Configuration control of industrial displays

Configuration control refers to the compatibility of a display in terms of appearance, applicability, functionality, etc. during a certain period of time. This basically allows display manufacturers to flexibly change sub components to keep up with technological or market needs. Users are also allowed to transition to updated display products with minimal design changes. Product changes are inevitable, and the question is how quickly and how much impact product changes have on users based on time and resources. It is very useful to reduce the impact by managing changes when implementing configuration control.
The design of industrial grade displays allows for changes, and manufacturers strive to keep changes to a minimum. When product changes are necessary, they not only have a sound and recognized Engineering/Product Change Notification (ECN/PCN) plan, but the information is also promptly sent to customers to allow them to adapt to the changes without significantly affecting their business operations.
Usually, the manufacturer will issue a PCN three months before the implementation of the change. These changes will then be recorded, and at the appropriate time, customers can obtain samples of the new product for testing before receiving it. There is almost no demand for configuration control in consumer displays, and it is not accepted by the service market. Most consumer displays are sold for a short period of time and changes are not notified in advance.
