Abstract
An optical film includes a polarizer. The polarizer includes a base layer, and a material of the base layer is obtained by dyeing a base material with a dye. The base material includes a polyvinyl alcohol material, and the dye is selected from blue dichroism organic dyes.
Claims20
An optical film, the optical film being applied to a reflective liquid crystal display panel including a liquid crystal cell, and the optical film comprising:
- a phase compensation film;
- and
- a polarizer, the polarizer including a base layer, a material of the base layer being obtained by dyeing a base material with a dye;
- a color of the dye corresponding to values of a* and b* of the polarizer in a CIE1976 L*a*b* chromaticity space, and the values of a* and b* of the polarizer in the CIE1976 L*a*b* chromaticity space being obtained according to target values of a* and b* of a white picture displayed by the reflective liquid crystal display panel in the CIE1976 L*a*b* chromaticity space and reference values of a combination of the reflective liquid crystal display panel including the phase compensation film and the liquid crystal cell except for the polarizer in the CIE1976 L*a*b* chromaticity space;
- wherein the base material includes a polyvinyl alcohol material, and the dye is selected from blue dichroic organic dyes.
A method of manufacturing an optical film, wherein the optical film is applied to a reflective liquid crystal display panel including a liquid crystal cell and includes a phase compensation film and a polarizer;
- the method comprises:
- obtaining values of a* and b* of the polarizer in a CIE1976 L*a*b* chromaticity space, according to target values of a* and b* of a white picture displayed by the reflective liquid crystal display panel in the CIE1976 L*a*b* chromaticity space and reference values of a combination of the reflective liquid crystal display panel including the phase compensation film and the liquid crystal cell except for the polarizer in the CIE1976 L*a*b* chromaticity space;
- and
- dyeing a base material with a dye corresponding to the values of a* and b* of the polarizer to be formed in the CIE1976 L*a*b* chromaticity space to form the polarizer.
