DETAILED DESCRIPTION OF THE INVENTION

A removable device case (e.g., a phone case) is disclosed with a bistable display or a low consumption display (e.g., very low consumption) located on its rear side. In FIG. 5 shows a device with a monoblock form factor located inside its removable cover to form a device node. A device (such as a telephone) may be equipped with a battery. The case may be equipped with a battery. If there is a battery inside the device (for example, a phone), a charged battery inside the case can be used to charge the device’s battery. The user can disconnect the removable cover from the device when both the battery of the cover and the battery of the device are exhausted in order to connect another removable cover with a well-charged battery in order to charge the battery of the device or power the device. The user can have several removable covers so that he can replace the removable covers several times in order to recharge the device’s battery or power the device each time without having to connect it to a power source.

A connection (for example, an information connection) between a case and a device (for example, a telephone) can be realized using a wired connecting device or wirelessly, for example, using Bluetooth technology. A wired connection between the device and its removable cover can be realized using such a connection between the device and its removable cover, such as through the device port, for example, through a device compatible with the USB port, or a specialized device port. The connection between the device and its removable cover can be realized using such a connection between the device and its removable cover as through the port of the device, for example, through a dedicated port of the device. The connection may be wireless. A removable cover may provide a port that is configured to interoperate a port of a device that is not available when the device is attached to a removable cover. Said interoperability may be a wired interoperability or a wireless interoperability.

According to one example, the device assembly comprises a device and a removable case for the device. The device may contain external elements for electrical contact. The removable cover may contain external elements for electrical contact. The device and the removable cover may include mating guide surfaces that are arranged to guide the removable cover to a proper position for connection with the device. One of the device and the removable cover may contain a magnet, and the other from the device and the removable cover may contain material characterized by magnetic attraction, and the magnetic field between the magnet and the material characterized by magnetic attraction is large enough to pull the removable module to the device in such a way as to ensure tight interaction between them. The interaction may include electrical contact between external elements for electrical contact located in the removable module and device. According to one example, a magnet is in the device. According to another example, the magnet is in a removable case.

Custom scripts include the scripts below.

According to one example, a telephone assembly is provided with a monoblock form factor and two screens containing a bistable display. The bistable display forms part of the removable cover of the telephone assembly. The advantage of a telephone unit with a candybar form factor and two screens is that one screen is always visible, no matter which side the device is placed on the table. By displaying the incoming message on both screens, they ensure that incoming messages are always visible when the device is on the table. The first screen of the display can use electro-wetting technology. According to another example, electric wetting technology, for example, Liquavista technology, may be used in the second display screen.

The appearance of the device node may be associated with a context, for example, associated with a location, for example, a location determined using a global positioning system (GPS) receiver, or related to weather, or related to temperature, or related to the time of day. The context-related (e.g., position-related) appearance of the device may include location-based advertising. The context-related (e.g., position-related) appearance of the device may contain location-based search results.

Alerting and configuration are important tasks in mobile computing environments. For notification, the use of sound, vibration or display devices based on LCD / AMOSID (liquid crystal display / active matrix on organic LEDs) is known. All of these methods provide alerts for a limited period of time, and cannot work continuously due to high energy consumption. There are cases with segmented bistable displays used for alerts, but they do not provide sufficient flexibility when working with informational messages and / or options.

There are many ways to configure the device node, and images and themes for the user interface (UI) on the main screen, sounds and other accessories, for example, various phone cases, can be used to change the appearance of the device node. The appearance of the device node can be changed by changing what is displayed on the bistable screen in order to set, for example, the appearance of various phone cases. For example, the screen saver of a device node can be changed. The screen saver of the device node can be one or more of wallpapers, photos, video clips, user-customizable content.

According to one example, a bistable display with an active matrix and high resolution is provided on the rear panel of the device assembly. The bistable display forms part of the removable cover of the device assembly. This improvement provides the following advantages over covers known from the prior art:

- phone setup - the user is able to provide the display of any circuit, image or application interface in order to distinguish his phone from other phones;

- Alerts - any application or service is able to display an alert on the rear screen; moreover, the time for displaying an alert is unlimited, since a bistable display is used;

- Alerts - any application or service is able to display an alert on the front screen; moreover, an alert, such as a message, can be displayed on the front screen and on the rear screen;

- the information remains on the screen, even if the phone itself is off; moreover, this is important even for manufacturing - the manufacturer can place all the necessary information directly on the bistable screen, for example, serial number, certification logos, country of origin, etc.

One example is shown in FIG. 1. In FIG. 1 shows a front surface and a rear surface of an exemplary device assembly. The device node is presented in the off state. In the off state, the front surface is not lit and is dark. However, when turned off, the bistable display on the back surface continues to display content that may be seen as a result of external lighting, such as ambient lighting. According to the example of FIG. 1, the front surface comprises an AMOSID based display, and the rear surface comprises a bistable electronic ink based display.

Interferometric modulation technology, such as Qualcomm Mirasol technology, can be used in a bistable display.

A device assembly comprising a removable cover may comprise two backlight modules, each of which may illuminate a display located on the main surface of a device assembly containing a removable cover. Each backlight module can illuminate a corresponding display on the corresponding main surface of the assembly of the device containing the removable cover. Two backlight modules can be located between the two displays that make up the device assembly containing the removable cover, each display located on the main surface of the device assembly (containing the removable cover), different from the surface on which the other display is located. The removable cover may include a backlight module for lighting the display of the removable cover.

A device assembly comprising a removable cover may comprise flat (i.e., non-curved) front and rear major surfaces. A device assembly comprising a removable cover may comprise one main surface that is curved, the other main surface being flat (i.e., non-curved).

A display device assembly with a curved monoblock form factor (for example, a telephone) containing a removable cover

A display device unit with a monoblock form factor (for example, a telephone) containing a removable cover can be characterized by a unique and organic shape, which is essential for quick individualization of products in a saturated market. Examples are shown in FIG. 3 and FIG. 4. A monoblock display device assembly with a removable cover may have a concave front surface and a convex rear surface. The amount of bending of the surfaces may be the same or similar. The concave front surface may correspond to the path of the finger when turning the user's wrist. As a result, the device will be very pleasant to use. The presence of a curved surface as a speaker system based on a vibrating loudspeaker with a distributed principle of operation (DML) is also preferable, because if the front display with the exciters of the speaker system is alternatively characterized by a flat surface, the system will sound unpleasant if you put the specified flat surface face down to the surface of the table. Bending the surface prevents this. Preferred bending of the front and rear surfaces is cylindrical, but spherical or aspherical bending is also possible. The convex rear surface may include a bistable display. Since the front surface is pointing down in the normal resting position, the rear screen with a bistable display is usually visible when the all-in-one display device is in the resting position. The indicated resting position is mechanically stable. If the monoblock display device assembly containing the removable cover is located with the rear surface down (i.e., the convex surface down), then the monoblock display device assembly containing the removable cover may rotate, which is unstable. Therefore, the user is most likely to position the monoblock display device assembly containing the removable cover with the front surface (i.e., the concave surface) down, with the bistable screen in this position.

If the monoblock display device assembly with the removable cover is in the pocket, the front surface (concave surface) can be turned inward, as this better corresponds to the bend of the leg. This may be a better configuration (compared with the front surface up) for the antenna to function.

In the manufacture of a curved shape may be covered with glass.

DML-based loudspeaker of a display device with a candybar form factor (for example, a telephone)

It is difficult to get good sound quality if you do not have a large speaker with a large and repulsive hole for the speaker. According to one example in this document, we use NXT plc Distributed Function Loudspeaker (DML) technology to vibrate the entire screen of a monoblock display device (such as a telephone) - the entire surface of the screen acts as a speaker. The speaker holes can be completely removed. Two small drives / exciters under the glass can be used to cause the screen to vibrate. Up to this point, DML technology has not been used to cause vibration of the screen surface in a mobile phone or a display device with a candybar form factor. A tactile regulator can also be provided through drives - a new use of DML pathogens.

The acoustic properties of the device can be characterized by the following:

Built-in sound recording and reproducing equipment: 128-voice polyphony,

QconcertPlus, Dolby 5.1 Surround,

noise reduction and echo.

Additional ANC (Audience).

Two microphones.

Sound produced using the display screen using NXT technology (without speakers).

Deep stereo sound from Surface Sound technology.

Lack of standard speakers.

Adaptive noise reduction.

The cover of a display device with a monoblock form factor and the materials of a removable cover can be characterized by the following:

Case: monoblock.

Materials: Plastic or Texin ™.

A flip phone assembly (for example, in the form of shell flaps) containing a removable cover can be created, and in addition to the main display, which is hidden when the phone is in a closed configuration, two bistable displays, one on each main surface of the phone when the device is in a closed configuration. One bistable display forms part of a removable cover. This ensures that even when the device is in a closed configuration, received messages can be displayed on both bistable screens so that the received messages are visible to the user even when the phone is in a closed configuration, regardless of which of the main surfaces is facing up. when the phone is lying on a surface such as a table surface.

It should be understood that the above arrangements only illustrate the application of the principles of the present invention. Various modifications and alternative arrangements may be devised without departing from the spirit and scope of the present invention.

It is possible to create a device with two displays, with a conventional display screen located on one side of the device, and a second display screen, such as, for example, electronic paper based display (EPD), located on the opposite side of the device. A second display screen can be used to provide full-screen display of content while providing low power consumption. The second display screen can also provide basic display functionality when the device is not in use, and can additionally display some additional content with little energy consumption. The limited availability of dual-display devices currently makes a solution for standard smart phones desirable. At least some of the benefits provided by a dual-display device may be available in the context of standard smart phones (smart phones) or smart devices (smart devices) through this set of examples.

In the context of this description, the smart device is a portable electronic device containing at least one screen, and also configured to receive alerts through a network connection. For example, the smart device may be a tablet computer or a mobile phone, which may be further equipped with one or more touch sensors. The set of examples presented below, although it will be understood by those skilled in the art that it can be adapted to various contexts, is particularly suitable in the context of smart devices such as a “candy bar” (monoblock).

This set of examples relates to a smart cover for a device (also referred to herein as a cover or removable cover), which can be attached to a smart device to provide an additional display. After attaching to the smart device, the smart cover for the device is rotatable relative to the device. In the closed position, the secondary display is located on top of the main display of the smart device and can thus protect the main display. In the open position, the main display of the smart device is available. The secondary display is typically an electronic paper (EPD) display, which provides an exemplary advantage of consuming less energy than other display devices such as a liquid crystal display (LCD) or an active matrix organic light emitting diode (AMOSID) display . The cover of the smart device may further comprise one or more special touch sensors. The smart device cover provides a data transfer interface in order to obtain information for presenting one or more images on an additional display. The data transfer interface can be unidirectional (for example, from a smart device to a cover) or bi-directional (for example, provides data transfer from a cover to a smart device). For example, the data interface may receive a fully rendered image for display on an additional display. The data interface may also receive partial information necessary for rendering the image on an additional display. For example, partial information may include instructions for displaying an image previously stored in the cover memory of a smart device in conjunction with other visual and textual information.

The cover of a smart device may provide some advantages, which, depending on an embodiment, may include at least some of the expected benefits of an additional EPD display with respect to a standard smart device. An EPD-based display can provide lower power consumption compared to the main display of a smart device, and an EPD-based display can also provide a better user experience in bright conditions than the main display of a display device. Other possible advantages of a smart device cover may include the standard use of a smart device when the cover of a smart device is removed, as well as the usual advantages of protecting a smart device and providing a smart device appearance.

Let us now consider the drawings, in FIG. 7A, FIG. 7B and FIG. 7C (also referred to as FIG. 7) presents an exemplary cover 100 of a smart device in accordance with the present invention. According to the example of FIG. 7, a back cover assembly 1, a data transmission interface 2, a hinge mechanism 3, a front cover assembly 4, an additional display 5 and a smart device 6 are shown. The smart device cover 100 further comprises a mounting mechanism (not shown), a memory module (not shown ) and a processor module (not shown).

The back cover assembly 1 may be configured to replace the back cover of the smart device 6. The back cover assembly 1 may further comprise a battery interface device (not shown) that can be used to power the battery of the smart device 6. For example, the battery interface device may comprise a physical connecting device (not shown) compatible with the external physical connecting devices of the smart device or the internal connecting devices, available pnymi through the back cover. The battery interface device may also be based on non-contact charging technology and / or may also include an additional battery (not shown). The additional battery can only be used to compensate for the uneven supply of energy from the smart device 6.

The data transfer interface 2 allows the cover 100 of the smart device to receive data from the smart device 6, and according to some additional embodiments, it can allow the cover 100 of the smart device to send data to the smart device 6. The data transfer interface 2 can be a small radius wireless network interface actions based on technologies such as Near Field Communication (NFC) or Bluetooth®, or may also contain a physical connecting device (not shown). According to a further embodiment, the physical connecting device for the data transmission interface 2 and the physical connecting device of the back cover assembly 1 can be combined (i.e., a single physical connecting device for both purposes). According to the example of FIG. 7, the data transmission interface 2 is provided located on the back cover assembly 1. Those skilled in the art will understand that the data transmission interface 2 can be located anywhere on the cover 100 of the smart device, depending, for example, on the type of interface used, as well as the size of the hardware components, optimization of wiring, etc.

An exemplary articulated mechanism 3 is provided as a continuous strip of flexible material located between the back cover assembly 1 and the front cover assembly 4. Those skilled in the art will understand that other types of articulated mechanism can be used without affecting the ideas of the present invention. The hinge mechanism 3 may further be configured to determine the relative position of the front cover assembly 4 and the back cover assembly 1 of the smart device cover 100 (for example, configured to make approximate measurements of angles, indicate a closed position, indicate an open position, determine a current closed position, current open position, etc.). The relative position can be used by the cover 100 of the smart device itself (for example, to influence what is displayed on the additional display 5) and can be additionally transferred to the data transfer interface 2 for transmission to the smart device 6.

The front cover assembly 4 is also presented as comprising an additional display 5. The inner surface (i.e., directed towards the smart device 6) of the front cover assembly 4 may be a woven material surface to prevent damage to the display of the smart device 6. According to an example presented in FIG. 7, the outer surface of the front cover assembly 4 includes an additional display 5. As indicated above, the additional display 5 may be based on EPD technology. According to a special embodiment, the additional display 5 may comprise one or more touch sensors, and the inner surface may also transmit, in a closed position, the touch schemes received from the additional display 5 to the corresponding signals suitable for smart device 6.
