Curved Window Integration on Polarization Layer for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices lack a seamless integration of curved designs and efficient manufacturing processes, leading to potential weaknesses in protection and aesthetics, particularly in the transition areas between display and non-display regions.
Innovation Solution
A display device design featuring a display panel with a flat area and a bending area, where a polarization layer and a window with a curved portion are integrated directly on the display panel, covering both display and non-display areas, and a method for manufacturing this device using a mold with a groove to form a resin coating layer that contacts the polarization layer, allowing for a smooth, curved window without additional processing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a window is integrated directly on the polarization layer covering the bending area, then aesthetic appeal and protection are enhanced through seamless curved surface, but manufacturing complexity increases due to integration requirements
Solution Approach 1:
The window is integrated directly on the polarization layer without additional processing steps, merging two components into a unified structure. This eliminates the need for separate assembly processes and achieves seamless curved surfaces that enhance aesthetic appeal while maintaining protection functionality.
Solution Approach 2:
The window is formed to cover the bending area before final assembly, preliminarily establishing the curved surface geometry. This preliminary action ensures that the curved portion is already in place during subsequent manufacturing steps, reducing the need for additional shaping operations.
2Reliability
If the window covers both display and non-display areas including bending area, then protection and aesthetic appeal are improved, but manufacturing precision requirements increase
Solution Approach 1:
The window is designed with different functional zones: a flat area covering the display area and a curved portion covering the non-display area and bending area. This local differentiation allows each region to be optimized for its specific function while maintaining overall integration, reducing precision requirements compared to a uniformly curved design.
Solution Approach 2:
The window includes a curved portion that smoothly transitions from the flat area, creating a seamless curved surface. This curvature is specifically positioned to cover the bending area of the display panel, providing both aesthetic appeal and protection while accommodating the panel's three-dimensional shape.
3Ease of manufacture
If the polarization layer is attached only on the flat area and separated from the bending area, then ease of manufacture is improved, but structural stability may be compromised
Solution Approach 1:
The polarization layer is segmented into two distinct regions: an attached portion on the flat area and a separated portion on the bending area. This segmentation allows the layer to be easily manufactured and attached only where needed, while the separated portion accommodates the bending area's movement and shape changes without compromising overall structural stability.

AI summary
A display device includes a display panel having a display area and a non-display area, a polarization layer on a first surface of the display panel and covering the display area and a portion of the non-display area adjacent to the display area, and a window directly on the polarization layer and covering the display area and the portion of the non-display area adjacent to the display area, the window including a curved portion on the portion of the non-display area.
