  • Patent number: 12140839
    Abstract: The present application discloses a liquid crystal alignment method, a liquid crystal display panel, and a mobile terminal. In a liquid crystal alignment process, an external electrode receives an alignment voltage, and a pretilt angle of a liquid crystal molecule corresponding to a branch electrode is smaller than a pretilt angle of a liquid crystal molecule corresponding to a slit. In an actual driving process, because an overall pretilt angle of liquid crystal molecules is increased and pretilt angles in a same domain of a subpixel are differentiated, a response time and view angle features of medium and low grayscale of the liquid crystal display panel can be improved.
