Abstract:
An active-matrix display device, comprising:a plurality of rows of gate lines; a plurality of columns of signal lines for applying video signals corresponding at least to a black signal level and a white signal level depending on an image to be displayed; a matrix of pixels provided in the region where said gate lines and said signal lines intersect; a vertical scanning circuit for sequentially scanning said gate lines in one vertical period, and selecting one row of pixels every horizontal period; a horizontal scanning circuit for sampling the video signal for each signal line before writing the video signal in the selected one row of pixels; and a voltage applying circuit for applying to each signal line a voltage equal to or less than the minimum level of the video signal corresponding to the black signal level in a horizontal period excluding a time assigned for writing the video signal in one row of pixels during that same horizontal period.
