Method and apparatus for driving active matrix display panel, and display

摘要

A method and apparatus for driving an active matrix display panel includes a plurality of scanning lines, a plurality of data lies intersecting the scanning lines, and a plurality of pixel electrodes that are coupled to the scanning lines and the data lines. The method includes activating the scanning lines sequentially, and adjusting common voltages applied to a plurality of common electrodes that are disposed opposite to the pixel electrodes in response to differences in voltage changes generated among the pixel electrodes when the scanning lines changes from an on state to an off state. Therefore a voltage difference between each of the pixel electrodes and a common electrode arranged opposite to the pixel electrode is equal to a target voltage.

1. A method for driving an active matrix display panel, the active matrix display panel comprising a scanning line driving circuit having a plurality of scanning lines, a plurality of data lines intersecting with the plurality of scanning lines, a plurality of pixel electrodes provided in regions surrounded by adjacent scanning lines and adjacent data lines, each of the pixel electrodes being capacitively coupled to one of the scanning lines and to one of the data lines through an electronic switch, and a common electrode driving circuit configured to drive a plurality of common electrodes arranged opposite to the pixel electrodes; the method comprising:
turning on the scanning lines sequentially, the scanning lines comprising a plurality of first scanning lines having a first resistance and a plurality of second scanning lines, wherein the first scanning lines and the second scanning lines are manufactured with different materials; and adjusting common voltages applied to the common electrodes in response to differences between a first feed-through voltage of the first scanning line and a second feed-through voltage of the second scanning line, so that a voltage difference between each of the pixel electrodes and a common electrode is substantially equal to a target voltage, wherein the first feed-through voltage is a changed voltage generated when the first scanning line changes from an on state to an off state; the second feed-through voltage is a changed voltage generated when the second scanning line changes from an on state to an off state.
