Abstract

The present invention provides a driving circuit and a liquid crystal display panel. The driving circuit includes a first driving unit and a second driving unit. The first driving unit includes a common voltage input terminal, a first common voltage output terminal, a second common voltage output terminal, The third common voltage output terminal, the first preliminary voltage output terminal and the second preliminary voltage output terminal; the second drive unit includes the first preliminary voltage input terminal, the second preliminary voltage input terminal, the fourth common voltage output terminal, the fifth common The voltage output terminal, the sixth common voltage output terminal and the seventh common voltage output terminal. The present invention also provides a liquid crystal display panel. The driving circuit and the liquid crystal display panel of the present invention can realize the adjustment of common voltages in different regions, without increasing the production cost, improve the picture quality of the liquid crystal display panel, shorten the Panel production cycle.

Description

technical field [0001] The invention relates to the field of display driving, in particular to a driving circuit and a liquid crystal display panel. Background technique [0002] With the development of technology, more and more users use liquid crystal display devices, and at the same time, the display quality requirements of liquid crystal display devices are also getting higher and higher. [0003] Liquid crystal molecules are arranged in the liquid crystal display panel of the liquid crystal display device, and the liquid crystal molecules are deflected at different angles under the action of the pixel voltage and the common voltage, thereby presenting different gray scales. In order to facilitate the control of the deflection angle of the liquid crystal molecules, the common voltage is generally stable, so that the display screen of the liquid crystal display device can be controlled only by adjusting the magnitude of the pixel voltage. [0004] As the size of the liqu...
