Polarized LED Pixel Layout for Combined 2D and 3D Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic display systems face limitations in providing a wide range of 3D viewing experiences beyond traditional movie theater environments, such as billboards and large outdoor displays, due to the need for custom controllers and LEDs that process two pixels at once, leading to viewer discomfort and limited advancements in 3D viewing outside these settings.
Innovation Solution
The implementation of an array of multiple polarizing light emitting packages (MLEPs) with sectors containing light emitting elements and polarizers, positioned to create a 3D image when viewed through polarizing glasses, allowing for standard 2D functionality while enabling 3D content display without the need for special controllers, and maintaining a similar form factor and functionality to standard 2D LEDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom controllers and LEDs that process two pixels at once are used, then 3D viewing capability is achieved, but device complexity increases and viewer comfort deteriorates
Solution Approach 1:
The patent divides each physical LED pixel into multiple virtual pixels through software processing. Instead of using complex custom hardware LEDs that physically contain two pixels, the system uses standard single-pixel LEDs and creates multiple virtual pixels by segmenting the color space and processing channels separately. This allows 3D functionality without increasing physical device complexity.
Solution Approach 2:
The patent replaces the mechanical/hardware approach of custom dual-pixel LEDs with a software-based solution. The controller processes image content and generates separate color channels for left and right eyes through software algorithms, eliminating the need for custom hardware controllers and specialized dual-pixel LEDs.
2Adaptability or versatility
If color-coded views are projected for stereoscopic display, then 3D viewing is enabled, but viewer comfort deteriorates due to headaches
Solution Approach 1:
The patent changes the parameter of light polarization from color-based separation to polarization-based separation. Instead of using different colors (RGB channels) to separate left and right views, the system uses polarized filters with specific orientation angles. This parameter change eliminates color distortion and viewer discomfort while maintaining 3D capability.
3Device complexity
If standard single LED arrangements are used, then device simplicity is maintained, but 3D viewing capability is lost
Solution Approach 1:
The patent makes standard single-pixel LEDs multi-functional by enabling them to display both 2D and 3D content. The same physical LED infrastructure can present conventional 2D images or switch to stereoscopic 3D mode with appropriate polarized filters and software processing, eliminating the need for separate 3D-specific hardware while maintaining 3D capability.

AI summary
The present invention provides systems, and methods for manufacturing an array of multiple polarizing light emitting packages (MLEPs), wherein each of MLEPs includes a first left sector, a second left sector, a first right sector, and a second right sector; and each sector of the MLEPs includes at least a first light emitting element and a polarizer; and the MLEPs are positioned and oriented within the array such that when the array is viewed through glasses with corresponding polarizing lenses, a viewer perceives an image displayed by the array as a three-dimensional image. Each sector of the MLEPs is separated by a distance, and each polarizer is separated from others via an opaque, separator wall.
