Smartphone Makers Weigh Costs and Advantages of Four Kinds of TFT Process Technologies[10/30/2013 11:59 PM]
As 5” full-high-definition smartphone panels continue to gain traction and demand increases, manufacturers are beginning to implement new technologies to reduce power consumption at higher resolutions. More than 100 million 5” FHD smartphone panels will be shipped in 2013, 5% of all smartphone displays.
There are several manufacturing technologies that can produce the active matrix TFT backplane for 5” FHD (1920*1080) smartphone panels: traditional a-Si TFT, oxide TFT, and low temperature polysilicon (LTPS) TFT, all of which are used with LCD. LTPS TFT can also be used as a backplane for AMOLED (active matrix OLED) displays.
“While Apple iPhone suppliers are focused on the production of LTPS LCDs, others with experience in oxide TFT are trying to address the issue and gain a competitive advantage. Each of these technologies has its own advantages and disadvantages, and it will be critical for panel makers to choose the appropriate technology to reach their goals,” said Yoonsung Chung, director of large-area displays and FPD materials for NPD DisplaySearch.
The vast majority of smartphone LCD screens are now produced with a-Si TFT displays, due to its maturity and relatively low cost, despite the fact that it has lower performance than oxide or LTPS TFT. According to the latest NPD DisplaySearch Quarterly Smartphone and Tablet PC TFT LCD Cost Report, the manufacturing cost gap between a-Si and oxide screens is approximately 3 percent, and another 11 percent between oxide and LTPS TFT. As display performance continues to increase, however, the need for higher performance backplanes has grown, especially for high-resolution smartphone displays.
“Oxide TFT offers the potential to both lower cost and increase performance. The cost of oxide displays is comparable to a-Si displays, while the performance of oxide is closer to LTPS. However, instability, poor yield rate, and other technology hurdles could slow its adoption,” added Mr. Chung.
