Apple reportedly plans to launch three OLED-based new iPhone devices in 2020 available in 5.42-, 6.06- and 6.67-inch sizes, respectively, according to sources from Taiwan's handset component supply chain.

But for 2019, Apple will continue to roll out three models following the screen technologies and sizes of the three phones launched in 2018: two OLED models available in 5.8-inch and 6.5-inch screens, and a 6.1-inch LCD model, the sources said.

Additionally, the 5.42-inch model to be released in 2020 may come with either Samsung Display's Y-Octa or LG Display's TOE touch technology, indicated the sources, noting that both touch solutions promises to trim down the display cost.

Y-Octa is an advanced flexible AMOLED display technology that removes the film substrate and allows the touch circuit to be directly patterned on the film's encapsulation layer, making the display thinner, indicated the sources.

Judging from technology ability, Samsung Display is likely to remain the primary OLED panel supplier of Apple in 2020, and it remains to be seen whether LG Display or BOE Technology can obtain OLED panel orders from Apple, the sources said.

With regard to iPhone sales in 2019, the sources estimated Apple is likely to ship 80-82 million iPhone devices in the first half of 2019 and about 180-190 million units for all of the year.
