Abstract
A boosting voltage generator includes a switching circuit, a control circuit and a boosting circuit. The switching circuit is connected to a first input terminal receiving a first frame signal and a second input terminal receiving a second frame signal, and generates a first switching signal and a second switching signal based on a voltage at the first input terminal and a voltage at the second input terminal. The second frame signal has a phase opposite to that of the first frame signal. The control circuit is connected to the first and second input terminals, and selectively connects the first and second input terminals with a ground voltage based on a mode selection signal. The boosting circuit generates a first boosting voltage and a second boosting voltage based on the first switching signal, the second switching signal, a first feedback voltage and a second feedback voltage.
