Display Panel Aging Test Trolley with Segmented Drawers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aging test apparatuses for display panels either limit the number of panels that can be tested simultaneously or require users to power off the panels to observe results, making it difficult to detect abnormalities during testing.
Innovation Solution
A trolley with symmetrically arranged carrying platforms and integrated power and signal generators allows multiple display panels to be tested simultaneously while maintaining a powered and observable state, enabling continuous monitoring of aging abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If drawer-type aging test apparatus is used to increase the number of display panels tested simultaneously, then the quantity of panels tested increases, but the panels must be powered off for observation making abnormality detection impossible
Solution Approach 1:
The apparatus is divided into multiple independent drawers, each capable of holding and testing display panels separately. This segmentation allows multiple panels to be tested simultaneously while maintaining individual control over each panel's power state, enabling abnormality detection without requiring all panels to be powered off together
Solution Approach 2:
A control system serves as an intermediary between the power supply and the display panels, enabling selective power control. The control system can maintain power to specific panels while others are powered off, allowing continuous monitoring of aging abnormalities without requiring complete system shutdown
2Reliability
If window-type aging test apparatus is used to allow direct observation of testing results, then abnormality detection is enabled, but only a small number of display panels can be placed for testing
Solution Approach 1:
The apparatus transitions from a single-chamber window-type design to a multi-drawer vertical configuration. This dimensional change allows multiple panels to be stacked vertically in separate drawers while maintaining observation capability through individual drawer transparency or remote monitoring interfaces
Solution Approach 2:
Each drawer is designed with universal functionality to hold and test display panels independently. The standardized drawer design allows multiple identical units to be stacked, increasing total testing capacity while each unit maintains its own observation and control capabilities

AI summary
Disclosed is a trolley, including: a trolley body, comprising a first support plate, and a second support plate perpendicular to the first support plate and fixedly defined on the upper surface of the first support plate; a plurality of carrying platforms, being perpendicular to the second support plate and symmetrically defined on two sides of the second support plate, the carrying platforms located on the same side of the second support plate being arranged in a row and equally spaced, to allow one end of the display panel to abut against the carrying platform, and the other end abut against the second support plate, for the display panel to be placed obliquely. Disclosed are also an aging test apparatus and system.
