Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices are thick due to multiple layered structures, including a polarizer and polarization analyzer, which hinders the design of thinner devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If separate polarizer and polarization analyzer layers are used, then display quality is maintained, but device thickness increases
Solution Approach 1:
The patent combines the polarizer and polarization analyzer into a single integrated layer structure. This common layer performs both polarization functions simultaneously, eliminating the need for separate polarizer and analyzer layers, thereby reducing the overall device thickness while maintaining display quality
Solution Approach 2:
The common layer is designed to serve multiple functions: it acts as both the polarizer and the polarization analyzer. This multi-functional design reduces the number of components needed in the display device, directly addressing the thickness issue while preserving the necessary optical functions
2Ease of manufacture
If multiple layered structures are used, then display function is complete, but manufacturing complexity increases
Solution Approach 1:
By merging the polarizer and polarization analyzer into one common layer, the patent reduces the number of manufacturing steps and assembly operations required. This integration simplifies the manufacturing process while maintaining the complete display functionality
Solution Approach 2:
The patent extracts and eliminates redundant layers from the traditional multi-layer structure. By removing unnecessary separate polarizer and analyzer layers, the design achieves simpler manufacturing while preserving essential display functions

Data Source
AI summary
A display panel and a display device are disclosed. The display panel includes an upper substrate (1) and a lower substrate (2) that are disposed opposite to each other; a liquid crystal layer (5) provided between the upper substrate (1) and the lower substrate (2); and a common electrode (3) provided on a side of the liquid crystal layer (5). The common electrode (3) has a wire gating polarizing structure that forms an polarization analyzer structure or a polarizer structure. Upon the common electrode (3) being applied for polarizing the light or analysis of light polarization, a polarizer or a polarization analyzer can be omitted in the display panel, which can reduce numbers of layered structures in the display panel and hence reduce a thickness of the display device.
