The new Smartphones Redmi K20 and K20 Pro from redmi, have as is known an emerging mechanism for Selfie camera, and enabled Xiaomi to remove all forms of screen slot from the devices.
Όas is logical, for these mechanical characteristics, there are usually fears about its durability. Xiaomi, based on its claims, built this camera mechanism to withstand up to 300.000 uses (pop-up & pop-down) without any problems.
Statistically and with a reasonable use of the phone, this translates into a life cycle much larger than the life cycle of the phone itself. Xiaomi has shared more details about this mechanism, apparently to fully convince those in doubt.
The Redmi K20 Series Selfie Camera features a built-in rail design that uses a spiral motor to raise and lower the camera. It can reveal the camera in 0,8 seconds and has 6 custom lifting sounds. The camera lens cover is made of sapphire, resistant to wear and scratches, and offers stronger protection.
How the spiral stepper motor works
From the K20 and K20 Pro Pro teardown diagrams, it can be seen that to resolve the collision between the front camera and the full screen without rim, it uses an electric telescopic structure and the crucial element to achieve this design is a spiral stepper motor. .
The principle of operation of the spiral stepper motor is similar to simple screwing: the coil can be screwed down in a clockwise direction and unscrewed counterclockwise.
The reason why a spiral stepper motor is used to perform the lifting function, instead of the straight-pass method, is mainly due to the fact that the spiral stepper motor is easier to control and its operation is more stable.
Fall protection
To prevent the camera from being accidentally dropped, the K20 and K20 Pro use the special mechanism and software to protect the pop-up camera. The camera will retract quickly when dropped, and the inside has a spring-loaded device for protection.
The K20 and K20 Pro have a built-in three-axis gyroscope to detect violent movement, and combined with a second sensor inside the phone, it will force the camera to fold very quickly, with the whole process completed in 100ms.
At the same time, to prevent damage to the camera caused by the user pushing the camera when lifted, the K20 and K20 Pro are internally protected by spring devices and equipped with a dual magnet calibration chip to feel the pressure exerted on the camera .
We will not go into more detail and technical descriptions of how the camera works and is protected, but from what we have read above, it seems that Xiaomi has done a good job with the whole mechanism.
The success of the implementation remains to be proven in practice, of course, and we will learn in time from all the new owners of the devices.
