Abstract: A display device includes a data driver, a gate driver, a plurality of first pixel unit and a first low-pass filter. Each first pixel unit includes a first transistor, a first storage capacitor and a first liquid crystal capacitor. The first transistor is electrically coupled to the data driver and the gate driver and from which to receive the first display data and the gate control signal, respectively. The first transistor is configured to output the first display data according to the gate control signal. The first low-pass filter is configured to have its input electrode terminal electrically coupled to the second electrode terminal of one of the plurality of first transistor and its output electrode terminal electrically coupled to the second electrode terminal of the first liquid crystal capacitor of each of the first pixel units. An operation method for the display device is also provided.

Abstract: A booster circuit for liquid crystal pixel data includes first, second and third signal control switches and a first storage capacitor. The first signal control switch is ON through a driving of a first control pulse and electrically coupled to a data voltage. The second signal control switch is ON through a driving of the first control pulse and electrically coupled to a reference voltage. The third signal control switch is ON through a driving of a second control pulse and electrically coupled to the data voltage. The first storage capacitor includes two terminals. The first storage capacitor has its first terminal electrically coupled to the reference voltage through the second signal control switch and electrically coupled to the data voltage through the third signal control switch and its second terminal electrically coupled to the data voltage through the first signal control switch and for providing an output voltage.
