With an 8 inch and 7.3 inch large screen respectively, Huawei and Samsung have greatly attracted the attention of mobile phone lovers.

Here is the comparison with these two foldable phones.

In order to keep up with the trend, Apple also announce that they are planning to create their own foldable phone – iPhone X Fold. 

According to Dutch industrial designer Roy Gilsing, iPhone X Fold is an inner foldable phone with a 1:3 aspect ratio outer display and a 2:3 aspect ratio inner display.  

Once the screen is folded, half of the monitor can be turned into a touchscreen keyboard.

The phone can be used as a mini-notebook. 

Throughout these three foldable phones, it is worth noting that they have a big thing in common, which is using OLED as the material of their screens.

But what is OLED?

OLED stands for Organic Light Emitting Diode, it’s a material which can be used to create digital display on devices such as mobile phone screens.

According to DSCC（Display Supply Chain Consultants）, OLED has been widely used in the mobile industry since 2016. It seems that OLED has gradually taken the place of LCD in the smartphone market. But what’s the difference between OLED and LCD?

It seems that the advantages of OLED far overweight LCD’s. No wonder why it becomes the favorite of mobile industry.
