Abstract: A display driving device includes a power circuit, a gate driver, a data driver, and a controller. The power circuit generates gate supply voltages. The gate driver applies a gate driving signal to gate lines. The data driver applies data signals to data lines intersecting the gate lines. The controller controls the power circuit, the gate driver, and the data driver to set the gate driving signal to be at least one of the gate supply voltages when abnormal power off occurs. The controller also controls the power circuit to allow the gate supply voltages to be discharged naturally.

Abstract: A display driver integrated circuit (IC) and a display system including the same are provided. The display driver IC includes: a charge pump including a first node and a second node; a flying capacitor connected between the first node and the second node; a voltage regulator; a first switch connected between an output terminal of the voltage regulator and one of the first node and the second node; and a second switch connected between a ground and the other of the first node and the second node.
