Despite slower demand from end market and panel price erosion, the large thin-film transistor (TFT) display market expanded in 2017 in all three aspects -- unit shipments...

“Demand for high-resolution panels has increased as media content for mobile PCs became available in higher resolutions,” said David Hsieh, senior director at IHS Markit. “Apple’ and Microsoft’s use of oxide TFT LCD panels for products – iPad, iPad Pro, and Surface, respectively – helped increase the oxide mobile PC panel market and encouraged other PC brands to follow suit.”
Low-temperature polysilicon (LTPS) and oxide TFT LCD solutions are major candidates for displaying high-resolution images, and they are expected to account for more than 19 percent of the entire mobile PC display market in 2017, according to the Large Area Display Market Tracker by IHS Markit.
While LTPS can deliver higher resolution images and consume less power than oxide TFT LCD or a-Si TFT LCD, it has its own limits: its production cost is high and the yield rate is low. In addition, it is less efficient to produce large panels. Albeit not as high resolution as LTPS, oxide TFT LCD panels still display high-resolution images better than the a-Si solution, and they are suitable to produce large panels at lower production cost than LTPS.
LG Display and Sharp have expanded their oxide mobile PC panel shipments aggressively by 180 percent and 370 percent, respectively. CEC Panda in China is estimated to increase its shipments from about 600,000 units in 2016 to 4.2 million in 2017. As some oxide panel suppliers are reducing their focus on the mobile PC display business, display makers in China and Taiwan, such as BOE and Innolux, are expected to produce more oxide panels in future, IHS Markit said.
