Solution Overview
Problem
Conventional three-dimensional display apparatuses lack effective techniques for appropriately displaying three-dimensional images to the left and right eyes, limiting their convenience and effectiveness.
Innovation Solution
A three-dimensional display system comprising a display apparatus with subpixels arranged in a grid, a barrier with light shielding and transmitting regions, and a detection apparatus to adjust the display boundaries based on the observation distance, ensuring that the left-eye and right-eye images are correctly directed to the user's eyes, enhancing the display of three-dimensional images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed display boundary is used to separate left-eye and right-eye images, then the structure is simple, but the display quality deteriorates when observation distance changes due to crosstalk
Solution Approach 1:
The display boundary is made dynamic by adjusting its position based on the detected observation distance. The controller modifies the phase of the display boundary periodically in the horizontal direction according to the observed distance, allowing the system to adapt to different viewing conditions and maintain high display quality without fixed structural complexity
Solution Approach 2:
The phase parameter of the display boundary is changed based on the observation distance detected by the detection apparatus. By periodically adjusting the phase position of the display boundary in the horizontal direction, the system optimizes image separation for different viewing distances, reducing crosstalk while maintaining system simplicity
2Reliability
If the display boundary phase is adjusted for different observation distances, then crosstalk is reduced and display quality improves, but the system complexity increases due to detection and control mechanisms
Solution Approach 1:
The detection apparatus provides feedback on the observation distance to the controller, which then adjusts the display boundary phase accordingly. This feedback loop enables the system to automatically adapt to different viewing conditions, maintaining high image separation accuracy while using a relatively simple control mechanism
Solution Approach 2:
The system uses the detection apparatus to automatically determine the observation distance and adjust the display boundary without requiring manual intervention. The controller self-adjusts the phase of the display boundary based on detected conditions, reducing the need for complex external control systems

Function Achieved in This Case
This solution allows for improved convenience in displaying three-dimensional images by accurately directing the images to the user's eyes, reducing crosstalk and enhancing the overall display quality.
Implementation Method 1
The barrier has a light shielding region that shields the left-eye image and the right-eye image, and a light transmitting region that causes at least part of the left-eye image to reach a left eye of a user and at least part of the right-eye image to reach a right eye of a user

AI summary
A three-dimensional display apparatus comprises a display panel (display element) and a parallax barrier (optical element). The display panel displays a left-eye image and a right-eye image respectively in first subpixels and second subpixels. The parallax barrier transmits at least part of the left-eye image toward the left eye, and at least part of the right-eye image toward the right eye. A first certain number of the first subpixels and of the second subpixels are each successively arranged in each column. A region in which the first subpixels are arranged and a region in which the second subpixels are arranged are displaced from each other by a second certain number between two adjacent columns. The first certain number is greater than the second certain number and is not a multiple of the second certain number.
