Description

ELECTRONIC DEVICE WITH AN ELASTIC STRETCHABLE DISPLAY DEVICE

FIELD OF THE INVENTION

The subject matter generally relates to an electronic device with an elastic stretchable display device and a method of stretching the display device.

BACKGROUND OF THE INVENTION

Many electronic devices used for the capturing and consumption of content, such as TV, tablets, smartphones, digital cameras, media players and others, are equipped with a screen which is used to display the content, and in some cases - in which such screen is a touch screen— to serve as an input unit which enables the user to control the operation of the electronic device or interact with it.

The technologies applied in such display devices can vary, and may include elements and characteristics, such as flexibility, transparency, resistance, and others. Companies such as Samsung and Apple use flexible and transparent displays to provide electronic devices that can fold, bend, curve, become transparent and so on. Such prior-art devices may be equipped with more than a single screen unit, or devices in which the flexibility of the display enables configuring the device in such manner it appears as if there is more than a single display (for example, by bending part of the display).

The use of such flexible display, or the use of several displays, enables various configurations of such electronic devices, in such manner that the user can change the available display by unfolding or folding a part of the display, by adding additional displays, etc. However, all these type of solutions are limited by nature. For example, a roll able display requires storage means to store display elements (if the display in dynamically flexible). Therefore, there is an opportunity and need to present a different display type.

SUMMARY OF THE INVENTION

In some cases, switching between the first state and the second state is performed responsive to a physical action by a user of the mobile electronic device. In some cases, switching between the first state and the second state comprises changing a ratio between two edges of the display device.

In some cases, switching between the first state and the second state is performed responsive to a predefined command sent from the processor. In some cases, the predefined command from the processor is affected by an application used by a user of the mobile electronic device.

In some cases, the display device is kept in the first state or the second state for a predefined period of time or until an occurrence of a predefined event. In some cases, the predefined event is associated with an indication concerning a battery status.

In some cases, the mobile electronic device further comprises a physical container containing a material configured to change a temperature of a physical element of the mobile electronic device, wherein the display device switches between the first state and the second state responsive to change in the temperature of the physical element.

In some cases, the display device is stretched to a first predefined direction responsive to a first predefined action and stretched to a second predefined direction responsive to a second predefined action.

In some cases, the mobile electronic device further comprises an input unit, wherein the predefined action is inputted by a user of the mobile electronic device on the input unit.

In some cases, the input unit is located in the area added when stretching the display device.

In some cases, the mobile electronic device further comprises a size sensor unit for sensing the environment of the mobile electronic device. In some cases, the predefined action is captured by the size sensor unit, and the display device is stretched or shrunk accordingly.

In some cases, the size sensor unit senses whether there is an external need to shrink the display device or a physical possibility to stretch the size of the display device and transmits the sensed information to the processor.

In some cases, the mobile electronic device further comprises an elasticity size sensor unit for monitoring an elasticity property of the display device when stretched.

In some cases, the change of the size of the display device results in changing a physical property or shape of a display surface of the display device.

In some cases, the physical property is changed in a predefined segment of the display device.

In some cases, the change in the physical property of the display surface comprises creation of a bump or a recess on the display surface. In some cases, the bump or the recess is created responsive to a predefined event. In some cases, the predefined event is information or an application activated on the display device.

In some cases, the mobile electronic device further comprises a second display device, wherein the display device and the second display device create a three dimensional shape. In some cases, the display device is stretched over the second display device. In some cases, the content in the display device interacts with content of the second display device.

In some cases, die mobile electronic device further comprises a frame surrounding at least a portion of the display device, said frame is made of an elastic material. In some cases, the display device is located on a steering wheel. BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION

The subject matter discloses an elastic display device capable of being stretched, stretched, at least partially. The display device may be part of an electronic device, such as a laptop, tablet or smartphone, or operate as an individual unit.

Figures 1A and IB show a display device in a stretched state and shrunk state, according to exemplary embodiments of the disclosed subject matter. Both figures show a display device 100 in a shrunk state, having a top edge 110, right edge 115, bottom edge 112 and left edge 105. In the stretched state of figure 1A, display device 150 comprises a top edge 120, right edge 130, bottom edge 135 and left edge 125. It can be seen that left edge 125 is of the same size as left edge 105 of the shrunk state, while the other edges have been stretched. As right edge 130 is bigger than the right edge 1 15, top edge 120 forms a slope from the bottom edge 135.

Figure IB shows a stretchable display device, such that when stretched to a stretched state 180, the display device comprises top edge 165, right edge 170, bottom edge 160 and left edge 168. It can be seen that at least two of the edges, top edge 165 and bottom edge 160, are not straight lines.

In some cases, the stretchable display device may be flexible, may be transparent, may include touch sensing means, unit may include sensors and additional computerized or mechanical modules. The stretchable display device may be produced from elastic materials, and may include a component or material configured to maintain the display device in the stretched and/or shrunk position. The material may be a coating material coating at least a portion of the display device. The component or material configured to maintain the display device in the stretched and/or shrunk position may be sensitive to a predefined condition, such as change in temperature, injection of voltage, exposure to light or to any chemical material, such that the material becomes flexible in accordance with the predefined first condition certain temperature range and becomes rigid in accordance with the predefined first condition. The component configured to change the state of the display device from a shrunk state to a stretched state or vice versa may include means to heat and/or cool the display device or predefined portions or elements of the display device.

Figures 2A and 2B show a display device stretched when its user pulls a portion of the display device, according to exemplary embodiments of the disclosed subject matter. Figure 2A shows a display device in a shrunk state 200, comprising a top edge 212, right edge 220, bottom edge 215 and left edge 210. The user's fingers 230 touch a predefined portion 222 in the display device. The predefined portion 222 may be a corner of the display device 200. Responsive to the user's fingers 230 pulling the corner 222, the display device switches to stretched state 265, comprising top edge 240, right edge 260, bottom edge 250 and left edge 245. It should be noted that the top right corner 242 is higher in stretched state 265, which makes right edge 260 longer. Similarly, top edge 240 and bottom edge 250 are also stretched.

Figure 2B shows an elastic display device in shrunk state 275, comprising top edge 282, right edge 286, bottom edge 280 and left edge 284. The user's fingers 270, 272 touch two predefined portions of the display device 275, which are the middle section of the right part and the left part of the display device. Switching from shrunk state to stretched state may result only when the user pulls the predefined area by applying force which is higher than a predefined threshold. When in stretched state, the display device 288 comprises top edge 292, right edge 295, bottom edge 298 and left edge 290. The user may push the display at the corner or the side to switch the display device to shrunk state.

Figure 3 shows a user interface enabling a user of a display device to switch the display device from shrunk state to stretched state, according to exemplary embodiments of the disclosed subject matter. At first, the display device is in shrunk state 300, comprising top edge 315, right edge 318, bottom edge 319 and left edge 310. The user's finger 340 points at or touches a predefined area 330 in a stretching area 345, the display device switches to stretched state 360, comprising top edge 365, right edge 375, bottom edge 370 and left edge 368. The shape and size of the display device in the stretched state 360 may vary according to the specific point the user's finger 340 touches in the stretching area 345. For example, if the user's finger 340 touches the right end of the extension area 345, the display device will stretch to the right. If the user's finger 340 touches the top left corner of the stretching area 345 for more than 2 seconds, the top left corner will stretch in more than 2mm. The set of rules used to determine how to switch the size of the display device from shrunk state to stretched state may be stored in a storage of an electronic device connected to the display device.

Figure 4 shows a display device comprising sensors used to switch the display device from shrunk state to stretched state, according to exemplary embodiments of the disclosed subject matter. At first, the display device is in shrunk state 400, comprising top edge 412, right edge 415, bottom edge 418 and left edge 410. The sensors detect presence of an object near the display device 400 and determines a need to switch to stretched state 440 according to the detected information. In some cases, the sensors detect a predefined gesture which generate the switch to the stretched state, or a switch back to the shrunk state. When in stretched state, the display device 440 comprises top edge 452, right edge 455, bottom edge 458 and left edge 450. The sensors may detect presence of objects in a limited area 470, for example presence of a user's palm 460 over the display device 440 in the limited area 470. The sensor may be temperature sensor, volume sensor, proximity sensor, touch sensor or any other type of sensor desired by a person skilled in the art.

The electronic device and/or display unit may include sensors that may detect at least one finger movement, and translate the detected movement into a direction in which the display device is stretched or shrunk. For example, the user may touch the device in the middle of the display device with all his fingers of one hand grouped together, and when expending the fingers (i.e. opening his hand) while touching, this will indicate the device to stretch the display device in all directions. Similarly, the display device may be switched to a shrunk state responsive to detection of fingers' movements from an open position to a grouped position. The sensors may include at least one camera that can detect such movements.

The sensor of the electronic device connected to the display device may sense the surroundings of the display device, such that the display device may stretch, expand or collapse according to the sensed data. For example, a tablet may be leaned on a wall and a sensor may be used to detect available free wall size around the device, and expand the display device. In another exemplary embodiment, a user may want to place such tablet device in a front pocket of his pants. Said sensors may detect the pocket entry size, and reduce the device size accordingly.

Figure 5 shows sensors detecting user's gestured when switching the display device from shrunk state to stretched state, according to exemplary embodiments of the disclosed subject matter. When in shrunk state, the display device 510 comprises a sensor 515 for detecting movements or gestures in a predefined area, for example defined between lines 520 and 522 projected from the location of the sensor 515 on the display device 510. That is, the sensor 515 may not detect movements outside the predefined area. In some point, the sensor 515 detects the user's palm 530 in the predefined area. When the user's palm 530 performs a predefined movement or gesture, the sensor sends a command to a control unit of the display device 510 to switch to stretched state 550. The gesture may be opening the user's palm 530, for example by increasing the distance detected between the user's fingers. When in stretched state, the display device 550 also comprises a sensor 555, which may be the same sensor as sensor 515. In some cases, the display device 550 in the stretched state comprises more sensors, for example in the areas not covered in the shrunk state. The sensor 555 detects movements in a predefined area defined by lines 560, 565 projected from the sensor 555. Movement of the user's palm 570 may result in switching back to shrunk mode, or change the size of the display device otherwise.

The display device may include an elasticity sensor configured to detect the elastic pressure status of the stretchable display. The elasticity sensor may be integrated into the display device. The elasticity sensor may be used to monitor the extension direction, or to monitor if the extension has reached the limit available to the display device, according to information stored in the electronic device. The electronic device may include an indication unit to indicate if and to what extent can the display device be stretched or shrunk. For example, to indicate that the display device can be stretched by 3cm to the right and 0.4cm to the top, and can be shrunk by 0.8cm from the left.

Figures 6A and 6B show the display device comprising bumps or dents responsive to switching from one state to another, according to exemplary embodiments of the disclosed subject matter. Figure 6A shows a display device 610 comprises bumps 612, 616, 620 and 624 projected from a display surface 611 of the display device 610. Figure 6B shows a display device 640 comprises dents 650 and 655 projected from a display surface 645 of the display device 640.

The elastic component of the display device may be used to protect the display device from breaking, tearing or otherwise defect, by sensing when an object is hitting the display, and enabling the display to "dent" and the hitting point.

The elastic component may create said bumps and/or dents to alter the surface of the display to accommodate a software application. For example, in a maze software application game, the display device may be altered in such manner that the maze is not only visually displayed, but also materializes on the surface of the display device, by bumps or dent channels, or both. The bumps or dents may have gradient elements, in such manner that the gradient elements "rise" and "fall". The game may use a ball or another object that can be sensed when touching the display device, and the user may need to move it the ball in the maze. In another exemplary case, only a portion of the display unit may stretch or shrink, in such manner that specific characters of forms will protrude or otherwise sensed on the display surface. For example, said extension and/or shrink actions may generate protrusions or bumps in the shape of numerical or alphabetical characters, enabling the user of the display device to sense the character shape and its location on the display device, thus operate the display device without looking at it.

The electronic device may include a computerized unit configured to adapt the displayed content to a new shape and/or size after switching from one state to the other. The electronic device may include a computerized unit configured to allocate different display to different types of content and/or software applications when the display is stretched or shrunk.

The display device may switch from shrunk state to stretched state automatically according to a selected software functionality, or according to content displayed on the display device. For example, a user may want to use his tablet as a phone, activate a dialer application and the device may apply means to "shrink" the display to a smaller size. Switching tlae size of the display device may be predefined by the user, may be automatically configured, or may be ad-hoc per application, in real-time according to an input from the user.

In another such preferred embodiment, the user may activate a book reader software application in such electronic device, when the display is at shrunk state. Upon activation of said book reader software application, the display device may automatically expand or extend, in such manner that it will best fit a reader size according to a predefined size. Similarly, when a user wishes to watch a movie, the display device may expand to reach a display size and shape that fit a movie, for example 9: 16 display ratio.

Figure 7 shows the display device comprising a control panel when switched to a stretched state, according to exemplary embodiments of the disclosed subject matter. In yet another preferred embodiment of the invention, when a user wants to use a gaming application via the electronic device, selected areas of the display device may be stretched in such manner that the game's touch control buttons will be located in those stretched areas. When the display device is in shrunk state 700, comprising top edge 720, right edge 725, bottom edge 715 and left edge 710, the user activates a computerized application that requires control panel in two ends of the display device. Such activation may be via a vocal command or via an input unit, such as a touch screen on the display device, keyboard and the like. Responsive to activation of the computerized application, the display device is switched to the stretched state 740, in which two additional areas 750, 760 are added to the display device, extending from a bottom edge of the display device. The top edge 745, right edge 748 and left edge 742 remain unchanged. The left area 760 comprises one or more virtual keys 762, 765 used by the user's palm 768 to input commands or information into the electronic device while the computerized application is activated. Similarly, the right area 750 comprises one or more virtual keys 752, 758 used by the user's palm 755 to input commands or information into the electronic device while the computerized application is activated. In some cases, the stretched areas 750, 760 may comprises indication units that display indications on the stretched areas 750, 760 according to content or situation associated with the computerized application.

Figure 8 shows a three-dimensional object having a display device switched to a stretched state, according to exemplary embodiments of the disclosed subject matter. When the object is in shrunk mode, the object comprises front surface 810 defined by front top edge 814, front right edge 813, front bottom edge 812 and front left edge 811. The object in the shrunk state also comprises top surface 815 and right surface 820. The top surface 815 is defined by front top edge 814, rear top edge 816, top right edge and top left edge. The right surface 820 is defined by front right edge 813, right bottom edge 817, rear right edge and top right edge. The display device of the subject matter may be in one of the surfaces of the electronic device in the shrunk state, for example in the top surface 815, or in two or more of the surfaces of the electronic device. When stretched to the stretched state, the electronic device comprises front surface 860, right surface 840 and top surface 850. The front surface 860 is defined by front top edge 853, front right edge 843, front left edge 861 and front bottom edge 865. The top surface 850 is defined by front top edge 853, top left edge 852, top right edge 844 and top rear edge 851. The right surface 840 is defined by top right edge 844, right bottom edge 841, front right edge 843, and rear right edge 842.

The electronic device may include means to detect battery consumption of the device in general, and the display device in particular, and to stretch or shrink the display to optimize power consumption based on used applications. The three-dimensional device may be created using more than one display units. The three-dimensional device can be created by using a flexible bendable/foldable display device.
