Description

화소배열구조 및 이를 채용한 액정표시소자 및 그의 구동방법Pixel array structure, liquid crystal display device employing the same, and driving method thereof

본 발명은 수평방항으로 길게 연장된 R, G, B 단위화소가 수직방향으로 배열된 화소배열구조 및 이를 채용한 액정표시소자와 그의 구동방법에 관한 것이다.The present invention relates to a pixel array structure in which R, G, and B unit pixels extending in a horizontal direction are arranged in a vertical direction, a liquid crystal display device employing the same, and a driving method thereof.

이 화소둘은 제1도(A)-(C)에 도시된 바와같이 RGB 스트라이프(stripe), RGB모자이크(mosaic), 그리고 RGB 델타(de1ta) 등의 방식으로 배열되어진다. RGB 스트라이프방식은 각 열(ROW)에서 단위화소가 R, G, B 순으로 배열되고, RGB 모자이크방식은 제1열에서는 단위화소가 R, G, B 의 순으로, 제2열에서는 G, B, R 의 순으로, 제3열에서는 B, R, G 순으로 반복배열된다. 그리고, 델타방식은 R, G, B 단위화소가 우수열에서 기수열에서 일정간격만큼 벗어나 반복배열되는 구조를 갖는다.These pixels are arranged in the manner of an RGB stripe, an RGB mosaic, and an RGB delta as shown in Figs. 1A-C. In the RGB stripe method, the unit pixels are arranged in the order of R, G, and B in each row. In the RGB mosaic method, the unit pixels are in the order of R, G, and B in the first column, and G and B in the second column. , R in order, and in the third column, B, R, G are arranged in order. In addition, the delta method has a structure in which R, G, and B unit pixels are repeatedly arranged apart from the odd column by a predetermined interval in the even column.

그러나, 일반적인 시각정보의 대부분은 수직방향보다는 수평방향으로 많은 움직임을 가지고 있으므로, 제1도에 도시된 바와같은 단워화소 구조를 사용하게 되면, 화상이 자연스럽지 못하게 되는 문제점이 있었다. 따라서, 수평방항의 옴직임이 많은 대부분의 정보를 화면상에 디스플레이하는 데 있어서, 자연스러은 화상을 얻기 위해서는 그 만큼 해상도를 높여야 하는 문제점이 있었다.However, since most of the general visual information has a lot of movement in the horizontal direction rather than the vertical direction, there is a problem that the image is not natural when using the simple pixel structure as shown in FIG. Therefore, in displaying most of information on a screen with a lot of horizontality, there is a problem that the resolution must be increased by that amount in order to obtain an image naturally.

1(A)-(C)는 일반적인 액정표시소자의 단위화소의 배열상태를 나타낸 도면,1 (A)-(C) is a diagram showing an arrangement of unit pixels of a general liquid crystal display device;

상기 목적을 달성하기 위하여, 본 발명은 각각 R, G, B 단위화소로 구정된 복수개의 화소가 열과 형의 매트릭스 형태로 배열된 화소배열구조에 있어서, 각 R, G, B 단위화소가 수직방향보다 수평방향으로 길게 연장된 형태를 갖으며, 각 화소는 R, G, B 단위화소가 수직방향으로 배열되는 것을 특징으로 한다.단위화소가 수직방향보다 수평방향으로 길게 연장된 형태를 갖으며, 각 칼라필더화소는 R, G, B 단위화소가 수직방향으로 배열되고, 각 데이터 라인은 칼라필터 화소의 열측을 따라 배열되며, 칼라필터 화소구동용 TFT는 각 칼라필터에 대응하여 데이터 라인의 일측에 하나씩 배열되는 것을 특징으로 한다.으로 한다.시간(=1/f, 여기서 f는 프레임 주파수)을 3으로 나누고, 각각의 1/3 프레임시간(=1 필드) 동안에 전채 패널의 각 R, G, B 단위화소들이 주사되는 방식이다.In order to achieve the above object, the present invention provides a pixel array structure in which a plurality of pixels, each of which is defined as R, G, and B unit pixels, are arranged in a matrix form of columns and shapes, wherein each R, G, and B unit pixels are in a vertical direction. It has a longer form in the horizontal direction, each pixel is characterized in that the R, G, B unit pixels are arranged in the vertical direction. The unit pixel has a form extending in the horizontal direction than the vertical direction, Each color filter pixel has R, G, and B unit pixels arranged in a vertical direction, and each data line is arranged along the column side of the color filter pixel, and the color filter pixel driving TFT corresponds to each color filter on one side of the data line. It is characterized by being arranged one by one. Time (= 1 / f, where f is the frame frequency) is divided by three, and each R, G of the fore panel during each 1/3 frame time (= 1 field). , B unit pixels are scanned The formula:

그리고, 제3도에 도시된 바와같이 동일 프레임의 각 필드에서 동일주사선에 각각 인가되는 R신호, G신호, B신호사이에는 위상이 서로 반전되며, 각 프레임의 동일 필드에서 소정의 주사라인에 인가되는 R, G, B 신호는 각각 이전의 주사라인에 인가되는 R, G, B 신호에 대해서 위상반전된다. 에를 들면, 제1프레임의 각 필드에서 제1주사라인에 인가되는 R 신호, G 신호, 그리고 B 신호는 각각 +, -, +의 위상을 가지므로, R 신호에 대해 G 신호는 워상반전되고, B 신호는 G 신호에 대해 위상반전된다. 또한, 각 프레임의 제1필드에서 제1주사라인과 제2주사라인에 각각 인가되는 R 신호는 각각 +, -, +의 위상을 갖고, G 신호는 -, +, -의 위상을 갖으며, B 신호는 +, -, +의 위상을 가지므로, 소정주사라인의 각 R, G, B 신호는 이전 주사라인의 R, G, B 신호에 대하여 반대위상을 갖게 된다.을 방지할 수 있다.As shown in FIG. 3, phases are inverted between R signals, G signals, and B signals respectively applied to the same scan line in each field of the same frame, and applied to a predetermined scan line in the same field of each frame. R, G, and B signals are inverted with respect to R, G, and B signals applied to the previous scan lines, respectively. For example, since the R signal, the G signal, and the B signal applied to the first scan line in each field of the first frame have phases of +,-, and +, respectively, the G signal is inverted relative to the R signal. The B signal is inverted with respect to the G signal. In addition, in the first field of each frame, the R signal applied to the first scan line and the second scan line, respectively, has a phase of +,-, +, and the G signal has a phase of-, +,-, Since the B signal has a phase of +,-, +, each of the R, G, and B signals of the predetermined scan line has an opposite phase with respect to the R, G, and B signals of the previous scan line.

상술한 바와 같은 본 발명의 액정표시소자는 수직방향보다 수평방향으로 긴단위화소 구조를 채택함으로써 수평방향의 움직임이 대부분인 영상신호의 화질을 재선시킬 수 있으며, 이는 수직방향으로 긴 통상의 단위화소구조를 채용한 TFT-LCD에서 화상도를 증가시킨 것과 등열한 효과를 얻을 수 있다. 또한, 상기와 같이 수평방향으로 긴 단위화소를 갖는 화소를 델타방식으로 배열항으로써 영상신호의 곡선처리를 자연스럽게 할 수 있는 이점이 있다. 상기와 같은 화소구조를 채택한 액정패널은 특히 동화상(動畵像)처리에 유리한 이점이 있다.As described above, the liquid crystal display device of the present invention adopts a unit pixel structure that is longer in the horizontal direction than the vertical direction, thereby re-drawing the image quality of the video signal having the most horizontal motion, which is a general unit pixel structure that is long in the vertical direction. In the TFT-LCD adopting the same, the effect of increasing the degree of image can be obtained. In addition, by arranging pixels having unit pixels long in the horizontal direction in the delta manner as described above, there is an advantage in that the curve processing of the video signal can be naturally performed. The liquid crystal panel adopting the pixel structure as described above is particularly advantageous for moving picture processing.

또한, 본 발명의 액정표시소자는 행반전구동방식과 프레임 분할구동방식을 병행하여 구동함으로써, 화상의 깜박거리는 현상을 방지할 수 있는 이점이 있다.In addition, the liquid crystal display of the present invention has an advantage of preventing the flickering of the image by driving the row inversion driving method and the frame division driving method in parallel.
