Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LCD or OLED display technology is used to display images with multiple colors by adjusting RGB mixture ratio, then color display capability is achieved, but light scattering occurs with large divergence angle causing crosstalk and reduced brightness
Solution Approach 1:
A light collimation module is introduced as an intermediary component between the display panel and the external environment. This module includes a liquid crystal layer that acts as a mediator to collimate the divergent light from RGB subpixels, reducing light scattering and crosstalk while maintaining display brightness
Solution Approach 2:
The light collimation module changes the directional parameters of emitted light by using liquid crystal molecules oriented in specific directions. By controlling the orientation and arrangement of liquid crystal molecules, the divergence angle of light is reduced, transforming scattered light into more directional beams
2Adaptability or versatility
If a liquid crystal steering structure is used in 3D display apparatus, then stereoscopic display capability is achieved, but light loss increases due to light scattering causing insufficient brightness
Solution Approach 1:
The light collimation module serves as an intermediary that reduces light loss before light reaches the liquid crystal steering structure. By collimating light earlier in the optical path, more light energy is preserved and directed efficiently through the 3D display system
Solution Approach 2:
Light collimation is performed preliminarily before light enters the liquid crystal steering structure. This preliminary action of gathering and directing light reduces subsequent light loss in the 3D display system, ensuring sufficient brightness is maintained throughout the optical path
