99% ultimate screen ratio + invisible screen fingerprint - DOOGEE MIX 4 real phone(part 1)

I remember that at the MWC 2018 exhibition, the black technology's vivo APEXs, such as Half Screen Fingerprint, Screen SoundCasting, and Lifting Lens, have been eye-catching. One of the most amazing is its three-sided narrow border full screen, 98% super high screen ratio gives it extraordinary visual impact. Today, another Chinese mobile phone brand that focuses on overseas markets has brought its new work, the DOOGEE MIX 4, and the new phone is also expected to surpass the vivo APEX full-screen concept mobile phone, sitting on the first screen to occupy the top of the mobile phone.

As we all know, our ideal comprehensive screen product is to put a series of components such as front camera, light distance sensor and fingerprint recognition sensor on the screen to achieve higher screen ratio. However, the technology development speed of the supply chain is far less than that of the product designer. At present, only the screen fingerprint sensor can be mass-produced, and the sensor such as the camera and the light sensor is still a problem to be solved.

So the product designer of the DOOGEE phone made a different change: since it is impossible to put all the sensors under the screen, simply make another panel to accommodate the remaining sensors. So we can see that this DOOGEE MIX 4 mobile phone is a common 5.99-inch 18:9 ratio full screen, but it does not have any sensor opening and reserved area. It is evolved from the three-sided narrow border design common in the current high-end comprehensive screen field. To the rare four-sided narrow frame design, the screen ratio has reached 99% of the other comprehensive screen mobile phones, and the visual effect is enough to describe it unparalleled. 

The DOOGEE MIX 4 uses a more common slide-type design between the two panels. The front is an 18:9 ratio four-sided narrow border "true" full screen, and the screen has a built-in fingerprint recognition sensor, in addition to the conventional fingerprint entry recognition. In addition, it supports financial-grade payment operations just like the vivo APEX. At the bottom of the screen is another panel that houses components such as the front camera, earpiece, and light distance sensor. The user can slide out the panel and slide down the hidden panel.
