Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal generating systems for liquid crystal display panels are inadequate for driving larger screens, as they require 10-bit LVDS signals for sizes over 42 inches, while existing 8-bit systems are insufficient, leading to resource wastage and inefficiency.
Innovation Solution
A signal conversion device and method that rearranges and converts pixel signals from a first arrangement order into display signal packets in different formats, allowing the existing systems to drive larger display panels by utilizing a patch unit and signal conversion chip to generate and output display signal packets in formats suitable for both smaller and larger sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an existing signal generating system with 8-bit LVDS signals is used, then it can drive liquid crystal display panels with size smaller than 42 inch, but it cannot drive liquid crystal display panels with size more than 42 inch
Solution Approach 1:
The patent segments the pixel signals into multiple groups and processes them through different signal paths. By dividing the RGB pixel signals into multiple channels and processing each channel separately with appropriate bit-depth conversion, the system can output both 8-bit and 10-bit LVDS signals simultaneously, enabling compatibility with different display panel sizes without requiring a complete system redesign.
Solution Approach 2:
The patent implements a universal signal conversion system that can handle multiple display panel sizes and signal requirements through a single apparatus. By incorporating multiple signal conversion chips and patch units that can process both 8-bit and 10-bit signals, the system achieves multi-functionality, allowing one system to drive both small (≤42 inch) and large (>42 inch) display panels.
2Adaptability or versatility
If a new signal generating system with 10-bit LVDS signals is developed to drive large-sized display panels, then it can drive liquid crystal display panels with size more than 42 inch, but existing 8-bit systems become useless and resources are wasted
Solution Approach 1:
The patent merges the functionality of both 8-bit and 10-bit signal generation capabilities into a single unified system. By combining multiple signal conversion chips and patch units that can process different bit-depth signals, the system allows existing 8-bit signal generating systems to continue operating while simultaneously supporting 10-bit signals for large display panels, thus avoiding resource wastage and extending the lifecycle of existing equipment.
Solution Approach 2:
The patent introduces dynamic signal routing and conversion capabilities that can adapt the signal processing path based on the connected display panel requirements. The system can dynamically switch between 8-bit and 10-bit signal modes, rearrange pixel signal arrangements, and adjust conversion processes in real-time, allowing existing systems to remain useful while gaining enhanced capabilities for large display panels.
3Adaptability or versatility
If pixel signals are converted directly without rearrangement, then the conversion process is simple, but the system cannot support both small and large display panel requirements
Solution Approach 1:
The patent introduces patch units as intermediary components between the pixel signal transmitting chip and the signal conversion chips. These patch units perform the necessary signal rearrangement and formatting operations, acting as mediators that enable the system to support multiple display panel sizes. By placing the complexity in dedicated intermediary components rather than throughout the entire system, the solution maintains modularity and manages complexity effectively.
