Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses struggle to provide high-resolution three-dimensional images without optical crosstalk, which reduces image resolution and luminance.
Innovation Solution
A display apparatus with a light source unit and an image conversion unit, where the light source unit consists of spaced-apart light emitting groups with micro-LED pixels, and the image conversion unit uses a lens unit or barrier to separate and adjust light paths for each eye, reducing crosstalk and increasing luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light paths are separated to display three-dimensional images, then stereoscopic effect is achieved, but optical crosstalk occurs and image resolution is reduced
Solution Approach 1:
The display panel is divided into multiple light emitting groups with different separation distances. Specifically, a first light emitting group has a first separation distance between adjacent pixels, while a second light emitting group has a second separation distance that is greater than the first separation distance. This segmentation allows different regions to serve different functions: the first group provides continuous image coverage while the second group reduces optical crosstalk for stereoscopic display.
Solution Approach 2:
Different separation distances are applied to different light emitting groups based on their specific functional requirements. The first light emitting group uses a smaller separation distance optimized for general image display and luminance, while the second light emitting group uses a larger separation distance optimized for reducing optical crosstalk during three-dimensional image display. This local quality differentiation resolves the contradiction between maintaining resolution and enabling stereoscopic effect.
2Adaptability or versatility
If light is blocked to separate paths for each eye, then three-dimensional image is achieved, but luminance is reduced
Solution Approach 1:
The display is segmented into multiple light emitting groups with different separation distances. The first light emitting group with smaller separation maintains higher luminance for general viewing, while the second light emitting group with larger separation reduces optical crosstalk. This segmentation allows the system to achieve three-dimensional display capability without uniformly reducing luminance across the entire display.
Solution Approach 2:
The separation distance parameter is changed between different light emitting groups. By varying this geometric parameter, the patent optimizes both luminance (smaller separation) and crosstalk reduction (larger separation) in different regions, thereby achieving three-dimensional display without significant luminance loss.
3Area of stationary object
If pixels are consecutively disposed without separation, then screen area is maximized, but optical crosstalk increases
Solution Approach 1:
The display panel is segmented into multiple light emitting groups with different separation distances. The first light emitting group has adjacent pixels with minimal separation to maximize screen area utilization, while the second light emitting group has increased separation to reduce optical crosstalk. This segmentation allows the system to simultaneously achieve high screen area utilization and reduced optical crosstalk.
Solution Approach 2:
Different separation characteristics are applied to different light emitting groups based on local requirements. The first group prioritizes screen area maximization with minimal pixel separation, while the second group prioritizes crosstalk reduction with larger separation. This local differentiation resolves the contradiction between screen area and optical crosstalk.
