Problems solved by technology

However, according to the design of the above-mentioned composite optical film 5, it is not only difficult to control the warpage variability of the film material, but also the dispersion of the diffusion particles is also prone to complicated technical problems such as variation in uniformity. The particles are easy to cause

Example Embodiment

[0042] The present invention is a multi-layer coating composite optical film structure, which is characterized in that a diffusion layer with an interface microstructure is used as a light diffusion mechanism. The present invention is a microstructure (Microstructure) design using multi-layer coating technology, interface control (Interface-Dominating) of the diffusion layer, and matched with an effective coating layer refractive index difference to obtain a material that provides light diffusion effect, and In terms of structure and mechanism, the scattered light is concentrated by using the optically concentrated microstructure on the outermost layer, so as to improve the brightness value of the front viewing angle (On-axis). The above interface control microstructure design is not particularly limited, such as but not limited to random interface microstructure design, and in the following embodiments, the roughness value (Ra) of the interface microstructure is to obtain a ce...

Abstract

The invention relates to a composite optical film structure with multiple coatings. With a diffusion layer with an interface microstructure as a photo diffusion mechanism, the invention comprises a transparent base material, a multiple coating and a protection coating; wherein a diffusion layer combination of the inner layer of the multiple coating is provided with at least more than one diffusion layer with a port microstructure, a condensation layer at the first surface layer of the multiple coating is provided with an optical rotation microstructure. On the basis, composite design is carried out by light source diffusion as a result of the multiple coating technology and condensation effect; with the optical film structure integrated into an optical film, material cost can be effectively reduced; and when the diffusion layer with the port microstructure serves as the photo diffusion mechanism, not only brightness performance can be effectively improved, meanwhile quality variables created by dispersion of doping ions and film material warpage and the like can also be reduced; as a result, while assembly of a backlight module is simplified to improve assembly efficiency thereof, film material quality and optical property of the composite optical film can also be improved.
