Abstract
A driving circuit for liquid crystal panels and the liquid crystal devices are disclosed. The driving circuit includes a source driver, and at least one selection circuit. A number of the selection circuit is the same with the number of rows of the sub-pixel cells. Each of buffer data output ends of the source driver respectively connect to an input end of one selection circuit. A first output end of each of the selection circuit connects to the sub-pixel cells in one row. A second output end of each of the selection circuit connects to the sub-pixel cells in another row. The sub-pixel cells connecting with the first input end are within the same pixel row combination having the same color. In this way, the power consumption of the source driver of the driving circuit is reduced.
