1. one kind is used for the electronic installation that a LCD promotes picture quality, includes:

  • One first receiving end is used for receiving a start indicator signal of this LCD, and this start indicator signal is used to refer to the mode of operation of the one scan line signal output apparatus of this LCD;

    One second receiving end is used for receiving one of this LCD and exports indicator signal, and this output indicator signal is used for controlling the output situation of this scanning-line signal output circuit;

    One the 3rd receiving end is used for receiving a remaining power supply in this LCD;

    One output terminal is coupled to this scanning-line signal output circuit;

    AndOne logical block, be coupled to this first receiving end, this second receiving end, the 3rd receiving end and this output terminal, be used for when this start indicator signal indicates this scanning-line signal output circuit to be converted to an off-mode by an open state, relatively should export the level of indicator signal and the level of this remnants power supply, exporting a comparative result, thereby prolong the time that this scanning-line signal output circuit drives a panel of this LCD to this scanning-line signal output circuit.
