Active matrix display device and method therefor

A method for driving an active matrix device comprising gate lines arranged in rows, a plurality of signal lines arranged in columns, and pixels arranged at the crossing parts between said gate lines and signal lines, comprising the following steps of:

• line scanning in sequence of each of the gate lines and selecting pixels for at least one row;
• sampling in sequence the video signals and writing the video signals by dot sequential scanning to the pixels in one selected row;
• and
• sequentially providing a precharging signal to each of the signal lines in sequence prior to a sequential sampling of the video signal for each of the signal lines.

An active matrix display device operatively connected with a source of video signal, and a source of precharge voltage, comprising:

• a plurality of gate lines arranged in rows;
• a plurality of signal lines arranged in columns;
• a matrix of pixels wherein each pixel is operatively interconnected with a gate line and a signal line;
• a vertical scanning circuit for scanning the gate lines;
• a horizontal scanning circuit for scanning the signal lines and for sequentially writing the video signal to one signal line at time so as to perform, in combination with the vertical scanning, a dot sequential scanning of the pixels;
• and
• switch means for sequentially selecting and supplying the precharging voltage to one signal line at a time and in a manner wherein the signal line, to which the precharge voltage is supplied, is immediately adjacent a signal line to which the video signal is being written.
