The present invention relates to a plasma display panel driving method for a multi-screen that can be configured as a single circuit.

도 1은 본 발명에 따른 멀티스크린용 플라즈마 디스플레이 패널 장치를 나타낸 도면이다. 여기서는 멀티스크린용 플라즈마 디스플레이 패널 장치를 후면에서 본 개념도로써, 4개의 단위 PDP를 종횡으로 연접하여 하나의 멀티 화면을 구성하고, 설명의 편의를 위해 각 단위 PDP(11∼14)을 1사분면, 2사분면, 3사분면 및 4사분면으로 각각 설정한다.1 is a view showing a multi-screen plasma display panel device according to the present invention. Here, as a conceptual view of the plasma display panel device for the multi-screen, the four unit PDPs are connected horizontally and horizontally to form one multi-screen. Quadrants, three quadrants, and four quadrants are set.

또한, 각 단위 PDP(11∼14)는 480×53 픽셀로 구성되고, 입력된 영상신호를 256 계조 및 60Hz로 구동하는 경우를 예를 들어 설명한다.In addition, each unit PDP 11-14 is comprised by 480x53 pixel, and demonstrates the case where an input video signal is driven by 256 grayscales and 60Hz.

따라서 1사분면의 PDP(11)은 1∼480 스캔 라인과 1∼853 데이터 라인에 의해 형성되는 화면 영역을 표시하고, 2사분면의 PDP(12)는 1∼480 스캔 라인과854∼1706 데이터 라인에 의해 형성되는 화면 영역을 표시하고, 3사분면의 PDP(13)는 481∼960 스캔 라인과 1∼853 데이터 라인에 의해 형성되는 화면 영역을 표시하고, 4사분면의 PDP(24)는 481∼960 스캔 라인과 854∼1706 데이터 라인에 의해 형성되는 화면 영역을 표시한다.Therefore, the PDP 11 of the first quadrant displays a screen area formed by 1 to 480 scan lines and the 1 to 853 data lines, and the PDP 12 of the second quadrant has 1 to 480 scan lines and 854 to 1706 data lines. Screen area formed by the second quadrant PDP 13 displays the screen area formed by the 481 to 960 scan lines and the 1 to 853 data lines, and the four quadrant PDP 24 displays the 481 to 960 scans A screen area formed by lines and data lines 854-1706 is displayed.

본 발명에 따른 멀티스크린용 플라즈마 디스플레이 패널 장치는, 입력된 영상신호(video signal) S를 디지털 신호(RGB) D로 변환하여 각 단위 PDP(11∼14)를 구동하는 신호를 생성하는 영상 처리부(10)와, 멀티 화면을 구성하는 4개의 단위 PDP(11∼14)와, 해당하는 단위 PDP(11∼14)를 구동하는 4개의 구동 회로(21∼24)를 포함한다.The multi-screen plasma display panel device according to the present invention includes an image processing unit for converting an input video signal S into a digital signal RGB D to generate a signal for driving each unit PDP 11 to 14 ( 10), four unit PDPs 11 to 14 constituting a multi-screen, and four drive circuits 21 to 24 for driving the corresponding unit PDPs 11 to 14 are included.

여기서, 영상 처리부(10)는 입력된 영상 신호 S를 디지털 신호 D로 변환하는 아날로그/디지털 변환기(analog/digital convertor; 이하 ADC라 한다)(20)와, 디지털 신호 D를 저장하는 버퍼(30)와, 버퍼(30)에 저장된 디지털 신호 D를 해당하는 영역을 표현하는 디지털 신호 D를 해당 구동회로(21∼24)로 출력하는 확대 처리부(40)를 포함하다.The image processor 10 may include an analog / digital convertor (ADC) 20 for converting an input image signal S into a digital signal D, and a buffer 30 for storing the digital signal D. And an enlargement processor 40 for outputting the digital signal D representing the area corresponding to the digital signal D stored in the buffer 30 to the driving circuits 21 to 24.

도 2는 도 1에 도시된 블록도에서 구동회로의 상세 블록을 나타낸 도면이다.FIG. 2 is a detailed block diagram of a driving circuit in the block diagram of FIG. 1.

각 구동회로(21∼24)는 영상 처리부(10)의 디지털 신호 D를 이용하여 전체 화면의 해당하는 영역을 표시하는 디지털 보드(31)와, 해당하는 단위 PDP(11∼14)의 수평 전극 라인(데이터(어드레스) 전극)을 구동하는 데이터 구동부(32)와, 해당하는 단위 PDP(11∼14)의 수직 전극 라인(스캔(Y 및 X) 전극)을 구동하는 스캔 구동부(33)를 포함한다.Each of the driving circuits 21 to 24 uses a digital signal D of the image processing unit 10 to display a corresponding area of the entire screen, and a horizontal electrode line of the corresponding unit PDPs 11 to 14. And a data driver 32 for driving (data (address) electrodes), and a scan driver 33 for driving vertical electrode lines (scan (Y and X) electrodes) of the corresponding units PDPs 11-14. .

이때, 상기 각 디지털 보드는 하나로 통합될 수 있으며, 영상처리부에 통합될 수도 있다.In this case, each of the digital boards may be integrated into one, or may be integrated into the image processing unit.

본 발명에 따른 멀티스크린용 플라즈마 디스플레이 패널은 각 화상 신호 변환 단계에서 전체 화면에 대해 동일한 변환을 하는 것이 아니라 화면을 다수의 영역으로 분할하고 각 영역에 대해 화상신호 변환을 다르게 하여 다수의 영역의 화질을 균일하게 하는 방법을 사용한다.In the multi-screen plasma display panel according to the present invention, instead of performing the same conversion for the entire screen in each image signal conversion step, the screen is divided into a plurality of areas and the image signal conversion is changed for each area so that the image quality of the plurality of areas is different. Use a method to make it uniform.

이와 같이 구성된 본 발명에 따른 멀티스크린용 플라즈마 디스플레이 패널 장치의 화면 조정 방법을 설명하면 다음과 같다.The screen adjustment method of the multi-screen plasma display panel device according to the present invention configured as described above is as follows.

전체 화면을 다수의 영역(1사분면, 2사분면, 3사분면, 4사분면)으로 나누고, 각 영역별로 화면 조정을 한다.The whole screen is divided into a plurality of regions (one quadrant, two quadrants, three quadrants, and four quadrants), and the screen is adjusted for each region.

즉, 영상처리부 또는 구동회로의 메모리 장치에 저장된 프레임(frame)을 영역별로 구분하고 각 영역마다 변경 가능한 상수를 지정하여, 상수 값을 영역별로 따로 설정하여 각 영역별로 화면 조정을 한다.That is, frames stored in the memory of the image processing unit or the driving circuit are divided for each area and a constant that can be changed for each area is set, and constant values are set for each area to adjust the screen for each area.

예를 들어, 백색(white) 색좌표 조정은, 4개의 단위 PDP(11∼14)의 RGB의 휘도 및 색좌표가 다를 수 있기 때문에, RGB의 출력 펄스를 조정하여 백색 색좌표를 맞춘다.For example, in the white color coordinate adjustment, since the luminance and color coordinates of the RGB of the four units PDPs 11 to 14 may be different, the white color coordinates are adjusted by adjusting the output pulses of the RGB.

입력 계조가 XR, XG, XB라고 가정하면, 4개의 단위 PDP(11∼14)에 대해 r(i), g(i), b(i) 값을 결정함으로써, 4개의 단위 PDP(11∼14)에 대한 출력 펄스 YR(i), YG(i), YB(i)를 결정한다.Assuming that the input gray levels are XR, XG, and XB, the four unit PDPs 11 to 14 are determined by determining the r (i), g (i), and b (i) values for the four unit PDPs 11-14. Determine the output pulses YR (i), YG (i), and YB (i).

이를 수학식으로 표현하면 [수학식 1]과 같다.This may be expressed as Equation 1 below.

[수학식 1][Equation 1]

또한, 백색(white) 휘도 조정은, 상기와 같은 방법에 의해 색좌표를 조정하였지만, 동일 백색 계조에서 휘도가 다를 수 있기 때문에, 입력계조 X가 "0"인 상태에서, 출력계조 Y(i)가 "0"이 되도록 블랙 레벨 계수(black level) B(i)를 설정하고, 입력계조 X가 "255"일 때 4개의 출력계조 Y(i)가 동일하도록 화면 조절 계수(picture control constant) C(i)를 각각 설정한다.In the white luminance adjustment, the color coordinates are adjusted by the same method as described above, but the luminance may be different in the same white gradation, so that the output gradation Y (i) is set in the state where the input gradation X is "0". Set the black level B (i) to be "0", and set the picture control constant C (4) so that the four output gradations Y (i) are equal when the input gradation X is "255". Set i) respectively.

이를 수학식으로 표현하면 [수학식 2]와 같다.If this is expressed as equation (2).

[수학식 2][Equation 2]

여기서, Y(i)는 출력계조, C(i)는 화면 조절 계수(picture control constant), B(i)는 블랙 레벨 계수(black level constant)를 나타내고, a, b, c, d는 상수이다.Where Y (i) is an output gradation, C (i) is a picture control constant, B (i) is a black level constant, and a, b, c, and d are constants. .

따라서 0∼255 계조로 표현되는 값에 각 영역별로 r(i), g(i), b(i), C(i), B(i) 값을 지정할 수 있고, 지정된 상수에 따라 계조 값을 변환하여 새로운 프레임을 형성함으로써, 4개의 영역의 화면을 균일하게 조정할 수 있다.Therefore, r (i), g (i), b (i), C (i), and B (i) values can be assigned to each value in the range of 0 to 255 gradations. By converting to form a new frame, the screens of the four areas can be adjusted uniformly.

여기서는 각 구동회로(21∼24)의 디지털 보드(31)에서 상기와 같은 계산 알고리즘을 수행할 수 있도록 구성한 경우를 예를 들어 설명하였다.Here, a case where the digital board 31 of each of the driving circuits 21 to 24 is configured to perform the above calculation algorithm is described as an example.

상기와 같은 계산을 수행하는 계산 알고리즘을 구동회로(21∼24)의 디지털 보드(31)에 구현할 수 없는 경우, 각각 변환에 대한 결과 값을 LUT(look up table)에 저장하여 사용함으로써 4개의 영역의 화면을 균일하게 조정할 수 있다.If the calculation algorithm for performing the above calculation cannot be implemented in the digital board 31 of the driving circuits 21 to 24, four areas are stored by using the result values of the conversion in LUTs (look up table). The screen can be adjusted uniformly.

즉, 단위 PDP와 구동회로를 제조한 후 출하 전에 측정기에 의한 검사를 통하여 각 단위 PDP의 계조 값을 검출하여 그 결과 값을 LUT에 저장하여 메모리에 입력한다.That is, after manufacturing the unit PDP and the driving circuit, the gray scale value of each unit PDP is detected through inspection by a measuring device before shipment and the result value is stored in the LUT and input into the memory.

여기서는 백색 색좌표 및 휘도 조정에 대한 방법을 설명하였지만, 화면 균일성에 영향을 미치는 감마(Gamma) 값, APL(Average Picture Level) 수치 등도 동일한 방법에 의해 계산 알고리즘을 통해 설정하거나 LUT에 저장하여 화면을 균일하게 조정할 수 있다.Although the method of adjusting white color coordinate and luminance is described here, the gamma value and average picture level (APL) value affecting the screen uniformity are set through the calculation algorithm or stored in the LUT by the same method. Can be adjusted.

이상에서 살펴본 바와 같이, 본 발명에 따른 멀티스크린용 플라즈마 디스플레이 패널 장치는 다수의 PDP를 사용하는 경우 각 PDP 간의 화면 편차를 영역별로 화면 조정을 수행하여 균일한 전체 화면을 표현할 수 있기 때문에, 각 PDP에 해당하는 구동회로에서 중복 사용되는 회로들을 단일회로로 구성할 수 있는 효과가 있다.As described above, in the case of using a plurality of PDPs, the multi-screen plasma display panel device may display the entire screen by adjusting the screen deviation between the PDPs for each region. There is an effect that a circuit can be configured as a single circuit that is used in duplicate in the driving circuit corresponding to the.

중복 사용을 줄일 수 있는 회로들은 영상처리부, 디지털보드, 구동회로, 전원공급부 등이 가능하다.Circuits that can reduce redundancy can be image processing units, digital boards, driving circuits, and power supply units.
