Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional LED display modules are used with separate LED display and 3D grating, then large-area high-brightness naked-eye 3D display is achieved, but the resolution is low and image quality is affected
Solution Approach 1:
The patent merges the LED display module and 3D grating into an integrated structure where the transparent grating panel is fixedly provided on the LED display module and located directly in front of the LED array. This integration improves resolution by ensuring precise alignment between LED dots and grating lines, eliminating the need for separate alignment processes while maintaining large-area high-brightness 3D display capability.
Solution Approach 2:
The display system is segmented into functional modules: LED display module, transparent grating panel, and driver circuitry. This modular segmentation allows independent optimization of each component while facilitating assembly and maintenance, resolving the contradiction between high resolution requiring precise integration and ease of manufacture requiring modularity.
2Productivity
If LED integrated panels are fixed with bolts for assembly, then stable connection is achieved, but assembly efficiency is low and disassembly is inconvenient
Solution Approach 1:
The patent replaces the traditional bolt-based mechanical fastening system with a snap-fit mechanism. The snap-fit structure includes a snap-fit groove on one panel and a corresponding snap-fit protrusion on the adjacent panel, enabling tool-free assembly and disassembly. This substitution dramatically improves assembly efficiency while maintaining connection stability through the elastic deformation and geometric interlocking of the snap-fit components.
3Illumination intensity
If LED display operates at high brightness, then good display effect is achieved, but heat generation is large and service life is reduced
Solution Approach 1:
The patent introduces heat dissipation structures as intermediary components between the LED light sources and the environment. These structures include heat dissipation fins and heat dissipation channels that facilitate thermal transfer from the high-brightness LED modules to the surrounding air, enabling sustained high brightness operation without excessive temperature buildup that would reduce service life.
4Measurement precision
If dynamic image display frequency is increased, then image quality is improved, but viewer dizziness is caused
Solution Approach 1:
The patent implements synchronized periodic control of LED pixel groups to display left-eye and right-eye images alternately at optimized frequencies. By carefully selecting the refresh frequency and synchronization timing, the system achieves high image quality through precise temporal separation of stereoscopic images while avoiding frequencies that trigger visual discomfort or dizziness in viewers.
