Attachable Dual Display System for Interactive Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital TV services and smart TV systems face limitations in providing interactive user experiences due to the physical separation of devices, such as smartphones and smart pads, which restricts the ability for users to easily access additional information while watching content.
Innovation Solution
A display system comprising two attachable and detachable display devices, where the first device determines if the second device is attached, and upon attachment, the second device displays related content based on the content being displayed on the first device, allowing for enhanced interactivity and information access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two display devices are physically separated (smartphone and smart pad), then device portability and independence are maintained, but user experience and interactivity are limited
Solution Approach 1:
The patent merges two display devices (main display device and sub display device) into a combined configuration where they can be attached together. When attached, the main display device displays first content and the sub display device displays second content, enabling enhanced interactivity and information access. This merging resolves the contradiction by allowing devices to function independently when separated yet provide enhanced user experience when combined.
Solution Approach 2:
The patent implements a dynamic system where the display configuration can change between separated and attached states. The controller detects the attachment state and dynamically adjusts the display mode - when attached, it enables dual-content display with enhanced interactivity; when separated, it maintains independent operation. This dynamic adaptability resolves the contradiction between portability and enhanced user experience.
2Adaptability or versatility
If two display devices are attached together, then interactivity and information access are enhanced, but device complexity increases
Solution Approach 1:
The patent segments the display system into distinct functional modules: a main display device with first content display capabilities and a sub display device with second content display capabilities. Each device maintains its own controller and display interface, allowing them to function independently while enabling enhanced interactivity when attached. This segmentation reduces system complexity by keeping each unit relatively simple while achieving complex functionality through their combination.
3Loss of information
If additional display functionality is added to provide sub-screen content, then information access is improved, but ease of operation becomes more complex
Solution Approach 1:
The patent implements a self-service mechanism where the controller automatically detects the attachment state of the sub display device and autonomously switches between different display modes. When the sub display device is attached, the controller automatically enables dual-content display, displaying first content on the main display device and second content on the sub display device. This automation eliminates the need for manual configuration and simplifies user operation while providing enhanced information access.

AI summary
In a display system comprising a first display device and a second display device according to an embodiment of the present invention, the first display device determines whether the second display device is attached, and when it is determined that the second display device is attached, the second display device can display, on the basis of a first content image being displayed, a second content image related to the first content image.
