Display Panel Filling Layer with Concave-Convex Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with functional modules, such as camera modules, face challenges in achieving optimal light transmittance due to protective layers that obstruct external light, leading to reduced performance.
Innovation Solution
A display panel design featuring a substrate with distinct areas, a concave-convex structure in the barrier part, and a filling layer that charges the first area efficiently before the second area, ensuring complete filling and increased light transmittance to the functional module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective layers are formed over the functional module to protect it from foreign material, then protection is improved, but light transmittance deteriorates
Solution Approach 1:
The filling layer is configured with a porous structure that allows light to pass through while providing physical protection to the functional module. The porous nature enables light transmission while the layer itself acts as a protective barrier against foreign materials.
Solution Approach 2:
The protective structure utilizes a composite configuration combining the filling layer with different material properties - the filling layer provides both protection and light transmission, while the barrier part provides structural support and additional protection. This composite approach resolves the contradiction by combining materials with complementary properties.
2Manufacturing precision
If the filling layer is designed to fill the first area completely, then filling completeness is improved, but manufacturing complexity increases
Solution Approach 1:
The display panel is divided into distinct areas (first area, second area, third area) with the filling layer specifically targeted to fill the first area. The barrier part is strategically positioned to define boundaries and control the filling process, segmenting the manufacturing complexity into manageable zones.
Solution Approach 2:
The barrier part acts as an intermediary structure that facilitates the filling process. By positioning the barrier part with specific geometric features (concave-convex structure), it guides the filling material into the first area and prevents it from entering the second area, thereby simplifying the manufacturing process while ensuring complete filling.

AI summary
A display panel includes a substrate including a first area, a second area surrounding the first area, and a third area surrounding the second area, and a barrier part disposed on the substrate in the second area and including a first partition including a concave-convex structure on a surface facing the first area in a plan view. The display panel further includes a filling layer disposed on the substrate in the first area and the second area and adjacent to the concave-convex structure and a light emitting diode layer disposed in the third area on the substrate and adjacent to the first partition.
