Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensor area is integrated within the display area, then device functionality and versatility are improved, but display resolution and quality may deteriorate
Solution Approach 1:
The display area is divided into distinct regions: a first pixel area for high-resolution display and a second pixel area for sensor integration. This segmentation allows each region to be optimized independently, with the first pixel area maintaining high manufacturing precision while the second pixel area accommodates sensor components, thereby resolving the contradiction between functionality and display quality.
Solution Approach 2:
Different pixel structures are implemented in different areas: the first pixel area uses a standard high-resolution pixel structure, while the second pixel area uses a modified structure with transparent portions and adjusted electrode arrangements to accommodate sensors. This local differentiation enables high display quality in the first area while providing sensor integration capability in the second area.
2Illumination intensity
If electrode layers are arranged to bypass transmission portions, then light transmittance is improved, but device complexity increases
Solution Approach 1:
The electrode layers are designed with flexible routing that dynamically adapts to the transmission portion layout. Instead of rigid straight-line connections, the electrodes follow optimized paths that bypass transparent regions, allowing light to pass through while maintaining electrical connectivity. This dynamic routing approach improves light transmittance without requiring complete redesign of the electrode system.
Solution Approach 2:
The electrode layers act as intermediaries that mediate between the need for electrical connectivity and the need for light transmission. By strategically positioning electrodes to overlap with spacing regions rather than transmission portions, the design allows both functions to coexist, with the electrode arrangement serving as a mediating structure that satisfies both electrical and optical requirements.
3Weight of stationary object
If sensor area is integrated in display area, then device thickness and weight are reduced, but light transmittance and sensor performance may deteriorate
Solution Approach 1:
The second pixel area incorporates transparent portions that function similarly to porous structures, allowing light to pass through while providing structural support for sensor components. These transparent regions reduce the optical burden on the sensor area, enabling better light transmittance despite the integrated sensor structure, thereby maintaining both weight reduction and optical performance.
