Hereinafter, a stereoscopic plasma display device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for schematically explaining the configuration of a three-dimensional plasma display device according to the present invention.

Referring to FIG. 1, a stereoscopic plasma display apparatus may include a plasma display panel 100 and a stereoscopic glasses 300.

The plasma display panel 100 includes a left sub-frame including at least one sub-field and a right sub-frame including at least one sub-field. An image may be embodied in a frame.

The stereoscopic glasses 300 may include a left eye lens 301 and a right eye lens 302. The left eye lens 301 is turned on when an image according to the left eye subframe is implemented on the screen of the plasma display panel 100, and the right eye lens 302 is displayed as a plasma display on the right eye subframe. When implemented on the screen of the panel 100 may be turned on.

Accordingly, the viewer wearing the stereoscopic glasses 300 recognizes the image according to the left eye subframe by the left eye and the image according to the right eye subframe by the right eye, thereby implementing the stereoscopic image on the screen of the plasma display panel 100. It is possible to obtain a visual effect.

Operation of the stereoscopic glasses 300 will be described in more detail below.

As shown in FIG. 1, the plasma display panel 100 includes a rear substrate 211 having a plurality of second electrodes 213 and X intersecting with the plurality of first electrodes 202 (Y) and 203 (Z). It may include.

Here, the first electrodes 202 and 203 may include scan electrodes 202 and Y parallel to each other, and sustain electrodes 203 and Z, and the second electrode 211 may be referred to as an address electrode.

On the front substrate 201 where the scan electrodes 202 and Y and the sustain electrodes 203 and Z are formed, the discharge currents of the scan electrodes 202 and Y and the sustain electrodes 203 and Z are limited and the scan electrodes 202 and Y are restricted. ) And an upper dielectric layer 204 may be arranged to insulate between the sustain electrodes 203 and Z.

A protective layer 205 may be formed on the front substrate 201 where the upper dielectric layer 204 is formed to facilitate discharge conditions. The protective layer 205 may include a material having a high secondary electron emission coefficient, such as magnesium oxide (MgO) material.

The address electrodes 213 and X are formed on the rear substrate 211, and the address electrodes 213 and X are covered on the upper side of the rear substrate 211 on which the address electrodes 213 and X are formed. A lower dielectric layer 215 may be formed that insulates X).

On top of the lower dielectric layer 215, a partition space 212, such as a stripe type, a well type, a delta type, a honeycomb type, etc., is formed on the discharge space, that is, to partition the discharge cells. Can be. Accordingly, the first discharge cell emitting red (R) light, the second discharge cell emitting blue (B) light, and the green (Green) light between the front substrate 201 and the rear substrate 211. : G) A third discharge cell or the like that emits light can be formed.

The partition 212 may include a first partition 212b and a second partition 212a, and a height of the first partition 212b and a height of the second partition 212a may be different from each other.

In the discharge cell, the address electrode 213 may cross the scan electrode 202 and the sustain electrode 203. That is, the discharge cell is formed at the point where the address electrode 213 crosses the scan electrode 202 and the sustain electrode 203.

A predetermined discharge gas may be filled in the discharge cell partitioned by the partition wall 212.

In addition, a phosphor layer 214 that emits visible light for image display may be formed in the discharge cells partitioned by the partition wall 212. For example, a first phosphor layer that generates red light, a second phosphor layer that generates blue light, and a third phosphor layer that generates green light may be formed.

In addition, the address electrode 213 formed on the rear substrate 211 may have substantially the same width or thickness, but the width or thickness inside the discharge cell may be different from the width or thickness outside the discharge cell. . For example, the width or thickness inside the discharge cell may be wider or thicker than that outside the discharge cell.

When a predetermined signal is supplied to at least one of the scan electrode 202, the sustain electrode 203, and the address electrode 213, discharge may occur in the discharge cell. As such, when discharge is generated in the discharge cell, ultraviolet rays may be generated by the discharge gas filled in the discharge cell, and the ultraviolet rays may be irradiated onto the phosphor particles of the phosphor layer 214. Then, a predetermined image may be displayed on the screen of the plasma display panel 100 by the phosphor particles irradiated with ultraviolet rays to emit visible light.

FIG. 2 is a diagram for explaining a frame for implementing a stereoscopic image.

Referring to FIG. 2, a frame for implementing gray levels of a stereoscopic image may include a plurality of sub-frames including at least one subfield. For example, as illustrated in FIG. 2, one frame may include a first sub-frame and a second sub-frame each including at least one subfield. Hereinafter, it will be assumed that the first subframe is a left eye subframe corresponding to the left eye lens, and the second subframe is a right eye subframe corresponding to the right eye lens. It is also possible for the positions of the first subframe and the second subframe to be interchanged. In addition, the number of subfields included in each subframe may be variously changed.

In addition, the subfield is a sustain period for implementing gradation according to an address period and a number of discharges for selecting a discharge cell in which discharge will not occur or a discharge cell in which discharge occurs. It may include.

For example, each of the first subframe and the second subframe includes seven subfields SF1-SF7 and SF8-SF14 to implement 128 gray levels, and each subfield includes an address period and a sustain period. can do.

Alternatively, at least one subfield of the plurality of subfields of the frame may further include a reset period for initialization. Preferably, the first subfield of each subframe may include a reset period in which a reset signal is supplied to the scan electrode.

Meanwhile, the weight of the corresponding subfield may be set by adjusting the number of sustain signals supplied in the sustain period. That is, a predetermined weight can be given to each subfield using the sustain period. For example, the weight of each subfield is 2 ⁿ by setting the weight of the first subfield to 2 ⁰ and the weight of the second subfield to 2 ¹ (where n = 0, 1, 2, 3, 4, 5, 6) can be set to increase. As described above, gray levels of various images may be realized by adjusting the number of sustain signals supplied in the sustain period of each subfield according to the weight in each subfield.

Here, FIG. 2 illustrates only the case where the number of subfields constituting the first subframe and the second subframe is the same, but the number of subfields constituting the first subframe and the second subframe is different. It is possible.

Also, in FIG. 2, subfields are arranged in increasing order of the weight in each subframe, but alternatively, subfields in each subframe may be arranged in decreasing order of weight, or weight Subfields may be arranged regardless.

Meanwhile, at least one of the plurality of subfields included in the subframe may be a selective erase subfield (SE), and at least one of the plurality of subfields may be a selective write subfield (SW). It is possible.

If the subframe includes at least one selective erase subfield and an optional write subfield, the first subfield or the first and second subfields of the plurality of subfields of the subframe are the selective write subfields, It may be desirable for the remainder to be selective erasure subfields.

Here, the selective erasing subfield is a subfield that turns off the discharge cells supplied with the data signal Data to the address electrodes in the address period in the sustain period after the address period.

The selective erasure subfield may include an address period for selecting a discharge cell to be turned off and a sustain period for generating sustain discharge in discharge cells not selected in the address period.

The selective write subfield is a subfield that turns on the discharge cells supplied with the data signal Data to the address electrodes in the address period in the sustain period after the address period.

The selective write subfield may include a reset period for initializing the discharge cells, an address period for selecting the discharge cells to be turned on, and a sustain period for generating sustain discharge in the discharge cells selected in the address period.

3 is a diagram for explaining an example of a driving waveform for driving a plasma display panel.

Referring to FIG. 3, the reset signal RS may be supplied to the scan electrode Y in a reset period RP for initializing at least one subfield among a plurality of subfields of a subframe. have. Here, the reset signal RS may include a rising ramp signal (Ramp-Up: RU) in which the voltage gradually rises and a falling ramp signal (Ramp-Down: RD) in which the voltage gradually falls.

For example, the rising ramp signal RU may be supplied to the scan electrode in the setup period SU of the reset period, and the falling ramp signal RD may be supplied to the scan electrode in the setdown period SD after the setup period. .

When the rising ramp signal is supplied to the scan electrode, a weak dark discharge, that is, setup discharge, occurs in the discharge cell by the rising ramp signal. By this setup discharge, the distribution of wall charges can be uniform in the discharge cells.

After the rising ramp signal is supplied, when the falling ramp signal is supplied to the scan electrode, a weak erase discharge, that is, a setdown discharge, occurs in the discharge cell. By this set-down discharge, wall charges such that address discharge can be stably generated can be uniformly retained in the discharge cells.

In the address period AP after the reset period, the scan reference signal Ybias having a voltage higher than the lowest voltage of the falling ramp signal may be supplied to the scan electrode.

In addition, in the address period, the scan signal Sc that falls from the voltage of the scan reference signal Ybias may be supplied to the scan electrode.

Meanwhile, the pulse width of the scan signal supplied to the scan electrode in the address period of at least one subfield may be different from the pulse width of the scan signal of another subfield. For example, the width of the scan signal in the subfield located later in time may be smaller than the width of the scan signal in the preceding subfield. In addition, the reduction of the scan signal width according to the arrangement order of the subfields can be made gradually, such as 2.6 Hz (microseconds), 2.3 Hz, 2.1 Hz, 1.9 Hz, or 2.6 Hz, 2.3 Hz, 2.3 Hz, 2.1 Hz. .... 1.9 ㎲, 1.9 ㎲ and so on.

As such, when the scan signal is supplied to the scan electrode, the data signal Dt may be supplied to the address electrode X corresponding to the scan signal.

When the scan signal and the data signal are supplied, an address discharge may be generated in the discharge cell to which the data signal is supplied while the voltage difference between the scan signal and the data signal and the wall voltage generated by the wall charges generated in the reset period are added. .

In addition, the sustain reference signal Zbias signal may be supplied to the sustain electrode in the address period in which the address discharge occurs so that the address discharge is effectively generated between the scan electrode and the address electrode.

In the sustain period SP after the address period, the sustain signal SUS may be supplied to at least one of the scan electrode and the sustain electrode. For example, a sustain signal may be alternately supplied to the scan electrode and the sustain electrode.

When such a sustain signal is supplied, the discharge cell selected by the address discharge is added with the wall voltage in the discharge cell and the sustain voltage Vs of the sustain signal, and a sustain discharge, i.e., display between the scan electrode and the sustain electrode when the sustain signal is supplied. Discharge may occur.

4 to 9 are drawings for explaining in detail the functional blocks and operation of the three-dimensional plasma display device. Hereinafter, the description of the parts described in detail above will be omitted. In addition, in the following, only the case in which the left eye subframe precedes the right eye subframe in one frame is different. Alternatively, the right eye subframe may precede the left eye subframe in one frame.

Referring to FIG. 4, the granular plasma display apparatus includes a plasma display panel 100, a data driver 101, a scan driver 102, a sustain driver 103, a stereoscopic glasses 300, and a timing controller 400. It may include.

In FIG. 4, only the case where the data driver 101, the scan driver 102, and the sustain driver 103 have different board shapes are illustrated. However, the data driver 101, the scan driver 102, and the sustain driver 103 have different board shapes. At least two of the drivers 103 may be formed or integrated in one borough. For example, it may be possible for the scan driver 102 and the sustain driver 103 to be formed on one board.

The data driver 101 may supply driving signals such as data signals to the address electrodes X1 to Xm of the plasma display panel 100.

The scan driver 102 may supply driving signals such as scan signals to the scan electrodes Y1 to Yn of the plasma display panel 100.

The sustain driver 103 may supply driving signals such as a sustain signal to the sustain electrodes Z1 to Zn of the plasma display panel 100.

The timing controller 400 may supply a predetermined timing control signal to the data driver 101, the scan driver 102, and the sustain driver 103 to control the timing of each driving signal.

In addition, the timing controller 400 may control the on / off of the left eye lens and the right eye lens of the stereoscopic glasses 300 by supplying a predetermined timing control signal to the stereoscopic glasses 300. In detail, the timing controller 400 may turn on the left eye lens corresponding to the left eye subframe, and turn on the right eye lens corresponding to the right eye subframe.

Preferably, the timing controller 400 supplies a timing control signal to the stereoscopic glasses 300 so that the turn-on time of the left eye lens is determined by the start of the reset period of the first subfield of the left eye subframe and the first subfield. The stereoscopic glasses 300 may be controlled to be positioned between the start points of the sustain period.

Hereinafter, the start time of the reset period is the supply time of the reset signal supplied to the scan electrode, the start time of the address period is the supply time of the scan reference signal supplied to the scan electrode, and the start time of the sustain period is the scan electrode or the sustain. It may be the point of supply of the first sustain signal supplied to the electrode.

For example, as in the case of FIG. 5, one frame includes a first sub-frame and a second sub-frame, and the first subfield of the first sub-frame, namely, Assume that the first subfield of the first subfield SF1 and the second subframe, that is, the eighth subfield SF8 includes a reset period RP, an address period AP, and a sustain period SP. Let's see. In addition, it is assumed that the first subframe is a left eye subframe according to the left eye image, and the second subframe is a right eye subframe according to the right eye image.

In this case, the left eye lens 301 of the stereoscopic glasses 300 may be turned on within the reset period of the first subfield SF1. That is, the turn-on time T1 of the left eye lens 301 may be located between the start time and the end time of the reset period of the first subfield SF1.

In addition, the right eye lens 302 of the stereoscopic glasses 300 may be turned on within the reset period of the eighth subfield SF8. That is, the turn-on time T2 of the right eye lens 302 may be located between the start time and the end time of the reset period of the eighth subfield SF8.

In addition, the left eye lens 301 and the right eye lens 302 may be turned off before the start time of the next subframe. For example, as shown in FIG. 5, the left eye lens 301 may be turned off before the start time of the second sub frame, and the right eye lens 302 may be turned off before the start time of the next frame.

Accordingly, a period D between the left eye lens 301 and the right eye lens 302 may be provided between the period during which the left eye lens 301 is turned on and the period during which the right eye lens 302 is turned on.

Alternatively, as in the case of FIG. 6, the left eye lens 301 of the stereoscopic glasses 300 may be turned on within the address period of the first subfield SF1. That is, the turn-on time point T1 of the left eye lens 301 may be located between the start point and the end point of the address period of the first subfield SF1.

In addition, the right eye lens 302 of the stereoscopic glasses 300 may be turned on within the address period of the eighth subfield SF8. That is, the turn-on time T2 of the right eye lens 302 may be located between the start time and the end time of the address period of the eighth subfield SF8.

That is, the turn-on time point T1 of the left eye lens 301 is located within an address period between the reset period and the sustain period of the first subfield SF1 of the left eye subframe, and the turn-on of the right eye lens 302 is turned on. The time point T2 is located within an address period between the reset period and the sustain period of the first subfield SF8 of the right eye subframe.

Alternatively, the left eye lens 301 and the right eye lens 302 may be turned on between the last scan signal and the first sustain signal of the left eye subframe or the right eye subframe, respectively.

For example, assume that the scan signals Scan are sequentially supplied to the plurality of scan electrodes Y1 to Yn as in the case of FIG. 7.

In this case, the left eye lens 301 in the period P between the end point of the scan signal supplied to the nth scan electrode Yn having the latest scan order among the plurality of scan electrodes Y1 to Yn and the start point of the sustain signal. ) Or the right eye lens 302 may be turned on.

That is, the turn-on time point T1 of the left eye lens 301 is supplied to the scan electrode or the sustain electrode in the sustain period and the last scan signal supplied to the scan electrode in the address period of the first subfield SF1 of the left eye subframe. The turn-on time point T2 of the right eye lens 302 is positioned between the first sustain signal, and the last scan signal and the sustain period supplied to the scan electrode in the address period of the first subfield SF8 of the right eye subframe. It can be located between the first sustain signal supplied to the scan electrode or the sustain electrode.

As described above, the reason why the turn-on time of the left eye lens 301 and the right eye lens 302 is positioned between the start time of the reset period of the first subfield of each subframe and the end time of the sustain period will be described. It looks like this:

8, a driving method according to the present invention and another comparative example is disclosed.

Referring to FIG. 8, in the comparative example, the turn-on time T1 of the left eye lens 301 is substantially the same as the start time of the first sub-frame, that is, the first subfield SF1 of the left eye subframe. The turn-on time T2 of the right eye lens 302 may be substantially the same as the start time of the second sub-frame, that is, the first subfield SF8 of the right eye subframe. have.

In this comparative example, the image according to the first subframe may be recognized not only through the left eye lens 301, but also through the right eye lens 302, and the image according to the second sub frame may include the left eye lens 301 as well as the right eye lens 302. It can also be recognized through). As a result, the viewer recognizes the image to be perceived as the left eye as the right eye and the image to be recognized as the right eye as well. That is, the cross-talk phenomenon of the image where the left and right eye images are mixed with each other. This can happen.

The crosstalk phenomenon of the image may be caused by the light emission characteristics of the phosphor. For example, when a discharge occurs in a G (Green) discharge cell, the G phosphor layer of the G discharge cell may not emit and stop green light instantaneously, but may steadily emit green light for a predetermined time. This may be referred to as the afterglow property of the phosphor.

Due to the afterglow characteristic of the phosphor, an image according to the first subframe may still remain at the start of the second subframe. Accordingly, when the turn-on time T2 of the right eye lens 302 is substantially the same as the start time of the first subfield SF8 of the second subframe, as shown in the comparative example of FIG. The right eye image can be mixed.

The crosstalk phenomenon of the image is that the turn-on time T1 of the left eye lens 301 is earlier than the start time of the first subfield SF1 of the first subframe, or the turn-on time of the right eye lens 302 ( If T2) is earlier than the start of the first subfield SF8 of the second subframe, it may be further deepened.

When the crosstalk phenomenon of the image occurs as described above, the image quality of the stereoscopic image implemented on the screen of the plasma display panel may be deteriorated.

On the other hand, as in the case of FIGS. 5 to 7, the turn-on time T1 of the left eye lens 301 is set to the start time and the first sub-set of the reset period of the first subfield SF1 of the first subframe. When placed between the beginning of the sustain period of the field SF1, the left eye lens 301 or the right eye lens 302 is turned on after the light generated in the phosphor layer is sufficiently dissipated, so that the crosstalk of the image The phenomenon can be reduced.

FIG. 9 shows schematic data of measuring crosstalk phenomena of an image of a comparative example and an embodiment according to the present invention.

In FIG. 9, the comparative example is the same as in FIG. 8, and the embodiment according to the present invention is the same as in FIG. 6. In addition, the experimental conditions of the data of FIG. 9 are as follows.

In the comparative example and the embodiment according to the present invention, the first subframe (left eye subframe) is image data for implementing a full-white image, and the second subframe (right eye subframe) is full-black ( Full Black) Image data that implements an image.

Under the above conditions, the luminance of the image according to the second sub-frame perceived by the right eye lens 302 at the turn-on time of the right eye lens 302 is measured. In this case, since the second subframe is image data according to the full-black image, the luminance of the image measured by the right eye lens 302 may be referred to as black luminance.

9, it can be seen that the black luminance in the embodiment according to the present invention is lower by ΔC than the black luminance in the comparative example.

That is, in the comparative example, the image according to the first subframe, which is full-white, remains until the turn-on time of the right eye lens 302, and the image according to the first subframe is turned on when the right eye lens 302 is turned on. Since the image is also recognized through the right eye lens 302, the black luminance is relatively high, and in the embodiment according to the present invention, the right eye lens 302 is turned off until the image according to the first sub-frame, which is full-white, is sufficiently extinguished. As it remains, the black luminance is relatively low.

Considering the data of FIG. 9, it can be seen that the embodiment according to the present invention reduces the crosstalk phenomenon of the image as compared with the comparative example.

10 to 11 are diagrams for explaining the structure of a frame. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 10, one frame may include one left eye subframe Sub-F1 and one right eye subframe Sub-F2. Here, positions of the left eye subframe Sub-F1 and the right eye subframe Sub-F2 may be changed.

In addition, the length of the period during which the left eye lens 301 and the right eye lens 302 are turned off together in one frame is the period during which the left eye lens 301 and the right eye lens 302 are turned off together between any two consecutive frames. May be different from the length of.

For example, as illustrated in FIG. 10, the first frame Frame 1 includes a first left eye sub-frame Sub-F1 and a first right eye sub-frame Sub-F2, and is a second continuous frame with the first frame. Assume that the frame Frame 2 includes a second left eye sub frame Sub-F3 and a second right eye sub frame Sub-F4.

In this case, the left eye lens 301 or the right eye lens 302 is turned on between the start of the reset period and the start of the sustain period in the first subfield of each subframe Sub-F1 to Sub-F4. Therefore, a period in which the left eye lens 301 and the right eye lens 302 are turned off together may be provided between each subframe. In detail, the left-eye lens may be disposed between the period in which the left eye lens 301 is turned on in the first left eye sub-frame Sub-F1 and the period in which the right eye lens 302 is turned on in the first right eye sub-frame Sub-F2. 301 and a first period D1 in which the right eye lens 302 is turned off together, and a period in which the left eye lens 301 is turned on in the second left eye subframe Sub-F3 and a second right eye subframe Sub In the period during which the right eye lens 302 is turned on, the second eye period D2 during which the left eye lens 301 and the right eye lens 302 are turned off is included, and the first right eye sub frame Sub-F2 is included. The left eye lens 301 and the right eye lens 302 are turned off together between a period during which the right eye lens 302 is turned on and a period during which the left eye lens 301 is turned on in the second left eye subframe Sub-F3). The third period D3 may be included.

In this case, the length of the third period D3 may be different from the length of at least one of the first period D1 and the second period D2. Preferably, the length of the third period D3 may be longer than the length of at least one of the first period D1 and the second period D2.

Referring to FIG. 11, one frame may include a plurality of left eye subframes Sub-F1 and Sub-F3 and a plurality of right eye subframes Sub-F2 and Sub-F4. In this case, the number of subfields included in each subframe Sub-F1 to Sub-F4 may be smaller than in the case of FIG. 10.

In addition, when one frame includes a plurality of left eye subframes Sub-F1 and Sub-F3 and a plurality of right eye subframes Sub-F2 and Sub-F4, the left eye subframes Sub-F1 and Sub-F- are included. F3) and the right eye subframes Sub-F2 and Sub-F4 may be alternately arranged. That is, the left eye subframe is disposed after the left eye subframe, and the left eye subframe is disposed after the right eye subframe.

In addition, it may be preferable that each subframe includes a plurality of subfields. For example, it may be preferable that one subframe consists of 4 to 8 subfields.

Alternatively, it may be possible that one subframe consists of one subfield.

As shown in FIG. 11, when a plurality of left eye subframes Sub-F1 and Sub-F3 and a plurality of right eye subframes Sub-F2 and Sub-F4 are included in one frame, the frames are consecutive in one frame. It is possible that the lengths of the periods during which the left eye lens 301 and the right eye lens 302 are turned off together between the two sub frames are substantially the same.

For example, the lengths of the first period D1, the second period D2, and the third period D3 in FIG. 11 may be substantially the same.
