Abstract

The application provides a preparation method of an optical film, the optical film, and a display panel. The preparation method of the optical film comprises the following steps of placing a pluralityof graphene sheets prepared in advance in a mixed solution to form an anti-reflection mixed solution; coating the anti-reflective mixed solution on a substrate; orienting the anti-reflective mixed solution by a magnetic field to deflect the plurality of graphene sheets in the anti-reflective mixed solution to a predetermined angle; and curing the anti-reflective mixed solution to form an anti-reflective layer on the substrate. In the application, by forming an anti-reflective layer having graphene sheets on the substrate, the graphene sheets can reduce reflection of the ambient light when external ambient light is irradiated onto the optical film, thereby improving the anti-reflective capability of the display panel and further improving the contrast of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a preparation method of an optical film, an optical film and a display panel. Background technique [0002] With the evolution of optoelectronic and semiconductor technology, it has also led to the vigorous development of flat panel displays. Among many flat panel displays, Liquid Crystal Display (LCD) has high space utilization efficiency, low power consumption, no radiation and low electromagnetic Many superior features such as interference have been applied to all aspects of production and life. [0003] However, when the display device is used outdoors or in a high-brightness environment, the screen of the display device easily reflects ambient light, which reduces the contrast ratio of the display device. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide a method for preparing an optical film, an optical film and a display panel, ...
