Display Panel Sidewall Adhesive Layout for Narrower Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display apparatuses face challenges in reducing the width of gaps between display panels, which affects the overall visual effect.
Innovation Solution
A display apparatus design that includes at least one display panel with a substrate, pixel array, conductive device, and protection adhesive. The protection adhesive is strategically positioned on the sidewall of the substrate, covering the conductive device, and has a specific geometry that allows for reduced gap width between panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display panels are arranged closely to reduce gap width, then the visual effect is improved, but the conductive device on the sidewall may be exposed or damaged
Solution Approach 1:
The protection adhesive extends from the front surface of the substrate to the sidewall, utilizing the vertical dimension to provide coverage. This multi-dimensional approach allows the adhesive to protect the conductive device on the sidewall while maintaining close panel spacing, effectively resolving the contradiction between reducing gap width and protecting exposed components.
2Reliability
If the protection adhesive covers the conductive device on the sidewall, then the reliability is improved, but the gap width between panels increases
Solution Approach 1:
The protection adhesive is applied selectively to specific regions: the front surface, sidewall, and back surface of the substrate. This localized application ensures that the conductive device on the sidewall is protected while minimizing the overall footprint of the adhesive, thereby reducing its impact on the gap width between adjacent panels.
3Reliability
If the protection adhesive extends to the sidewall, then the conductive device is covered, but the manufacturing complexity increases
Solution Approach 1:
The protection adhesive is divided into multiple regions with distinct functions: a first region on the front surface, a second region on the sidewall, and a third region on the back surface. This segmentation allows each region to be optimized for its specific purpose while simplifying the overall manufacturing process, as each segment can be applied and cured independently.

AI summary
A display apparatus includes at least one display panel that includes a substrate, a pixel array, a conductive device, and a protection adhesive. The pixel array is disposed on a front surface of the substrate. The conductive device is disposed at least on a sidewall of the substrate and electrically connected to the pixel array. The protection adhesive is disposed at least on the sidewall of the substrate and covers the conductive device. The protection adhesive has a first surface, a second surface, and a connecting surface which are disposed opposite to the sidewall of the substrate. A distance between the first surface and the sidewall of the substrate is greater than a distance between the second surface and the sidewall of the substrate. The connecting surface is connected to the first surface and the second surface.
