Why is aging testing necessary for Flexible Transparent LED Film?

Aging testing is a critical step in product quality control, aimed at enhancing product reliability.

Aging Methods for Flexible Transparent LED Film
Aging methods include constant current aging and constant voltage aging. A constant current source maintains an unchanging current output. Constant current aging aligns best with the operational characteristics of LEDs, making it the most scientific approach for aging Flexible Transparent LED Film. It is also the latest method adopted by manufacturers. By using an adjustable frequency and adjustable current constant current source, potential issues such as color deviation and dead pixels can be identified in a short time, many of which cannot be detected through conventional aging methods.

Process of Flexible Transparent LED Film Aging and Illumination Testing

Step 1: Inspection

1. Check for any errors in the installation of transparent screen modules and cabinets.

2. Ensure the modules and cabinets are installed evenly with aligned seams.

3. Verify the screen and cabinets are in good condition without scratches or damage.

4. Inspect power and signal cables for issues such as short circuits, misconnections, or poor contact.

Step 2: Aging and Illumination

1. Use a connected control system to illuminate the screen.

2. Maintain continuous illumination for over 72 hours.

3. Aging methods include white light aging and video aging.

4. Aging approaches consist of constant current aging and constant voltage aging.

Step 3: Performance Testing

1. Test content: White screen, red/green/blue monochromatic displays, grayscale transitions, video effects, and text effects.

2. White screen testing duration: No less than 24 hours.

3. Monochromatic and grayscale transition testing: No less than 24 hours.

4. Video and text effects testing: No less than 24 hours.

By diligently following these steps, potential issues such as short circuits, dead pixels, and color deviation due to inadequate aging measures can be largely prevented. This ensures the stable and efficient operation of the transparent screen, maximizing its value.
