Solution Overview
Problem
Conventional display devices, such as LCD- and OLED-based systems, are costly and space-demanding, and transparent OLED displays are economically unviable due to high production costs and time consumption, while holographic structures on transparent surfaces are also costly and time-consuming to produce.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional LCD- or OLED-based display devices are used, then display functionality is achieved, but production costs and space requirements increase significantly
Solution Approach 1:
The patent uses a master hologram that can be replicated multiple times to create area elements. This copying approach allows a single master hologram to generate numerous identical area elements, significantly reducing production costs and time while maintaining consistent optical functionality across all elements.
Solution Approach 2:
The holographic structure is divided into multiple area elements that can be produced separately and then arranged to form a coherent area. This segmentation allows for easier manufacturing, transport, and assembly while achieving large-area holographic displays through combination of smaller units.
2Ease of manufacture
If transparent OLED displays are used, then transparency is achieved, but production costs become economically unviable
Solution Approach 1:
The master hologram replication process enables cost-effective production of transparent holographic structures. By copying the master hologram multiple times, the patent achieves economical production of transparent displays without requiring expensive transparent OLED technology.
3Illumination intensity
If holographic structures are produced on transparent surfaces, then desired optical properties are achieved, but production time and costs increase disproportionately with size
Solution Approach 1:
The patent divides the large-area holographic structure into multiple smaller area elements that can be produced in parallel from a master hologram. This segmentation enables simultaneous production of multiple elements, significantly reducing total production time compared to creating one large holographic structure at a time.
Solution Approach 2:
The master hologram is replicated to create multiple area elements simultaneously. This copying process is much faster than producing each area element individually, allowing large-area holographic structures to be assembled from pre-produced elements, thereby reducing overall production time.
4Area of stationary object
If area elements are arranged to form coherent areas, then size limitations are removed, but alignment precision requirements increase
Solution Approach 1:
The coherent area is formed by arranging multiple smaller area elements with defined geometric shapes. The segmentation into standardized elements with specific orientation relationships allows for systematic assembly while maintaining optical coherence across the entire area.
