Stereoscopic Display Barrier Panel Trigger Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stereoscopic display devices face image quality degradation and visibility of bright or dark lines when the viewing distance of a viewer is outside the proper range due to changes in the size of blocking and transmitting regions of the barrier panel.
Innovation Solution
A stereoscopic display device with a barrier panel featuring trigger regions with intermediate gray values between barrier regions, where the number of channels in trigger regions is half that of barrier regions, and these regions are disposed symmetrically to adjust the size and position of transmitting and blocking regions based on viewing distance to prevent image quality degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the barrier panel moves the blocking regions and transmitting regions to accommodate viewers outside the proper viewing distance range, then the stereoscopic image can be provided to a wider range of viewers, but the size of blocking and transmitting regions changes causing image quality degradation and visible bright or dark lines
Solution Approach 1:
The barrier panel is divided into multiple channels with blocking regions and transmitting regions. By individually controlling the voltage applied to each channel, the panel can adjust the position and size of these regions to maintain image quality across different viewing distances, preventing the degradation and visible artifacts that would otherwise occur.
Solution Approach 2:
The barrier panel dynamically adjusts the voltage applied to its channels based on the viewer's position. This dynamic control allows the blocking and transmitting regions to adapt their configuration in real-time, maintaining optimal image quality whether the viewer is within or outside the standard viewing distance range.
2Adaptability or versatility
If the barrier panel adjusts the voltage to move blocking and transmitting regions for viewers at non-standard distances, then stereoscopic images can be provided to these viewers, but bright lines and dark lines become visible due to region size changes
Solution Approach 1:
Different regions of the barrier panel are assigned different voltage levels to create varying optical properties. By applying intermediate gray values to specific channels, the panel creates smooth transitions between blocking and transmitting regions, eliminating the abrupt boundaries that cause visible bright and dark lines while maintaining adaptability to different viewing distances.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures that the stereoscopic image quality is maintained for viewers at non-standard distances by blurring the boundaries between trigger regions, preventing the visibility of bright or dark lines and enhancing the viewing experience by adjusting the focus accordingly.
Implementation Method 1
The barrier panel may form a path difference of light by individually or region-by-region adjusting voltage applied to the channels disposed at regular intervals. The barrier panel may include blocking regions and transmitting regions formed by the applied voltage.
Implementation Method 2
The barrier panel may include a liquid crystal disposed between a lower barrier substrate and an upper barrier substrate.

AI summary
A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.
