Problems solved by technology

[0007] The main purpose of the present invention is to provide a multilayer optical film structure, aiming at increasing the thickness of the substrate by one unit layer for the existing multilayer optical film, which results in a substantial increase in the volume and weight of the optical film and the gap between the optical refraction layers. To break through the problems of difficult alignment, high cost and defective rate

Abstract

The invention discloses a multilayer optical membrane structure, comprising: a substrate having thickness and length and width specifications and equipped with first and second surfaces; first light refraction layer, bonded with the first or second surface of the substrate; the first light refraction layer comprises inclined refraction surface; at least a second light refraction layer stacked on the first light refraction layer and comprising inclined refraction surface. Thus, it can largely reduce the thickness of multi-layer optical membrane and obtain the optimum light focusing and brightening effect by the minimum thickness.

Description

technical field [0001] The invention relates to an optical film structure, in particular to an innovative design of a combination structure of a base material and a light refraction layer of a multilayer optical film. Background technique [0002] Optical films are widely used in the structure of liquid crystal display panels in practical applications to provide the effect of concentrating light and enhancing brightness. [0003] The optical film structure usually consists of a base material and a light-refractive layer. Since the light-gathering and brightness-enhancing effect of a single-layer light-refractive layer is quite limited, a multilayer optical film was subsequently developed in this field. The structural form is shown in Figure 1, which is a cross-sectional view of the structure of an existing multilayer optical film A, which consists of a substrate 11 and a light-refractive layer 12 on its surface to form a unit 10, and at least two units 10 are stacked on top ...
