Some smartphones that can be used on both the back and back of the smartphone have appeared in the past, but all have disappeared quickly.Because it was not sold in Japan, many people would not know its existence in the first place.The back side could not be worn in the display area, and there was no merit that the back side could be used in the first place.
However, it is troublesome to turn the body upside down to see the notification, such as when the smartphone is turned over and put it on the desk.So a smartphone with a small sub -display on the back gradually came out.For example, Xiaomi's "Mi 11 Ultra" is 1 next to the camera.Equipped with a 1 -inch small sub display, you can usually display the date, etc.
Looking at the back of the mi 11 Ultra, the sub -display is lined up without any discomfort, and it seems natural that there is a display there.However, there are smartphones that are mounted on the back display, and with a slightly more attractive design."Ticktock" on the back of the back, which is on sale from UNIHERTZ, which has some unusual products, such as smartphones with keyboards in Japan..A 3 -inch circular display is embedded.The left and right are decorated like a watch belt, and when you display the analog clock, it looks as if the clock is stuck on the back of the smartphone.
Although it is a very unusual design, this is actually implemented by a Chinese "8848" manufacturer first.The 8848 offers ultra -luxury smartphones and has been selling hundreds of thousands of yen for several years.The back of the body is made of genuine leather and crocodile leather, and the power button that is operated many times is made of expensive natural materials, such as ruby embedded.Speaking of luxury smartphones, manufacturers called "Vertu" have been producing products for more than 10 years, but Vertu is currently being developed mainly in China.A product called a luxury smartphone is required in China.
The advantage of built -in sub -display on the back of the smartphone is that it can be operated to some extent with the main unit turned over.The most convenient is that when you get a phone call, you can check the name displayed on the sub -display and touch the sub -display as it is.Because you don't have to turn the body over each time, you don't have to respond to unnecessary urgent calls, such as invitation calls.
Also, if you display a preview on the sub -display when the camera is started, you can take a self -portrait using a high -quality main camera on the back.Generally, the main camera is higher than the front camera, so you can shoot a selfie in a slightly darker room or a slightly darker place at night to make it brighter and beautiful.
The back sub display has a rectangular shape like Xiaomi, but as described above, it can be designed like a wristwatch or smartwatch on the back of the smartphone as described above.The back of the smartphone is designed to differentiate each company with the camera part design, but by displaying a clock face on a circular display, it can be designed to embed a watch (like).This will be very attractive.
There are still only a few models with sub -displays, and the functions that can be used are limited.However, it should be wasteful to keep the back of the smartphone a "just a board".One of the smartphones from Japan, BALMUDA's "BALMUDA PHONE" is a product equipped with a basic function, but it has an indicator light on the back and it blinks if there is a notification.Although it is only one light, this notification is quite convenient when the body is turned over.
The movement with a sub -display on the back of the smartphone is likely to be around Samsung, which has a display subsidiary.Speaking of which, folding smartphones such as Samsung are equipped with another display that can be displayed when closed, in addition to the foldable Fol Double display.A vertical folding smartphone is equipped with a small sub -display on the back when closed.The movements that are equipped with multiple displays on smartphones to link and use each have already begun on folding smartphones.
The vertical folding smartphone "P50 POCKET" on sale from Huawei has two circular displays on the back, making it an analog clock face on one side.A circular sub -display where you can enjoy analog -like watch design with the latest IT product smartphone.It may be mounted on smartphones that are conscious of fashion and design.
