Samsung’s new patents in the field of folding and rolling devices

Samsung’s new patents in the field of folding and rolling devices There is no doubt that in the field of folding smartphones production, Samsung speaks first. Galaxy Z Fold3 and Z Flip3 are the latest models that this company has so far has launched Other brands – including Huawei, Motorola and Xiaomi – also products They have released the same to the market. Oppo Find N – which was introduced last week – the first phone The folding is Oppo. In the meantime, smartphones with a rollable screen is a new field that manufacturing companies have recently focused on designing, and even a few prototypes – such as Oppo x 2021 and TCL Fold ‘n Roll – have also presented . In this regard, by registering two other patents, Samsung showed that it is not ignorant of this field either.

Samsung’s patent for a phone that can be rolled in two directions

As if the concepts of foldable phones and Rolling was not enough for Samsung, because Samsung has decided to register a patent for a sliding device, which can be moved horizontally or vertically depending on the type of use. This patent was submitted to the World Intellectual Property Organization (WIPO) on May 21, 2021 (May 31, 1400) and finally on Thursday, December 16, 2021 (Azar 25, 1400) with the title “Electronic device including a display with multiple modes and methods to control it.” Released. The Dutch website LetsGoDigital is the first reference to this patent. Galaxy Z Fold smartphone with dual slide function”>observed.

In this patent Samsung examines the possibility of making a device whose display It is possible to expand both from the edge of the phone and from above. The images published with this patent are self-explanatory. In these pictures, a modern Samsung phone can be seen, which has curves on the right edge and the top edge, which gives it a unique appearance. This phone is almost full-screen and only a thin edge of the frame can be seen at the bottom.

As said, the most important feature of the phone discussed in this patent is that it can It expanded the display both horizontally (from the right edge) and vertically (from the top). Now, it is up to the user to choose whether to extend the display in both directions or only in one direction. By pressing the button on the left edge of the phone, the process of expanding the screen begins. Now, from which side the expansion is, it depends on the movement of the user’s finger in which direction he touches the screen in a sliding manner. According to Samsung, in case of horizontal expansion up to 30% and in case of vertical expansion up to 25%, the total screen area will be increased.

In the upper right corner, a selfie camera can be seen, which is embedded in the frame itself. The location of this camera is very important, because the screen cannot be enlarged or reduced at that point. Therefore, it is the selfie camera that determines the angle at which the display will be extended.

It should be noted that when the display of this device expands (whether horizontally or vertically), we will face a new form factor, which naturally creates new options for the user. Another interesting point is that, according to Samsung’s imagination, this rollable smartphone will also have the ability to rotate 180 degrees (after which the screen protruding from the body will be placed on the opposite edge). In other words, the part of the screen that protrudes from the top of the phone suddenly turns downwards, and after that, the user interface adapts itself to the available screen.

Experts believe that The Samsung design in this patent could be an advanced version of Flex Mode (in Galaxy Z Fold and Galaxy Z Flip). This new form factor can be used to open an additional app (like a messaging app). In this way, the user can easily switch between different applications with a glance (without the need to close the application). The display of operational elements (such as a virtual keyboard or calculator) is also another use mentioned for this type of design. In the following, several different scenarios of the discussed phone applications are depicted:

Samsung’s patent for a foldable and rollable device with an adjustable angle

This Patent – entitled “Electronic device with sliding and folding functions” on December 16, 2021 (25 Azar 1400) at WIPO published – describes a device capable of simply bending a folding display It is not enough. At first, we mention the aspect of its rolling, which, except for prototypes, has not yet been seen in any other device. The main mechanism is that you take one side of the display and pull it along with a part of the lower body – which plays the role of the handle – and then more part of the same display panel that was previously rolled into the body of the device. pulls out This way, when you need more screen area, you can easily pull it out of the device and when you don’t need it, the screen is rolled inside the device.

Maybe Conceptually, the display mechanism of this device seems simple, but due to structural and mechanical reasons, implementing this concept will not be easy. Perhaps the most interesting and at the same time the most complicated part of this design is how to fold the display. It seems that the part of the panel that is rolled inside the device by a hinge under it is divided into several pieces.

Apparently when the display is pulled out of the device Or you roll it inside, this hinge can be folded along with other components of the display set and for this purpose it uses 4 rollers (this design is very similar to Samsung folding devices). This mechanism allows that part of the screen to be separated from the body of the device at an angle.

According to the experts, it can be assumed that this hinge – just like the current folding devices – has a twist-axis structure that can provide more freedom of action when adjusting the angle. Not to mention, it seems that in this type of design, the display cannot be completely closed (with or without the air gap above it). Apparently what you can do is move the angled display a bit further in or out (depending on how far you’ve rolled the other part of the display).

Maybe The biggest question that comes to mind is what this type of design can be used for. The philosophy of that part of the screen that rolls is somewhat understandable, but Samsung aims to consider The screen that is placed on it at an angle from the previous screen is not very clear.
