the frame 30 can be fixed to the set case regardless of the size of the set case.

As described above, according to the frame of the plasma display panel according to the present invention, the first and second fixing parts may be installed at the corners of the frame to fix the frame to the set case regardless of the size of the set case. In other words, when the size of the set case is small, the second fixing part may be removed, and when the set case size is large, the second fixing part may be installed to fix the frame to the set case regardless of the size of the set case.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
