Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
3D display devices currently cannot maintain a suitable 3D effect after orientation adjustment, limiting their functionality to only one posture.
Innovation Solution
A method and device that detect posture changes in 3D display devices with multi-viewpoint screens and lenticular gratings, adjusting the display orientation of 3D images to maintain the initial orientation, ensuring consistent 3D effects across different postures and viewing orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a 3D display device is configured to display a suitable 3D effect in one posture, then the 3D display quality is improved, but the device cannot display the 3D effect in another posture
Solution Approach 1:
The patent implements dynamic posture detection using sensors (accelerometers, gyroscopes) to continuously monitor device orientation changes. The system dynamically adjusts the display content and grating configuration in real-time based on detected posture, enabling the 3D display to maintain quality across multiple postures rather than being fixed for a single orientation
Solution Approach 2:
The system changes display parameters including image orientation, grating angle, and viewpoint configuration based on detected device posture. By dynamically adjusting these parameters, the display maintains optimal 3D effects whether the device is held horizontally, vertically, or at various angles
2Adaptability or versatility
If the lenticular grating is obliquely arranged to cover multiple subpixels, then multiple viewpoints are defined, but the system complexity increases
Solution Approach 1:
The lenticular grating is divided into multiple independent lenticular elements, each covering specific subpixels and defining particular viewpoints. This segmentation allows flexible configuration of viewpoints without requiring a complete redesign of the entire grating structure, managing complexity through modular design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A method for implementing 3D image display and a 3D display device are provided. The method comprises: detecting a posture change of a 3D display device, which comprises a multi-viewpoint 3D display screen comprising multiple composite pixels and a lenticular grating covering the multiple composite pixels, each composite pixel comprises multiple composite subpixels, each composite subpixel comprises multiple subpixels, and the lenticular grating is obliquely arranged to cover multiple subpixels along a first direction of the 3D display device to define multiple first posture viewpoints and cover at least two composite pixels along a second direction of the 3D display device to define at least two second posture viewpoints; and when a posture of the 3D display device changes, adjusting a display orientation of a 3D image, so that the 3D image is kept in an initial display orientation before a posture change of the 3D display device.
