Abstract
The invention relates to a viewing angle adjusting film structure, a manufacturing method thereof and a display device. The viewing angle adjusting film structure comprises a base body, an isotropic optical material layer and a liquid crystal layer which are sequentially arranged in a stacked mode, a groove is formed in the isotropic optical material layer, the liquid crystal layer fills the groove, and light is emitted out through the isotropic optical material layer after being emitted in from the liquid crystal layer; the director of liquid crystal molecules in the liquid crystal layer is changed according to the change of externally applied voltage or electric field so as to adjust the viewing angle of light emitted from the isotropic optical material layer; when the director is parallel to the base body, the refractive index of the liquid crystal layer is the same as that of the isotropic optical material layer; when the director is perpendicular to the base body, the refractive index of the liquid crystal layer is smaller than that of the isotropic optical material layer, and therefore the problem that the display image quality is deteriorated when a display panel is viewed from the front viewing angle due to the fact that the front viewing angle display brightness and the front viewing angle contrast ratio of an existing viewing angle diffusion film to the display panelare reduced can be solved.
Description
【Technical field】 [0001] The present application relates to the field of display technology, in particular to a viewing angle adjustment film structure, a manufacturing method thereof, and a display device. 【Background technique】 [0002] With the rapid development of display technology, the market has higher and higher requirements for the resolution of the display panel, and the higher the resolution of the display panel, the worse the display brightness performance of the corresponding display panel at a large viewing angle. Therefore, the reduction of the display brightness at a large viewing angle is UHD display panels urgently need to solve technical problems. [0003] In the prior art, the viewing angle diffusion film is used to modulate the light at the front viewing angle to a large viewing angle, so as to increase the display brightness of the display panel at a large viewing angle. However, this will lead to a loss of display brightness of the display panel at a ...
