Beschreibung
Zusammenfassung:	The invention provides a compensating circuit for improving liquid crystal capacitor frequency responses. The circuit comprises a first switch, a second switch, a liquid crystal capacitor, a first storage capacitor, a second storage capacitor, a third switch, a fourth switch, a first compensating capacitor and a second compensating capacitor. The first ends of the first switch and the second switch are coupled to a first data line and a second data line respectively, and the control ends are coupled to a same scanning line. The liquid crystal capacitor is arranged between the second end of the first switch and the second end of the second switch. The first ends of the third switch and the fourth switch are coupled to third and fourth public electrode lines respectively. The first compensating capacitor is in cross connection between the second end of the first switch and the second end of the third switch. The second compensating capacitor is in cross connection between the second end of the second switch and the second end of the fourth switch. Compared with the prior art, the two compensating capacitors are arranged, so that when the first switch and the second switch are off, the compensating capacitors storing charging charges can compensate end voltages and potential of liquid crystal capacitors, and accordingly, output signals are prevented from becoming small.
