摘要： A power-saving device for a driving circuit of a liquid crystal display panel is provided. The device comprises a first switch, a first capacitor, a second switch, a second capacitor, a third switch, an output buffer and a common electrode or a data line. The first capacitor and the second capacitor are coupled to the common electrode or the data line through the first switch and the second switch respectively. The output buffer is coupled to the common electrode or the data line through the third switch. The output buffer charges or discharges a ground-referenced equivalent capacitor of the data line or the common electrode. The device uses the switches to conduct positive and negative electric charges to the capacitors so that charges produced during the charging and discharging in the driving circuits of the common electrodes and data line can be stored and recycled to avoid unnecessary power waste.

摘要： A source driver for an LCD panel includes two gm stages and two output buffers. In a normal operation mode, the first gm stage and the first output buffer establish a unity gain buffer to amplify a positive polarity analog voltage to be a positive polarity output voltage, and the second gm stage and the second output buffer establish a unity gain buffer to amplify a negative polarity analog voltage to be a negative polarity output voltage. In a polarity inversion mode, the second gm stage and the first output buffer establish a unity gain buffer to amplify a positive polarity analog voltage to be a positive polarity output voltage, and the first gm stage and the second output buffer establish a unity gain buffer to amplify a negative polarity analog voltage to be a negative polarity output voltage.
