Abstract

A driving circuit of a flat panel display device includes a horizontal bus, a plurality of horizontal driver ICs, a vertical bus, and a plurality of vertical driver ICs. The horizontal driver IC is operative to decode N-types of vertical driving signals output from the horizontal bus, so as to transmit the N-type vertical driving signals to the corresponding vertical driver IC via a vertical signal line of the vertical bus.
