I think it's an extremely smart strategy from Samsung to avoid putting all their eggs in one basket. Outside the USA, Apple's market share is not as important, as it is inside. And if you think about it, it's incredible hard to market a brand as being both: Premium AND Mass-Market.
For example, a Mass-Market brand, like Casio, may produce some nice Premium products [1], and those products may sell decently. But it's hard for them to target and sell products to people who want "the best", for the simple fact that subconsciously (and sadly) price and quality are mixed, and marketing exploits that fact. It doesn't have to be "the best" technically, but subjectively (perceived value, coolness, status brand and so on).
And of course, one of the main reasons that a product is considered Premium is its exclusivity. That's the problem that Armani faces right now, with its multiple brands targeted at different segments and markets, making their brand equity dilute[2]. Now imagine what would happen if Rolex made a cheaper watch, to compete with Casio.
Before you think I'm comparing in the same terms the competence between Apple/Samsung to Rolex/Casio (that hardly compete each other), I know it's not the best analogy. At least in the smartphone and tablet market, their products overlap. But what I'm saying is that their products are targeted to different segments. Apple is clearly a Premium brand. Samsung is a Mass-Market brand. Apple takes advantage of their brand value perception, and uses products like that screen to preserve and push that brand value forward. Samsung and the others instead, are focusing in the bigger market, people that will not spend half the household's monthly income (or even 2 or 3 full household's monthly income in some countries in Europe, Americas and Asia) in a computer. [3] So, they focus in building products with the best features possible while at the same time, having the lowest possible price. When they make a premium product, they do it to position their brand against other Mass-market Brands (DELL vs ASUS, Samsung vs HTC vs Motorola). Not to compete with a Premium Brand.
If those screens are still expensive to produce in large quantities, Samsung (or any other producing them) has not the need to create a product yet to use them, simply because they sell those screens anyway. And Apple is surely paying a nice premium to keep it that way. When they can start producing those screens at larger quantities, sure, there will be others using them.
But by keeping this strategy, Samsung is able to make money from both markets (premium and mass-market), while Apple is able to keep it's brand equity, in this case, by maintaining the exclusivity of the display. It's a very profitable win-win strategy.
And unless someone has VERY deep pockets to pay the same and more than Apple to cut the deal... (and Apple has lots of cash to avoid this from happening) I doubt that someone can offer those displays right now. Hopefully in a year, it will be easier and we can have more and more displays like this.
Until then...
"I doubt it would be that difficult for others to source an equivalent display"
Yes, it's that difficult. :)
