VEHICLE DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345390 titled 'VEHICLE DISPLAY DEVICE
The vehicle display device described in the abstract includes a housing with an opening facing a windshield, an image display device, a mirror, and a transparent cover.
- The image display device outputs display light of an image, which is reflected by the mirror towards the windshield.
- The transparent cover is curved towards the inside of the housing in a cross-section orthogonal to an image lateral direction.
- The inner surface of the cover is a free-form surface designed to correct distortion or aberration of the image.
- The angular difference between the outer and inner surfaces is set to prevent total reflection of external light incident on the inside of the cover.
Potential Applications: - Automotive industry for heads-up displays - Navigation systems in vehicles - Augmented reality applications
Problems Solved: - Correcting distortion or aberration of images displayed on windshields - Preventing total reflection of external light inside the cover
Benefits: - Improved visibility and clarity of displayed images - Enhanced safety by reducing distractions for drivers
Commercial Applications: - Automotive manufacturers - Technology companies developing augmented reality solutions
Questions about the technology: 1. How does the curved transparent cover help in correcting image distortion? 2. What are the specific advantages of using a mirror to reflect display light towards the windshield?
Original Abstract Submitted
a vehicle display device includes a housing that has an opening facing a windshield, an image display device that outputs display light of an image, a mirror that reflects the display light toward the windshield, and a transparent cover that is disposed in the opening, in which the cover has an outer surface facing the windshield and an inner surface facing the mirror, and has a shape curved toward the inside of the housing in a cross section orthogonal to an image lateral direction, the inner surface is a free-form surface formed to correct distortion or aberration of the image, and an angular difference between the outer surface and the inner surface in the cross section is set to a value within a range in which external light incident on the inside of the cover from the outer surface is not totally reflected inside the cover.
