  • Display driving device and display device including the same
    Patent number: 10497302
    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.
