Display Panel Insulation Structure for Pixel Density and Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel technologies face challenges in improving pixel density and display performance due to limitations in insulation structure design, which lead to color crosstalk and light leakage, and require additional space for alignment accuracy during manufacturing.
Innovation Solution
The display panel design includes a first insulation structure with adjustable morphology, formed after the array layer and light-emitting element are prepared, using a light-blocking material to surround the light-emitting element, preventing crosstalk and light leakage by adjusting the shape of the insulation structure during the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional insulation structure is used, then the manufacturing process is simple, but color crosstalk and light leakage occur
Solution Approach 1:
The insulation structure is divided into multiple insulation subsections, each with specific geometric configurations. This segmentation allows the structure to simultaneously achieve light blocking functionality and color crosstalk prevention, resolving the contradiction between simple manufacturing and display performance.
Solution Approach 2:
Different regions of the insulation structure are designed with different properties - some regions have higher light-blocking capabilities while others provide structural support. This local differentiation enables the structure to prevent color crosstalk and light leakage in specific areas without requiring complete redesign of the entire insulation system.
2Manufacturing precision
If additional space is allocated for alignment accuracy, then manufacturing precision improves, but pixel density decreases
Solution Approach 1:
The insulation structure extends into the vertical dimension with optimized height and profile configurations. This three-dimensional design allows alignment tolerance to be compensated in the vertical direction rather than requiring additional horizontal space, thereby maintaining high pixel density while achieving manufacturing precision.
Solution Approach 2:
The insulation structure is designed with pre-configured geometric features that inherently guide alignment during the transfer process. The specific shapes and positions of insulation subsections create self-aligning effects, eliminating the need for additional alignment space while ensuring manufacturing precision.
3Reliability
If the insulation structure is made larger to prevent crosstalk, then color crosstalk is reduced, but the display area is reduced
Solution Approach 1:
The insulation subsections are designed with asymmetric geometric configurations optimized for their specific positions. This asymmetric design allows the structure to achieve effective light blocking and crosstalk prevention with minimal footprint, preventing the need to reduce display area while maintaining crosstalk prevention capability.
Solution Approach 2:
The insulation structure incorporates curved surfaces and rounded profiles instead of sharp angular shapes. This curvature optimizes light reflection and blocking paths, enabling effective crosstalk prevention with a more compact footprint that preserves maximum display area.

AI summary
The present disclosure provides a display panel and a manufacturing method thereof, and a display device. The display panel includes a substrate, an array layer disposed on one side of the substrate, a light-emitting element disposed on a side of the array layer away from the substrate, and a first insulation structure disposed on a side of the array layer away from the substrate and surrounding at least a portion of the light-emitting element. The first insulation structure includes a first insulation subsection, where an orthographic projection of the first insulation subsection onto the substrate at least partially overlaps with an orthographic projection of the array layer onto the substrate.
