AIV-BEX, established in 2012 in Henan Province, China, aimed to produce small/medium AMOLED panels. The company was supposed to setup up a 4.5-Gen (730x920 mm) fab in Xinyang, Henan, to produce Oxide-TFT based OLED panels. AIV-BEX's first planned line was supposed to have a monthly capacity of 30,000 sheets and to begin production towards the end of 2015.
AIV-BEX's project never saw the light of day, and the company shut down.
