Abstract:
The present invention provides a gamma voltage supply circuit capable of stably supplying a gamma voltage in response to the change of external voltage and a power management IC including the same. The gamma voltage supply circuit generates a regulating voltage using an internal voltage which is not influenced by the variation in load of a source driver IC, and generates a gamma voltage using the regulating voltage.
