Cylindrical Display Screen for Immersive Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dome screens in existing display technologies often result in discomfort for audiences seated far from the center due to high inclination, necessitating a larger radius and increased manufacturing costs to maintain viewer comfort.
Innovation Solution
A display screen with a cylindrical housing structure featuring a cross section that can be circular, elliptical, or quadrangular with rounded corners, allowing for a smooth transition and adjustable end portions, which provides a 180-360 degree view angle while reducing the volume and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a dome screen is used to create immersion, then the sense of immersion is improved, but the viewing comfort for side-seated audiences deteriorates due to high inclination angles
Solution Approach 1:
The patent applies spherical geometry to create a dome screen that encloses audiences, providing immersive 360-degree viewing. The curved surface allows audiences to view images from multiple angles while maintaining comfortable viewing distances, resolving the contradiction between immersion and comfort through geometric design.
2Ease of operation
If the dome screen radius is increased to improve side-seated audience comfort, then viewing comfort is improved, but the manufacturing cost increases
Solution Approach 1:
The patent implements a partially-dome screen design that provides sufficient immersion and comfortable viewing angles without requiring a full 360-degree dome structure. This partial implementation reduces manufacturing complexity and cost while maintaining the essential benefits of dome screening for side-seated audiences.
3Ease of manufacture
If a seamless rear projection dome display system is implemented, then the sense of immersion is improved, but the construction complexity and cost increase
Solution Approach 1:
The patent divides the dome screen into multiple spliced segments rather than requiring a single seamless structure. This segmentation simplifies construction by allowing modular assembly of smaller screen sections, reducing the overall complexity while maintaining the immersive dome experience.

AI summary
Embodiments of the present application provide a display screen, wherein the display screen is in a fully-closed or partially-closed housing structure, an interior of the housing structure being configured to provide continuous images with a view angle of 180 degrees to 360 degrees in a horizontal direction; wherein the housing structure includes a cylindrical portion, a side wall of the cylindrical portion being arranged in a smooth arc line or straight line on an axial cross section, and if the side wall of the cylindrical portion is arranged in the arc line, the radius of a circle corresponding to the arc line is greater than a maximum vertical distance from the arc line to an axial line. According to the present application, the audiences feel comfortable in watching and the cost is saved, while a strong sense of immersion is achieved for the audiences.
