Abstract

A driver circuit of an LCDM is disclosed. The driver circuit contains a driving unit and a transformer unit. When the LCDM needs to drive a plurality of inverters, the driving unit sends out a driving voltage in an asynchronous way to drive the transformer unit. The transformer unit amplifies the driving voltage and sends it to the lamps. The invention thus achieves the goal of driving the LCDM using different timings within a work period.
