Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double-faced display devices cannot simultaneously display images on both sides, limiting their application in public places where dual-sided information dissemination is required.
Innovation Solution
A double-faced display panel design featuring an array substrate and an opposed substrate with a trans-reflective layer comprising alternately arranged reflection and transmission regions, allowing both faces to display images simultaneously by controlling the states of the reflection and transmission regions using a PDLC structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reflective polarizer is used between the second polarizer and the liquid crystal layer, then one face can display in reflection mode, but both faces cannot display simultaneously
Solution Approach 1:
The reflective polarizer is segmented into reflection regions and transmission regions, allowing different areas to perform different functions (reflection or transmission) simultaneously, enabling both faces to display at the same time
Solution Approach 2:
Different regions of the reflective polarizer are assigned different optical properties (reflection or transmission) based on local requirements, with reflection regions for one face and transmission regions for the other face
2Adaptability or versatility
If the liquid crystal molecules are in horizontal state, then one face displays in transmission mode, but the other face cannot display in reflection mode at the same time
Solution Approach 1:
The reflective polarizer is divided into reflection regions and transmission regions, allowing simultaneous reflection mode display on one face and transmission mode display on the other face
Solution Approach 2:
The solution moves from a single-state liquid crystal layer to a multi-functional reflective polarizer with spatially differentiated regions, adding a spatial dimension to functional differentiation
