Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional transparent display technologies (LCD, OLED) are used, then display functionality is achieved, but transmittance is low and production costs are high
Solution Approach 1:
The patent combines a transparent display panel with a projecting apparatus to form an integrated display system. The projector displays images on the transparent panel, merging two separate display functions into one system, thereby achieving high transmittance display without the high costs of traditional transparent OLED or LCD technologies
Solution Approach 2:
Instead of using expensive transparent display panels directly, the system uses a projector to create an optical copy of the image on the transparent panel. This copying approach allows standard opaque projectors to be used with transparent panels, significantly reducing production costs while maintaining high transmittance
2Reliability
If image information is displayed on both the transparent panel and projected simultaneously, then display effect is enhanced, but synchronization difficulty increases
Solution Approach 1:
The control device receives image information and coordinates the display timing between the transparent panel and projector. By implementing feedback control where the controller monitors and adjusts the display timing of both components, the system achieves synchronized display without excessive complexity
Solution Approach 2:
The control device serves multiple functions: it manages the transparent display panel, coordinates the projector timing, and handles image information processing. This multi-functional controller simplifies the overall system by consolidating synchronization control into a single universal device rather than requiring separate control mechanisms for each component
3Illumination intensity
If brightness is increased for better visibility, then display visibility is improved, but power consumption increases
Solution Approach 1:
The system uses a projector that displays images in periodic frames rather than continuous illumination. This periodic action allows the display to achieve necessary brightness for visibility while consuming significantly less power compared to continuously illuminated transparent LCD or OLED panels
Solution Approach 2:
The patent replaces the electrical illumination system of traditional transparent displays with an optical projection system. Instead of using high-power backlight units or self-luminous OLEDs, the system uses light from a projector that is modulated to create the display image, dramatically reducing power consumption while maintaining visibility
