Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are overlapped to increase display size, then the display area is increased, but display unevenness occurs due to light transmission interference
Solution Approach 1:
The display device is divided into multiple independent display panels (first display panel, second display panel, etc.), each with its own display region. These panels are arranged in an overlapping configuration where the display region of one panel overlaps with the non-display region of another panel, allowing the system to achieve a larger effective display area while maintaining uniformity within each panel's display region.
Solution Approach 2:
Different regions of the overlapping panels are assigned different functions: the display region of the first panel is optimized for light emission and display, while the non-display region of the second panel (which overlaps with it) is designed to be light-blocking or transparent as needed. This local differentiation allows the overlapping areas to function properly without causing display unevenness.
2Stability of the object's composition
If rigid substrates are used for display panels, then structural stability is maintained, but the display device cannot conform to curved surfaces
Solution Approach 1:
The display panels are constructed using flexible substrates instead of rigid ones. These flexible substrates allow the display panels to bend and conform to curved surfaces while maintaining their structural integrity and display functionality. The flexible nature enables the display device to adapt to various surface geometries.
3Reliability
If complex wiring is used to connect multiple display panels, then signal transmission is reliable, but device complexity increases
Solution Approach 1:
Wireless communication modules are integrated into the display panels to extract and eliminate the need for complex physical wiring connections between panels. The panels can communicate and coordinate their display content wirelessly, significantly reducing the physical wiring complexity while maintaining reliable signal transmission through wireless protocols.

AI summary
To provide a display device that is suitable for increasing in size, a display device in which display unevenness is suppressed, or a display device that can display an image along a curved surface. The display device includes a first display panel and a second display panel each including a pair of substrates. The first display panel and the second display panel each include a first region which can transmit visible light, a second region which can block visible light, and a third region which can perform display. The third region of the first display panel and the first region of the second display panel overlap each other. The third region of the first display panel and the second region of the second display panel do not overlap each other.
