Abstract
A driver integrated circuit of a display apparatus generates a logic voltage in a power environment in which an analog voltage and a logic input/output voltage are irregularly inputted to the driver integrated circuit. The driver integrated circuit includes 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 input/output 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 input/output voltage.
