Solution Overview
Problem
Conventional 3D image display devices using active retarder panels require high-temperature processes and glass substrates, leading to increased weight, volume, and fabrication costs, which hinder the development of lightweight and ultrathin display devices.
Innovation Solution
A flexible active retarder panel is fabricated using a polymer layer with light alignment and light-curing characteristics, where LC droplets are dispersed, allowing for a low-temperature process and eliminating the need for glass substrates, with transparent electrodes formed on flexible films to control light phase shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass substrates and high-temperature processes are used to fabricate active retarder panels, then the structural stability and alignment layer formation are improved, but the weight, volume, and fabrication costs increase
Solution Approach 1:
The patent changes the temperature parameter from high-temperature (conventional glass substrate process) to low-temperature (flexible substrate process), enabling the use of flexible substrates instead of rigid glass substrates. This parameter change reduces the weight and volume of the panel while maintaining the functional requirements of the active retarder through alternative alignment layer formation methods compatible with low-temperature processing.
Solution Approach 2:
The patent replaces expensive glass substrates with cheaper flexible substrates that can be processed at lower temperatures. The flexible substrate approach uses more economical materials and processing methods, reducing fabrication costs while achieving the necessary structural stability through the flexible substrate's inherent properties and the low-temperature alignment layer formation process.

3Manufacturing precision
If conventional active retarder panels with multiple glass substrates are used, then the alignment layer formation is improved, but the device thickness increases
Solution Approach 1:
The patent changes the temperature parameter to low-temperature processing, which enables the formation of alignment layers on flexible substrates without requiring high-temperature processes. This parameter change allows for a more compact structure with reduced thickness while maintaining proper alignment layer formation through low-temperature compatible methods.
Solution Approach 2:
The patent uses flexible substrates instead of multiple glass substrates, reducing the overall device thickness. The flexible substrate approach eliminates the need for thick glass layers while maintaining alignment layer formation through low-temperature processing methods, resulting in a thinner overall panel structure.
