From the press release:
Iriver and LG Display have agreed to establish a joint venture company, ’L&I Electronic Technology (Dongguan) Ltd.’ in China to expand their e-book business.
Each Iriver and LG Display will finance 49% and 51% of the joint venture company, respectively, totaling up to 5 million dollars. The business will be founded on original equipment manufacturing (OEM) and original development manufacturing (ODM) systems to develop e-books and provide production services.
It looks to me like iriver has decided to adopt LG Display as their primary screen technology. This would make iriver the second company to use LG screens (Skiff is the first).
On a related note, LG Display had several different types of screens on display at SID Display Week.
