OLED technology enables the world's best displays, and as OLEDs can be made flexible, light, thin and highly efficient, these displays are especially useful in mobile devices such as wearables, smartphones and tablets.
AMOLED displays are already very popular in smartphones - in fact OLEDs are being adopted by high-end smartphones from all leading producers, including Samsung, Apple, LG, Xiaomi, Huawei and others.
The OLED tablet market
OLED displays traditionally found it more difficult to penetrate the tablet market. Larger displays are more expensive to produce and with the tablet market is smaller and of less interest to display markets, OLED producers did not focus on this market in the past - we're all waiting for an iPad air with an OLED display, or a Huawei tablet, or any android tablet for that matter with an OLED display.
Samsung, as the leading producer of mobile AMOLED displays, does use OLED displays in its high-end tablets. Samsung's newest tablet, the Galaxy Tab S4, for example, introduced in August 2018, sports a 10.5" 2560x1600 Super AMOLED display, a Qualcomm Snapdragon 835 Octa-core chipset, 4GB of RAM, 64/256 GB of storage and a microSD slot. The Tab S4 includes Samsung's S Pen and supports DeX. The Galaxy Tab S4 is now shipping for $649.99 for the Wi-Fi, 64GB model (note: affiliate link to Amazon) and $750 for the LTE, 256 GB model.
Towards the end of 2018 we have witnessed the emergence of a new class of display, foldable OLEDs. It is expected that in 2019 we will see the first wave of foldable devices, which could have interesting effects on the tablet market.
For example both Samsung and others demonstrated (in the case of Royole, also an early launch) foldable smartphones that open-up to a tablet-like device. These mobile hybrid phone/tablet devices could shake up the tablet market. While prices initially will be very high and production volume low, it is likely that only very high premium devices will appear and shipments will be limited. But in a few years it may be possible that the traditional tablet market will shrink as people will be able to combine their smartphones with their tablets in one sleek device.
