Abstract

The invention discloses a liquid crystal display panel capable of switching the viewing angle and a drive method of the liquid crystal display panel. A pixel unit of a liquid crystal display panel display region comprises a primary pixel region and a secondary pixel region; the primary pixel region is homogeneous alignment and arranged in the primary pixel region, and a lower substrate is provided with pixel electrodes and public electrodes at intervals; the secondary pixel region is homeotropic alignment and arranged in the secondary pixel region, and an upper substrate and the lower substrate are correspondingly provided with an upper substrate electrode and a pixel electrode respectively. When no bias voltage is applied on the upper substrate electrode of the secondary pixel region, the liquid crystal molecules corresponding to the secondary pixel region do not defect, and the large viewing angle of the secondary pixel region leaks light, narrow viewing angle display is achieved; when the bias voltage is applied on the upper substrate electrode of the secondary pixel, the liquid crystal molecules corresponding to the secondary pixel region deflect to the plane-on state, the large viewing angle of the secondary pixel region does not leak the light any more, and wide-view-angle display is achieved.

Description

Technical field [0001] The present invention relates to liquid crystal display technology, in particular to a liquid crystal display panel with a switchable viewing angle and a driving method thereof. Background technique [0002] The viewing angle range (referred to as viewing angle) is an important performance index of the liquid crystal display panel. The liquid crystal display panel needs to change the polarization state of the transmitted light by adjusting the arrangement of the liquid crystal molecules to realize the display function. Therefore, due to the influence of the optical anisotropy of the liquid crystal molecules, the viewing angle of the liquid crystal display is smaller than that of the cathode ray tube display. With the continuous development of technology, in order to increase the viewing angle of liquid crystal displays, vertical alignment (VA) mode, pattern vertical alignment (PVA) mode, multi-chip vertical alignment (MVA) mode, in-plane switching (IPS) mo...
