Problems solved by technology

Although the traditional dark-state black insertion technology can improve the hysteresis problem of blue-phase liquid crystals, thereby improving the contrast and transmittance of the display device, but for the dark-state light leakage (dark-state light leakage) of the blue-phase liquid crystal display device, The traditional dark-state black insertion technology still cannot be effectively improved, resulting in unstable dark-state transmittance of blue-phase liquid crystal display devices and seriously affecting its contrast.

Abstract

A drive method for a blue phase liquid crystal display device matches with a blue phase liquid crystal display device. The liquid crystal display device comprises at least a data line, at least a scanning line and at least a pixel. The drive method for the blue phase liquid crystal display device comprises the following steps of transmitting first grave scale voltage to the pixel through the data line; transmitting first recovery voltage to the pixel through the data line; transmitting a first insertion black voltage to the pixel through the data line and the absolute value of the first recovery voltage is higher than that of the first grove scale voltage and the first insertion black voltage. The drive method for the blue phase liquid crystal display device has the advantages of solving the problems of dark state light leak of the blue phase liquid crystal display device.

Description

technical field [0001] The invention relates to a driving method of a display device, in particular to a driving method of a blue phase liquid crystal display device. Background technique [0002] The blue phase liquid crystal is a self-aggregated three-dimensional photonic crystal structure, and the liquid crystal phase appears between the isotropic phase and the cholesterol phase. In addition, the blue-phase liquid crystal has self-assembled three-dimensional lattice characteristics, but retains the nature of fluid, and its lattice parameters are easy to change, and can have different optoelectronic properties. It is an excellent adjustable photonic crystal, so it can be applied to three-dimensional display device. Among them, compared with the traditional liquid crystal display technology, the blue phase liquid crystal display device has the advantages of fast response time and wide viewing angle, and does not need an alignment film, so it has received extensive attentio...
