According to DisplaySearch, tablets makers are expected to increase OLED display adoptions due to their thin profile and low power consumption, and AMOLED tablet shipments will reach 42 million by 2019, up from about 4 million OLED tablets sold in 2014. In 2015 OLED technology is expected to hold a 5% in the AMOLED display market.
Currently the only AMOLED tablets on the market are Samsung's Galaxy Tab S series, launched in June 2014 (8.4" and 10.5"). Both Super AMOLED displays offer the same resolution - WQXGA (2560x1600), which means 359 PPI for the 8.4" tablet and 287 for the 10.5" one. DisplayMate says these OLED displays are the best tablet displays ever tested.
Dell also announced an upcoming 8.4" tablet (the Dell Venue 8 7000) with the same 8.4" WQXGA Super AMOLED display.
