Description

Technical Field

[0001] The present invention relates to the technical field of electrical durability test equipment, in particular to an installation device for a display module electrical durability test and a use method thereof. Background Art

[0002] During the production process, display modules are subject to electrical durability tests to assess their performance. Only products that pass these tests meet factory standards. Generally, the electrical durability of a display module requires that the module be lit for 1,000 hours under normal operating conditions before its various performance indicators are tested.

[0003] The current electrical durability test for display modules involves soldering the display module to the corresponding PCB board, connecting them in parallel and applying power. The module is then illuminated for 1000 hours under normal conditions. After the test, the tin is removed from the PCB board and samples are taken for performance testing. However, this installation test method has drawbacks. For example, soldering is required for each use, which can lead to soldering quality issues such as cold soldering, missing soldering, and desoldering, affecting the test results after 1000 hours of durability and resulting in poor reliability. The soldering needs to be removed after each test, which is time-consuming, labor-intensive, and can easily damage the PCB board and display module. Selectively testing individual LEDs within the display module requires careful soldering, resulting in a long soldering time. Each test requires both a PCB and solder, leading to material waste. Therefore, there is an urgent need to design a simple-to-operate display module electrical durability test device that can save materials and improve work efficiency. Summary of the Invention
