Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a multi-angle controllable liquid crystal display device and a driving method. Background technique [0002] Liquid crystal display (liquid crystal diPlay, LCD) has the advantages of good picture quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and it occupies a dominant position in the field of flat panel display. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. Therefore, in addition to the wide viewing angle, the display devi...
