Fast Technology reported on September 18 that Huawei's three folds suddenly appeared, showing Huawei's strong technology research and development and exploration in the field of folding screens, but other manufacturers actually have relevant technical layouts.
According to the information published by the State Intellectual Property Office on September 3, a design patent for a "mobile phone and its main body" of Xiaomi was announced, which is the design scheme of Xiaomi's three-fold mobile phone.
The authorization announcement number is "CN308817132S", and the application date is December 21, 2022, and there are two schemes, but the whole is the same Z-shaped folding method as Huawei.
The Xiaomi Trifold in the sketch is also slim, with a horizontal rear camera, a total of three cameras, and an LED flash.
However, it is possible that this model does not exist, but Xiaomi is carrying out relevant technology research and development and patent reserves in three folds.
It is also worth noting that in fact, as early as the beginning of 2019, Lin Bin, co-founder of Xiaomi, announced Xiaomi's first dual-folding smartphone, which is actually similar to today's "three-fold" concept.
It's just that at that time, it was more about the technical reserve of the folding screen, and the machine was mostly exposed for the purpose of showing off skills, and the folding method was relatively chicken ribs, which was difficult to use normally.
At that time, Lin Bin introduced that Xiaomi's dual-folding mobile phone has overcome a series of technical problems such as flexible folding screen technology, four-wheel drive folding hinge technology, flexible cover plate technology and MIUI adaptation, which should be the world's first dual-folding mobile phone.
