Abstract:
1. An electronic device for enhancing image quality of a liquid crystal display (LCD) monitor comprising: a first reception end, for receiving a start indication signal utilized for indicating an operation state of a scan line signal output circuit of the LCD monitor; a second reception end, for receiving an output indication signal utilized for controlling an output state of the scan line signal output circuit; a third reception end, for receiving a residue power of the LCD monitor; an output end, coupled to the scan line signal output circuit; and a logical unit, coupled to the first reception end, the second reception end, the third reception end and the output end, for comparing a level of an output indication signal and a level of the residue power when the start indication signal indicates that the scan line signal output circuit changes from an ON state to an OFF state, to output a comparison result to the scan line signal output circuit, so as to prolong time of the scan line signal output circuit driving a panel of the LCD monitor.
