The device consists of a flexible layer, a protective layer and a touch sensor and has a support thickness. It is manufactured in liquid metal, or a shape memory alloy such as nickel-titanium or by amorphous metal. Its surface is made of an Amoled type material, LCD, graphene, indium tin oxide, OLED, micro-LED or other technology to come.

Description

Extendable screen

Technical area

The present invention will make it possible to combine on the same device the functionalities fulfilled today by different materials. It is a screen that can stretch until it reaches the size of a cinema screen in order to fulfill the uses of all intermediate-sized electronic devices. Basic in size, the patented device will go through several stages before reaching its optimal size (First in the state of a telephone, then that of a tablet, then that of Television, finally in Large Cinema screen)

State of the art

The existing electronic communication devices are dedicated to a function and have a size adapted to their use:

The smartphone, smartphone, fits in the pocket. Its capacities in terms of memory and processor power are less than those of other devices.

The electronic tablet has a screen approximately the size of an A4 sheet. It does not have great computing power but is mainly used for reading documents or browsing the internet.

The personal computer is more powerful, which makes it possible to install complex programs there, which require a lot of memory, and significant capacities in terms of computing power and screen management. This is the case of game applications, for example, which are very resource intensive. Its use in the context

-2professional also requires a larger screen than the tablet (at least 13 inches diagonal).

The television is reserved for broadcasting images, which imposes a screen size of several tens of inches diagonally, for the comfort of the view.

The cinema screen is even larger.

These different devices are currently separate and must be acquired independently of each other.

Description

The invention aims to group the devices listed above (smartphone - tablet personal computer - television - cinema screen) in a single device, the size of which will be adjustable according to the use that will be made of it.

The author of the present invention has therefore imagined the device of this patent, of which he has defined a certain number of objectives such as below:

According to the preferred embodiment of the invention, the device (1) is intended to fulfill all of the communication and data processing functions, such as:

- Telephone calls, sending and receiving SMS-type messages, sending and receiving emails;

- Surfing the Internet ;

- Execution of applications or programs of all types (games, office automation, professional software ...);

- Download and broadcast of music or video;

- And any other use to come.

According to the preferred embodiment of the invention, the device (1) is made of a material having elasticity properties which allow it to stretch to be used and to retract after use (2). The user will stretch the device until it reaches the size suitable for the use they wish to make of it. The device (1) will be made of a shape memory material in order to keep the chosen size once it is stretched.

According to another embodiment of the invention, the device (1) is made of a flexible material in order to roll up on itself (4) and / or to fold up (3) for transport and to be unroll and / or unfold for use. The user will unroll / unfold the device until he obtains the size suitable for the use he wishes to make of it. The device (1) will be made of a shape memory material in order to keep the chosen size once it is unrolled and / or unfolded.

According to the preferred embodiment of the invention, the device will be supplied with energy by a wired connection to the electrical network, or else by an autonomous energy production means (solar energy collectors, by pressure, by induction, or anywhere else to come).

According to the preferred embodiment of the invention, the device will be composed of a flexible layer, a protective layer and a touch sensor. It will have a support thickness.

According to the preferred embodiment of the invention, the structure of the device will be constituted by metal liquid, or a shape memory alloy such as nickeltitane or by amorphous metal.

According to the preferred embodiment of the invention, the surface of the device will be made of a material of the Amoled type (active-matrix organic light-emitting diode, or active matrix with organic light-emitting diodes), LCD, graphene, electrode in indium tin oxide, OLED, micro-LED or any other new technology that will be developed in the future.

-4The figures appended to this document present:

- A device that deploys by extension (Fig. 1);

- A device which unfolds by unfolding (Fig. 2);

- A device which unfolds by unfolding (Fig. 3);

Conclusion

The present invention is innovative because it does not appear in existing equipment or in patents already filed. It is interesting because it allows the user to permanently have all the communication and data processing devices he may need. A single purchase is necessary to meet all professional and leisure uses. Transport and storage are facilitated by the small size of the device when it is not in use.

This invention can be useful in the professional world within the framework of displacement of collaborators outside the company. They will therefore always have the equipment necessary for a presentation.

Advances in technology make it possible to manufacture a device as described above.

The present description, with regard to the appended drawings and subjective descriptions by way of nonlimiting examples, will make it possible to understand how the invention can be envisaged and put into practice in the years to come, without however knowing the materials and accessories of the future can improve this patent.
