Abstract:
A driver circuit for LCDM (liquid crystal display module) that is installed with a plurality of lamps to be driven within a work period, the driver circuit comprising:a driving unit, which receives the work period, performs operations on the work period and, after the operations being completed, sends a plurality of driving voltages in an asynchronous way to an output terminal within the work period; and a transformer unit, which is connected to the driving unit for receiving, amplifying and transforming the plurality of driving voltages and transmitting them to the plurality of lamps, wherein the driving unit further comprises: a driving unit, which receives the work period, performs operations on the work period, and, after the operations being completed, produces a plurality of driving signals in an asynchronous way to a first output terminal and a second output terminal; a first switching unit, which is connected to the first output terminal for converting the driving signal into the driving voltage to be sent to the first output terminal; and a second switching unit, which is connected to the second output terminal for converting the driving signal into the driving voltage to be sent to the second output terminal.
