Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional separate integration of touch sensing and light emitting structures is used, then manufacturing and assembly are simpler, but device thickness increases and light intensity decreases
Solution Approach 1:
The patent merges the light emitting structure and touch sensing structure into a single integrated panel, eliminating the need for separate assembly. The light emitting layer and touch sensing electrode layer are formed together in one manufacturing process, reducing device thickness while maintaining light intensity and simplifying production.
Solution Approach 2:
The patent transitions from three-dimensional stacked integration to two-dimensional planar integration by forming both light emitting and touch sensing structures within the same panel plane. This dimensional approach reduces overall device thickness while preserving functional performance.
2Illumination intensity
If distance between light emitting and light conversion structures is increased, then manufacturing tolerance is easier to control, but light intensity and touch sensitivity decrease
Solution Approach 1:
The patent combines the formation of light emitting structures and light conversion structures into a single manufacturing step, ensuring they are precisely aligned from the outset. This eliminates subsequent alignment issues while maintaining minimal distance between structures for optimal light intensity and touch sensitivity.
3Ease of operation
If mesh structure electrode is used for touch sensing, then touch sensitivity improves, but light blocking increases
Solution Approach 1:
The patent applies local quality by making the electrode mesh structure transparent or using transparent conductive materials in regions where light transmission is critical. The mesh density and material properties are locally optimized to balance touch sensitivity requirements with light transmission needs.
