As 5-inch full-high-definition (FHD, 1920 × 1080 resolution) smartphone panels continue to gain traction and demand increases, manufacturers are beginning to implement new technologies to reduce power consumption at higher resolutions, according to NPD DisplaySearch (www.displaysearch.com). More than 100 million 5-inch 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-inch FHD 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," said Yoonsung...| Read more »
