Display Compensation Data Segmentation for Memory Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large amount of compensation data stored in memory for display devices consumes excessive memory space, increasing costs and affecting the operation efficiency of timing sequence controllers.
Innovation Solution
A data processing method that captures image data in preset grayscale, determines compensation data for display defects, and generates compensation data using this information, reducing the need to store the entire compensation data, thereby minimizing memory requirements and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire compensation data is stored in memory, then the display defect compensation is complete and accurate, but the memory space occupation increases and costs rise
Solution Approach 1:
The patent segments compensation data into two parts: grayscale compensation data (stored in memory) and color deviation compensation data (calculated in real-time). This segmentation allows the system to store only essential data while computing derived data on-demand, reducing memory space occupation while maintaining complete compensation functionality
Solution Approach 2:
The patent performs preliminary calculation of compensation data during the manufacturing or calibration phase, storing only the essential grayscale compensation data in memory. The color deviation compensation data is pre-computed and stored in a lookup table, enabling fast retrieval without occupying large memory space during operation
2Quantity of substance
If large memory is allocated for compensation data, then the compensation data can be stored completely, but the timing sequence controller cost increases
Solution Approach 1:
The patent extracts and separates the color deviation compensation data from the main compensation data set that needs to be stored in memory. By taking out this component and handling it through real-time calculation or lookup table operations, the system reduces the memory capacity requirement, thereby lowering the timing sequence controller cost while maintaining complete compensation functionality
3Ease of operation
If all compensation data is stored in memory, then the compensation can be applied directly, but the operation efficiency of timing sequence controller decreases
Solution Approach 1:
The patent introduces dynamic calculation for color deviation compensation data, which is computed in real-time based on the grayscale compensation data and image characteristics. This dynamic approach allows the system to adapt compensation parameters on-the-fly without being constrained by static pre-stored data, improving operational efficiency while maintaining compensation effectiveness
