ABSTRACT:
An analog buffer includes a comparator unit for comparing an input signal to be charged on a signal line of a display panel with an output signal charged on the signal line of the display panel to output a control signal; and a current switching unit for discharging an output current from the signal line of the display panel or charging an input current on the signal line of the display panel in accordance with the control signal output by the comparator unit the comparator unit smallest and to thus minimize leakage current.
