Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional naked-eye 3D display devices require complex laminating processes, high-precision devices, and multiple substrates, leading to increased substrate usage, complex manufacturing, and poor 3D display effects at farther viewing distances.
Innovation Solution
A naked-eye 3D display device is designed with a two-dimensional display panel, a third substrate, and two liquid crystal layers, where electrodes apply an electric field to form a light splitting device, reducing substrate usage and eliminating the need for laminating, thus simplifying the process and improving yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional laminating processes are used with multiple substrates, then the structural integrity is maintained, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the 2D display panel and 3D light splitting device into a single integrated structure where the second substrate serves as the lower substrate for both components. The electrodes are disposed on the same lower substrate, and a single liquid crystal layer serves both the 2D display and 3D light splitting functions, eliminating the need for separate laminating processes and reducing overall device complexity while maintaining structural integrity
Solution Approach 2:
The lower substrate (second substrate) performs multiple functions: it serves as the upper substrate for the 2D display panel and the lower substrate for the 3D light splitting device simultaneously. The liquid crystal layer and electrodes are configured to provide both 2D display and 3D light splitting capabilities, reducing the total number of substrates needed from four to three
2Quantity of substance
If multiple substrates are used in conventional designs, then the manufacturing process is robust, but the substrate usage amount increases and placing height increases
Solution Approach 1:
The patent combines multiple functions into fewer substrates. The second substrate (lower substrate) is shared between the 2D display panel and the 3D light splitting device. The liquid crystal layer is configured to serve both functions simultaneously. This merging reduces the total substrate count from four separate substrates to three substrates, decreasing material usage and simplifying the manufacturing process by eliminating one lamination step
3Length of stationary object
If conventional light splitting devices are used, then the 3D display function is achieved, but the placing height increases and viewing distance must be increased
Solution Approach 1:
The patent merges the 2D display panel and 3D light splitting device into a single integrated structure with shared substrates and liquid crystal layer. This integration significantly reduces the placing height by eliminating the need for separate stacked structures. The reduced placing height enables effective 3D display at closer viewing distances, making the device suitable for mobile phone applications where compact form factor is critical
