In industrial display application scenarios, industrial-grade displays are exposed to high temperatures, dust or mechanical vibration environment for a long time, easily due to hardware aging or environmental erosion leading to performance degradation. Which can not be avoided display screen aging or wear and tear, such as in logistics, manufacturing, medical and other fields due to its high-frequency use of the characteristics, then we can choose to refurbish this type of equipment, refurbishment needs to be restored through systematic testing to restore functionality, and assess the cost-effectiveness, while reducing more than 50% of the procurement and maintenance costs, more economical.
So what are the technical challenges of monitor screen refurbishment?
1. Structural Inspection
The primary aspect of industrial monitor screen refurbishment is appearance and structure inspection. Due to salt spray, oil and other environmental factors are prone to interface corrosion or sealing failure, with the help of industrial endoscopes and other high-precision tools to detect internal damage. For example, by replacing the sealing ring and cleaning contacts, avoiding secondary failures caused by structural defects.
2. Circuit and backlight detection
For circuit and backlight detection, it is necessary to locate the short circuit or capacitor aging problem of multi-layer circuit board. In outdoor displays, the power module is often due to high temperature leading to capacitance failure, so monitor screen refurbishment is needed ，and after replacing the high-temperature-resistant capacitors during refurbishment, the cost of function restoration is only 20% of the cost of a new screen. This step can effectively extend the life of core components and reduce e-waste.
3.Display performance calibration
Display performance calibration is one of the core difficulties in refurbishment, especially in the field of medical treatment, design and other areas that require high color accuracy. For example, in the medical field, after the monitor screen refurbishment of the image display in medical institutions, the display error is reduced from 15% to 3% to meet the diagnostic standards through the grayscale calibration in a dust-free environment. This process requires the use of professional calibration equipment to ensure the consistency of brightness and color gamut.
4. Compatibility
Functional interface testing is required to verify the compatibility of industrial communication protocols (e.g. Modbus, CAN bus). After the monitor screen refurbishment of the control panel, if the communication protocol is not thoroughly tested, it may not be able to link with the existing equipment, so we need to solve the problem by checking the protocol configuration item by item. Such tests need to simulate actual working conditions to avoid compatibility risks during system integration.
