Abstract
The present disclosure relates to a liquid crystal display, a display panel and a reference voltage control method of a display panel and a reference voltage control device for a display panel. The reference voltage control method of a display panel includes acquiring a refreshing frequency of the display panel; invoking a reference voltage database according to the refreshing frequency, to acquire reference voltage data corresponding to the refreshing frequency; generating a reference voltage adjusting signal for adjusting a reference voltage signal fixedly output by the display panel according to the reference voltage data; and synthesizing the reference voltage adjusting signal and the reference voltage signal fixedly output by the display panel to generate a reference voltage synthesis signal, and outputting the reference voltage synthesis signal to a reference voltage signal input terminal of the display panel.
