Abstract

The invention provides an optical film and a display screen. The optical film comprises a substrate, a first optical layer arranged on the substrate and a second optical layer arranged on the first optical layer, the first optical layer comprises a plurality of optical components with at least one protrusion, the optical components are arranged in a separated mode, the protrusions face the side away from the substrate, the second optical layer covers the first optical layer, and the second optical layer covers the second optical layer. The refractive index of the second optical layer is greater than that of the first optical layer; according to the invention, the optical film is arranged to be of the integral structure formed by compounding the first optical layer and the second optical layer, so that the effects of improving the wide-viewing-angle brightness and reducing the reflectivity can be achieved, and the problem that the optical property of a composite film is changed relative to that of a single film does not exist; and the compounding process of the first optical layer and the second optical layer is relatively simple, so that the production cost, the time cost and the labor cost can be effectively reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an optical film and a display screen. Background technique [0002] Wide viewing angle brightness and low reflectivity are two important optical specifications for large-size displays. The brightness of large-size displays becomes worse and worse as the viewing angle increases. In order to solve this problem, viewing angle improvement films are usually used at this stage to improve the viewing angle brightness at large angles. Since the viewing angle improvement film itself has a high reflectivity, it is necessary to attach an anti-reflection film (also called an anti-reflection film) on the panel in order to take into account the wide viewing angle specifications and low reflectivity specifications of the display, that is, two kinds of Or a multi-functional membrane for compounding. [0003] However, after the multi-layer diaphragm is compounded, the optical propert...
