DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18550117 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that uses holograms to improve reliability by compensating for light source variations and external factors.
- The display device includes a light source, a first hologram, and a second hologram.
- The first hologram compensates for light dispersion and diffracts the light, while the second hologram diffracts the light again for emission towards the user.
- The first hologram has varying diffraction efficiency based on the wavelength of the light and its position in the hologram plane.

Original Abstract Submitted
To provide a display device capable of further improving reliability of the display device with respect to manufacturing variations, wavelength variations of light sources, and active variations (variations due to external factors). There is provided a display device including at least a light source, a first hologram, and a second hologram, in which the first hologram compensates for dispersion of light emitted from the light source and diffracts and emits the light, the second hologram diffracts the light diffracted with compensated dispersion, and emits the light in a direction of a pupil of a user, and the first hologram has an intensity distribution of different diffraction efficiency with respect to a wavelength of the light emitted from the light source depending on a position in a plane of the first hologram.
