Foldable Non-Display Region for OLED Encapsulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in organic light-emitting display apparatuses is to reduce the visible size of the non-display region while maintaining high display quality and manufacturing efficiency, as the demand for larger and higher-quality displays increases, making it difficult to minimize the number of circuits and wirings without compromising performance.
Innovation Solution
The solution involves a foldable non-display region on an organic light-emitting display apparatus with a flexible substrate, where the non-display region is folded to cover the side surfaces of the encapsulation member and supporting substrate, using a sealant to adhere these components together, thereby reducing the visible border and ensuring a sufficient manufacturing margin without reducing circuit density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the non-display region is made smaller to improve display quality and aesthetics, then the visible border is reduced and design margin is improved, but it becomes difficult to accommodate sufficient circuits and wirings without compromising manufacturing efficiency
Solution Approach 1:
The non-display region is folded along a fold line to create a three-dimensional structure where the folded portion covers the side surfaces of the encapsulation member and supporting substrate. This dimensional transformation allows the non-display region to be minimized in the two-dimensional visible plane while maintaining sufficient area for circuits and wirings in the folded configuration, thereby resolving the contradiction between reducing visible border area and maintaining manufacturing efficiency
2Area of stationary object
If the non-display region is reduced in size to improve aesthetics and display quality, then the recognizable border is decreased, but the design margin with respect to dead space is compromised
Solution Approach 1:
By folding the non-display region to cover the side surfaces, the design margin is preserved in the folded structure even though the visible area is minimized. The foldable configuration allows sufficient space for circuits and wirings to be accommodated without compromising manufacturing precision, while achieving the aesthetic goal of reduced visible border
3Area of stationary object
If the flexible substrate is used to enable foldable non-display region, then the visible border is reduced and aesthetics are improved, but mechanical stability and reliability may be compromised
Solution Approach 1:
The foldable structure created by folding the non-display region along the fold line provides both aesthetic benefits (reduced visible border) and mechanical stability. The folded configuration allows the flexible substrate to maintain structural integrity while achieving the desired visual effect, as the folding creates a stable three-dimensional form that supports the encapsulation member and supporting substrate

AI summary
An organic light-emitting display apparatus includes a flexible substrate having a display region and a non-display region located at an outer region of the display region, the non-display region being folded with respect to the display region; at least one organic light-emitting diode (OLED) on the display region of the flexible substrate; and an encapsulation member encapsulating the display region.
