Display Panel Compensation Grayscale Storage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining compensation grayscale values for display panels require large storage spaces, leading to high production costs due to inefficient data storage.
Innovation Solution
A method and device that classify and store compensation grayscale values based on the number of bits required for each sub-pixel, using separate tables for first and second reading processes to determine the appropriate compensation values, reducing redundant data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform storage method is used for all compensation grayscale values, then the storage process is simple, but the storage space required is large
Solution Approach 1:
The patent segments the storage of compensation grayscale values by dividing them into two categories: first compensation grayscale values (for sub-pixels requiring compensation) and second compensation grayscale values (for sub-pixels not requiring compensation). This segmentation allows the system to store only necessary compensation data, reducing overall storage space requirements while maintaining a relatively simple storage process.
2Measurement precision
If all compensation grayscale values are stored in detail, then the compensation precision is high, but the storage cost increases
Solution Approach 1:
The patent extracts and stores only the necessary compensation grayscale values in separate tables. By identifying which sub-pixels actually require compensation and storing only those values (first compensation grayscale values) along with their corresponding second compensation grayscale values, the system maintains high compensation precision while avoiding the storage cost of redundant data for sub-pixels that do not need compensation.
3Device complexity
If a single table stores all compensation data, then the data structure is simple, but the data retrieval efficiency is low
Solution Approach 1:
The patent divides the compensation data into two separate tables: a first table storing first compensation grayscale values and a second table storing second compensation grayscale values. This segmentation enables more efficient data retrieval by allowing the system to quickly determine which table to access based on the sub-pixel's compensation requirements, improving productivity while maintaining manageable data structure complexity.

AI summary
Provided is a method for determining a compensation grayscale value of a display panel. The method includes searching, in a table of grayscale bit number judgment values, for a grayscale bit number judgment value corresponding to a sub-pixel to be compensated; determining a compensation grayscale value corresponding to the sub-pixel to be compensated by a first reading process if the grayscale bit number judgment value satisfies a grayscale bit number condition, and determining the compensation grayscale value corresponding to the sub-pixel to be compensated by a second reading process if the grayscale bit number judgment value does not satisfy the grayscale bit number condition.
