Movable Barrier Display Panel Control for 3D Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auto-stereoscopic 3D stereoscopic image display apparatuses suffer from crosstalk due to overlapping left and right eye images, degrading display quality as they are not accurately aligned with the user's position, leading to incorrect image viewing by the eyes.
Innovation Solution
A method and apparatus that control the movement of a display panel based on user position data, using a barrier part with transmittance and block cells to ensure that left and right eye images are correctly viewed by matching the user's position with predetermined set areas, thereby preventing crosstalk by adjusting the panel's position or orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a barrier type auto-stereoscopic display is used to eliminate the need for 3D glasses, then the ease of operation is improved, but crosstalk occurs due to misalignment between left and right eye images, degrading display quality
Solution Approach 1:
The display panel is made movable in the vertical direction, allowing dynamic adjustment of the barrier part's position. A driving unit changes the position of the barrier part according to user position information, enabling the system to adapt to different viewing positions and maintain proper alignment between left and right eye images, thereby eliminating crosstalk while preserving ease of operation.
2Device complexity
If the display panel is fixed in place, then the device complexity is reduced, but the user position cannot be adjusted, causing image overlap and crosstalk
Solution Approach 1:
The display panel transitions from a fixed structure to a dynamic structure with adjustable vertical position. The driving unit enables the barrier part to move to different positions based on detected user location, ensuring reliable image separation and preventing crosstalk, while the overall system remains relatively simple in implementation.
3Manufacturing precision
If the barrier part position is adjusted to match user position, then the display quality is improved by preventing crosstalk, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The system incorporates a feedback mechanism where user position information is detected and used to control the driving unit's adjustment of the barrier part position. This closed-loop control ensures the barrier part is always positioned correctly relative to the user's eyes, maintaining high display quality while using a relatively simple control architecture.
Solution Approach 2:
The system automatically adjusts the barrier part position based on detected user location without requiring manual intervention. The driving unit self-regulates the barrier part's vertical position according to the user's position information, eliminating the need for complex manual adjustment mechanisms while maintaining optimal display quality.

AI summary
A display panel driving apparatus includes a user position data output part and a move control part. The user position data output part receives user image data and outputs user position data based on the user image data. The user image data is generated by photographing a user. The user position data is generated by mapping a position of the user to a display panel. The move control part compares a plurality of set area data with the user position data and outputs a move control signal based on the comparison of the user position data and the set area data. The set area data is set to the display panel. The move control signal controls a movement of the display panel.
