Multi-Panel Display Sound Synchronization Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display systems using multiple display apparatuses, it is challenging for users to recognize sound output from individual loudspeakers, especially in configurations where images are divided across multiple panels, as the sound output is not effectively synchronized with the visual content across the displays.
Innovation Solution
A display apparatus with integrated loudspeakers, a signal processor, and a controller that processes image signals and adjusts sound output based on preset designation states, determining the divided and displayed state of images across multiple display apparatuses and adjusting sound output accordingly, using a communication interface to coordinate with external display apparatuses and store image display modes and sound output profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display apparatuses are arranged to form a display system, then the display area is increased, but the sound output from individual loudspeakers becomes difficult to recognize
Solution Approach 1:
The patent applies local quality by directing sound from specific loudspeakers based on the divided display regions. Each display apparatus has loudspeakers that output sound corresponding to the specific image region displayed on that apparatus, creating localized sound zones that match the visual content distribution across the multi-panel display system.
Solution Approach 2:
The patent segments the sound output control by dividing the display area into multiple regions corresponding to different display apparatuses. The controller determines which display apparatus displays which image region and controls the corresponding loudspeakers to output sound for that specific region, creating segmented sound zones that improve sound recognition in multi-panel configurations.
2Adaptability or versatility
If images are divided across multiple display apparatuses, then the display capability is enhanced, but the synchronization between sound and visual content becomes difficult
Solution Approach 1:
The patent implements feedback by having the controller continuously monitor the divided display state and adjust sound output accordingly. The controller determines the current image division configuration and dynamically controls loudspeaker output to match the displayed content, ensuring continuous synchronization between visual and auditory information across multiple display apparatuses.
Solution Approach 2:
The patent applies dynamics by making the sound output configuration adaptive to changing display states. When the image division or display configuration changes, the controller automatically adjusts which loudspeakers output sound and what content they output, allowing the system to maintain sound-visual synchronization across various display modes and configurations.
3Power
If each display apparatus is equipped with loudspeakers, then the sound output capability is improved, but the complexity of controlling sound across multiple apparatuses increases
Solution Approach 1:
The patent merges the sound control function into a centralized controller that manages all loudspeakers across multiple display apparatuses. Instead of each display apparatus independently controlling its own loudspeakers, the single controller determines the divided display state and coordinates sound output from all loudspeakers, reducing overall system complexity while maintaining enhanced sound output capability.
Solution Approach 2:
The controller serves multiple functions: it manages image signal distribution, determines display division states, and controls sound output from multiple loudspeakers. This multi-functional approach consolidates control tasks and reduces the need for separate control mechanisms at each display apparatus, simplifying the overall system architecture.

AI summary
A display apparatus, control method, and system are provided. The display apparatus includes a display; one or more loudspeakers; a signal processor configured to process an image signal so that an image may be displayed on the display and sound may be output from the loudspeaker; a communication interface configured to communicate with one or more external display apparatuses; and a controller configured to transmit sound processed by the signal processor to the one or more loudspeakers in accordance with a preset output designation state, determine a divided and displayed state of an image with respect to the display apparatus and the one or more external display apparatuses, and adjust the output designation state of the sound with respect to the one or more loudspeakers based on the determination.
