Display Identification Switching for Stable External Image Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display apparatuses face issues in stably displaying images when connected to external devices due to mismatched display identification data, leading to damaged portions of the displayed image.
Innovation Solution
The image display apparatus includes a display, an interface for data exchange, a memory to store multiple display identification data, and a signal processing device that decodes and selects appropriate decoders based on received image data resolutions, transmitting corresponding identification data to the external device to ensure stable image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display identification data is transmitted to external device, then image display compatibility is improved, but image display stability deteriorates when data types or versions do not match
Solution Approach 1:
The patent implements dynamic selection of display identification data from multiple stored versions based on the actual image signal received. The system can switch between different data types and versions (e.g., HDMI 1.4, 2.1, 2.1a) depending on the external device's capabilities, making the system adaptable while maintaining stability through intelligent matching.
Solution Approach 2:
The system changes the parameters of display identification data by storing multiple versions with different types and versions. When an image signal is received, the system selects and transmits the appropriate parameter set that matches the external device's capabilities, resolving the contradiction between compatibility and stability.
2Adaptability or versatility
If multiple display identification data are stored and transmitted, then adaptability to different external devices is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple display identification data versions in memory before actual use. This preparation allows the system to quickly select and transmit the appropriate data version when connecting to external devices, reducing real-time complexity while maintaining high adaptability.
Solution Approach 2:
The system achieves universality by designing a single display interface that can handle multiple data types and versions. The display device can universally connect to various external devices (TVs, monitors, projectors) with different capabilities through one interface that automatically selects the appropriate identification data version.
