Light-Splitting Structures for Continuous 3D Display Emission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display technologies face challenges in achieving continuous light emission and viewing angles due to gaps between sub-pixels in pixel islands, resulting in 'black regions' and affected viewing effects.
Innovation Solution
A display apparatus with a display panel comprising pixel islands arranged in rows and columns, each with multiple sub-pixels, and a light-splitting component with continuously arranged light-splitting structures. The sub-pixels are arranged in a staggered complementary mode relative to the light-splitting structures, ensuring continuous light emission and viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sub-pixels are arranged with intervals in pixel islands, then manufacturing is simplified, but continuous light emission is compromised causing black regions
Solution Approach 1:
The patent transitions from two-dimensional planar arrangement of sub-pixels to three-dimensional spatial arrangement by introducing light-splitting structures that direct light at different angles. This dimensional change allows sub-pixels to be staggered complementary to light-splitting structures, filling gaps in the light emission pattern and eliminating black regions while maintaining simple sub-pixel arrangement.
Solution Approach 2:
Light-splitting structures serve as intermediaries between sub-pixels and the viewing space. These structures receive light from staggered sub-pixels and split/direct it to fill gaps, transforming the discontinuous light emission from intervalled sub-pixels into continuous light emission in the viewing direction.
2Device complexity
If sub-pixels are arranged in intervals, then device complexity is reduced, but viewing angle continuity is affected
Solution Approach 1:
The patent uses light-splitting structures to redirect light from staggered sub-pixels into multiple angular directions. This creates continuous viewing angles across different directions without requiring complex overlapping sub-pixel arrangements, thus reducing device complexity while improving viewing angle adaptability.
Solution Approach 2:
The light emission function is segmented between sub-pixels and light-splitting structures. Sub-pixels emit light in their respective directions, and light-splitting structures segment and redirect this light to fill angular gaps, achieving continuous viewing angles through functional segmentation rather than spatial overlap of sub-pixels.
3Illumination intensity
If staggered complementary arrangement is used, then light emission continuity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes geometric parameters of the staggered arrangement, specifically setting the offset distance between sub-pixels and light-splitting structures to specific ranges (e.g., 0.05-0.15 times the pitch). This parameter optimization ensures effective light splitting and gap filling while maintaining relaxed manufacturing tolerances.
