| 摘要 |
The present invention relates to a display driving circuit and a display driving system, and more particularly, to a display driving circuit having a half-VDD power supply circuit built therein and a display driving system including the same, in which the display driving circuit is further provided with a half voltage VDD terminal in addition to the highest voltage VDD terminal and the lowest voltage VSS terminal, and the half voltage, which is between the highest voltage and the lowest voltage, is generated and supplied by the half voltage power supply from the inside of the display driving circuit, rather than being supplied from an external power supply.
