LIGHT ABSORPTION ANISOTROPIC FILM, VIEWING ANGLE CONTROL SYSTEM, AND IMAGE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18331816 titled 'LIGHT ABSORPTION ANISOTROPIC FILM, VIEWING ANGLE CONTROL SYSTEM, AND IMAGE DISPLAY DEVICE
Simplified Explanation
The patent application describes a light absorption anisotropic film that can display a bright, clear image in a specific direction and make the image invisible from other angles. The film is used in an image display device and a viewing angle control system.
- The light absorption anisotropic film contains a liquid crystal compound and an organic dichroic substance.
- The film has different alignment directions of the organic dichroic substance on its surfaces, creating an anisotropic effect.
- The angle difference between the alignment directions is 15° or less, and one of the angles is between 5° and 45°.
Potential Applications
- Privacy screens for electronic devices, such as smartphones and laptops.
- Display systems in public spaces where specific information needs to be visible only to certain viewers.
- Security systems where sensitive information needs to be protected from unauthorized viewing.
Problems Solved
- Provides a solution for controlling the viewing angle of an image display device.
- Addresses the issue of privacy by making the displayed image invisible from unintended angles.
- Solves the problem of limited visibility in public spaces by ensuring that the image is only visible to viewers in the desired direction.
Benefits
- Allows for the display of bright and clear images in a specific direction.
- Enhances privacy by preventing others from viewing the displayed image from unintended angles.
- Provides flexibility in controlling the visibility of displayed information.
- Can be applied to various electronic devices and display systems.
Original Abstract Submitted
A light absorption anisotropic film that displays a bright, clear image in a desired direction and makes the image invisible from other than the desired direction using an image display device, a viewing angle control system formed of the light absorption anisotropic film, and an image display device formed of the light absorption anisotropic film. The light absorption anisotropic film includes a light absorption anisotropic layer that contains a liquid crystal compound and an organic dichroic substance, where an angle between an alignment direction of a light absorption axis of the organic dichroic substance on one surface and on the other surface of the light absorption anisotropic layer and a normal line of the light absorption anisotropic layer is defined as θA and θB, a difference between the angle θA and the angle θB is 15° or less, and the angle θA is 5° or greater and less than 45°.
