그 구성은 액티브 매트릭스 표시장치는 행형태로 배선한 복수의 게이트라인 (X)과, 열형태로 배선한 복수의 데이터라인(Y)과, 양자의 각 교차부에 설치된 복수의 화소(PXL)를 가지고 있다. 행렬로 배치한 화소(PXL)는 표시영역(1)을 구성한다. 수직주사회로(2)는 각 게이트라인(X)을 순차 수직주사하고, 일수평기간마다 일행부의 화소(PXL)를 선택한다. 수평주사회로(3)는 일수평기간내에 각 데이터라인(Y)을 순차 주사하고 영상신호(Vsig)를 샘플링하여 선택된 일행분의 화소(PXL)에 점순차로 영상신호(Vsig)를 기입한다. 데이터라인(Y)은 표시영역(1)내에 배선된 실데이터라인(Y1,Y2,…,YL)과, 표시영역(1)외에 배치되어 게이트라인(X)의 종단부와 교차하는 더미데이터라인(YD1,YD2,YD3,YD4)으로 구분되어 있다. 수평주사회로(3)는 실데이터라인(Y1,Y2,…,YL)에 대하여 복수개의 걸쳐서 오버랩한 샘플링타이밍에서 수평주사를 행하고 다시 연속하여 더미데이터라인(YD1,YD2,YD3,YD4)에 대하여도 오버랩한 샘플링타이밍에서 수평주사를 계속한다.The structure of the active matrix display device includes a plurality of gate lines X wired in a row, a plurality of data lines Y wired in a column, and a plurality of pixels PXL provided at respective intersections thereof. Have. The pixels PXL arranged in a matrix constitute the display area 1. The vertical scanning furnace 2 sequentially scans each gate line X, and selects the pixels PXL of one row at every horizontal period. The horizontal scanning furnace 3 sequentially scans each data line Y within one horizontal period, samples the image signal Vsig, and writes the image signal Vsig in the dot sequence to the selected pixel PXL. . The data line Y is a real data line Y1, Y2, ..., YL wired in the display area 1, and a dummy data line disposed outside the display area 1 and intersecting with an end of the gate line X. (YD1, YD2, YD3, YD4). The horizontal scanning furnace 3 performs horizontal scanning at a plurality of overlapping sampling timings with respect to the actual data lines Y1, Y2, ..., YL, and then successively performs dummy scanning on the dummy data lines YD1, YD2, YD3, and YD4. Also, horizontal scanning is continued at the overlapping sampling timing.
