Solution Overview
Problem
Existing display devices with large screens face challenges in achieving a bezel-less structure while maintaining support stability and efficient heat dissipation, particularly in curved portions.
Innovation Solution
A curved display device design incorporating separate display panels for planar and curved portions, with a coverglass featuring a touch-sensing layer and a housing that includes brackets and modules for support, along with an auxiliary display module for the curved portion, enhancing stability and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large display panel is used to achieve a bezel-less structure, then the screen area is maximized, but the support stability deteriorates due to the large size and weight of the coverglass
Solution Approach 1:
The display device is divided into multiple separate display panels (first display panel and second display panel) that are arranged adjacent to each other. This segmentation allows each panel to be supported independently, improving overall support stability while maintaining a large combined screen area and achieving a bezel-less structure.
2Area of stationary object
If a single large display panel is used to eliminate bezels, then the visual continuity is improved, but the heat dissipation efficiency deteriorates due to the large area and concentrated heat generation
Solution Approach 1:
The display system is segmented into multiple separate display panels with independent support structures and spacing. This segmentation creates distributed heat generation zones rather than one concentrated hot zone, improving heat dissipation efficiency while maintaining a large overall screen area.
3Adaptability or versatility
If separate display panels are used for planar and curved portions, then the adaptability to different surface geometries is improved, but the device complexity increases due to multiple panels and support structures
Solution Approach 1:
The display system is segmented into separate panels that can be independently configured for different surface geometries (planar and curved portions). This segmentation provides adaptability to various surface shapes while the modular nature of separate panels actually simplifies the overall design compared to attempting to create a single complex panel that could handle multiple geometries.
Solution Approach 2:
Different display panels are used with different local properties - some panels are configured for planar surfaces while others are configured for curved surfaces. This local quality approach allows each panel to be optimized for its specific location and surface geometry, improving overall adaptability while keeping individual panel designs relatively simple.
4Area of stationary object
If the coverglass is made larger to eliminate bezels, then the aesthetic appearance is improved, but the manufacturing precision requirements worsen due to the increased size and curvature
Solution Approach 1:
The coverglass and display system are segmented into multiple smaller components (separate display panels with their own support structures). This segmentation reduces the manufacturing precision requirements for each individual component compared to creating one extremely large, complex curved coverglass, while still achieving a large overall aesthetic display area.
