To me it depends. You might not actually want to produce your own screens, or what ever else you currently buy instead of making it yourself. Because that would require dedicated resources, diverted from your core competencies. But you might have someone, or a small team, look into it. Work out what you might need to do, what it is going to cost. Then you take that research and knock on your suppliers door and ask for a better price. I'm not saying that is what is happening here, but it could be a viable negotiation strategy.
