Foxconn Electronics reportedly plans to begin production of narrow-bezel, high-pixel-density small-size OLED panels for use in mobile devices in 2015, according to Taiwan-based supply chain makers.

Foxconn plans to have affiliated TFT-LCD panel maker Innolux undertake production at its factories in northern and southern Taiwan, the sources said.

In preparation for in-house panel development, Foxconn has invested US$1 billion to set up a display and touch panel R&D center in Japan, focusing on R&D for OLED and advanced touch solutions, the sources indicated.

Innolux has been developing OLED technology based on white-light OLED in combination with color filters, and will start small-volume production of 4-inch panels at the northern Taiwan factory and 5-inch and above panels at in southern Taiwan facility at the end of the first or beginning of the second quarter of 2014, the sources noted
