Dynamic Display Area Adjustment for Viewing Angle Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses, such as LCDs and OLEDs, typically display images across their entire active area, resulting in optimal viewing angles only when the viewer is positioned specifically, leading to suboptimal viewing experiences for viewers not at this specific position.
Innovation Solution
A display method and apparatus that determine a target display area within the active area based on viewing position parameters, including vertical distance and deviation from the central axis, to adjust the size and position of the displayed image for better viewing angles across various viewer positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images are displayed across the entire active area, then the display apparatus can provide full-screen coverage, but viewers not at the specific optimal position experience suboptimal viewing angles
Solution Approach 1:
The patent implements dynamic adjustment of the display area based on real-time detection of viewer position. The display region transitions from a fixed full-screen area to a dynamically optimized area that adapts to the viewer's location, thereby maintaining optimal viewing angles across different positions. This resolves the contradiction by making the display system flexible rather than static.
Solution Approach 2:
The patent changes the parameters of the display area (position and size) based on detected viewing position parameters. By adjusting these parameters dynamically according to viewer location, the system maintains optimal viewing angles for viewers at different positions, resolving the contradiction between full-screen coverage and viewing angle quality.
2Use of energy by moving object
If the display area is reduced to a target display area based on viewing position, then power consumption is reduced by illuminating only necessary parts, but the display area coverage is limited
Solution Approach 1:
The patent applies local quality by illuminating only the specific region where viewers are located rather than the entire display area. The backlight module adjusts its illumination distribution to match the target display area, providing concentrated lighting where needed and reducing energy waste in unused regions. This resolves the contradiction between power efficiency and display coverage.
3Adaptability or versatility
If the display area is dynamically adjusted based on viewing position, then viewing angles are optimized for different positions, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with electronic control and software algorithms. Instead of physically moving display components, the system uses image processing algorithms to detect viewer position and electronically adjusts the display area parameters. This substitution of mechanical systems with electronic/intelligent systems reduces overall system complexity while maintaining adaptability.
Solution Approach 2:
The display apparatus automatically detects viewer position and adjusts the target display area without requiring manual intervention. The system performs self-adjustment based on detected viewing parameters, eliminating the need for complex user interfaces or manual calibration mechanisms. This self-service capability reduces operational complexity while maintaining high adaptability.
