Arc-shaped Hyperboloid Display Screen with Integrated Sound Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-size screens with single curved surfaces provide limited immersion due to inadequate inclusiveness and poor coordination of video and audio experiences, leading to a suboptimal viewing experience.
Innovation Solution
An arc-shaped hyperboloid display screen featuring a frame with detachably mounted trapezoidal or quadrilateral LED display unit boards, forming a pixel matrix with sound transmitting gaps or holes, offering wider viewing angles and high fidelity sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a single curved surface screen is used, then the viewing angle is larger than flat screen, but the immersion feeling is not strong enough
Solution Approach 1:
The patent applies double curvature (hyperboloid shape) to the display screen instead of single curvature. The screen surface is formed with both meridian and parallel curvatures, creating a more encompassing spatial form that surrounds viewers on multiple sides, thereby enhancing immersion feeling while maintaining the viewing angle benefits of curved surfaces.
2Ease of operation
If audio system is provided around the screen, then audio coverage is improved, but the coordination of video and audio experience deteriorates
Solution Approach 1:
The patent merges the audio system with the display screen structure itself. Audio outlets are integrated into the gaps between display modules and the frame structure, rather than being separate components around the screen. This integration ensures that audio and video originate from the same spatial location, improving coordination while still providing surround sound coverage.
3Stability of the object's composition
If rigid display units are used, then structural stability is improved, but the flexibility of screen configuration deteriorates
Solution Approach 1:
The patent segments the display screen into multiple independent display modules that can be individually configured. Each module is a rigid unit with stable structure, but the collection of modules can be arranged in different patterns (circular, rectangular, custom shapes) by adjusting their positions and orientations, thus achieving both structural stability and configuration flexibility.

AI summary
An arc-shaped display screen with double-curved surface includes an arc-shaped frame and a plurality of LED display unit boards. The plurality of LED display unit boards are mounted on an inner surface or an outer surface of the arc-shaped frame in a detachable manner, and surfaces of the plurality of LED display unit boards constitute the arc-shaped display screen with double-curved surface. The frame is formed by splicing a plurality of structural units, and adjacent structural units are fixedly connected to each other. Each of the LED display unit boards is electrically connected to an external circuit. The arc-shaped display screen with double-curved surface has a simple structure and low cost. Moreover, compared with the movie screens of the existing screens with single curved surface, the arc-shaped display screen with double-curved surface has wider viewing angle, ultra-high picture definition, and high-fidelity sound quality etc.
