Light-on Module Tester for Defective Probe Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for testing light-on modules in display devices are inefficient, as they require production apparatuses and cannot accurately determine the position of defective probes, leading to reduced test efficiency and quality control issues.
Innovation Solution
A light-on module testing device with a base, support element, and test platform, equipped with a tester having test electrodes that match the probe structure, allowing for precise alignment and signal output analysis to identify abnormal probes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If production apparatuses are used for testing light-on modules, then testing can be performed, but production apparatuses are occupied and test efficiency is reduced
Solution Approach 1:
The invention separates the testing function from the production apparatus by creating a dedicated light-on module testing device. The testing process is segmented into independent components: a base, a support element with an arm for holding the light-on module, and a test platform with a tester. This segmentation allows testing to occur independently without occupying production apparatuses, thereby improving both reliability through specialized testing equipment and productivity by enabling parallel production and testing operations.
2Reliability
If conventional testing methods are used, then testing can be performed, but the position of defective probes cannot be accurately determined
Solution Approach 1:
The invention introduces a tester as an intermediary device between the light-on module and the testing process. The tester includes test electrodes that correspond to the probe structure of the light-on module, allowing precise alignment and signal output analysis. This intermediary enables accurate determination of defective probe positions by facilitating controlled electrical connection and signal measurement, thereby improving both defect detection capability and measurement precision.
3Productivity
If light-on modules are tested without a dedicated testing device, then production apparatuses can be used, but test efficiency is reduced and production line activation is delayed
Solution Approach 1:
The invention enables preliminary testing of light-on modules before they are integrated into the production line. The dedicated testing device allows complete testing procedures to be performed in advance, including electrical connection through corresponding test electrodes and probes, signal output analysis, and identification of defective probes. This preliminary action reduces testing time by eliminating the need for post-assembly testing and accelerates production line activation by ensuring quality control is already in place.
