AMOLED displays are probably today’s most popular panels when talking about smartphone manufacturing (especially Android-based devices), but currently there aren’t that many companies developing the technology.

Samsung is, by far, the world’s most important AMOLED panel manufacturer, but the company’s leading position in the market niche might well be challenged soon enough. At least, that’s what we can make of one of Digitimes’ latest reports, which claims that AU Optronics and Chimei-Innolux are looking to get into the AMOLED business soon enough.

Both AUO and CMI are specialized in developing TFT-LCD panels at the time, but, if Digitimes’ sources prove to be correct, the two companies will begin mass producing AMOLED screens in just a matter of months. The second half of 2012 is the predicted ETA for AUO and CMI to get into the AMOLED business, with both companies doing extensive research in the field for several years already.

AUO, a Taiwanese-based company formed in 2001, will be looking to manufacture 4.3-inch AMOLED panels to be used mostly on Sony smartphones. Sony and AUO have reportedly partnered for research and development in the area for a while. They were planning to launch gadgets sporting new AMOLED screens in the second quarter of 2012, but have encountered production issues and will unveil their new devices in Q3 (sometime between July and September).

CMI, on the other hand, which is also based in Taiwan, but doesn’t yet have AUO’s tradition of working alongside important Android manufacturers, has even more ambitious plans. The company is looking to start mass production of two different AMOLED panels, one measuring 3.5″ and coming with a 326 ppi density, and the other having at 4.3″ and 257 ppi.

It’s unclear what CMI’s exact plans are with their future AMOLED displays, as Digitimes’ sources know nothing about a partnership with an Android device manufacturer, but we’ll probably know more when research and development is done and the panels are ready to enter production.

Digitimes is not exactly the most trustworthy source of rumors in the technology world, so you should take the report with a pinch of salt, but we’re hoping their sources are accurate this time around. After all, we love our AMOLED displays and there’s no better way for technology to thrive than increased competition, right?
