  • Publication number: 20230062823
    Abstract: An optical film for a sub-millimeter light emitting diode (MiniLED) backlight module and a method for preparing the optical film are disclosed. The MiniLED backlight module includes a diffusion film, an optical film, a reflection film and MiniLED chips. The diffusion film is provided above the optical film. The reflection film is provided under the MiniLED chips. The MiniLED chips are provided between the reflection film and the optical film. The first end of the optical film includes multiple first microstructures. The second end of the optical film includes multiple second microstructures. In the disclosure, photoresists are spin-coated on one end of an optical film substrate. A lithography direct write process is adopt to form a microstructure morphology on the surface of the OCA. The morphology is cured after development and hot baking to obtain an optical film.

  • Publication number: 20190121200
    Abstract: The application relates to a fabrication method of a deflecting film capable of realizing a deflection of a viewing angle of the liquid crystal display device. According to viewing angle characteristics of a backlight unit of the liquid crystal display device and deflection angle requirement of maximum luminance, one or more layers of deflecting film is/are fabricated and used in the backlight unit of the liquid crystal display device. The deflecting film deflects a viewing angle of the maximum luminance of the liquid crystal display device to the direction of the viewer's sight, and a shape of the viewing angle curve does not change significantly, so that the light is utilized to the utmost extent, the energy consumption is reduced, and the light effect is improved.
