Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display components that use a light source unit for backlighting face challenges in miniaturization due to the need for a beam splitting unit to convert natural light into polarized light, which increases the thickness and complexity of the display component.
Innovation Solution
A display component configuration that includes a light source unit, a polarization unit to convert source light into polarized light, and a reflecting unit to convert the polarized light into reflected light on a reflective surface, allowing for reduced thickness and improved energy utilization, while enabling the display unit to adjust the reflected light for image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a beam splitting unit is used to convert natural light into polarized light, then the display function is achieved, but the thickness and complexity of the display component increases
Solution Approach 1:
The patent segments the beam splitting function into multiple reflective surfaces positioned at different locations, rather than using a single thick beam splitting unit. The light path is divided into multiple segments that reflect sequentially, achieving the same polarization conversion function while reducing overall thickness.
Solution Approach 2:
The patent changes the spatial arrangement from a single thick unit to multiple thin units distributed in a two-dimensional plane. The reflective surfaces are arranged at different positions and angles, converting the thickness problem into a planar layout problem, thereby reducing the z-direction thickness while maintaining functionality.
2Reliability
If a beam splitting unit is used to convert natural light into polarized light, then the display function is achieved, but the structural complexity increases
Solution Approach 1:
The patent merges the beam splitting function with the existing reflective surfaces in the display component. Instead of adding a separate beam splitting unit, the functionality is integrated into the reflective surfaces that are already part of the display structure, thereby reducing overall structural complexity.
Solution Approach 2:
The reflective surfaces serve dual functions: they act as both the display component's reflective elements and the beam splitting unit simultaneously. This multi-functionality eliminates the need for a separate beam splitting unit, reducing structural complexity while maintaining display functionality.
3Illumination intensity
If the emitting surface of the beam splitting unit covers the entire liquid crystal layer, then complete illumination is achieved, but miniaturization is deteriorated
Solution Approach 1:
The illumination function is segmented into multiple reflective surfaces distributed across different positions. Each surface covers only a portion of the liquid crystal layer, but collectively they provide complete coverage. This segmentation allows smaller individual components while achieving the same total illumination area.
Solution Approach 2:
The patent transitions from a single large emitting surface to multiple smaller surfaces arranged in a two-dimensional distribution pattern. This allows the same total illumination coverage to be achieved with smaller individual components, enabling miniaturization while maintaining complete illumination of the liquid crystal layer.
