Description
본 발명은, 플라즈마 표시장치의 구동방법과 그 장치에 관한 것으로, 더 상세하게는 제조된 PDP의 어드레스(ADDRESS)마진이 부분적으로 상이할 경우 이에 상응하는 전압을 인가하여 어드레스할 수 있도록 PDP의 마진을 보완할 수 있는 플라즈마 표시장치의 구동방법과 그 장치에 관한 것이다.The present invention relates to a method of driving a plasma display device and a device thereof, and more particularly, a margin of a PDP to be addressed by applying a corresponding voltage when the address of the manufactured PDP is partially different. The present invention relates to a driving method of a plasma display device and a device thereof.
도 1에는 본 발명이 관련되는 플라즈마 표시장치의 구동장치의 구성이 블록도로서 도시된다.1 is a block diagram showing a configuration of a driving apparatus of a plasma display device according to the present invention.
도 1에서 메트릭(MATRIX) 구조의 PDP는 X축과 Y측이 서로 교차하는 지점에서 셀(CELL)이 형성되며, 이들 셀(CELL)은 각각 일정한 전압 특성, 가령 방전 개시전압, 유지전압, 어드레스(ADDRESS) 전압 등을 갖고 있으며, 어드레스 전압 및 방전 유지전압을 예로 든다면 이상적으로는 도 3에 도시된 바와 같이 각각의 셀 어드레스 전압이 그 최대와 최소의 전압(Vamax,Vamin)의 분포가 동일한 것이며, 어드레스 전압이 Vamin 이하의 전압인 경우, 어드레싱(addressing)이 이루어지지 않으며 또 Vamax 이상인 경우 과도한 어드레싱이 이루어지게 되므로, 모든 셀의 전압 분포가 일치하여야 그 전압의 마진이 커지게 된다.In FIG. 1, a cell CELL is formed at a point where the X-axis and the Y-side cross each other, and each cell CELL has a constant voltage characteristic, for example, a discharge start voltage, a sustain voltage, and an address. (Address) and discharge sustain voltage, ideally, as shown in FIG. 3, each cell address voltage has the same distribution of the maximum and minimum voltages (Vamax, Vamin). If the address voltage is less than Vamin, addressing is not performed, and if the address voltage is greater than Vamax, excessive addressing is performed. Therefore, the voltage distribution of all cells must match to increase the margin of the voltage.
그러나, 실제로는 이와 같이 이상적인 상태의 PDP구현은 어려우며, 도 4 및 도 5에 도시된 바와 같이 각 셀별로 차이를 나타내게 된다. 이로 인하여 종래의 도 2와 같은 어드레스 드라이브 보드(PCB)를 사용하는 경우, 전압의 마진(margin)이 적어지게 되는데, 도 4의 셀의 어드레스 전압의 분포인 경우 어드레스 전압범위는 e) 와 d)사이의 범위로 한정되며, 도 3과 같은 이상적인 경우에 비해 좁다는 문제가 있다.However, in practice, the ideal state of the PDP implementation is difficult, and as shown in FIG. 4 and FIG. 5, the difference is shown for each cell. Therefore, when using the conventional address drive board (PCB) as shown in Figure 2, the margin of the voltage (margin) is reduced, in the case of the distribution of the address voltage of the cell of Figure 4 the address voltage range is e) and d) It is limited to the range between and has a problem that it is narrow compared to the ideal case as shown in FIG.
또, 이와 같이 실제로 표시된 분포를 벗어난 셀들이 존재하게 되어 어드레싱이 이루어지지 않게 되거나 과도한 어드레싱이 일어나게 되는데, 그 수가 PDP의 전체 표시면에서 10 포인트(POINT) 이상인 경우 불량으로 판정하게 된다.In addition, there are cells outside the distribution actually displayed as described above so that addressing is not performed or excessive addressing occurs. When the number is 10 points or more in the entire display surface of the PDP, it is determined to be defective.
따라서 전압 범위 결정은 전압을 변동시켜 가면서 어드레싱이 이루어 지지않는 셀과 과도한 어드레싱이 이루어지는 셀의 수를 비교하여 그 수가 적은 쪽으로 결정해야 된다는 문제가 있다.Therefore, the voltage range determination has a problem in that the number of cells that are not addressed and the cells that are excessively addressed while varying the voltage must be compared and the number is determined to be smaller.
예를들어 도 5의 셀 분포의 경우, 좌측부분의 셀들은 우측부분의 셀에 비하여 그 전압 범위가 높아, 좌측 부분의 2,3,4,5,6번째 셀을 기준으로 하여 전압을 인가하면, 그 전압은 7,8,10-20,22,24번째의 셀 전압보다 과도한 전압이 되게 되며, 또 7,8,10-20,22,24번째의 셀을 기준으로 하여 전압을 인가하면 그 전압은 2,3,4,5번째 셀의 Vamin에 미치지 못하므로 데이터 기입이 이루어 지지 못하게 된다. 특히 2,3,4,5,6번째의 특성가 같은 셀이 10개 이상 존재 하는 경우는 불량으로 처리하여 패널을 사용하지 않게 된다.For example, in the cell distribution of FIG. 5, the cells in the left part have a higher voltage range than the cells in the right part, and when a voltage is applied based on the second, third, fourth, fifth, and sixth cells of the left part, When the voltage is applied to the 7,8,10-20,22,24th cell, the voltage becomes excessive than the 7,8,10-20,22,24th cell voltage. Since the voltage does not reach Vamin of the 2nd, 3rd, 4th, and 5th cells, data writing cannot be performed. In particular, when 10 or more cells with the same characteristics of the 2nd, 3rd, 4th, 5th, and 6th exist, the panel is treated as defective and the panel is not used.
종래의 구동방법은 전체 셀의 전압 분포를 측정하여 분포전압이외의 셀이 10개보다 많거나 부분적으로 집중되어 있는 경우는 불량으로 처리하므로 실제 패널의 수율이 떨어지며, 특히 부분적인 집중으로 인한 불량이 많은 실정이다.The conventional driving method measures the voltage distribution of the entire cell and treats the defective cell if there are more than 10 or partially concentrated cells other than the distribution voltage, so the yield of the actual panel is lowered. It is a lot.
따라서, 본 발명은, 이러한 문제를 해결하기 위한 것으로, 전압 분포가 현격하게 다른 셀들의 분포는 PDP 전면에 고르게 분포하는 것이 아니라, 어느 한쪽 부분에 집중적으로 나타나고 있는 점에 착안하여 이러한 부분적인 전압 편차가 큰 부분의 구동시에 이에 상응하는 전압을 안가함으로써 이러한 형태의 PDP를 활용할 수 있도록 한 플라즈마 표시장치의 구동방법과 그 장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention is to solve this problem, the distribution of cells with a significantly different voltage distribution is not evenly distributed over the front surface of the PDP, focusing on the fact that it appears concentrated on either side, such partial voltage deviation It is an object of the present invention to provide a method and a driving method of a plasma display device in which a PDP of this type can be utilized by applying a corresponding voltage when driving a large portion thereof.
즉, 본 발명은, PDP의 활용을 증가시키고 마진을 증가시키기 위한 것으로, 어드레스 편차에 따른 패널의 표시 품위 저하를 보완할 수 있고 심지어는 어드레스 마진이 적어 사용이 불가능한 패널도 사용이 가능하게 되어 제조된 PDP의 어드레스(ADDRESS)마진이 부분적으로 상이할 경우 이에 상용하는 전압을 인가하여 어드레스할 수 있도록 PDP의 마진을 보완할 수 있게 된다.That is, the present invention is to increase the utilization of the PDP and increase the margin, and can compensate for the deterioration of the display quality of the panel due to the address variation, and even the panel, which cannot be used due to the low address margin, can be used. If the address (ADDRESS) margin of the PDP is partially different, it is possible to supplement the margin of the PDP to be addressed by applying a commercial voltage.

PCB: 어드레스 구동 보드 C: 전압조절회로PCB: address drive board C: voltage regulation circuit
이러한 목적을 달성하기 위해 본 발명의 일실시예에 따른 플라즈마 표시장치의 구동방법은, 복수의 셀로 구성된 플라즈마 표시장치의 구동방법에 있어서, 전압 분포가 현격하게 다른 셀들을 그룹화하여 그 전압분포에 상응하는 전압이 인가되도록 어드레스 전압을 그룹별로 조정하여 인가하는 것을 특징으로 한다.In order to achieve the above object, a method of driving a plasma display device according to an exemplary embodiment of the present invention is a method of driving a plasma display device including a plurality of cells, in which cells having significantly different voltage distributions are grouped to correspond to the voltage distribution. It is characterized in that the address voltage is adjusted for each group so as to be applied.
또한, 본 발명은 상술한 방법을 실현하기 위해 복수의 셀로 구성된 플라즈마 표시장치의 구동장치에 있어서, 전압 분포가 현격하게 다른 셀들을 그룹화하여 그 전압분포에 상응하는 전압이 인가되도록 각 어드레스 드라이브 보드에 전압조절회로를 구비하는 것을 특징으로 하는 플라즈마 표시장치의 구동장치를 제공한다.In addition, the present invention provides a driving apparatus for a plasma display device composed of a plurality of cells in order to realize the above-described method, in which each cell having a significantly different voltage distribution is grouped so that a voltage corresponding to the voltage distribution is applied to each address drive board. Provided is a driving device for a plasma display device comprising a voltage regulating circuit.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 6에는 본 발명의 일실시예에 따른 종래의 플라즈마 표시장치의 구동장치의 구성이 블록도로서 도시되며, 도 7에는 도 6의 전압조절회로의 구체적 구성이 회로도로서 도시되고, 도 8에는 본 발명에 따라 인가되는 조정전압의 파형도가 도시된다.FIG. 6 is a block diagram showing a configuration of a driving apparatus of a conventional plasma display device according to an embodiment of the present invention. FIG. 7 is a circuit diagram showing a specific configuration of the voltage regulating circuit of FIG. A waveform diagram of the adjustment voltage applied in accordance with the invention is shown.
도 1에서 우측 상단 부분의 전압이 다른 부분에 비해 상대적으로 전압 분포가 넓은 경우가 나타나는 때에 종래에는 그 셀의 수가 많아 사용이 불가능하고 이를 보완하기 위해 어드레싱(addressing)을 실시함에 있어 이에 해당하는 y축 부분의 전압을 높게 하면 우측 상단부만이 아니라 우측 하단부도 높은 전압이 인가되는 단점이 있었다.In FIG. 1, when the voltage distribution in the upper right portion is relatively wider than other portions, the number of cells is conventionally large, and thus, the number of cells is not available. Therefore, the corresponding y in addressing is compensated for. Increasing the voltage of the shaft portion has a disadvantage in that a high voltage is applied not only to the upper right portion but also to the lower right portion.
따라서, 본 방법은 부분적으로 전압을 보상하되, 해당하는 영역에 대해서만 보상하는 방법으로 어드레스 기간동안에 일정 부분만을 다른 전압으로 구동하는 것이다.Therefore, the method partially compensates the voltage, but only compensates for the corresponding region, and drives only a portion of the voltage to another voltage during the address period.
도 1에 도시된 바와 같이 상하에 어드레스 드라이브 보드(PCB)가 있고 우측 상단 부분의 전압이 높을 경우를 예를들면 다음과 같다.For example, as shown in FIG. 1, there is an address drive board (PCB) above and below and the voltage of the upper right portion is high.
종래에는 어드레스 드라이브 보드(PCB)가 도 2에 도시된 바와 같이 구성되어 있어 파우어(power)부분에 일정한 전압이 가해지고 이 전압이 다시 사각형으로 도시된 드라이브용 IC를 통해 패널에 가해지게 되며, 이에 따라 전압 조절이 불가능했고, 또 외부전압인 Power를 조절하여 전압을 공급한다해도 일정 부분이 아닌 전체 연결 부분에 전압이 인가되어 부분적인 조절이 불가능하다.In the related art, an address drive board (PCB) is configured as shown in FIG. 2 so that a constant voltage is applied to a power portion, and this voltage is applied to a panel through a drive IC shown in a square again. As a result, it was impossible to adjust the voltage, and even if the voltage is supplied by adjusting the external voltage, the voltage is applied to the entire connection part, not a part, so that partial adjustment is impossible.
가령 도 1의 우측상하에 있는 어드레스 드라이브 보드(PCB4)의 전압을 달리하여 공급한다면 우측상단부분에만 전압을 선택적으로 공급할 수 없고 어드레스 드라이브 보드(PCB4)가 연결된 부분의 셀들에 전체적으로 같은 전압이 인가되어 부분적인 전압공급 내지 전압 보상이 어렵다.For example, if the voltage of the address drive board PCB4 on the upper right and lower sides of FIG. 1 is supplied differently, the voltage cannot be selectively supplied only to the upper right part, and the same voltage is applied to the cells of the part to which the address drive board PCB4 is connected. Partial voltage supply or voltage compensation is difficult.
본 발명은, 도 6에 도시된 바와 같이 전압 조절단자와 함께 전압조절회로(C)를 추가하여 조절단자를 제어하면, 부분적인 전압의 제어가 가능하도록 구성한 것이다.According to the present invention, as shown in FIG. 6, when the voltage adjusting circuit C is added together with the voltage adjusting terminal to control the adjusting terminal, partial voltage control is possible.
가령, 도 1에서 상하의 어드레스 드라이브 보드(PCB4) 부분과 Y전극의 Y1∼Y45번까지 교차되는 부분의 어드레스 전압이 낮은 경우라면 PDP 세트를 프로그램하여 전압을 제어할 수 있다. 즉, 데이타의 어드레싱기간에서 도 7에 도시된 바와 같이 스켄라인(Scan line) 1번(H신호 1)부터 45번(H신호 45)사이의 시간에 도 7의 전압조절회로(C)의 입력 컨트롤신호(C1)을 하이 신호로 인가토록 하여 인가되는 전압이 표준보다 낮게 하도록 한다.For example, in the case where the address voltage of the upper and lower address drive board PCB4 and the portion of the Y electrode crossing Y 1 to Y 45 in FIG. 1 is low, the PDP set may be programmed to control the voltage. That is, in the addressing period of the data, as shown in FIG. 7, the input of the voltage regulating circuit C of FIG. 7 is performed at a time between scan line No. 1 (H signal 1) to No. 45 (H signal 45). The control signal C1 is applied as a high signal so that the applied voltage is lower than the standard.
이 때, 입력 컨트롤신호(C1,C2)는 프로그램된 컨트롤러에 의해 인가하도록 구성된다.At this time, the input control signals C1 and C2 are configured to be applied by a programmed controller.
도 7에서 Vin이 입력될 때, Vout 전압은, 1) Q1,Q2가 오프된 경우 Vo=Vz1+Vz2+Vz3로 되고, 2) Q2만이 온인 경우 Vo=Vz1+Vz2로 되며, 3) Q1만이 온인 경우 Vo=Vz1으로 된다.When Vin is input in FIG. 7, Vout voltage is 1) Vo = Vz 1 + Vz 2 + Vz 3 when Q1 and Q2 are off, and 2) Vo = Vz 1 + Vz 2 when only Q2 is on. , 3) Vo = Vz 1 when only Q1 is on.
따라서, 표준전압을 2)의 상태인 Vo=Vz1+Vz2로 볼 때, 표준전압보다 높은 전압을 인가하려면, Q1,Q2를 오프로 하고, 낮은 전압을 인가하려면, Q1을 온으로 함으로써 조절된 전압이 인가될 수 있게 된다.Therefore, when the standard voltage is 2), Vo = Vz 1 + Vz 2 , Q1 and Q2 are turned off to apply a voltage higher than the standard voltage, and Q1 is turned on to apply a low voltage. The applied voltage can be applied.
이상에서 설명한 본 발명의 실시예에 따른 플라즈마 표시장치의 구동방법과 그 장치의 구성과 작용에 의하면, 셀들의 어드레스 전압을 그룹화하고, 이에 대응되게 전압을 인가함으로써 PDP패널의 부분적인 편차를 보완하여 줄 수 있고, 나아가 패널의 표시 품위를 높일 수 있는 등의 효과가 있다.According to the driving method of the plasma display device according to the embodiment of the present invention described above and the configuration and operation of the device, the partial variation of the PDP panel is compensated by grouping the address voltages of the cells and applying the voltages accordingly. It is possible to increase the display quality of the panel, and the like.
