Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two display panels are bonded together to achieve double-sided display, then double-sided display function is realized, but device thickness and weight increase
Solution Approach 1:
The patent merges two light-emitting units into a single integrated structure where the first light-emitting unit emits light in a first direction and the second light-emitting unit emits light in a second direction opposite to the first direction. Both units share common electrode structures (first positive electrode plate and first negative electrode plate), eliminating the need for two separate display panels and reducing overall device thickness while maintaining double-sided display functionality.
Solution Approach 2:
The first positive electrode plate and first negative electrode plate serve multiple functions: they act as electrode structures for both the first light-emitting unit and the second light-emitting unit. This multi-functional design reduces the number of components needed and enables double-sided display without requiring two complete separate panel structures, thereby reducing thickness.
2Adaptability or versatility
If two display panels are bonded together to achieve double-sided display, then double-sided display function is realized, but device weight increases
Solution Approach 1:
The patent combines two light-emitting units into one integrated structure with shared electrode plates. By merging the panels and eliminating redundant components (such as duplicate electrode structures and substrates), the overall weight of the device is reduced while still achieving double-sided display capability.
3Adaptability or versatility
If light-emitting units emit light in opposite directions, then double-sided display is achieved, but electrode connection complexity increases
Solution Approach 1:
The first positive electrode plate and first negative electrode plate are designed to serve both light-emitting units simultaneously. This universal electrode structure simplifies the overall connection complexity compared to having separate electrode systems for each panel, as the same electrode plates are utilized for both the first and second light-emitting units.

AI summary
A double-sided display panel and a double-sided display device are provided. The double-sided display panel includes a light-emitting layer, a first connecting assembly, and a second connecting assembly. The light-emitting layer includes a first light-emitting unit and a second light-emitting unit. The first connecting assembly includes a first positive electrode plate and a first negative electrode plate, which are respectively electrically connected to the first light-emitting unit. The second connecting assembly includes a second positive electrode plate and a second negative electrode plate, which are respectively electrically connected to the connecting area of the second light-emitting unit. This can realize a double-sided display without increasing the thickness of the display panel.
