Display Device Connector Alignment to Prevent Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face image quality defects due to undesirable bending of connectors, which can lead to cracks and image degradation, particularly when the horizontal distance between adhesive layers and the display drive unit is not optimally aligned.
Innovation Solution
The display device incorporates a specific configuration with adhesive layers and a touch sensor, where the horizontal distance between the second adhesive layer and the display drive unit is equal to or less than the distance between the display panel and the display drive unit, minimizing the risk of connector bending and crack formation by ensuring proper alignment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connector is mounted on the display panel without optimized alignment, then the device assembly is simplified, but the connector becomes prone to bending and cracking
Solution Approach 1:
The patent applies preliminary action by pre-positioning the connector at an optimized horizontal distance from the display drive unit during the assembly process. This predetermined positioning ensures that the connector is correctly aligned before final attachment, preventing bending and cracking while maintaining assembly simplicity. The connector's initial placement is critical to preventing subsequent mechanical failures.
Solution Approach 2:
The patent utilizes parameter changes by optimizing the horizontal distance parameter between the connector and display drive unit. By adjusting this specific dimensional parameter to an optimal value, the design achieves both ease of manufacture and high reliability. The horizontal distance is set to prevent excessive stress on the connector while maintaining practical assembly considerations.
2Manufacturing precision
If the horizontal distance between adhesive layer and display drive unit is increased, then alignment tolerance is improved, but connector bending risk increases
Solution Approach 1:
The patent applies parameter changes by optimizing the horizontal distance between the adhesive layer and display drive unit. This dimensional parameter is carefully selected to balance alignment tolerance with connector protection. The optimized distance provides sufficient tolerance for manufacturing variations while maintaining adequate support to prevent connector bending during assembly and operation.
3Stability of the object's composition
If the connector is positioned closer to the display drive unit, then connector stability is improved, but alignment precision requirements increase
Solution Approach 1:
The patent utilizes parameter changes by optimizing the horizontal distance parameter to achieve an optimal balance between connector stability and alignment precision requirements. The selected distance provides sufficient mechanical stability for the connector while maintaining reasonable alignment tolerance for manufacturing processes.
