Abstract

The embodiment of the invention provides an optical film. The optical film comprises: first dielectric layers; second dielectric layers, wherein the second dielectric layers and the first dielectric layers are sequentially and alternately stacked to form a stacked structure, and the refractive index of the second dielectric layers is smaller than that of the first dielectric layers adjacent to the second dielectric layers.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an optical film and a display module. Background technique [0002] A direct display device is a display device in which a light source such as a light-emitting diode (LED for short) is arranged behind a panel, and the light source directly illuminates the panel to display an image. Compared with the side-type display device, the direct-type display device has the advantages of wide color gamut, high contrast and high brightness, but the thickness is relatively large, which is not conducive to the realization of light and thin structure. Contents of the invention [0003] Embodiments of the present application provide an optical film and a display module, which can reduce the thickness of a direct-type display device and realize light and thin structures. [0004] On the one hand, an embodiment of the present application provides an optical film, including: a first ...
