Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional display technologies are used, then single-sided 2D display is achieved, but the device cannot provide double-sided 2D or naked-eye 3D display modes
Solution Approach 1:
The display substrate is segmented into multiple independent variable grating arrays (first, second, third, and fourth variable grating arrays) that can be independently controlled. Each grating array corresponds to specific light emitting elements and can switch between transparent and opaque states independently, enabling different display modes through selective activation of specific segments.
Solution Approach 2:
The same basic components (bidirectional light emitting elements and variable grating arrays) serve multiple functions depending on their configuration and control state. The display substrate can function as single-sided 2D display, double-sided 2D display, or naked-eye 3D display by controlling which grating arrays are transparent or opaque, making the system multi-functional without requiring separate hardware for each mode.
2Adaptability or versatility
If multiple display modes are provided, then applicability is improved, but the structural complexity increases
Solution Approach 1:
The variable grating arrays are designed to dynamically switch between transparent and opaque states based on control signals. This dynamic capability allows the display substrate to adapt its structure in real-time to provide different display modes, transforming a static complex structure into a dynamically controllable system that appears simpler in operation.
Solution Approach 2:
The invention introduces a new dimension of control through the transparent/opaque state switching of the variable grating arrays. This additional state dimension allows the same physical structure to achieve multiple display modes by varying the optical properties of specific regions, effectively adding a control dimension without increasing physical complexity.
