  • Patent number: 9919486
    Abstract: A method of manufacturing a light refection film includes: preparing a precursor, the precursor includes white pigments and liquid UV (ultraviolet) curing material. The white pigments are evenly dispersed in the UV curing material, and a weight ratio of the white pigments and the UV curing material ranges from 20:80 to 38:62. Then the following step is providing a first base, and arranging a blocking part on the first base to limit a receiving area of the precursor. The precursor is thereafter dropped into the receiving area of the precursor. A second base is then brought to press the precursor, the precursor is cured by exposure UV to form the light reflection film, finally the first base, the second base, and the blocking part are removed to obtain the light reflection film. The present disclosure also provides a light reflection film obtained by the method.
