Narrow Bending Region Layout for Reduced Display Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the size of the bezel and the enclosing case due to the width of the bending region, which affects the overall compactness and design aesthetics.
Innovation Solution
A display device with a substrate featuring a first region for image display, a second region for pad terminals, and a bending region connecting the two, where the bending region is configured to bend along a specific axis with a narrower width than the second region, allowing for a more compact design by reducing the size of the bezel and enclosing case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bending region has a larger width, then the structural stability and ease of manufacture are improved, but the overall device size and bezel width increase
Solution Approach 1:
The patent changes the geometric parameters of the bending region by making its width narrower than both the display region and pad region. This parameter optimization allows the bending region to achieve sufficient structural stability while minimizing the overall device width and bezel dimensions, resolving the contradiction between ease of manufacture and compact size.
Solution Approach 2:
The patent transitions from a conventional uniform-width bending region to a tapered bending region that varies in width across different dimensions. By making the bending region narrower in the width dimension while maintaining adequate length for bending operations, the design achieves compactness without sacrificing manufacturability.
2Volume of moving object
If the bending region width is reduced, then the device compactness and aesthetic appeal are improved, but the structural stability and manufacturing ease deteriorate
Solution Approach 1:
The patent optimizes the width parameter of the bending region to be narrower than both adjacent regions. This parameter change achieves the desired device compactness and aesthetic appeal while the maintained length and proper material selection ensure sufficient structural stability for manufacturing.
Solution Approach 2:
The patent employs composite material structures in the bending region to achieve both compact dimensions and structural stability. The composite construction allows the bending region to be narrower while maintaining the necessary mechanical strength and flexibility for successful manufacturing and assembly.
3Length of stationary object
If the bending region is made narrower, then the bezel size is reduced, but the structural integrity and reliability may be compromised
Solution Approach 1:
The patent changes the width parameter of the bending region to be narrower than the display and pad regions, which reduces the bezel size. The proper selection of materials and structural design compensates for this dimension reduction, maintaining sufficient structural integrity and reliability.
Solution Approach 2:
The patent uses composite material construction in the bending region to maintain structural integrity despite the reduced width. The composite structure provides the necessary strength and flexibility to ensure reliability while achieving a narrower bezel design.

AI summary
A display device includes a substrate having a first region in which an image is displayed, a second region in which an image is not displayed, and a bending region connecting the first region and the second region. The bending region is configured to bend along a bending axis which extends in a first direction. A plurality of pad terminals is disposed within the second region. A first width of the bending region, measured along the first direction, is narrower than a second width of the second region, measured along the first direction.
