Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an external mechanical force or shell in the backlight assembly is used to maintain the curved shape of the display panel, then the curved surface display can be achieved, but the assembly complexity increases and the device structure becomes more complicated
Solution Approach 1:
The deformation layer is configured to enable the display panel to generate deformation autonomously when reaching a specific temperature, without requiring external mechanical forces or shells. The deformation layer acts as a self-contained mechanism that curves the display panel internally, eliminating the need for complex external support structures and simplifying assembly
Solution Approach 2:
The invention extracts the curvature maintenance function from the backlight assembly shell and relocates it to the deformation layer integrated with the display panel. This separation allows the display panel to maintain its curved shape independently, removing the requirement for a specialized curved shell in the backlight assembly and reducing overall device complexity
2Shape
If an external mechanical force or shell in the backlight assembly is used to maintain the curved shape of the display panel, then the curved surface display can be achieved, but the device structure becomes more complicated
Solution Approach 1:
The deformation layer is integrated directly with the display panel structure, merging the curvature control function into the panel itself. This integration eliminates the need for separate curved support structures in the backlight assembly, simplifying both the manufacturing process and assembly procedures while maintaining the desired curved shape
3Device complexity
If a deformation layer with shape memory material is used to enable internal deformation of the display panel, then the assembly complexity is reduced, but additional materials and processing steps are required
Solution Approach 1:
The invention employs shape memory materials (such as shape memory alloys or shape memory polymers) as the deformation layer, which can be deposited or laminated onto the display panel. These composite material structures provide the necessary deformation capability while maintaining compatibility with existing manufacturing processes, balancing the added material requirements with simplified assembly
4Ease of operation
If the deformation layer is made of electrically-controlled shape memory material, then the deformation can be precisely controlled, but energy consumption increases
Solution Approach 1:
The electrically-controlled shape memory material is activated only when curvature change is required, using periodic or on-demand electrical stimulation rather than continuous energy input. This allows precise control of the deformation timing and extent, achieving the desired curved shape only when needed and reducing overall energy consumption compared to continuous mechanical support systems

AI summary
The present disclosure relates to the field of display technology and provides a display device and a method for manufacturing the same. The display device includes a first substrate and a second substrate arranged opposite to each other to form a display panel. A deformation layer is arranged on any surface of the display panel. Through the deformation layer on any surface of the display panel, when the deformation layer reaches a first deformation temperature, the deformation layer generates a deformation so as to apply an internal force to the display panel. Because the display panel is of a constant size, it is curved due to the internal force, so as to achieve curved-surface display. In other words, the display panel is curved under the effect of the internal force generated by itself, and it may be always maintained at its curved shape when the internal force is applied continuously. As a result, it is unnecessary to maintain the curved shape of the display panel with a shell of an existing backlight assembly, and thereby it is able to reduce the assembly difficulty.
