Driving method of light emitting diode

Abstract

A power-saving and efficient driving method for driving a matrix of a plurality of light emitting diodes arrayed in rows and columns, for enabling each row and column being driven with respect to the state thereof while each row being in a state selected from the group consisting of active and non-active and each column being in a state selected from the group consisting of active and non-active, the method comprising the steps of: (A) executing the phases of Dis-Charge, Pre-Charge, Current On and Dis-Charge in successive for an active column; (B) executing the phases of Dis-Charge, Floating, Dis-Charge and Dis-Charge in successive for a non-active column; (C) executing the phases of Current Sink, Current Sink, Current Sink and Current Sink in successive for an active row; and (D) executing the phases of Floating, Floating, Reverse Bias and Floating in successive for a non-active row.
