Abstract
A driving circuit applied to a LCD apparatus is disclosed. The driving circuit includes a channel data line, a reference voltage generation unit, an external storage capacitor, a comparing unit, a switching unit, and an operation unit. The channel data line transmits a data. The reference voltage generation unit generates a reference voltage. A terminal of the external storage capacitor is coupled to ground. The comparing unit compares the reference voltage and a capacitor voltage and outputs a compared result. The switching unit is coupled to another terminal of the external storage capacitor and the channel data line. The operation unit is coupled to the comparing unit, the channel data line, and the switching unit to receive the compared result and a MSB of the data to operate, and to selectively switch on the switching unit.
