==OPTICAL FILM, VIEWING ANGLE CONTROL SYSTEM, AND IMAGE DISPLAY DEVICE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18331807 titled 'OPTICAL FILM, VIEWING ANGLE CONTROL SYSTEM, AND IMAGE DISPLAY DEVICE

==Simplified Explanation==

The present invention is a viewing angle control system and display device that improves image visibility and reduces glare on window glass. It also introduces an optical film with specific properties.

* The optical film includes a light absorption anisotropic layer made of a liquid crystal composition.
* The liquid crystal composition contains a thermotropic liquid crystal compound, a dichroic substance, and an interface improver.
* The dichroic substance makes up at least 10.0% of the total mass of the solid content of the liquid crystal composition.
* The angle between the transmittance central axis of the light absorption anisotropic layer and the surface normal direction of the optical film is between 5° and 45°.

Potential applications of this technology:

* Display devices with improved image visibility and reduced glare on window glass.
* Automotive displays that provide clear and bright images even in direct sunlight.
* Outdoor digital signage that remains visible from various viewing angles.

Problems solved by this technology:

* Poor image visibility and glare on window glass can make it difficult to see displayed content.
* Traditional optical films may not effectively control the viewing angle or reduce reflected glare.

Benefits of this technology:

* Provides a bright and easy-to-see image in the desired direction.
* Shields light from the image in directions other than the desired direction.
* Limits reflected glare on window glass, improving visibility.
* Offers a versatile solution for various display applications.


==Original Abstract Submitted==

The present invention provides a viewing angle control system and a display device that are capable of providing a bright and easy-to-see image in a desired direction, shielding light from the image in a direction other than the desired direction, and limiting reflected glare on window glass, and an optical film therefor. The optical film of the present invention includes a light absorption anisotropic layer formed of a liquid crystal composition containing a thermotropic liquid crystal compound, a dichroic substance, and an interface improver, in which a content of the dichroic substance is 10.0% by mass or greater with respect to a total mass of a solid content of the liquid crystal composition, and an angle θ between a transmittance central axis of the light absorption anisotropic layer and a normal direction of a surface of the optical film is 5° or greater and less than 45°.
