Abstract:
1. A driving circuit of a flat panel display, comprising: a first data signal processing unit for converting a first display information that will be displayed on the flat panel display into a positive gamma value; a second data signal processing unit for converting a second display information that will be displayed on the flat panel display into a negative gamma value; a first signal amplifying unit for amplifying the positive gamma value from the first data signal processing unit to output the amplified positive gamma value to a switch unit; and a second signal amplifying unit for amplifying the negative gamma value from the second data signal processing unit to output the amplified negative gamma value to the switch unit; wherein the switch unit for selectively transferring the amplified positive and negative gamma values to an output driving unit; the output driving unit for outputting the amplified negative and positive gamma values to the flat panel display; the output driving unit enhances driving capability of a signal passing through the switching unit and transmits the signal directly to a flat display; the switch unit comprises a feedback switch unit for feedback of an output of the output driver unit as an input of one of the first signal amplifying unit and the second signal amplifying unit; the first data signal processing unit and the second data signal processing unit control two channels of the flat panel display; the output driving unit includes: the switch unit includes:
