Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-panel display devices require complex driving circuits and conversion boards, leading to increased fabrication costs and decreased production efficiency due to the need for multiple scalers and data distributors to synchronize and align video data across multiple flat panel display devices.
Innovation Solution
A multi-panel display device configuration with a timing controller that divides and converts image data and synchronization signals to align and size-match each display panel, eliminating the need for separate video data distributors and scalers by using a data modulator, frequency converter, and control signal generator to drive multiple flat panel display devices in various alignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple conversion boards (scalers) are used for each flat panel display device, then video data can be converted to fit each display device's position, size, and driving frequency, but the device complexity and fabrication cost increase
Solution Approach 1:
The patent merges multiple separate conversion boards into a single timing controller that serves all flat panel display devices. The timing controller integrates video data distribution, scaling, and synchronization functions that were previously handled by individual conversion boards for each display device, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The timing controller is designed as a universal device that can handle video data conversion for multiple different display devices simultaneously. It performs scaling, frequency conversion, and synchronization for various panel sizes and specifications through a single multi-functional unit, eliminating the need for dedicated conversion boards for each display device.
2Adaptability or versatility
If multiple conversion boards with A/D converters, frequency converters, and high capacity memory units are used, then video data conversion is achieved, but fabrication cost increases
Solution Approach 1:
The patent combines multiple expensive conversion components (A/D converters, frequency converters, memory units) that were previously required for each display device into a single timing controller. This consolidation significantly reduces the total component count and fabrication cost while maintaining all necessary signal conversion functions for multiple display devices.
Solution Approach 2:
Instead of having physical conversion components for each display device, the timing controller generates timing signals and scaled video data that are distributed to multiple display devices. The conversion function is effectively copied through signal distribution rather than physical replication of expensive components at each display device location.
3Ease of operation
If image data is distributed to each display device through a video data distributor and converted by separate conversion boards, then each display device receives appropriate video data, but the driving circuit becomes complicated
Solution Approach 1:
The patent merges the video data distributor and conversion board functions into a single timing controller. The timing controller receives video data, performs scaling and frequency conversion, and directly outputs the processed data to multiple display devices, eliminating the need for separate distribution and conversion stages.
Solution Approach 2:
The patent extracts the complex distribution and conversion functions from the individual display device paths and consolidates them into the timing controller. This removes the complexity from the driving circuit by centralizing the data processing functions in a single location rather than replicating them across multiple paths.
