Abstract
Disclosed are a display device, a display driving circuit thereof, and an operating method thereof. The display device includes a power management circuit and a display driving circuit. The display driving circuit converts a power voltage provided by the power management circuit into a first boundary voltage and a second boundary voltage, and generates multiple gamma voltages based on the first boundary voltage and the second boundary voltage. When a system condition transitions from a normal state to a specified state, the first boundary voltage transitions to a specified boundary level, and the power voltage transitions to a specified power level. When the system condition returns from the specified state to the normal state, the first boundary voltage returns to a normal boundary level, and the power voltage returns to a normal power level.
