Almost all smartphones with OLED displays released in the first half of 2021 had a diagonal of 6 inches or more, according to UBI Research. Specifically, 6- to 7-inch OLED phones hold 97.5% market share, up from 78% in 2018.
That’s 119 models out of 122 released in the first six months of 2021. The Asus Zenfone 8 is the only one to go below 6″ (just below it has a 5.9″ screen”), the Sony Xperia 10 III is exactly at 6.0″. At the other end of the scale are the Xiaomi Mi Mix Fold and the Huawei Mate X2, which are the only models with 8.0-inch OLED panels. There were no 7″ models (the Z Fold3 will fall into this category for H2 stats).
The majority of phones (64 models or 52.5% share) had a pixel density between 400 and 500 dpi, followed by 48 models with screens below 400 ppi. Only 10 dared to venture above 500 ppi and the Sony Xperia 1 II dominated the charts with the 643 ppi density of its 4K class screen (technically, the 1 II was released last year, so we don’t know why it’s included in the Stats).
Most models (88.5%) had a screen-to-body ratio of 80-90%, with a few (11.5%) exceeding 90% StB. There was no phone where the OLED screen occupied less than 80% of the front panel. The phone with the highest StB ratio – 94.1% – was the Huawei Mate 40 Pro 4G.
Finally, the selfie cameras. The majority of models (103) have a puncture hole, a few (13) have a notch and even less (6) place the camera on the bezel. There are no Under Display cameras in this list as the only one to date (Axon 20 5G) was launched last year and the new one (Axon 30 5G) arrives later this month.
