Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emissive displays rely on lenticular lenses or specialized eyewear to produce controlled-angle and stereoscopic images, which have limited viewing angles, reduced clarity, and inconvenient use requirements, making them impractical for broad consumer and application use.
Innovation Solution
The development of controlled-angle emissive displays featuring angular arrays of emissive elements, such as LEDs or OLEDs, arranged in a planar base structure with angled sides, allowing for selectable viewing angles without the need for lenticular lenses or specialized eyewear, enhancing viewing angles and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenticular lenses or specialized eyewear are used to produce controlled-angle display, then stereoscopic images can be achieved, but viewing angle is limited and visual clarity is reduced
Solution Approach 1:
The display is divided into multiple angular arrays of emissive elements, each array oriented at different angles to direct light to different viewing zones. This segmentation allows different portions of the display to serve different viewing angles simultaneously, achieving both broad adaptability and maintained clarity in each zone.
Solution Approach 2:
Different regions of the display have locally optimized emissive element orientations. Each angular array is configured with specific orientations tailored to its intended viewing zone, providing locally optimized visual quality while collectively achieving broad viewing angle coverage across the entire display.
2Adaptability or versatility
If lenticular lenses are used for controlled-angle display, then stereoscopic images can be produced, but the display requires specialized eyewear that adds cost and inconvenience
Solution Approach 1:
The patent extracts and eliminates the need for external optical components (lenticular lenses and specialized eyewear) by integrating the light-directing function directly into the display structure through angular arrays of emissive elements. This removes the harmful dependency on additional devices while preserving the controlled-angle display capability.
Solution Approach 2:
The display structure itself performs the function of directing light to different viewing angles through its angular array configuration. The emissive elements are inherently oriented to self-direct their light output, eliminating the need for separate optical components or eyewear to achieve controlled-angle display.
3Ease of operation
If conventional emissive displays are used, then simple structure is maintained, but viewing angle is limited and clarity is reduced at non-optimal angles
Solution Approach 1:
The display provides dynamic viewing experience by configuring emissive elements at multiple angles to actively direct light to different viewing zones. This dynamic light direction maintains image clarity across various viewing positions, allowing the display to adapt to different viewing angles without sacrificing visual quality.
