Display Panel Transition Structure for In-Display Component Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display apparatuses increase in size and resolution, integrating additional components within the display area poses challenges in terms of structural integrity and functional compatibility without compromising display quality.
Innovation Solution
A display panel design featuring a substrate with distinct areas for components and display elements, including a first area for components, a second area for display pixels, and a third area with a multi-layered film structure that allows for the integration of components by using contact portions and grooves to disconnect organic layers, ensuring electrical connectivity and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are integrated within the display area, then device functionality is enhanced, but structural integrity and display quality may be compromised
Solution Approach 1:
The display area is divided into multiple functional zones: a first area for display pixels, a second area for components, and a third area as a transition zone. This segmentation allows components to be integrated within the display area while maintaining distinct functional regions, thereby enhancing device functionality without compromising structural integrity or display quality.
Solution Approach 2:
Different areas of the display panel are assigned different structural characteristics. The first area maintains optimal display quality with complete multi-layer film structures, while the second area accommodates components with adjusted film structures, and the third area provides a gradual transition. This local differentiation enables component integration while preserving overall structural integrity.
2Adaptability or versatility
If components are integrated within the display area, then device versatility is improved, but display quality may deteriorate
Solution Approach 1:
The display panel is segmented into a first area dedicated to display pixels and a second area for components, with the third area serving as a transition zone. This segmentation ensures that the display area maintains optimal optical properties while the component area provides enhanced device versatility, preventing any deterioration of display quality.
Solution Approach 2:
The third area acts as an intermediary transition zone between the display area and the component area. This transition region gradually adjusts the film structure from complete (in the first area) to partially removed (in the second area), thereby maintaining display quality while enabling component integration and improving device versatility.
3Reliability
If multi-layered film structure is used for component integration, then electrical connectivity is achieved, but manufacturing complexity increases
Solution Approach 1:
The multi-layered film structure is selectively applied only in the first area for display pixels and the third area for transition, while being partially removed in the second area for components. This segmented application reduces overall manufacturing complexity compared to applying the complete structure across the entire display area, while still achieving the necessary electrical connectivity in the component region.

AI summary
A display panel includes: a substrate including a first area, a second area, and a third area located between the first area and the second area; a display layer including a display element located in the second area; a first metal layer located in the third area; an organic insulating layer located on the first metal layer and including at least one contact portion; and a second metal layer located on the organic insulating layer and contacting the first metal layer through the at least one contact portion, in which the second metal layer has a first hole, and the organic insulating layer has a second hole or a first recess corresponding to the first hole, and a residual layer located in the second hole or the first recess and including a part of at least one organic layer overlaps the first metal layer.
