Curved Display Panel Structure for Bezel-Less Support and Cooling
Find Innovative SolutionsGenerate Solutions
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 housing structure that includes a bracket and backcover for support, and a touch-sensing layer on the coverglass, along with an auxiliary display module for improved 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 panel is divided into multiple separate panels (first display panel and second display panel) that are arranged in a matrix configuration. This segmentation reduces the size of each individual panel, thereby improving support stability while maintaining the overall large screen area through the combined display surfaces.
2Area of stationary object
If the coverglass is extended to support touch operation on curved portions, then the touch area is increased, but the heat dissipation efficiency deteriorates in the curved portion
Solution Approach 1:
The display panel is divided into multiple separate panels (first display panel and second display panel) that are arranged in a matrix configuration. This segmentation reduces the size of each individual panel, thereby improving support stability while maintaining the overall large screen area through the combined display surfaces.
3Stability of the object's composition
If separate display panels are used for planar and curved portions, then the support stability is improved, but the device complexity increases
Solution Approach 1:
The housing structure is designed to universally support multiple types of display panels (planar and curved) through a common mounting framework. The housing includes a rear housing and front housing that collectively provide support for both planar and curved display portions, reducing overall device complexity despite using separate panels.
