Display Panel Groove Reinforcement for Narrow Bezel Moisture Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in minimizing the bezel area and moisture permeation, which affect the reliability and aesthetic appeal.
Innovation Solution
The display device incorporates a display panel with a micro coating layer and a reinforcement plate featuring a groove, which minimizes the bezel size and reduces moisture permeation by minimizing contact with the molding member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reinforcement plate is added to protect the driving IC and minimize moisture permeation, then reliability is improved, but device complexity increases
Solution Approach 1:
The reinforcement plate is segmented with a groove that divides the plate into regions, allowing the micro coating layer to extend into the groove. This segmentation provides both mechanical reinforcement and moisture barrier functionality while maintaining a relatively simple overall structure.
Solution Approach 2:
The micro coating layer is nested within the groove of the reinforcement plate, creating a multi-layer protective structure. The coating layer fits into the groove space, providing moisture protection without adding significant external volume or complexity to the device.
2Reliability
If the micro coating layer is extended into the groove of the reinforcement plate, then moisture permeation is minimized, but manufacturing precision requirements increase
Solution Approach 1:
The groove is pre-formed in the reinforcement plate before the micro coating layer is applied. This preliminary structuring provides a defined pathway for the coating layer, guiding its extension and reducing the precision requirements for coating application compared to forming the structure after coating.
Solution Approach 2:
The groove acts as an intermediary structure that facilitates the integration of the micro coating layer with the reinforcement plate. It provides a physical guide and bonding interface that simplifies the manufacturing process and reduces precision requirements.

AI summary
A display device can include a display panel having an active area in which a plurality of pixels is disposed, a first non-active area adjacent to the active area, a bending area extending from one side of the first non-active area to be bent, and a second non-active area connected to the bending area. The display device further includes a micro coating layer disposed in the first non-active area, the bending area, and the second non-active area on the display panel, a driving IC disposed in the second non-active area, and a reinforcement plate disposed in the second non-active area. The reinforcement plate has one side disposed to enclose the driving IC and the other side disposed on the micro coating layer, and can further includes a groove disposed at the other side to correspond to the micro coating layer.
