Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular displays have large bezels, which negatively impact display effects.
Innovation Solution
A display device with a circular outer contour, featuring a display panel, a backlight module with a polygonal backplane, and an assembly frame that reduces the distance between the display area and the outer contour, thereby minimizing bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional circular display design is used, then the display can be formed, but the bezel size becomes large, affecting display effects
Solution Approach 1:
The patent transitions from a conventional circular arrangement to a polygonal backplane structure with multiple sides extending toward the display area. This dimensional reconfiguration allows the backlight module to occupy more space efficiently, reducing the bezel width while maintaining the circular outer contour of the display device.
Solution Approach 2:
The patent employs a polygonal backplane that approximates a circular shape through multiple straight sides, creating a curved-like appearance while using linear structural elements. This approach enables better space utilization compared to a simple circular backplane, allowing the side plates to extend closer to the display area and reduce bezel size.
2Shape
If the backlight module structure is optimized to reduce bezel size, then the display effect is improved, but the structural complexity increases
Solution Approach 1:
The backlight module is divided into multiple functional components: a polygonal backplane with multiple sides, multiple side plates corresponding to each side, and multiple light strips arranged along the sides. This segmentation allows each component to be optimized independently for minimizing bezel size while maintaining manufacturability and assembly feasibility.
Solution Approach 2:
The patent integrates the backplane, side plates, and light strips into a unified polygonal structure where these components work together as a cohesive system. The side plates are connected to the backplane and extend toward the display panel, creating an integrated assembly that reduces bezel size without requiring separate complex support structures.
