Advanced Quality Control Processes for LED Display

Light Emitting Diodes (LEDs) are safely considered to be one of the most energy-efficient light sources and LED display products are, therefore, always in high demand. Most of the millennial consumers have become skeptical about their purchases and LED display products are no exception. LED display manufacturers face a lot of challenges when producing high-quality products in the rush to cater to millions of consumers. Here are some of the most advanced ways to ensure the LED display products matches the highest industry standards.

• Check the cabinet mechanism

The testing process involves monitoring the quality of the cabinets. The parameters of QC inspection for the cabinets include checking welding strength, painting quality, finishing, labeling, etc. The inspectors also need to ensure they find out a solution in case of any type of probable failure like rebuilding or modifying the cabinets.

• Screen assemblage testing

The main purpose of this test is to make sure the screen assembling process is perfectly conducted. It starts with assembling the screen on site. Here the inspection process includes detecting the gaps, simplifying the assemblage, testing the hanging and lock system, and checking the aesthetics of labeling. In case of any issues, the manufacturers are supposed to re-assemble the screen and rebuild the cabinets again.

• Control System and Image rendering tests

After the screen installation process according to the normal cabinet configuration, control system and image rendering tests are conducted. The testing is conducted on the basis of parameters including rcg/.con files and quality of the image/video. If required the rcg/.con files are subject to modification accordingly to the test results.

• Brightness, calibration and uniformity checking

Factors like brightness, calibration and uniformity forms the basis of a high-quality LED display screen. The QC inspectors check the brightness limit of the screen, evaluates the uniformity in RGB and white models, and check the quality of the mask. If the QC process reports any issues, then the manufacturers can recalibrate the screen, rearrange or change the masks accordingly.

• Checking on-site full white

An aging test is conducted at a full white range to test the performance of the screen. The testing process includes monitoring the image, heat dissipation, reliability of the soldering, and color consistency.

• Water-proof testing

An end-to-end waterproof testing is conducted for the outdoor cabinet to ensure no water infiltrates the screen, particularly for the front face.

• Check the spare parts and other specifications

From vetting the spare parts to testing the detailed specifications, a thorough product monitoring is performed. The inspection includes testing the wavelength, color temperature, diffusion angle, and other spare parts.

• Packing and shipping

This test is important to make sure the product is not susceptible to any damage during the transit activities. The monitoring procedure involves vibration check and resistance of the wooden boxes and flight cases. After the packing process is completed the shipping documents are reviewed with the packing list to avoid discrepancies during shipping. The review process is again subject to modifying the documents and changes in packing.
