Solution Overview
Problem
The challenge of reducing the manufacturing difficulty and assembly time for curved screens in electronic devices has become an important issue due to their complex structure and assembly requirements.
Innovation Solution
A curved backlight module with a curved back plate and a fixing member that includes protruding portions and fixing portions arranged at unequal intervals, along with a display module affixed via a glue and locking mechanisms, to match the curvature of the back plate for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a curved screen structure is used, then external light interference is reduced and contrast is improved, but manufacturing difficulty and assembly complexity increase
Solution Approach 1:
A curved fixing member is introduced as an intermediary component between the flat display module and the curved back plate. This fixing member includes protruding portions that contact the display module and fixing portions that attach to the back plate, serving as a mediator to transfer the curved shape from the back plate to the display module during assembly
Solution Approach 2:
The fixing member is designed with a curved structure that matches the curvature of the back plate. The first side of the fixing member has a greater curvature than the second side, allowing it to conform to the curved surface and maintain proper contact and attachment throughout the assembly
2Ease of manufacture
If traditional equal-interval fixing portions are used, then assembly is simpler, but assembly reliability and structural stability are insufficient
Solution Approach 1:
The fixing portions are arranged at unequal intervals along the curved surface, with higher density on the first side (with greater curvature) and lower density on the second side. This non-uniform distribution provides enhanced structural stability and assembly reliability at critical locations while maintaining manufacturing feasibility
3Ease of manufacture
If the fixing member has uniform curvature, then manufacturing is easier, but it cannot properly match the curved back plate surface
Solution Approach 1:
The fixing member is designed with non-uniform curvature where the first side has a greater curvature than the second side. This localized variation in curvature allows the fixing member to precisely match the curved surface of the back plate, ensuring proper contact and attachment while remaining manufacturable

AI summary
An electronic device is provided, including a curved backlight module, a display module, and a fixing member. The curved backlight module includes a curved back plate. The display module is disposed on the curved backlight module and comprises an inner surface facing the curved backlight module. The fixing member comprises at least one protruding portion that is in contact with the inner surface. The fixing member is configured to affix the display module to the curved back plate. The fixing member comprises a plurality of fixing portion, and at least some of the plurality of the fixing portions are arranged at unequal intervals. A density of the fixing portions on a first side of the fixing member is greater than a density of the fixing portions on a second side of the fixing member, wherein a curvature of the first side is greater than a curvature of the second side.
