Display, display driving device, and driving method thereof

A display driving method applicable to a driving device connected to a first data line of a display panel, the driving device including a first switch electrically connected to the first data line, a first storage unit, and a data output unit electrically connected to the first switch and the first storage unit, the display driving method comprising the following steps:

• a. when the first switch is in the first closing period, outputting, by the data output unit, the first data signal to the first data line through the first switch, and outputting the first data signal to the first storage unit;
• and
• b. when the first switch is in the second closing period, outputting, by the data output unit, a third data signal to the first data line through the first switch, and outputting the third data signal to the first storage unit;
• wherein before step b, 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 same voltage level.

A display, comprising:

• a data driver having an output pin for outputting a data signal;
• a plurality of data lines;
• a multiplexing unit including a plurality of first switches, each of the first switches having a first input end, a first output end, and a first control end, the first output end being connected to one of the data lines, and each of the first switches electrically connecting the first input end and the first output end when the first control terminal receives a selection signal;
• a data output unit electrically connected between the first input ends of the multiplexing unit and the data driver, the data output unit outputting, the data signal from the data driver to the multiplexing unit, and the data signal being outputted to the data line through the closed first switch of the multiplexing unit;
• a plurality of storage units electrically connected to the data output unit, each of the storage units being connected to one of the first switches, and each of the storage units including:
• a second switch, including a second input end, a second output end, and a second control end, the second input end being electrically connected to the data output unit and the first input end of the first switch to which the storage unit is connected, the second control end and the first control end of the first switch receiving the selection signal simultaneously, and electrically connecting the second input end and the second output end;
• a third switch, including a third input end, a third output end, and a third control end, the third input end being electrically connected to the second output end, the third output end being electrically connected to the data output unit, and the third control end electrically connecting the third input end and the third output end according to a horizontal enable signal;
• and
• a capacitor electrically connected to the second output end and the third input end, the capacitor storing the data signal when the second switch is closed, and outputting the data signal to the data output unit when the third switch is closed.
