As
x RELIC x has alluded to, above, James has explained, a number of times, in the past, on this forum, why he can't just use the latest & greatest screen, of any size and type he likes:

Admittedly, the T3 is likely to have a touchscreen, so it is a slightly different situation from the surplus Blackberry screens Fiio used on the X3 and x5, but
still, Fiio has to obtain what, in smartphone-manufacturing terms, is a relatively small quantity of screens, for the T3, so their buying power is relatively limited, and they can't afford to be too picky with their screen suppliers. In the last 2-3 years, there has been a relentless drive by smartphone manufacturers, to increase the size of their touchscreens - it's a silly gimmick that makes smartphones harder to use with one hand (Steve Jobs resisted making the iPhone screen larger, for precisely this reason), but it's the way the smartphone industry has been going. This means that even mass-produced smartphone touchscreen suppliers will have less and less stock of smaller touchscreens, and the T3 doesn't really want to have a massive touchscreen. The point being that James and his team will not have a great deal of choice, if they are seeking to obtain a relatively-compact touchscreen for the T3, and they also have to get them at an economical price, which may be difficult.
