Aging Pallet Press Bar Protrusions for Display Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aging pallets used in the aging process of display panels can damage the panels due to particles on the press bars, causing surface damage and pressure issues during the high-temperature aging process.
Innovation Solution
The aging pallet design includes a base plate with stacked trays, each featuring a seating portion and a press bar with protrusions that extend towards the seating portion, and magnetic elements between protrusions to collect particles, minimizing pressure and preventing damage by uniformly pressing the display panel and collecting foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a press bar is used to apply pressure during the aging process, then the display panel can be pressed uniformly, but particles on the press bar surface can damage the display panel
Solution Approach 1:
The press bar surface is segmented into multiple protrusions spaced apart from each other, creating discrete contact points instead of a continuous surface. This segmentation reduces the total contact area and minimizes the risk of particle damage while maintaining uniform pressing through the distributed protrusion array.
Solution Approach 2:
The press bar features localized protrusions with specific geometric characteristics (spaced apart, specific height and width ratios) rather than a uniform surface. This local quality modification allows the press bar to apply pressure effectively at discrete points while reducing the overall surface area that could harbor particles.
2Object-affected harmful factors
If the press bar surface area is reduced to minimize particle contact, then particle damage is reduced, but the pressing uniformity may be compromised
Solution Approach 1:
The press bar is divided into multiple protrusions distributed across the surface, creating many small contact points that collectively provide uniform pressure distribution. The segmentation allows reduced total contact area while maintaining pressing uniformity through the distributed array of protrusions.
Solution Approach 2:
The pressing function is transitioned from a two-dimensional continuous surface contact to a three-dimensional array of discrete protrusions. This dimensional change allows the press bar to maintain effective pressing while reducing surface area, as the protrusions extend in the vertical dimension to provide sufficient contact pressure.
3Object-affected harmful factors
If multiple protrusions are used on the press bar, then particle contact is minimized, but the device complexity increases
Solution Approach 1:
The press bar is segmented into multiple protrusions that can be manufactured as an integrated structure. While the surface geometry is complex, the segmentation is achieved through a single manufacturing process, avoiding the need for multiple separate components and assembly steps.
Solution Approach 2:
The protrusion array structure serves multiple functions simultaneously: it provides uniform pressing through distributed contact points, minimizes particle damage through reduced surface area, and can be manufactured as a single integrated component. This multi-functionality offsets the increased geometric complexity.

AI summary
An aging pallet used in an aging process of a display panel is provided. The aging pallet can include a plurality of trays stacked on a driving unit. Each of the plurality of trays can include a seating portion on which the display panel is mounted, and at least one press bar disposed on the seating portion. The press bar can include protrusions protruding toward the seating portion or holes disposed at a surface of the press body toward the seating portion. Thus, the aging pallet can prevent the damage to the display panel due to particles in the aging process.
