IMAGE DISPLAY DEVICE AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18264283 titled 'IMAGE DISPLAY DEVICE AND DISPLAY DEVICE
Simplified Explanation
The image display device described in the patent application is designed to improve display at the fovea of an eye, which is the most important part in a display range, by ensuring that display at the fovea of the eye is not darkened.
- Two optical elements facing each other
- First optical element with a deflection function
- Second optical element with a lens function
- Incident light is deflected by the first optical element and emitted as first diffracted light
- First diffracted light is further manipulated by the second optical element
- Direction of incident light and diffraction angle of first diffracted light are different from the optical axis of the second optical element
Potential Applications
This technology could be applied in:
- Virtual reality headsets
- Heads-up displays in vehicles
- Medical imaging devices
Problems Solved
- Darkening of display at the fovea of the eye
- Improved image quality in the most critical part of the display range
Benefits
- Enhanced visual experience
- Increased comfort during prolonged use of display devices
Potential Commercial Applications
- Consumer electronics industry
- Healthcare sector
- Automotive industry
Possible Prior Art
One possible prior art for this technology could be the use of eye-tracking systems in display devices to optimize image quality at the fovea of the eye.

Original Abstract Submitted
To provide an image display device capable of improving display at a fovea of an eye, which is the most important part in a display range, such that display at the fovea of the eye is not darkened. There is provided an image display device including: at least one optical element unit including two optical elements facing each other, in which one optical element unit included in the at least one optical element unit includes a first optical element and a second optical element, an image is formed on the basis of image display light which transmits through the first optical element and is emitted to outside of the image display device, the first optical element has a deflection function of deflecting incident light which has a predetermined wavelength and is incident on the first optical element at a predetermined incidence angle to a side of the first optical element on which the incident light is incident, and emits first diffracted light deflected by the deflection function, the second optical element has a lens function for the first diffracted light which has a predetermined wavelength and is incident on the second optical element at a predetermined incidence angle, and a direction of the incidence angle of the incident light and a direction of a diffraction angle of the first diffracted light are different from a direction of an optical axis of the second optical element.
