White balance consistency: Ensure that the entire LED splicing screen displays uniform color on the machine screen.
Brightness stability: Monitor the brightness attenuation of the LED splicing screen display machine.
Bad pixel control: Strictly control the display quality of the LED splicing screen display machine.
Power reliability: Verify the stability of the power supply system for the LED splicing screen display machine.
Heat dissipation performance: Evaluate the temperature control capability of LED splicing screen display machines during long-term operation.
Each LED splicing screen display machine parameter has a clear qualified range, and any deviation beyond the standard will result in the product being retested or repaired.
Detailed LED splicing screen display machine testing process.
The aging test of Ruiguan Electronics is a multi-stage process of a system:
Thermal aging process
The LED splicing screen display machine screen works continuously in a constant temperature environment of 40 ℃.
This moderate heating can accelerate the aging of components, help us screen out those components of the LED splicing screen display machine with insufficient heat resistance, and ensure the reliability of the product in various environments.
Dynamic image testing
We use professional testing signals to switch the LED splicing screen display machine screen between different image modes.
From solid color to gradient, from static to dynamic, comprehensively test the response speed and color performance of the screen.
Power stress test
We test the stability of the power supply module under different loads by displaying the machine's power output through a precisely controlled LED splicing screen.
This test can detect hidden power issues at standard voltage.
Power on/off cycle test
Perform power on and off operations at precise time intervals, simulate the frequent start stop of the LED splicing screen display machine during actual use.
This process tests the durability of the power and drive circuits of the LED splicing screen display machine.
