A shift register is provided, which adopts a shift operation delay for each memory device, or a data conversion control system through the estimation of conversion of data storage state. A driver circuit of LCD is provided, which adopts such a shift register, to thereby prevent instantaneous increase of electric power consumption while preventing EMI. Accordingly, shift registers operate as being sequentially delayed for each memory device or data conversion is minimized, thus preventing instantaneous excessive consumption of electric power.

Shift register and driving circuit of LCD using the same

Disclosed is a flat panel display device which comprises a power supply unit provided on a first PCB and supplying the power; an image driver provided on a second PCB and controlling predetermined images to be displayed; and a signal processor provided on a third PCB, connected to the image driver via a differential signal interface, converting the image signals provided from the outside into a format of signals that fits the flat panel display panel, and providing the converted signals to the image driver. The present invention reduces the EMI.
