Display Frame Uplifted Parts Protect Driving Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face reliability issues due to damage to the driving circuit, which can occur when the frame does not adequately protect it, especially when the display panel bends and the glass substrate contacts the driving circuit.
Innovation Solution
A frame design with top and side uplifted parts that protrude from the main segments, forming an integral structure to create an inner space, which includes a top protrusion part at the same level as the upper substrate to support additional substrates and prevent damage to the driving circuit, and side protrusion parts to protect the driving line from external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the frame is designed with a simple flat structure, then the manufacturing process is simple and cost is low, but the driving circuit is vulnerable to damage when the display panel bends
Solution Approach 1:
The frame structure transitions from a two-dimensional flat planar design to a three-dimensional configuration by adding uplifted parts that protrude in the vertical direction. This dimensional change creates protective overhangs that shield the driving circuit from contact with the glass substrate during panel bending, while the uplifted parts themselves remain integrated into the frame's planar layout for straightforward manufacturing.
Solution Approach 2:
The frame is divided into distinct functional segments: the base frame structure and the uplifted protective parts. The top segment includes a top uplifted part that protrudes vertically, while the side segment includes a side uplifted part that protrudes horizontally. These segmented uplifted portions can be independently formed through standard fabrication processes and then integrated into the overall frame structure, maintaining manufacturing simplicity while providing targeted protection to vulnerable areas of the driving circuit.
2Reliability
If the frame includes uplifted parts to protect the driving circuit, then reliability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The uplifted protective parts are merged with the main frame structure through integral formation processes. The top uplifted part and side uplifted part are formed as continuous portions of the frame rather than separate components requiring assembly. This merging approach allows standard fabrication techniques to produce the complete frame with protective features in a single manufacturing flow, avoiding additional assembly steps and maintaining ease of manufacture while achieving reliable protection.
3Adaptability or versatility
If the top uplifted part protrudes to the same level as the upper substrate, then additional substrates can be supported, but the frame structure becomes more complex
Solution Approach 1:
The top uplifted part serves multiple functions simultaneously: it provides structural protection to the driving circuit by creating a protective overhang, and it serves as a support surface for additional substrates when needed. The vertical protrusion creates a stable platform that can accommodate various additional components or substrates while maintaining the same structural integrity and design simplicity, allowing the frame to adapt to different configuration requirements without increasing overall structural complexity.

AI summary
A display device includes a frame for receiving a display panel. The frame includes a bottom segment extending in a first direction, a top segment spaced from the bottom segment in a direction perpendicular to the first direction, the top segment extending in the first direction, and a side segment connecting a side of the bottom segment and a side of the top segment, the side segment extending in the first direction. The top segment includes a top uplifted part protruding in the direction perpendicular to the first direction.
