Since last year, due to the design of full-screen displays, front-facing cameras have gradually lost their place on the screen, leading to the emergence of pop-up cameras. This year, this design has also started to become widespread, with almost all major manufacturers wanting to adopt it. This time, Xiao E has selected four smartphones with pop-up camera modules for partners to thoroughly understand the principles behind these camera modules.
First, let’s take a look at the particularly special side-rotating pop-up structure front camera released by OPPO this year. The special feature is the asymmetric side-rotating structure adopted by Reno. The stepper motor is placed on the right side, and the side-rotating pop-up module is driven up and down by the stepper motor, completing the pop-up of the front camera. The most technically advanced part of the phone is the metal groove of this pop-up camera, which uses precision CNC cutting to ensure perfect fit.
Next, let’s take a closer look at the entire side-rotating pop-up module. The transmission component uses a small seven-tooth gearbox to reduce the noise of mechanical movement. The basic principle is similar to earlier modules. It still uses the stepper motor to provide upward thrust, but adds an axis.
This pop-up module actually includes not only the front camera but also the microphone, earpiece, front camera, and rear camera flash. The protective cover is attached with foam glue, and prying open the protective cover reveals the module locked in the groove, with the earpiece fixed by foam glue. The front camera’s ribbon cable is relatively long and integrates the microphone and flash module. The soft board has some bending space.
X27‘s front pop-up module is mainly divided into three parts: front camera, stepper motor module, and limit structure. The upper part of the motor module is the climbing device, and the lower part is the motor. The climbing device has a screw rod, a slide rail, and a push module. After the motor is started, the screw rod rotates to control the push module to move on the slide rail, thus achieving the rise and fall of the front camera. Disassembly requires removing screws and nuts from the fixed frame and motor, taking off the slide rod, and removing the spring and connecting ring. After that, the front camera and motor can be taken out. At this point, you can see that the internal support has a limit structure on both sides. The advantage of the spring structure is that it can act as a buffer when the camera rises and is subjected to external force.
The front camera module is not just a single camera; it is wrapped in a protective shell. The side also has a metal rod for lifting. The camera’s ribbon cable is relatively long and has some folding space.
Realme X
The pop-up module uses a pulse-type lifting method to control the rise and fall of the camera. The camera module consists of a plastic front cover, camera, and metal rear cover, with magnets and glue connecting the front cover to the rear cover. The camera is fixed to the rear cover with glue, and the spring is connected to the lifting module, allowing the camera to rise and fall freely.
The front camera module and its pop-up module are fixed to the front of the mid-frame with screws. By removing the screws, the front module can be taken out.
The front camera module also has a limit spring. The ribbon cable of the front camera is relatively long and has bending space.
OnePlus 7 Pro
The front pop-up camera module places the motor spring design on the left side, which is a buffer mechanism designed to prevent external pressure. The lower part of the motor module is the motor, and the upper part is the climbing device. The climbing device has a screw rod, a slide rail, and a push module. After the motor is started, the screw rod rotates to control the push module to move on the slide rail, thus achieving the rise and fall of the front camera.
After looking at the above two phones, we can see that the pop-up front cameras all come with a protective shell, and the protective shell sides have lifting rods connected to the lifting module. The OnePlus 7 Pro is no exception; the front camera also has a lifting rod fixed to the module. The ribbon cable of the front camera is also relatively long and can bend.
Conclusion
After watching the pop-up modules of these four cameras, those interested in pop-up cameras must have gained some understanding of their structures. We can see that the pop-up modules use springs for limiting and buffering. The requirements for the soft boards are also quite high, needing to have certain flexibility to maintain extension during the lifting process. There are also many similarities, with some differences to fit the models. So, which one do you prefer?
