Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with dual display screens face challenges in automatically adjusting content display when rotated and in controlling audio output units, while also struggling with the thickness and weight of the devices due to separate backlight systems for each screen.
Innovation Solution
A method and system where electronic devices with tiled display units adjust content display based on edge alignment, using sensors to determine tiling edges and control audio output units to ensure proper audio signal distribution, and a dual-display system with a shared backlight setup to reduce thickness and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate sets of light source and backlight systems are used for dual display screens, then each screen can be independently illuminated, but the thickness and weight of the device become twice that of a single display screen
Solution Approach 1:
The patent combines two separate backlight systems into a single shared backlight system. The first and second display screens are positioned on opposite sides of the same light source and backlight assembly, allowing both screens to be illuminated simultaneously by one backlight unit. This merging approach reduces the overall weight and thickness of the device while maintaining independent illumination capability for each display screen.
2Weight of stationary object
If a single light source and backlight system is shared for dual display screens, then device thickness and weight are reduced, but controlling the backlight for two independent screens becomes more complex
Solution Approach 1:
The patent implements dynamic control of the shared backlight system through a control unit that can independently adjust the backlight for each display screen based on operational mode. When only one screen is active, the backlight is directed to that screen; when both screens are active, the backlight illuminates both simultaneously. This dynamic switching capability manages the complexity of controlling a shared backlight system for two independent displays.
3Ease of operation
If display content is manually adjusted when devices are re-tiled, then proper display orientation can be achieved, but user operation time increases
Solution Approach 1:
The patent implements automatic detection and adjustment of display content orientation through proximity sensors and a control unit. When electronic devices are tiled together, the sensors detect the relative positions and edges of the devices, and the control unit automatically rotates or adjusts the display content to maintain proper orientation. This self-service mechanism eliminates the need for manual user adjustment, saving time while ensuring accurate display orientation.
4Productivity
If audio output units are not controlled during tiling, then all audio units can output signals, but audio signal distribution becomes incorrect
Solution Approach 1:
The patent implements feedback control for audio output units based on the tiling configuration of electronic devices. Proximity sensors detect which edges of devices are adjacent to each other, and this information is fed back to the control unit. The control unit then selectively activates or deactivates specific audio output units based on the detected tiling arrangement, ensuring correct audio signal distribution across the tiled display system while maintaining overall audio output capability.
