Position control device of plasma display panel {APPARATUS FOR CONTROLLING POSITION IN PLASMA DISPLAY PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position adjusting device of a plasma display panel (PDP), and more particularly, to an apparatus for adjusting a vertical movement and a tilting position of a PDP.

Usually, a PDP is a panel comprised by the transparent electrode arrange | positioned in the horizontal direction and the vertical direction on the inner surface of glass by enclosing the gas of neon lamp in the narrow gap between two thin glass substrates. That is, the horizontal electrode and the vertical electrode can be charged individually, and the pixel at the point where the pair of charged electrodes meet will emit light by gas ionization.

As such, the PDP-TV was developed using a phenomenon of emitting light by gas ionization. The PDP-TV is a conventional display device that scans an electron beam with an existing electron gun to form an image on a screen of a cathode ray tube. As a next-generation display device, a character or an image can be displayed clearly by using light emission of a liquid crystal device by discharge, and the thickness thereof is formed very thin so that it can be fixed to a wall or viewed in a stand type.

Here, the PDP TV fixed to the wall means having a form in which a supporting means such as a projection type having strength enough to support its own weight is attached to the wall, and the PDP TV is hung on the supporting means. Means that the PDP TV is mounted on a stand having a width enough to vertically support the PDP TV. At this time, the wall-mounted type is mainly used in places (banquet halls, exhibition halls, etc.) that are not ordinary homes, and the stand type is mainly used in general homes where the space is not relatively large.

On the other hand, in the wall-mounted PDP TV, if the height is to be adjusted as necessary, the height is removed by removing the support means attached to the wall and then attaching the support means again to the wall position of the desired height. In this case, there is a problem that the height adjustment is not only very cumbersome but also takes a lot of time, and this problem is finally expressed as a dissatisfaction with the service needs of consumers.

In addition, in the stand-type PDP TV, if the height is to be adjusted as needed, the height can be adjusted by supporting a separate pedestal having a certain height under the stand, in which case the user convenience There is a problem falling. In other words, sitting on a sofa or watching television, or lying on the floor of the living room can watch television, considering the increase in eye fatigue due to audio-visual, it is necessary to watch the television with an appropriate audio-visual, so to sit on the sofa to watch television It is required to adjust the height of the PDP TV at the time and the height of the PDP TV when watching the television lying on the floor.

However, in the conventional method, it is very cumbersome from the user's point of view because the base must be supported or removed from the bottom of the PDP TV every time the viewing posture and the position are changed. It is acting as a factor to lower the.

Accordingly, the present invention has been made to solve the above problems, the purpose of which is to use the electromotive force characteristic selectively generated according to the intrinsic polarity of the PDP to freely adjust the position and tilt of the PDP position In providing a position adjusting device of.

In the present invention for achieving the above object is a position adjusting device of the PDP means for generating a control signal for adjusting the position of the PDP in response to the user operation signal, and fixing and fixing the position of each step in response to the user operation signal And means for releasing, switching means for selectively performing switching operations in accordance with a control signal, and adjusting means for selectively generating electromotive force in accordance with the switching operation to adjust the position of the PDP by the same polarity. .

On the other hand, the circular support 410 is connected to the PDP (S6), the positive polarity of each of the electromagnets (S1, S2, S3, S4) is connected to the first, second, third, fourth switching unit (210, 220, 230, 240), respectively (-) Polarity has a structure that can push out the same polarity (-) as each electromagnet (SS1, SS2, SS3, SS4) ((-) polarity) in the fixed support 420, and also the fixed support The positive polarity of the respective electromagnets SS1, SS2, SS3, and SS4 is connected to the fifth, sixth, seventh, and eighth switching parts 310, 320, 330, and 340, respectively, and the negative polarity of the negative electrode is the circular support 410. Each of the electromagnets S1, S2, S3, and S4 has a structure capable of being pushed out with the same polarity (-) as the (-) polarity.

Then, the electromagnets S1 and S2 by the switching operation of the circular support switching means 200 and the fixed support switching means 300 according to the control of the microcomputer 100 for vertical movement and angle adjustment of the PDP according to the present invention. (S3, S4, SS1, SS2, SS3, SS4) will be described for the process of selectively operating to generate an electromotive force.

First, the vertical movement control of the PDP will be described.

That is, when the microcomputer 100 turns on both the circular support switching means 200 and the fixed support switching means 300 by simultaneously generating a turn-on signal through U1 to U8 (the output port of the microcomputer 100), the electromagnet ( Since S1, S2, S3, S4, SS1, SS2, SS3, and SS4 are all turned on to generate electromotive force, the negative polarity of the circular support 410 and the negative polarity of the fixed support 420 are the same.

In more detail, when an operation signal in which the user's desired position moves vertically upward is provided by the user, if the desired position is a one-step position, the microcomputer 100 has a circular support 410 according to the turn-on signal. Vertically moving upwards to the position of the step to control to be fixed to the first-stage position fixing means (S5-1), and if the desired position is the second-stage position, the microcomputer 100 is a circular support 410 in accordance with the turn-on signal 2 Vertically moved upward to the position of the step is controlled to be fixed to the two-stage position fixing means (S5-2), and finally, if the desired position is the highest point position, the microcomputer 100 is a circular support 410 according to the turn-on signal Vertically moving upward to the position of the highest stage is controlled to be fixed to the highest stage position fixing means (S5-3).

In addition, when an operation signal in which the user's desired position moves vertically downward is provided by the user, if the desired position is a two-stage position, the microcomputer 100 is fixed by controlling the peak stage position fixing means S5-3. After the release, the circular support 410 is moved vertically downward from the highest stage to the two-stage position in accordance with the turn-off signal to be fixed to the two-stage position fixing means S5-2, and then the desired position is the one-stage position. The back side, the microcomputer 100 controls the two-stage position fixing means (S5-2) to release the fixed, and then the circular support 410 is moved vertically downward from the two-stage position to the one-stage position according to the turn off signal 1 Control to be fixed to the step position fixing means (S5-1).

Next, the angle adjustment of the PDP will be described.

That is, when the PDP is controlled at an upward angle, the microcomputer 100 simultaneously generates turn-on signals through only U3 and U4 and U5 and U6 so that the third and fourth switching units 230 and 240 and the fifth and six switching units ( When turning on 310 and 320, the electromagnets S3, S4, SS1 and SS2 are turned on to generate electromotive force so that the circular support 410 rotates at an upward angle. In this case, the control is performed so as to be fixed to the position fixing means S5-1, 2, and 3, respectively.

On the contrary, when the PDP is controlled at a downward angle, the microcomputer 100 simultaneously generates turn-on signals through only the U1 and U2 and the U7 and U8 so that the first and second switching units 210 and 220 and the seventh and eighth switching units ( When the 330 and 340 are turned on, the electromagnets S1, S2, SS3, and SS4 are turned on to generate electromotive force, thereby rotating the circular support 410 at a downward angle. In this case, the control is performed so as to be fixed to the position fixing means S5-1, 2, and 3, respectively.

Here, the step-by-step position fixing means (S5-1, 2, 3) is a locking member (not shown) located on the support means 400 side and a fixing groove (not shown) located on the circular support 410 side. To be secured via In addition, the position fixing means (S5-1, 2, 3) has been described as being adjustable in three steps, but this is only illustrated for the convenience of explanation and enhancement of understanding, the present invention is not necessarily limited thereto. Therefore, if more precise control, it can be installed in more than three stages.

With reference to the flowchart of FIG. 2, the operation of the position adjusting device of the PDP according to the present invention will be described in more detail based on the above-described configuration.

First, while the PDP TV is in the standby mode or the viewing mode, the microcomputer 100 inputs an operation signal for adjusting the vertical up / down height of the PDP S6 from an input means (not shown), or up / down It is determined whether or not an operation signal for adjusting the downward angle is input (step 201).

When an operation signal for vertical vertical height adjustment of the PDP S6 is input in the determination step 201, it is checked whether the input operation signal is a vertical upward operation signal or a vertical downward operation signal (step 202). ).

In the case of the vertical up-operation signal in the check step 202, if the desired position is the first step position, the microcomputer 100 simultaneously generates a turn-on signal through the U1 to U8, so that the circular support switching means 200 and the fixed support switching means ( When all of the 300 is turned on, the electromagnets S1, S2, S3, S4, SS1, SS2, SS3, SS4 are all turned on to generate an electromotive force, so that the negative polarity and the fixed support 420 of the circular support 410 are generated. (-) Polarity of the to push each other with the same polarity so that the circular support 410 is moved vertically upward to the position of the first stage to control the first stage position fixing means (S5-1) to the locking member and the fixing groove for fixing To be fixed.

Subsequently, if the desired position is a two-stage position, the microcomputer 100 releases the fixing control of the one-stage position fixing means S5-1, and then the circular support 410 is vertically raised to the two-stage position according to the turn-on signal. By moving to control the two-stage position fixing means (S5-2) to be fixed by the locking member and the fixing groove for fixing.

Finally, if the desired position is the highest point position, the microcomputer 100 releases the fixed control of the two-stage position fixing means (S5-2), and then the circular support 410 is vertical to the position of the highest point in accordance with the turn-on signal. It moves upward to control the highest step position fixing means S5-3 so as to be fixed by the locking member and the fixing groove (step 203).

In the case of the vertical down operation signal in the check step 202, the microcomputer 100 generates turn-off signals simultaneously through U1 to U8 to turn off both the circular support switching means 200 and the fixed support switching means 300. In this case, the electromagnets S1, S2, S3, S4, SS1, SS2, SS3, and SS4 are all turned off so that no electromotive force is generated, so that the negative polarity of the circular support 410 and the negative polarity of the fixed support 420 are eliminated. If the desired position is moved from the highest stage to the second stage position by stopping the pushing operation with each other with the same polarity, the microcomputer 100 controls the highest stage position fixing means S5-3 to release the fixed one, and then turns According to the off signal, the circular support 410 moves vertically downward from the highest stage to the two-stage position to control the two-stage position fixing means S5-2 to be fixed by the locking member and the fixing groove.

Subsequently, if the desired position is moved to the one-stage position, the microcomputer 100 controls the two-stage position fixing means S5-2 to release the fixed one, and then the circular support 410 is in the two-stage position according to the turn-off signal. In order to control the first stage position fixing means (S5-1) by moving vertically downward to the first stage position to be fixed by the locking member and the fixing groove for fixing (step 204).

When an operation signal for adjusting the up / down angle of the PDP S6 is input in the determination step 201, it is checked whether the input operation signal is an up angle operation signal or a down angle operation signal (step 205). .

In the check step 205, the microcomputer 100 generates turn-on signals simultaneously through only U3 and U4 and U5 and U6, so that the third and fourth switching units 230 and 240 and the fifth and sixth switching are performed. When the parts 310 and 320 are turned on, the electromagnets S3, S4, SS1, and SS2 are turned on to generate electromotive force, thereby rotating the circular support 410 at an upward angle. At this time as well, each step position fixing means S5-1, 2, 3 is controlled to be fixed by the locking member and the fixing groove (step 206).

In the check step 205, the microcomputer 100 simultaneously generates turn-on signals through only U1 and U2 and U7 and U8 to switch the first and second switching units 210 and 220 and the seventh and eighth switches. When the parts 330 and 340 are turned on, the electromagnets S1, S2, SS3, and SS4 are turned on to generate electromotive force, thereby rotating the circular support 410 at a downward angle. At this time as well, each step position fixing means S5-1, 2, 3 is controlled to be fixed by the locking member and the fixing groove (step 207).

Meanwhile, when an operation signal for adjusting the right / left angle of the PDP S6 is provided in the determination step 201 according to another embodiment of the present invention, whether the input operation signal is a right angle operation signal or a left direction angle. It is checked whether it is an operation signal (step 208).

In the check step 208, the microcomputer 100 generates a turn-on signal at the same time through only the U1 and U3 and U6 and U8 to switch the first and third switches 210 and 230 and the sixth and eighth switches. When the parts 320 and 340 are turned on, the electromagnets S1, S3, SS2, and SS4 are turned on to generate electromotive force, so that the circular support 410 rotates at a rightward angle. At this time as well, each step position fixing means S5-1, 2, 3 are controlled to be fixed by the locking member and the fixing groove (step 209).

In the check step 208, when the left angle manipulation signal is generated, the microcomputer 100 simultaneously generates turn-on signals through only U2 and U4 and U5 and U7 to switch the second and fourth switches 220 and 240 and the fifth and seven switching. When the parts 310 and 330 are turned on, the electromagnets S2, S4, SS1, and SS3 are turned on to generate electromotive force, thereby rotating the circular support 410 at a leftward angle. At this time, each step position fixing means (S5-1, 2, 3) is controlled to be fixed by the locking member and the fixing groove (step 210).

Accordingly, the PDP position adjusting apparatus of the present invention uses the polarity formed on one side of the circular support 410 in the support means 400 for supporting the PDP (S6) and the electromotive force of the polarity formed on one side of the fixed support 420. You can easily adjust the vertical up / down, up / down angle, and left / right angle of the PDP.

As described above, the present invention is to adjust the height in such a way to change the position of the support means for holding the wall-mounted PDP TV on the wall or to install a separate pedestal under the stand-type PDP TV Unlike the above-described conventional method of adjusting the height, the vertical movement of the PDP up and down, and the up and down of the PDP by freely adjusting the position of the PDP by using the electromotive force characteristic selectively generated according to the intrinsic polarity of the electromagnet, thereby adjusting the height.
