Configuration control means that the display remains compatible in terms of appearance, suitability, functionality, etc., over a period of time. This essentially allows display manufacturers the flexibility to change sub-components to keep up with technology or market needs. It also allows users to transition to newer display products with minimal design changes. Product change is inevitable. The question is how quickly and to what extent product changes affect users based on time and resources. When implementing configuration control, it is very useful to manage changes to reduce impact.
Industrial-grade displays are designed to allow variation, and manufacturers strive to keep it to a minimum. When they need to change a product, they not only have a voice and recognized engineering/product change notification (ECN/PCN) program, but the information will be sent to customers in a timely manner allowing customers to adapt to the change without affecting their commercial business very much.
Typically, the manufacturer issues a PCN three months before the change is implemented. These changes will be archived and, where appropriate, customers can obtain samples of new products for testing prior to receipt of new products. In consumer displays, little configuration control is required, and the service market will not accept it. Most consumer displays are basically short-term sales, with no advance notice of changes.
