Method and device for termination detection of optical alignment of liquid crystal material

A device for termination detection of optical alignment of liquid crystal material, which at least comprises:

• an electrical field device for generating an electrical field;
• an irradiation device for irradiating light so as to cause reactive monomers in a liquid crystal material to polymerize under the influence of electrical field and the irradiating light to realize optical alignment of liquid crystal material;
• a first detection device for detecting a residual amount of reactive monomers in the liquid crystal material;
• and
• a first determination device for determining whether the detected residual amount of reactive monomers in the liquid crystal material reaching a default value;
• wherein when the first determination device determining the default value being reached, terminating the optical alignment on the liquid crystal material.
