Solution Overview
Problem
Existing liquid crystal display panels face issues such as uneven brightness, bright spots, and pixel failure due to impurity particles affecting the electrode structure during manufacturing, leading to reduced yield and product quality.
Innovation Solution
The design of an electrode structure with a first electrode portion and a second electrode portion featuring semi-open slits allows liquid crystal molecules to deflect at the slit openings, improving light efficiency and overcoming limitations of related technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the electrode structure uses a closed slit design, then the structural integrity is improved, but the light efficiency deteriorates
Solution Approach 1:
The electrode structure is divided into multiple electrode portions with slits between them, allowing the structure to maintain integrity while creating openings for light transmission. The slits segment the electrode into functional units that can independently control liquid crystal deflection.
Solution Approach 2:
Instead of closing the slits to maintain structural integrity, the patent inverts the approach by leaving slits open and using the electrode portions surrounding them to provide the necessary structural support and electrical function, thereby achieving both structural integrity and light efficiency.
2Illumination intensity
If the electrode structure uses a fully open slit design, then the light efficiency is improved, but the structural stability deteriorates
Solution Approach 1:
Different regions of the electrode structure have different properties: the electrode portions provide structural stability and electrical conduction, while the slit regions provide light transmission pathways. This local differentiation allows the structure to achieve both stability and light efficiency simultaneously.
3Illumination intensity
If the electrode structure is designed with more electrode portions, then the light efficiency is improved, but the device complexity increases
Solution Approach 1:
The electrode portions serve multiple functions simultaneously: they provide structural support, conduct electrical signals, define slit boundaries, and control liquid crystal deflection. This multi-functionality reduces the need for separate components, thereby managing complexity while improving light efficiency.
4Ease of manufacture
If the electrode structure uses traditional design without slits, then the manufacturing process is simpler, but the light efficiency deteriorates
Solution Approach 1:
The slits are designed and positioned in advance during the electrode patterning process, integrating the light transmission function into the basic electrode structure fabrication. This preliminary incorporation of the slit design allows for simultaneous achievement of manufacturing simplicity and improved light efficiency without requiring additional complex processing steps.
