Foldable Display Gamma Correction via Posture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for improving display quality by adjusting viewing angles are ineffective for foldable electronic devices with multiple display panels, as they fail to account for the varying line of sight and angles between multiple display panels, leading to suboptimal visual fields.
Innovation Solution
An information display apparatus with multiple display units, a detection unit to monitor posture angles, and a gamma storage unit to store correction values, enabling the display control unit to perform gamma correction based on detected angles, ensuring optimal visual fields across all display panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional single-panel viewing angle adjustment technique is applied, then display quality is improved for one panel, but display quality deteriorates for multiple panels due to varying lines of sight
Solution Approach 1:
The patent applies dynamics by making the gamma correction values adjustable based on real-time detection of display panel angles. The system transitions from static, fixed gamma correction to dynamic, angle-dependent gamma correction that adapts to different viewing conditions for each panel independently
Solution Approach 2:
The patent changes the parameter of gamma correction values based on detected posture angles of each display panel. By storing multiple gamma correction values corresponding to different angles and selecting appropriate values dynamically, the system optimizes display quality for each panel's specific viewing condition
2Manufacturing precision
If fixed gamma correction values are used for all display panels, then device complexity is reduced, but display quality deteriorates due to inability to account for varying viewing angles
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple gamma correction values in memory corresponding to different posture angles before actual use. This allows the system to quickly retrieve and apply appropriate correction values without complex real-time calculations, reducing computational complexity while maintaining high display quality
Solution Approach 2:
The patent implements feedback by detecting the actual posture angles of display panels and using this information to select appropriate gamma correction values. This closed-loop approach ensures optimal display quality while keeping the control mechanism relatively simple through angle-based selection
