OPPO X 2021: WE TESTED THE SMARTPHONE WITH AN EXTENDABLE SCREEN

Oppo has a long tradition with different form factors than usual. From the rotating camera of the Oppo N1, presented in 2013, to the particular Find X that we tried in 2018, the Chinese house has never backed down in the face of apparently impossible projects. It is therefore no coincidence that, in the field of folding smartphones, Oppo has decided to enter in a different way from the others, proposing a phone with an extendable screen .

Oppo X 2021 is a truly unique device, at present not yet complete and with technical characteristics to be defined, but its diversity lies in the display, which we tested live and which impressed for the future potential of this technology.  healthnutritionhints

A concept phone or a real product?

Before talking about our brief experience with Oppo X 2021 it is good to clarify that what we have tried is practically a prototype . Not so much in the technology behind the display as much as in the general specifications, since there is no real list of the technical characteristics of the device. We are therefore not facing the definitive version that could arrive in stores within the year, but rather a device created to show the potential behind the extendable screen to the press and commercial partners.

But will Oppo X 2021 really arrive in stores? For now there is no certainty, however the name of the product leaves some hope in this sense, as the year is clearly indicated.

Obviously we are talking about a very particular and high-cost device, which characterizes all smartphones released so far with a flexible display.

However, Oppo has created something different than what was seen with the Galaxy Fold 2 and in the review of the Huawei Mate Xs , focusing on a particular form factor, confirming that flexible screens will make an important contribution in the coming years, putting in the hands of companies the ability to create unique products, just like this Oppo X 21.

A leaflet different from all

Flexible screen technology allows manufacturers to create smartphones other than the ones we have used to date. Samsung with its Fold has protected the flexible screen by closing it inside a rigid structure; always the Korean house then brought this technology into the Galaxy Z Flip, bringing the clamshell design back to life, the same thing Motorola did with the RAZR. Huawei has instead opted for a more extreme solution, placing the flexible screen directly outward with its Mate Xs.

Oppo X 21 is instead the first extensible smartphone that we have tried , a different solution but which confirms once again how this technology can lead to the creation of more and more particular devices.

Just a slide or double press on the power button of the phone to activate two small motors that extend the screen from 6.7 to 7.4 inches . It is a very complex system to implement, especially for a product that, hopefully, is not a simple prototype. The mechanism has been designed to work up to 100,000 activations, Oppo estimates a duration of just over 5 years in case of normal use, while in case of greater use of the mechanism it drops to 2-3 years. As anticipated we have no technical data but the resolution of the panel varies from 1175x2592 pixels up to 1785x2592 pixels, based on when it is closed or when it is open.

The use of a screen of this type, Oppo tells us, allows not only to have an extendable display but completely modifies the internal structure of the smartphone , paving the way for new solutions regarding cameras, battery and all the components that they go to dial a telephone.

The mechanical system that regulates the extension of the screen is formed by two motors that apply a constant force on the panel , this allows it to always be in tension, thus avoiding the small folds that we have seen in other flexible phones. Even during the extension phase of the display the voltage remains constant, there are no moments in which the screen loses its shape.

Particular is also the internal support structure that keeps the flexible OLED panel in position, which changes its shape according to the use of the smartphone, and the frame that surrounds the screen, with a sliding system that adapts the body to the state of the phone, whether open or closed.

Watching the mechanism in action live is truly spectacular, the sound it generates is minimal and even the interface has been designed to perform at its best on a configuration of this type. Already at this point of development, far from definitive, we have observed a good integration of the extensible screen in the Oppo ColorOS interface , which adapts the contents in real time without interrupting the playback.

An example could be the viewing of a video, which is not interrupted by the panel extension, but managed through an elegant transition performed during the expansion of the display, the same thing happens with web pages.

There are several optimizations made to ColorOS to better exploit the extendable technology, from the application of the camera to multitasking the options are not lacking.

At this point all that remain is to understand when Oppo intends to develop this prototype into a commercial product. The "2021" in the name suggests that we could see it in stores already this year, thus enriching the panorama of flexible smartphones with a completely new form factor.
