Solution Overview
Problem
Existing multi-panel display devices require complex driving circuits and conversion boards, leading to increased fabrication costs and noise due to extended video data transmission lengths and the need for multiple scalers and data distributors.
Innovation Solution
A multi-panel display device with data converters that align and convert video data for multiple flat panel displays in various formations, eliminating the need for separate video data distributors and scalers by using ID signals, frequency converters, and memory units to adjust signal frequencies and data sizes based on user-input offset information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conversion board (scaler) is provided for each flat panel display device, then the video data can be converted to fit the size of each display device, but the device complexity and fabrication cost increase
Solution Approach 1:
The patent merges the video data conversion functionality into a single shared conversion board that serves multiple flat panel display devices. Instead of having separate scalers for each display device, one conversion board processes video data and distributes it to multiple displays, thereby reducing device complexity and fabrication cost while maintaining the adaptability to convert video data to fit different display sizes through programmable control
Solution Approach 2:
The conversion board is designed with universal functionality to handle video data conversion for multiple different display devices. It can adaptively convert video data to fit various display sizes and configurations through programmable control, eliminating the need for dedicated conversion boards for each display device while maintaining full conversion capability
2Adaptability or versatility
If video data is transmitted through extended transmission paths to reach each display device, then all display devices can receive video data, but noise occurs due to the extended transmission length
Solution Approach 1:
The patent consolidates the video data distribution path by having the conversion board process and distribute video data in a centralized manner. This reduces the overall transmission path length compared to having separate transmission paths from multiple sources, thereby minimizing noise while maintaining the capability to distribute video data to all display devices
3Manufacturing precision
If multiple conversion boards and data distributors are used, then each display device receives appropriately converted video data, but the fabrication cost increases
Solution Approach 1:
The patent combines multiple conversion boards into a single shared conversion board that serves multiple display devices. This consolidation significantly reduces fabrication cost by eliminating redundant conversion boards while maintaining video data conversion accuracy through programmable control that can adaptively process video data for different display configurations
Solution Approach 2:
The single conversion board is designed with universal functionality to accurately convert video data for multiple different display devices. It maintains manufacturing precision through programmable control that can adapt to various display sizes and configurations, eliminating the need for multiple dedicated conversion boards while preserving conversion accuracy
