Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If coloring layers are positioned close to each other to reduce device thickness, then viewing angle characteristics deteriorate and color mixing increases, but if coloring layers are positioned far apart then device thickness increases
Solution Approach 1:
A structure body is introduced as an intermediary component between adjacent coloring layers. This structure body maintains a precise distance between the coloring layers, preventing them from being too close (which would cause color mixing and viewing angle issues) while also preventing excessive separation (which would increase device thickness). The structure body acts as a mediator that optimizes the spacing to achieve both thin profile and good viewing angle characteristics.
2Length of moving object
If coloring layers are positioned close to each other to reduce device thickness, then color mixing between adjacent pixels increases, but if coloring layers are positioned far apart then device thickness increases
Solution Approach 1:
The structure body serves as a physical barrier and spacing mechanism between adjacent coloring layers. By maintaining an optimized distance through the structure body, it prevents color mixing between adjacent pixels while keeping the overall device thickness minimal. The structure body ensures that coloring layers are close enough for a thin profile but far enough apart to prevent harmful color mixing.
3Reliability
If structure body is added between coloring layers to improve viewing angle characteristics, then device complexity increases, but if structure body is omitted then manufacturing becomes easier
Solution Approach 1:
The structure body is designed to perform multiple functions simultaneously: it acts as a spacing element to maintain optimal distance between coloring layers, serves as a viewing angle control component, and functions as a structural support element. By consolidating these multiple functions into a single component, the invention improves viewing angle characteristics without proportionally increasing device complexity.
4Reliability
If distance between electrode and coloring layer is reduced to improve viewing angle characteristics, then manufacturing precision requirements increase, but if distance is increased then viewing angle characteristics deteriorate
Solution Approach 1:
The structure body serves as a precise spacing intermediary between the electrode and coloring layer. It maintains a controlled distance that is optimized for viewing angle characteristics while providing a reference feature that simplifies manufacturing alignment. The structure body acts as a mediator that translates the requirement for precise distance control into a more manufacturable design with built-in positioning references.
