It relates to a device that can be fixed by adjusting.

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 support means attached to the wall is removed, and then the support means is reattached to the wall position of the desired height to hang the PDP TV. In this case, the height adjustment work is not only very cumbersome but also takes a lot of time, and this problem is finally expressed as a dissatisfaction with 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 and the illumination sensor selectively generated according to the intrinsic polarity of the PDP according to the up and down operation and the position of the slope The present invention provides a position control device using a PDP illuminance sensor that can measure and fix illuminance to an optimal illuminance position.

That is, a plurality of electromagnets are arranged at regular intervals on one side of the circular support, and a plurality of electromagnets are arranged at regular intervals on one side of the fixed support, and then the polarity (-polarity) of the circular support and the polarity (-polarity) of the fixed support are In the same way, the height and angle of the PDP are automatically fine-tuned using the pushing force of the same polarity of electromagnet.

At this time, the microcomputer 100 attaches an illuminance sensor 500 to the PDP (S6) side, and measures the illuminance according to the position of the up and down motion and the tilt of the position of the PDP (S6) to which the illuminance sensor 500 is attached. By adjusting and fixing the PDP (S6) to the position of the illuminance, i.e., the lowest illuminance, the objectives of the present invention can be easily achieved through such technical means.

Here, each of the switching units 210, 220, 230, 240, 310, 320, 330, 340, one transistor, that is, the first switching unit 210 is composed of a transistor (Q1), the second switching unit 220 ) Is composed of a transistor Q2, the third switching unit 230 is composed of a transistor Q3, the fourth switching unit 240 is composed of a transistor Q4, the fifth switching unit 310 is The sixth switching unit 320 includes the transistor Q6, the seventh switching unit 330 includes the transistor Q7, and the eighth switching unit 340 includes the transistor Q5. Q8).

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. Here, the polar structure of the electromagnets S1, S2, S3, S4, SS1, SS2, SS3, SS4 may be changed.

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) selectively operate to generate electromotive force, and use the illuminance sensor to measure the illuminance according to the up and down motion and the position of inclination by using the illuminance sensor Explain the process of adjustment.

In the state where the illuminance sensor 500 is mounted at a specific position of the PDP S6, the microcomputer 100 receives the illuminance measured through the mounted illuminance sensor 500 and adjusts the optimal illuminance to the measured position. .

First, the microcomputer 100 measures illuminance measured differently according to a position change of the PDP S6, that is, a vertical motion and a tilt position.

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. The PDP S6 is vertically moved by pushing each other out.

At this time, the microcomputer 100 receives the illuminance of measuring whether the PDP S6 moves vertically and at the same time the light of the reference value or more is input through the illuminance sensor 500.

 On the contrary, when the microcomputer 100 turns off the circular support switching means 200 and the fixed support switching means 300 by simultaneously generating a turn-off signal through U1 to U8, the electromagnets S1, S2, S3, and S4. Since the SS1, SS2, SS3, and SS4 are all turned off and no electromotive force is generated, the negative polarity of the circular support 410 and the negative polarity of the fixed support 420 stop pushing each other with the same polarity. The PDP S6 moves vertically down.

At this time, the microcomputer 100 receives the illuminance measured by the illuminance sensor 500 while the PDP S6 moves vertically.

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 moved to the position of the step is controlled to be fixed to the first stage position fixing means (S5-1) and at the same time receives the illuminance measured by the illumination sensor 500.

Subsequently, when the desired position is a two-stage position, the microcomputer 100 controls the circular support 410 to be vertically moved upward to the two-stage position according to the turn-on signal to be fixed to the two-stage position fixing means S5-2. At the same time, the illuminance measured by the illuminance sensor 500 is provided.

And at the same time receives the illuminance measured by the illuminance sensor 500.

Next, when an operation signal for moving the position desired by the user vertically downward is provided by the user, if the desired position is a two-stage position, the microcomputer 100 controls and fixes the peak stage position fixing means S5-3. After the release, the circular support 410 moves vertically downward from the highest stage to the two-stage position according to the turn-off signal and is controlled to be fixed to the two-stage position fixing means S5-2. The measured illuminance is provided.

Subsequently, if the desired position is a one-step 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. It is controlled to be fixed to the first stage position fixing means (S5-1) by moving vertically downward to the first stage position and at the same time receives the illuminance measured by the illuminance sensor 500.

Next, the microcomputer 100 measures the illuminance measured differently according to the up / down angle adjustment of the PDP S6 through the illuminance sensor 500.

That is, when controlling the PDP (S6) 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 sixth ones are turned on. When the switching unit 310, 320 is turned on, the electromagnets (S3, S4, SS1, SS2) is turned on to generate an electromotive force to rotate the circular support 410 at an upward angle and at the same time the illuminance measured by the illumination sensor 500 Are provided. 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 S6 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 signals are controlled. When the switching units 330 and 340 are turned on, the electromagnets S1, S2, SS3, and SS4 are turned on to generate electromotive force so that the circular support 410 rotates at a downward angle and the illuminance measured by the illuminance sensor 500 is simultaneously measured. Are provided. In this case, the control is performed so as to be fixed to the position fixing means S5-1, 2, and 3, respectively.

Next, the microcomputer 100 measures the illuminance measured differently according to the right / left angle adjustment of the PDP S6 through the illuminance sensor 500.

That is, when the PDP S6 is controlled at the right angle, the microcomputer 100 simultaneously generates turn-on signals through only the U1 and U3 and the U6 and U8, so that the first and third switching units 210 and 230 and the sixth and eighth signals are turned on. When the switching unit (320, 340) is turned on, the electromagnets (S1, S3, SS2, SS4) is turned on to generate an electromotive force to rotate the circular support 410 at the right angle and at the same time the illuminance measured by the illumination sensor 500 Are provided. 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 for fixing.

On the contrary, when the PDP S6 is the left angle manipulation signal, the microcomputer 100 simultaneously generates turn-on signals through only U2 and U4 and U5 and U7 to switch between the second and fourth switching units 220 and 240 and the fifth and seventh 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 providing the illuminance measured by the illuminance sensor 500 while rotating the circular support 410 at a leftward angle. Receive. 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 for fixing.

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.

As described above, the microcomputer 100 compares the illuminance measured through the illuminance sensor 500 according to the vertical up / down movement adjustment, the up / down angle adjustment, and the right / left angle adjustment, respectively. Adjust the PDP (S6) to the position at the low illuminance to be fixed.

If the desired position is moved from the highest stage to the second stage (step 221), the microcomputer 100 controls the highest stage position fixing means (S5-3) to release the fixed position and then turns According to the off signal, the circular support 410 moves vertically downward from the highest stage to the second stage position (step 223) to control the second stage position fixing means S5-2 to be fixed by the locking member and the fixing groove. At the same time, measured by the light sensor 500 It receives a light intensity (step 225).
