Flexible Auto-Stereoscopic Display Bending Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible auto-stereoscopic displays face challenges in maintaining a three-dimensional image effect when bent, as the parallax barrier arrangement and pixel characteristics are not adjusted accordingly, leading to a degradation or loss of the stereoscopic effect for viewers positioned outside the 'sweet spots'.
Innovation Solution
An apparatus comprising a processor and memory that detects bending of the flexible display and adjusts the parallax barrier arrangement, pixel brightness, and hue to compensate for the bending, ensuring the stereoscopic effect is maintained by repositioning opaque regions and adjusting light distribution to prevent image content overlap between viewer's eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display is bent, then the display can be adapted to different viewing positions and surfaces, but the parallax barrier arrangement and pixel characteristics are not adjusted accordingly, leading to degradation or loss of the stereoscopic effect
Solution Approach 1:
The patent implements dynamic adjustment of the parallax barrier arrangement and pixel characteristics based on detected bending state. The system transitions from a static configuration to a dynamic one where parameters are continuously adapted to maintain stereoscopic functionality despite physical deformation of the flexible display
Solution Approach 2:
The system employs feedback through a bending detection unit that monitors the display's physical state and provides information to the controller. This closed-loop control enables the system to sense bending and automatically compensate by adjusting parallax barrier and pixel parameters, ensuring the stereoscopic effect is maintained across different bending states
2Reliability
If the parallax barrier arrangement is adjusted to compensate for bending, then the stereoscopic effect is maintained, but the device complexity increases due to additional sensing and control requirements
Solution Approach 1:
The controller performs multiple functions: it manages the display output, processes bending detection data, calculates compensation parameters, and controls both the parallax barrier arrangement and pixel characteristics. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while maintaining stereoscopic reliability
3Ease of operation
If the position of the image on the flexible display is moved based on bending inputs, then the image remains viewable from correct positions, but the manufacturing precision requirements increase for the bending measurement and image positioning systems
Solution Approach 1:
The system dynamically changes display parameters including image position, parallax barrier configuration, and pixel characteristics based on bending detection. By adjusting multiple parameters in coordination rather than relying solely on high-precision mechanical positioning, the system achieves ease of operation while managing manufacturing precision requirements
