Abstract

The invention provides a drive circuit and a liquid crystal display panel. The drive circuit comprises a first drive unit and a second drive unit. The first drive unit contains a common voltage input terminal, a first common voltage output terminal, a second common voltage output terminal, a third common voltage output terminal, a first preliminary voltage output terminal and a second preliminary voltage output terminal; and the second drive unit consists of a first preliminary voltage input terminal, a second preliminary voltage input terminal, a fourth common voltage output terminal, a fifth common voltage output terminal, a sixth common voltage output terminal, and a seventh common voltage output terminal. In addition, the invention also provides a liquid crystal display panel. With the drive circuit and the liquid crystal display panel, adjustment of common voltages at different areas can be realized; and on the basis of no increase of the manufacturing cost, the image quality of the liquid crystal display panel is improved and the manufacturing period of the liquid crystal display panel is reduced.

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...
