Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Combining two rigid display screens to form a borderless, extended display area while maintaining portability has been a technical challenge, as existing solutions often require flexible screens, increasing cost and complexity.
Innovation Solution
A dual-screen electronic apparatus with rigid display screens and a processor that controls the screens to adjust their angle and arrangement, allowing for a borderless connection by hiding physical borders and using rotating shafts to change the display configuration between modes, enabling a compact and expandable display system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If flexible display screens are used to combine two independent display screens, then the display area is extended, but the cost and system complexity increase
Solution Approach 1:
The display system is divided into two independent rigid display screens that can be separately manufactured and assembled. Each screen operates as an independent unit with its own physical border, eliminating the need for complex flexible screen structures while achieving extended display area through the combination of two separate components.
Solution Approach 2:
The patent introduces a third dimension by allowing the display screens to be arranged on opposite surfaces of a housing structure. This spatial arrangement enables the screens to be positioned in a folded or bent configuration, achieving extended display area without requiring the screens to be physically connected in a planar arrangement, thus reducing structural complexity.
2Area of stationary object
If two rigid display screens are combined to form a borderless connection, then the display area is extended, but the physical borders and housing portions become visible
Solution Approach 1:
The patent positions the first display screen on the first surface and the second display screen on the second surface of the housing, utilizing the third dimension (depth/folding) to hide the physical borders from view. When the housing is folded or bent, the borders are concealed on the inner surfaces, creating a borderless appearance from the outer view while maintaining the extended display area.
3Shape
If the display screens are arranged on opposite surfaces to hide borders, then the visual appearance is improved, but the device structure becomes more complex
Solution Approach 1:
The housing structure serves multiple functions simultaneously: it provides mechanical support for both display screens, enables the folding or bending configuration, and acts as a concealing structure for the physical borders. By integrating these functions into a single multi-functional component, the patent reduces the need for additional separate structures, thereby limiting the increase in overall device complexity.
4Device complexity
If the first display screen and second display screen are arranged on the same surface, then the structure is simpler, but the physical borders are exposed and visual consistency is compromised
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional folded arrangement, positioning the display screens on opposite surfaces of the housing. This spatial reconfiguration utilizes the third dimension to conceal the physical borders while maintaining structural simplicity, as the same housing structure provides both support and concealment functions.

AI summary
A dual-screen electronic apparatus is provided. The apparatus includes: a first display screen with a first physical border; a second display screen with a second physical border; and a processor, configured to control display of the first display screen and the second display screen. In response to a first mode of use, a first portion of the second physical border and a second portion of the first physical border are hidden from view; and in response to a second mode of use, the first display screen is arranged on a first surface of the dual-screen electronic apparatus, and the second display screen is arranged on a second surface of the dual-screen electronic apparatus, the first surface being opposite to the second surface.
