Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If large-size OLED display panels are produced directly, then the display size is increased, but the production yield decreases and production expenses increase due to poor heat dissipation and high power consumption
Solution Approach 1:
The display panel is divided into multiple light emitting units arranged in an array, with each unit containing multiple sub-pixels. This segmentation allows for better heat dissipation between units while achieving large overall display size. The segmentation also enables modular manufacturing and assembly, improving production yield.
Solution Approach 2:
The patent uses a 3D light field display technology with imaging holes and reflective members to create depth perception. This dimensional approach allows the display to achieve large visual impact without proportionally increasing the physical panel size, thereby maintaining better heat dissipation characteristics and production efficiency.
2Area of stationary object
If large-size OLED display panels are produced directly, then the display size is increased, but production expenses increase due to burn-in risks and manufacturing complexities
Solution Approach 1:
Heat dissipation structures are strategically placed between adjacent light emitting units where heat accumulation is most critical. The reflective members and imaging holes are positioned to optimize both light field effects and thermal management, addressing local quality issues without requiring complete redesign of the entire panel.
Solution Approach 2:
Heat dissipation structures are pre-integrated into the panel design before final assembly. The reflective members and imaging holes are configured in advance to establish optimal optical paths and thermal channels, preventing burn-in issues before they occur and simplifying the manufacturing process.
3Temperature
If heat dissipation structures are added between light emitting units, then heat dissipation is improved, but the device complexity increases
Solution Approach 1:
The structures between light emitting units serve multiple functions: they act as heat dissipation pathways, provide structural support, and facilitate light field control through reflective members and imaging holes. This multi-functionality reduces the need for separate dedicated heat dissipation components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent merges the heat dissipation function with the structural framework and optical control elements. The same structures that provide mechanical support and optical functionality also serve as thermal pathways, combining multiple functions into unified components rather than adding separate heat dissipation systems.
4Illumination intensity
If imaging holes are disposed on both sides of light emitting units, then light diffusion and display quality are enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The imaging holes and reflective members are configured to work together in a self-aligning manner. The optical paths are designed so that the imaging holes naturally guide light through the reflective members, providing self-correction capabilities that reduce the impact of manufacturing tolerances and lower the actual precision requirements.
Solution Approach 2:
The reflective members act as intermediaries between the light emitting units and the imaging holes. They facilitate light redirection and path optimization, compensating for minor positioning variations in the imaging holes and reducing the stringency of manufacturing precision requirements while maintaining light diffusion quality.
