3D Display Screen Alignment via Dynamic Shift Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional video display devices face challenges in adjusting screen irregularities, particularly when the positional relationship between mirrors and the screen is not appropriate, leading to deviations in the displayed video, especially when used with varying smartphone models and jackets, where automatic adjustment is difficult due to separate state information requirements.
Innovation Solution
A three-dimensional video display device with a mirror device that includes a processor, storage unit, and input unit, allowing users to manually adjust the screen by shifting or resizing it through specific indication marks and buttons to align with the mirror positions, ensuring proper display alignment and format maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mirror device is mounted in a smartphone with a jacket, then the three-dimensional video display function is achieved, but the positional relationship between mirrors and screen may be deviated causing video position deviation
Solution Approach 1:
The patent implements dynamic screen adjustment by allowing the display screen to be shifted forward or backward in the depth direction based on user input. This dynamic positioning enables the system to adapt to different jacket thicknesses and smartphone models, resolving the contradiction between versatility and positional precision by making the screen position adjustable rather than fixed
Solution Approach 2:
The system changes the positional parameter of the display screen in the depth direction to compensate for variations in jacket thickness and device configuration. By adjusting the screen's Z-position, the virtual image generating regions can be realigned with the mirrors regardless of the physical configuration variations
2Adaptability or versatility
If the screen size varies depending on smartphone models, then the device can be used with different smartphone models, but the virtual image generating regions may not match the mirror positions
Solution Approach 1:
The patent employs dynamic adjustment of the display screen position in the depth direction to accommodate different smartphone models and screen sizes. This allows the system to achieve proper alignment between virtual image generating regions and mirrors for each specific device configuration
Solution Approach 2:
The system performs preliminary screen positioning adjustments before displaying the three-dimensional video. By pre-adjusting the screen position based on the specific smartphone model and jacket configuration, the system ensures that the virtual image generating regions are correctly aligned with the mirrors from the start
3Extent of automation
If automatic adjustment is implemented to read screen size information, then the adjustment process is automated, but it cannot detect jacket thickness which is separate state information
Solution Approach 1:
The patent implements a self-service adjustment mechanism where the user manually adjusts the screen position by manipulating input unit buttons while observing the display. This eliminates the need for complex automatic detection systems that would need to sense jacket thickness, allowing the system to adapt to any configuration without additional sensors or detection mechanisms

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective adjustment of screen irregularities by allowing users to manually correct deviations and resize the display, ensuring a proper three-dimensional video presentation across different devices and jackets, expanding the applicability of three-dimensional display technology.
Implementation Method 1
a mirror device 80 which includes a plurality of mirrors 81 to 83 that are parallel to each other and reflects a video displayed on a display screen 71 of the video display device 70 from the plurality of mirrors 81 to 83 to display the video as a three-dimensional video

AI summary
An adjusting screen with a predetermined format including a specific indication mark which is used to correct the display irregularity of the screen in a relationship between a plurality of mirrors and regions of the screen with a predetermined format is generated to be displayed on a display screen. In accordance with a shift input instruction that moves the screen which is displayed on the display screen in a forward or backward direction as seen from a user, the screen shift control is performed to control the adjusting screen including a specific indication mark to be moved forward or backward by a predetermined amount to be displayed on the display screen. In a state where the screen is moved by a predetermined amount by the screen shift control (in a state where the screen deviation is corrected), a video is disposed in the plurality of regions to generate an adjusting screen with a format to be displayed on the display screen and the displayed video is reflected from the plurality of mirrors to be displayed as a three-dimensional video.
