摘要：

The invention provides a driving circuit applied in a LCD apparatus. The driving circuit includes N first channels, N second channels, 2N first switching units, and 2N second switching units. N is a positive integer and N≧2. N second channels correspond to N first channels. When the driving circuit is operated under a first operation mode, N first switching units in the N first channels switch to connect with the corresponding N second channels, and the other N first switching units in the N second channels switch to connect with the corresponding N first channels according to a control signal respectively. N second switching units in the N first channels switch to connect with the corresponding N second channels, and the other N second switching units in the N second channels switch to connect with the corresponding N first channels according to a control signal respectively.
