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： The present invention provides an apparatus for increasing the slew rate. The apparatus for increasing the slew rate comprises an operational amplifier and a push-pull output stage. The present invention is operated under the principle of when there is a big difference between the output signal and the input signal, either the pull-up transistor or the pull-down transistor in the push-pull output stage is ON, so that the pushed or pulled current is provided to a load on the output terminal. When the difference between the output signal and the input signal becomes smaller, the operation of the push-pull output stage stops, and the load on the output terminal is directly driven by the operational amplifier at this time. Since the present invention only deploys an operational amplifier and a push-pull output stage and does not deploy error amplifier, the present invention reduces occupied area and saves consumed power, and also avoids offset voltage and oscillation problems.
