Commercial adoption of small size AM-OLED panels steps up a gear

Increasing adoption of smartphone behind the growing interest in AM-OLED

26 Mar 2012 | editor

AM-OLED is being increasingly used on small-sized smartphone screens. Samsung is the major promoter of AM-OLED, and firms such as LG Diplay, AUO Optronics (AUO), and Chimei Innolux are all expected to launch their own AM-OLED panels for the smartphone market during 2012.

For example:-

  • Samsung is likely to launch a 4.6 inch Galaxy S3 with a pixel size of 319pp in the second half of 2012
  • Samsung plans to use AM-OLED displays in its next series of models, including the Omnia HD, Galaxy S, Galaxy S2, Galaxy S2 HD, and Galaxy Note LTE. Pixels will be increased from 198ppi to 285ppi, and the 3.7inch, 4 inch, 4.3 inch, and 4.65 inch sizes will be enlarged to 5.3 inches.

While Samsung is currently the number one supplier of AM-OLED panels, other display manufacturers are close behind most notably - LG Display, and LG Electronics. As a direct consequence of Samsung and LG activities in aggressively promoting AM-OLED for displays it has encouraged display manufacturers in Japan, Taiwan, and China to accelerated their own AM-OLED development and commercialisation plans. For example Taiwan's AUO and Japan's Idemitsu Kosan recently formed strategic alliances with upstream material suppliers, and will launch smartphone panels in the first half of 2012 with large-size AMOLED TV panels planned for the second half of 2012.

Chinese firms such as Visionox, Tianma Micro-electronics, and Irico have invested in the development of AM-OLED production lines, and it is reported that Huaxing Optoelectronics will establish its own Gen 4.5 pilot line. Overall, Chinese panel makers are expected to begin commercial production of AM-OLED panels in the 2013 and 2014 timeframe.

pite AM-OLED’s technical advantages and forecast sales of about of 90 million units LCD is still a cheaper display. The gap will close quickly as demands for AM-OLED displays is expected to increase rapidly over the next few years, and the price premium is forecast to reduce to 30% or less.
