Abstract
A scan circuit applicable to driving a plurality of light-emitting-diodes of a display panel is provided. Each of a plurality of switching components is electrically connected with a scan line of the display panel for determining if the light-emitting-diodes connected to the scan line are conductive. A plurality of power transistors are disposed corresponding to the scan lines, each connected between one scan line and a ground terminal. A low-dropout regulator circuit or global operational amplifier is alternatively connected to the plurality of switching components in common for selectively pulling up a voltage level of the scan lines and avoiding ghost imaging on the display panel. By employing the proposed scan circuit, the invention is effective in achieving de-ghost functioning and avoiding conventional signal coupling issues on the display panel. In addition, redundant power waste consumption is significantly reduced at the same time.
