==VEHICLE DISPLAY DEVICE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240345391 titled 'VEHICLE DISPLAY DEVICE

The vehicle display device described in the patent application includes a housing, an image display device, a mirror, and a transparent cover placed in an opening of the housing. The cover has both an outer surface and an inner surface, with a curved shape.

* The cover features a light-blocking wall that shields the outer surface from external light sources.
* The inner surface of the cover is a free-form surface designed to correct image distortion or aberration.
* An angular difference between the inner and outer surfaces in the cross-section is optimized to block external light reflected along an optical path towards an eye point.
* The design of the cover allows for the blocking of external light transmitted through a windshield towards the cover.

Potential Applications:
- Automotive industry for vehicle display systems
- Aviation industry for cockpit displays
- Consumer electronics for curved display screens

Problems Solved:
- Correcting image distortion or aberration in display devices
- Blocking external light interference for better visibility

Benefits:
- Improved image quality in display devices
- Enhanced visibility in varying lighting conditions
- Reduction of glare and reflections for a better user experience

Commercial Applications:
"Advanced Vehicle Display Technology for Enhanced Visibility and Image Quality"

Questions about the technology:
1. How does the curved shape of the cover contribute to correcting image distortion?
2. What are the specific advantages of using a free-form surface on the inner surface of the cover?


==Original Abstract Submitted==

a vehicle display device includes a housing, an image display device, a mirror, and a transparent cover disposed in an opening of the housing, in which the cover has an outer surface and an inner surface and has a shape curved, a light-blocking wall shields the outer surface from first external light, the inner surface is a free-form surface formed to correct image distortion or aberration, an angular difference between the inner surface and the outer surface in the cross section is a value within a range in which second external light can be blocked by the light-blocking wall, and the second external light is external light reflected along an optical path toward an eye point in a case where it is assumed that the external light is incident on the cover and reflected by the inner surface, in external light transmitted through a windshield toward the cover.
