Abstract:
1. A driving circuit for a display device comprising: a DC-DC converter provided inside one chip, for converting an external voltage input depending on a timing control signal and providing a controlled DC voltage; an interface unit provided inside the chip, for interface with parts outside the chip; a memory provided inside the chip, for storing display information transmitted through the interface unit; a data processor provided inside the chip, for providing a display data to a display panel of the display device using the display information stored in the memory and the controlled DC voltage output from the DC-DC converter; a scan processor provided inside the chip, for outputting scan data to the display panel using the display information and the controlled DC voltage output from the DC-DC converter; a timing control unit provided inside the chip, for providing the timing control signal to the DC-DC converter, the interface unit, the memory, the data processor, and the scan processor; and a power peripheral unit provided outside the chip, for controlling input and output voltages of the DC-DC converter, preventing a backward current from occurring during the DC-DC conversion, and maintaining the input DC voltage for a predetermined time, wherein the power peripheral unit comprises:
