Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted displays have limitations in providing a wide visual field and high definition with a simple optical system, and they often require complex and costly optical designs, which hinders their application in immersive display devices for VR, AR, and MR applications.
Innovation Solution
A direct-view image display device with a flexible, curved surface is used, featuring a switching element or light-emitting element on a flexible film, allowing for a wide visual field without an optical system and enabling high-definition, high-resolution displays that can be placed on various parts of the user's head, including the front, sides, and rear, with optional gaze detection for foveated rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a projection head mounted display with a complicated optical system is used, then a wide visual field can be achieved, but the design and manufacturing cost increases significantly
Solution Approach 1:
The patent removes the optical system from the head mounted display, extracting the complicating elements while retaining the core display function. By using a direct-view display device without optical components, the patent eliminates lenses, mirrors, and other optical elements that increase complexity and cost, while still achieving a wide visual field through the flexible curved display surface that can wrap around the user's head.
Solution Approach 2:
The patent replaces the mechanical optical system with a direct-view electronic display. Instead of using optical components to project images, the display device directly presents images to the user's eyes through a flexible curved screen, substituting a complex mechanical optical system with a simpler electronic display system that achieves the same visual field expansion goal.
2Device complexity
If a direct-view image display device is used, then manufacturing cost and complexity are reduced, but achieving high definition and large screen with wide visual field is difficult
Solution Approach 1:
The patent employs a curved display surface that follows the contour of the user's head, creating a spherical or hemispherical viewing area. This curvature allows the display to wrap around the user's field of view, expanding the visual field without requiring optical components. The curved geometry enables a large-screen effect while maintaining direct-view simplicity, achieving both wide coverage and high definition through the flexible curved panel technology.
3Adaptability or versatility
If a flexible curved display is placed on the user's head, then immersive experience is improved, but the device structure becomes more complex
Solution Approach 1:
The patent utilizes a flexible thin-film display structure that can be conformally placed on various surfaces of the user's head. This flexible film technology allows the display to adapt to curved geometries without requiring complex rigid mounting structures or mechanical support systems. The thin-film construction provides structural simplicity while enabling versatile placement options that enhance immersive experience through direct contact with the user's head surface.

AI summary
High definition and a large screen are achieved with the use of a direct-view image display device including a small number of optical systems or no optical system. A personal image display device providing the sense of immersion is achieved. A display device of the present invention is a display device placed at least on the front side of a user's visual field. The display device uses a flexible film, has a curved surface, and has a display surface on the user's side of the display device. Display is performed inside a space on the user's side of the display device, and the rear surface of the display device is placed on the side opposite to the user's side of the display device. The user's side of the display device may be provided with a large display region, or a see-through display region of the display device may display only some marks.
