Auto-Stereoscopic Display Barrier Integration for Slim Form Factor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auto-stereoscopic display devices using liquid crystal panels as barriers increase the thickness of the display, making it difficult to achieve a slim form factor while maintaining the stereoscopic effect.
Innovation Solution
A display device with a barrier comprising sub-barriers positioned directly on the surface of the display panel, covering pixel areas to separate left-eye and right-eye images, allowing for a slim design while enabling stereoscopic image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid crystal panel is used as the barrier to achieve stereoscopic effect, then the stereoscopic effect is improved, but the thickness of the display panel increases
Solution Approach 1:
The patent extracts the barrier function from a separate liquid crystal panel and integrates it directly into the display panel structure. The barrier is formed as a patterned layer on the display panel surface, eliminating the need for an additional liquid crystal panel while maintaining the stereoscopic effect through selective light blocking in transparent and opaque regions.
Solution Approach 2:
The patent merges the barrier and display panel into a single integrated structure. The barrier is positioned on the surface of the display panel, combining the functions of light emission/display and light blocking/barrier in one component, thereby reducing overall thickness while preserving stereoscopic capability.
2Reliability
If a barrier is added to separate left-eye and right-eye images, then stereoscopic image recognition is improved, but the display panel becomes thicker
Solution Approach 1:
The patent transitions from a three-dimensional stacked structure (separate barrier panel behind the display) to a two-dimensional surface integration (barrier patterned on the display panel surface). This dimensional change allows the barrier to function without adding significant thickness, as it operates in the planar domain rather than requiring axial separation.
3Manufacturing precision
If sub-barriers are positioned to cover pixel areas, then image separation quality is improved, but manufacturing complexity increases
Solution Approach 1:
The barrier is segmented into multiple sub-barriers, each covering specific pixel areas corresponding to left-eye or right-eye images. This segmentation enables precise control over which pixels are visible to which eye, improving image separation quality while allowing each sub-barrier to be relatively simple in structure.
Solution Approach 2:
Different regions of the barrier have different properties - some regions are transparent to allow light transmission for visible pixels, while other regions are opaque to block light for hidden pixels. This local differentiation of properties enables precise image separation without requiring the entire barrier to be complex.
