In the field of industrial monitors, especially in critical areas such as industrial automation, medical imaging and rail transportation, the reliability and stability of the monitor directly affects system safety and data accuracy. There are times when you may encounter problems with the screen, such as refurbished screen and original screen. Among them, the original screen uses customized components and strict quality control, while the refurbished screen reduces the cost by replacing non-core components, and there is a fundamental difference between the two in terms of durability and display performance.
So how to distinguish between the industrial monitor original screen and refurbished screen?
First, the appearance and process identification
Refurbished screen has been used, so it will often be sanded, painted to cover the traces of use, we need to carefully observe the defects. Industrial monitor original screen frame and screen seams tight, such as IP65 waterproof equipment seam tolerance ≤ 0.3mm, assembly screen due to aging and technical problems may appear more than 0.5mm gap, such as the original product frame using laser welding, refurbished parts more use of adhesive process, side light visible traces of glue overflow.
Second, display performance test
In the medical grade standard, the color consistency of the original screen reaches ΔE<2, while the refurbished screen generally ΔE>5. Through the DisplayHDR Test tool, the original screen can completely display the HDR400 standard brightness level, while the refurbished screen will be aging due to being used, so there are often faults in the dark details, and a delay of more than 5 seconds may occur.
Third, interface and firmware verification
Rail transit dispatching system requires the screen to support specific communication protocols. Industrial monitor original screen HDMI interface gold-plated layer thickness ≥ 15μm, in line with MIL-STD-202G standards, refurbished parts are mostly 5μm nickel-plated. Viewed through the engineering mode, the original firmware version number and the manufacturer’s record is consistent, such as Siemens SMART Line series firmware contains encrypted digital signatures, refurbished parts show “UNKNOWN” or verification failure.
Fourth, the certification mark verification
In some applications, such as high-end industrial monitors, military certification is required. The serial number of the original screen can be verified through the manufacturer’s database, while the CE mark of the refurbished screen is missing the certification body number.
