Abstract

The invention discloses a pixel driving circuit and a liquid crystal display panel. The pixel driving circuit comprises a main pixel electrode driving module, a secondary pixel electrode driving module, a first potential adjusting module and a second potential adjusting module. According to the pixel driving circuit and the liquid crystal display panel provided by the invention, the potential of a main area pixel electrode module is adjusted by arranging the first potential adjusting module, and the potential of a secondary area pixel electrode module is adjusted by arranging the second potential adjusting module; namely, the potential of the main area pixel electrode driving module and the potential of the secondary area pixel electrode driving module are adjusted at the same time, so that the view angle adjusting range is enlarged, and the large-view-angle color cast is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a pixel driving circuit and a liquid crystal display panel. Background technique [0002] In vertically aligned liquid crystal display panels, due to the large difference in birefringence of liquid crystals under different viewing angle conditions, the problem of large viewing angle deviation is serious. The most commonly used method to improve this problem is the 8-domain display technology, that is, the pixels are divided into main area pixels and sub area pixels, and the liquid crystal inversion degree of the main area pixels and sub area pixels is different to improve the problem of large viewing angle deviation. [0003] However, the liquid crystal display panel adopting the 8-domain display technology only achieves different liquid crystal inversion degrees between the pixels in the main area and the pixels in the sub area through the leakage design of the pixels...
