Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels face challenges in optimizing light transmission and functionality through the integration of functional components within the display area, particularly in achieving high light transmission efficiency and flexible design while maintaining image display quality.
Innovation Solution
The display panel incorporates a substrate with through-holes corresponding to specific areas, allowing for efficient light or sound output/reception by electronic elements, and a thin film encapsulation layer with inorganic and organic layers to optimize flexibility and light transmission, along with a conductive member with openings to reduce parasitic capacitance and enhance display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional components are integrated within the display area, then device functionality is enhanced, but light transmission efficiency deteriorates
Solution Approach 1:
The display area is divided into multiple pixel units, each containing functional components. This segmentation allows light transmission paths to be separated from functional component locations, enabling both high light transmission and integrated functionality. The pixel-level division permits strategic placement of openings and conductive members within individual pixels without compromising overall display performance.
Solution Approach 2:
Different regions within the display panel are assigned different properties: certain areas have openings for light transmission while others have conductive members for electrical functionality. This local differentiation allows simultaneous optimization of light transmission in specific zones and electrical performance in other zones, resolving the contradiction between functionality integration and light transmission efficiency.
2Illumination intensity
If through-holes are created in the substrate, then light transmission is improved, but structural integrity deteriorates
Solution Approach 1:
The substrate is designed as a thin film structure that can accommodate through-holes while maintaining sufficient mechanical strength. The thin film encapsulation layers are strategically positioned to provide structural support around the through-holes, allowing light transmission without compromising the overall structural integrity of the display panel.
3Manufacturing precision
If conductive members are added to reduce parasitic capacitance, then display quality is improved, but device complexity increases
Solution Approach 1:
The conductive members are merged with existing pixel electrode structures and wiring patterns. By integrating the parasitic capacitance reduction features into the existing conductive network rather than adding separate components, the display quality is improved while minimizing the increase in device complexity. The conductive members serve dual purposes: maintaining electrical connectivity and reducing parasitic effects.

AI summary
A display panel may include a first hole, a second hole, a display element, a switching element, a wire, and a conductive member. The second hole may be spaced from the first hole. The switching element may be electrically connected to the display element. The wire may bypass the first hole in a plan view of the display panel and may be electrically connected to the switching element. The conductive member may surround each of the first hole and the second hole in the plan view of the display panel, may have an opening between the first hole and the second hole in the plan view of the display panel, and may partially cover the wire. An edge portion of the conductive member may intersect the wire and may be positioned between the display element and the first hole in the plan view of the display panel.
