Abstract
A driving device and a liquid crystal display device are disclosed. In the driving device, a charging efficiency difference between a positive polarity voltage and a negative polarity voltage on a pixel can be compensated through increasing a duration of a gate driving signal, shortening a time period during which the positive polarity voltage is provided to a source line, and prolonging a time period during which the negative polarity voltage is provided to the source line. In this manner, the technical problem of non-uniform brightness of an image displayed in a traditional liquid crystal display panel and unsatisfactory display effect thereof can be solved.
