Abstract: A power management circuit includes a regulator circuit, a first frequency compensation circuit, a first switch circuit and a detection circuit. The regulator circuit includes a signal output end. The first switch circuit is turned on in response to an enabled first control signal such that the first frequency compensation circuit is coupled to the regulator circuit. The detection circuit determines whether an output capacitor is coupled to the signal output end, and generates the enabled first control signal to turn on the first switch circuit and connect the first frequency compensation circuit to the regulator circuit when the output capacitor is not coupled to the signal output end. Therefore, the regulator circuit is frequency compensated by the first frequency compensation circuit.

Abstract: A low power driving method for a display panel and a driving circuit therefor. When the voltage of a corresponding common electrode of a pixel in a pixel array is changed from one of the first voltage and the second voltage to the other thereof according to a polarity signal, the voltage of the corresponding pixel electrode of the pixel is driven. In an embodiment, a data code for the pixel and the polarity signal are utilized to predict a trend of the corresponding target voltage of the data code, and the voltage of the pixel electrode or the data line is changed to a voltage close to the target voltage of the pixel according to the prediction result. Thus, the swing range of the voltage of the data line can be efficiently reduced, and power saving and reduction in transition time can also be achieved.

Abstract: A TFT-LCD capable of repairing discontinuous lines includes a repairing circuit, which includes a plurality of repairing OP amplifiers and a high-impedance detecting unit. The high-impedance detecting unit detects states of input terminals of the OP amplifiers. The high-impedance detecting unit enables a control signal to enable the OP amplifier when the input terminal is not at floating state. The high-impedance detecting unit disables the control signal to disable the OP amplifier when the input terminal is at floating state, so that no output competition between the OP amplifiers is generated.
