Both competitive companies certainly don't want to disclose that kind of information, as rumors about the supposedly jointly-developed 'electronic viewfinder (EVF) using an OLED panel' hinted at, but external suppliers of raw materials like Hodogaya Chemical Co., Ltd. do (http://www.neogaf.com/forum/showpost.php?p=28688940&postcount=158), however that link is now useless to demonstrate anything because the articles I posted there have been deleted. MoCell's report is still accessible, though (http://www.neogaf.com/forum/showpost.php?p=28049846&postcount=673).
Also, its vendor procurement for a mass-produced low-cost device as this one is probably a cheaper and more efficient solution for them in the long term.
I think like this, but inverted, because if it was Sony we would have heard it from themselves quite some time ago. They usually state in promotional reports and press releases what kind of proprietary technologies apply or develop for specific products (specially for a key product like this one). I suppose that if a Sony Group subsidiary like Sony Mobile Display Corp. (former ST-LCD Corporation that also was not involved in the manufacturing of TFT-LCD modules for the PSP platform) was producing batches of the modules to be assembled on the PSVITA, they would probably have affirmed it by now.FoxSpirit said:There is none, but if it was Samsung we would have heard the news quite some time ago.
