摘要： A driver circuit for dot inversion of liquid crystals includes a positive source supplying a first positive signal and a second positive signal; a negative source supplying a first negative signal and a second negative signal; a first selector unit connected with the sources to receive the first positive signal and the first negative signal; a second selector unit connected with the sources to receive the second positive signal and the second negative signal; a first source connected with the selection unit to alternatively output a first positive voltage and a first negative voltage; a second source connected with the selection unit to alternatively output a second positive voltage and a second negative voltage. When the first source outputs the first positive voltage, the second source outputs the second negative voltage. When the first source outputs the first negative voltage, the second source outputs the second positive voltage.

摘要： The present invention relates to a driving circuit for a display panel, and comprises a switching module, a buffer circuit, and a plurality of resistive devices. The switching module is coupled to a first power supply and a second power supply. The voltage of the first power supply is smaller than that of the second power supply. The buffer circuit is coupled to the switching module, and is used for buffering a data signal and producing a buffer signal. The plurality of resistive devices is connected in series and coupled to the buffer circuit, and produces a plurality of driving signals between the plurality of resistive devices according to the buffer signal. The driving circuit switches between the first power supply and second power supply sequentially to supply power to the buffer circuit. Thereby, one of the plurality of driving signals charges a capacitor of the display panel for saving power of the driving circuit. Accordingly, the power of the display can be saved.

摘要： The present invention relates to a driving circuit for a display panel, which comprises a pre-charge power supply, a pre-charge switch, a buffer circuit, and a plurality of resistive devices. The pre-charge switch is coupled between the pre-charge power supply and a capacitor of the display panel. The buffer circuit is used for buffering a data signal and producing a buffer signal. The plurality of resistive devices is connected in series and coupled to the buffer circuit, and produces a plurality of driving signals therebetween according to the buffer signal. The driving circuit first closes the pre-charge switch to make the pre-charge power supply charge the capacitor. Then, one of the plurality of driving signals charges the capacitor. Thereby, the driving time can be shortened, and power of the display can be saved by avoiding power consumption on resistors.
