Active Parallax Barrier Panel for Multi-Viewpoint 3D Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display apparatuses using binocular parallax have limitations in displaying a high number of viewpoints without deteriorating display resolution, particularly due to the physical attachment of lenses or barriers which interfere with 2D image display and restrict viewing angles.
Innovation Solution
A method and apparatus that utilize an active parallax barrier panel with a display panel to selectively open sub-areas during a frame interval, providing multiple viewpoint images by time-division driving the barrier panel at a frequency twice that of the display panel, allowing for increased viewpoints while maintaining resolution through a pixel and barrier structure optimized for 3D image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenses or barriers are physically attached to the display apparatus, then 3D image display is enabled, but the use of the display apparatus in displaying 2D images is interfered with
Solution Approach 1:
The barrier unit is designed to be movable rather than fixed, allowing it to switch between positions. The barrier can be moved to a first position for 3D image display and to a second position for 2D image display, enabling the display apparatus to adapt between different display modes without physical interference
Solution Approach 2:
The barrier unit is divided into multiple barrier segments that can be independently controlled. Each barrier segment can be selectively positioned to block specific portions of the display panel, allowing the system to create different viewing angles for 3D images while maintaining the ability to display 2D images when barriers are repositioned
2Adaptability or versatility
If a parallax barrier or lens arrangement is used, then a finite number of distinct viewing angles are provided, but the display resolution deteriorates
Solution Approach 1:
The barrier unit is segmented into multiple barrier segments that can be independently controlled. Each barrier segment can be selectively positioned to block specific portions of the display panel, allowing the system to create different viewing angles for 3D images while maintaining the ability to display 2D images when barriers are repositioned
Solution Approach 2:
The barrier unit is designed to be movable rather than fixed, allowing it to switch between positions. The barrier can be moved to a first position for 3D image display and to a second position for 2D image display, enabling the display apparatus to adapt between different display modes without physical interference
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
This approach enhances the number of viewpoints in 3D image display while minimizing the deterioration of display resolution, enabling more viewers to experience 3D images without compromising the quality of the 2D image display.
Implementation Method 1
The lens panel refracts a 3D image displayed on the display panel to plural viewpoints to display a 3D image
Implementation Method 2
The active parallax bather panel serves to block the observer's left eye from seeing sections of the display apparatus that display images intended for the right eye

AI summary
A display apparatus includes a display panel and an active parallax barrier panel. The display panel displays n numbers of viewpoint images on a display panel (‘n’ is natural numbers greater than 2). The active parallax barrier panel includes a plurality of barrier units. Each of the barrier units includes an opening portion and a blocking area divided into m numbers of sub-areas. The active parallax barrier panel selectively opens the m numbers of sub-areas to exit the m numbers of viewpoint images on (n×m) numbers of viewpoint positions (‘m’ is natural numbers greater than 2). Thus, an active parallax barrier panel is time-division driven to display multi-viewpoint images. Moreover, a pixel structure and a barrier structure are alerted, so that deterioration of a resolution of a 3D image may be minimized.
