Display Apparatus Timing Synchronization Without External Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems require a complex configuration with a timing server to synchronize image display timings across multiple display apparatus, leading to an undesirable large-scale setup.
Innovation Solution
A display apparatus with an input section, storage for a set period, operation accepting section, and controller that allows users to input instructions and adjust the display timing, enabling synchronization of image display times across multiple devices in a simple configuration by setting the same period across devices and adjusting input timings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a timing server is used to synchronize display timings, then image display synchronization is achieved, but system complexity increases
Solution Approach 1:
The patent extracts the timing server from the system configuration and replaces it with a timing adjustment mechanism built into each display apparatus. Each device independently adjusts its display timing based on a set period, eliminating the need for external timing management infrastructure while maintaining synchronization reliability
Solution Approach 2:
Each display apparatus autonomously manages its own display timing by incorporating a timing adjustment section that modifies the display timing based on the set period. This self-service approach allows devices to synchronize without requiring a central timing server, reducing system complexity while maintaining reliable synchronization
2Manufacturing precision
If display timing is adjusted by modifying hardware circuits, then precise timing control is achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces hardware circuit modifications with a software-based timing adjustment mechanism. The timing adjustment section uses control software to modify display timing based on the set period, achieving precise timing control without the complexity and cost of hardware circuit changes
Solution Approach 2:
The patent changes the timing parameter through software control rather than hardware modification. The timing adjustment section dynamically adjusts the display timing parameter based on the set period, allowing precise timing control while maintaining simple hardware configuration and reducing device complexity

AI summary
A display apparatus includes a storage that stores a set period that is a period from the point of time when electric power supply starts to the point of time when a projection section starts displaying an image, a remote control that accepts operation, and a controller that changes the set period based on the operation accepted by the remote control, and the controller causes the projection section to start projecting the image after the electric power supply starts and the set period then elapses.
