Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a method for accelerating the rotation of liquid crystal molecules and a liquid crystal panel driving circuit used in the method. Background technique [0002] A liquid crystal display is a display device that includes two glass substrates disposed relatively in parallel and liquid crystal molecules disposed between the two substrates, and uses electrical excitation to perform optical switching by using photoelectric anisotropy of the liquid crystal molecules. Utilizing that liquid crystal molecules have refractive index anisotropy, the brightness of light transmitted by the liquid crystal molecules is controlled by applying a voltage to the liquid crystal molecules and thereby reorienting the axis of the refractive index anisotropy. [0003] The liquid crystal material of VA liquid crystal display is mainly liquid crystal molecules with negative dielectric anisotropy. When...
