Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing naked-eye 3D display devices are thick due to separate lens structures and suffer from significant light reflection, which affects their display quality and thickness, hindering the development of ultra-thin display devices.
Innovation Solution
An integrated display panel with a transparent display layer, a polarizing layer, and a liquid crystal lens film layer, where the polarizing film absorbs ambient light and the liquid crystal lens layer transmits left- and right-eye images to the respective eyes, reducing thickness and light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate lens structure is installed on the display panel to achieve naked-eye 3D display, then the 3D display function is realized, but the thickness of the entire display device increases
Solution Approach 1:
The patent integrates the lens structure directly into the display panel by forming a lens-shaped cavity in the encapsulation layer and filling it with liquid crystal material. This merging of the lens structure with the display panel eliminates the need for separate lens components, thereby reducing overall device thickness while maintaining naked-eye 3D display functionality.
Solution Approach 2:
The lens structure is nested within the encapsulation layer of the display panel. The lens-shaped cavity is formed by removing material from the encapsulation layer, and the liquid crystal filling material is injected into this nested cavity. This nesting approach allows the lens function to be embedded within the existing display structure without adding external thickness.
2Adaptability or versatility
If a separate lens structure is installed on the display panel, then the 3D display function is achieved, but light reflection becomes serious and affects display effect
Solution Approach 1:
The patent changes the optical parameters of the lens structure by using liquid crystal material with specific refractive index properties. The liquid crystal material's optical anisotropy allows control over light transmission and reflection characteristics, reducing harmful light reflection while maintaining the 3D display effect through appropriate alignment layer treatment and optical axis orientation.
3Adaptability or versatility
If traditional binocular 3D display technology is used, then 3D effect can be experienced, but glasses or helmets are required which reduces immersion
Solution Approach 1:
By merging the lens structure with the display panel itself, the system eliminates the need for external optical components that require user accessories. The integrated design allows direct viewing of the 3D image without glasses or helmets, significantly improving ease of operation and viewer immersion while maintaining the binocular 3D display effect.
