Claim Text:
1. A driver integrated circuit (IC) of a display apparatus that generates a logic voltage in a power environment in which an analog voltage and a logic input/output (JO) voltage are irregularly inputted to the driver IC, the driver IC comprising: a first power generating unit that generates a first reference current and a first reference voltage based on the analog voltage; a second power generating unit that generates a second reference current and a second reference voltage based on the logic I/O voltage; and a logic voltage generating unit that generates a logic voltage in response to the first reference current and voltage or the second reference current and voltage according to an application order of the analog voltage and the logic I/O voltage in the power environment in which the analog voltage and the logic I/O voltage are irregularly inputted to the driver IC.
