Display Drive Assembly Fusing Gamma And White Balance Compensation Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional TFT-LCD display devices face inefficiencies in gamma and white balance adjustments due to the need for separate tables for each panel type, leading to increased management costs and potential mismatches, which affect brightness and chromaticity.
Innovation Solution
A display device with a drive assembly that includes a fusion module to merge digital gamma and white balance compensation tables, allowing for direct compensation of display panels without storing multiple tables, thus avoiding mismatches and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple white balance tables are stored for different panel types, then white balance adjustment coverage is improved, but machine management costs and device complexity increase
Solution Approach 1:
The patent combines multiple white balance tables for different panel types into a single unified table structure. Instead of storing separate tables for different panel types, the system uses one comprehensive white balance table that can accommodate all panel types, thereby reducing machine management costs and device complexity while maintaining full adaptability.
Solution Approach 2:
The white balance table is designed with universal applicability to serve multiple panel types simultaneously. The table structure incorporates panel type identification and corresponding white balance parameters for various panel types (such as TN, VA, IPS) within a single unified framework, enabling one table to perform the function of multiple specialized tables.
2Measurement precision
If separate white balance tables are used for different panel types, then measurement precision is improved, but productivity decreases due to increased management overhead
Solution Approach 1:
The patent merges multiple specialized white balance tables into a single unified table that maintains the precision of individual tables. By consolidating the tables while preserving the specific white balance parameters for each panel type within the unified structure, the system achieves both measurement precision and improved productivity through reduced management overhead.
3Manufacturing precision
If multiple compensation tables are stored externally, then compensation accuracy is improved, but mismatch errors between panels and tables occur
Solution Approach 1:
The unified white balance table is designed to be universally applicable to all panel types while maintaining type-specific accuracy. The table includes identification mechanisms that match panel types with their corresponding white balance parameters, ensuring that the correct compensation data is applied to each panel type without mismatch errors.
Solution Approach 2:
The system introduces a panel type identification mechanism as an intermediary between the panel and the white balance table. This intermediary automatically identifies the panel type and selects the appropriate white balance parameters from the unified table, eliminating manual matching errors and ensuring reliable correspondence between panels and their compensation data.

AI summary
Display devices are provided. The display device includes a display panel including subpixels and a drive assembly configured to transmit data signals to the display panel. The drive assembly includes a first storage module, a second storage module, and a fusion module. A first compensation table including first grayscale data corresponding to the subpixels is stored in the first storage module. A second compensation table including second grayscale data corresponding to the first grayscale data is stored in the second storage module. The fusion module is configured to call the first compensation table and the second compensation table, calculate target grayscale data corresponding to the first grayscale data according to the second grayscale data, and compensate the display panel according to a third compensation table merged by the target grayscale data and the first grayscale data.
