Display Panel Data Compression Using Common Parameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face increased manufacturing and driving costs due to the need to store and transmit large amounts of compensation data to improve display effects, with existing data compression methods requiring individual analysis for each panel and causing a high workload in mass production.
Innovation Solution
A display panel incorporating a data compression unit that compresses first compensation data into second compensation data using a common parameter, reducing bit width and enabling decompression back to the original data, allowing for the same bit width for both, and using a preset detection method to acquire the common parameter, which simplifies the compression and decompression process and reduces costs by eliminating the need for programmable circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If individual analysis and custom compression methods are used for each display panel, then data compression effectiveness is improved, but manufacturing workload and complexity increase significantly
Solution Approach 1:
The patent applies parameter changes by using a common offset value (parameter) that can be universally applied across different display panels. Instead of performing individual analysis for each panel, the system changes the compression approach to use a shared parameter that works for all panels, thereby reducing manufacturing workload while maintaining compression effectiveness.
Solution Approach 2:
The patent implements universality by creating a common compression method that serves all display panels simultaneously. The same offset value and compression algorithm are used across multiple panels, making the system multi-functional and eliminating the need for individual panel analysis, thus resolving the contradiction between compression effectiveness and manufacturing productivity.
2Extent of automation
If complex programmable circuits are used for data compression, then data processing capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the complex programmable circuit functionality and replaces it with a simpler implementation. By taking out the need for complex automation circuits and using a common offset-based compression method instead, the patent reduces device complexity while maintaining adequate data processing capability for compensation data compression.
Solution Approach 2:
The patent uses a simple, disposable-like approach by employing a common offset value that can be easily applied and discarded, rather than investing in complex, expensive programmable circuits. This simple compression method is applied uniformly across all panels, reducing both device complexity and manufacturing cost while maintaining functional adequacy.
