Modular Display Gain Sets for Consistent Multi-Resolution Luminance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular display apparatuses exhibit varying luminance levels when displaying the same image due to differences in resolution, despite using the same peak luminance control data, leading to inconsistent image quality across combined displays.
Innovation Solution
A modular display apparatus and method that adjusts image data based on resolution-specific gain sets, identifying and applying minimum gain values to maintain consistent luminance across different resolutions by using a processor to manage power loads and luminance correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same peak luminance control data is used for display apparatuses of different resolutions, then the control process is simple, but the luminance consistency across different resolutions deteriorates
Solution Approach 1:
The patent applies parameter changes by introducing resolution-specific gain sets that adjust the peak luminance control data based on the display apparatus resolution. Different resolutions (e.g., 4K, 8K) have different gain sets stored in memory, allowing the system to optimize luminance control for each resolution level while maintaining overall luminance consistency across the modular display wall.
2Illumination intensity
If resolution-specific gain sets are applied to maintain luminance consistency, then luminance consistency improves, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing multiple gain sets in memory, each optimized for a specific resolution. The controller selects and applies the appropriate gain set based on the detected resolution before displaying content, eliminating the need for real-time calculations and reducing runtime complexity while maintaining luminance consistency.
Solution Approach 2:
The display apparatus performs self-service by automatically detecting its resolution and selecting the corresponding gain set from stored options. The system self-configures without external intervention, with the controller autonomously managing the selection and application of appropriate gain sets based on the operational resolution.
