Abstract: A display driving device is provided. The display device includes a first data line, a first switch, a first storage unit, and a data output unit. The first switch is electrically connected between the first data line and the data output unit, and the data output unit is further electrically connected to the first storage unit. In a first closing period of the first switch, the data output unit outputs a first data signal to the first data line through the first switch, and the first storage unit stores the first data signal received from the data output unit. After the first closing period and before a second closing period of the first switch, the first storage unit charges the data output unit with the first data signal so that the data output unit and the first data line are at the voltage level.
