Oxide semiconductors are potentially a revolutionary technology that would negate the need for Si crystallization and enable large size, high quality, low-cost AMOLED displays. Whether or not this will actually happen is still to be determined. Oxide semiconductor technology for display applications is not a mature technology and repeatability is said to be a significant issue. Currently all AMOLEDs in mass production are fabricated with some version of ELA or solid phase crystallization. Sony is investing in a dTLA (Diode Thermal Laser Annealing) pilot line to prove the manufacturability of its µc-Si technology. Others pursuing direct deposit p-Si, RTA (Rapid Thermal Annealing) and other techniques to overcome the continued uniformity, cost and scaling problems related to ELA. But, at least, the strong interest by the SID paper selection committee and the impressive results shown by Samsung SDI and others, suggest that oxide semiconductors are a technology to keep a close eye on when evaluating future AMOLED opportunity.
