Narrow Bending Region Layout for Compact Bezel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the size of the bezel and case surrounding the display area due to the width of the bending region, which affects the overall device dimensions and aesthetics.
Innovation Solution
A display device design featuring a substrate with 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 Contradiction Analysis
1Area of stationary object
If the bending region has a width equal to or greater than the second region, then the structural stability and ease of manufacturing are improved, but the overall device size and bezel dimensions increase
Solution Approach 1:
The substrate is divided into three distinct regions: a first region for image display, a second region for pad terminals, and a bending region connecting them. This segmentation allows each region to be optimized independently, with the bending region specifically designed to be narrower than traditional designs while still fulfilling its structural function of connecting the display region to the terminal region.
Solution Approach 2:
The bending region is designed with non-uniform width characteristics, being narrower at certain portions compared to the second region. This local variation in dimensions allows the device to achieve a compact overall form factor while maintaining adequate space for electrical connections and structural integrity in the terminal region.
2Shape
If the bending region width is reduced to minimize bezel size, then the aesthetic appeal and compactness are improved, but the reliability of electrical connections may deteriorate
Solution Approach 1:
The pad terminals in the second region are arranged in a multi-dimensional configuration, allowing electrical connections to be established through both the bending region and direct connections in the terminal region. This spatial arrangement ensures reliable electrical connectivity even when the bending region has reduced width.
Solution Approach 2:
The second region serves multiple functions: it houses the pad terminals for electrical connections, provides structural support, and facilitates the transition from the narrow bending region to the display region. This multi-functionality ensures that reducing the bending region width does not compromise connection reliability.

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.
