Detailed Description
There is provided a detachable device case (eg. phone case) with a bi-stable or low (eg. very low) power consumption display on its back side. Figure 5 shows a bar form factor device housed inside its detachable case, to form a device assembly. The device (eg. phone) may be provided with a battery. The case may be provided with a battery. If there is a battery inside the device (eg. phone), a charged battery in the case can be used to charge the device battery. A user may detach a detachable case from a device when both the battery in the case and the battery in the device are discharged, in order to attach another detachable case with a well-charged battery, so as to charge the battery of the device, or to power the device. A user may possess several detachable cases, so that the user can exchange detachable cases several times in order to charge the device battery each time, or to power the device, without requiring connection to a mains power source.
A connection (eg. a data connection) from the case to the device (eg. phone) can be implemented by wired connector or wirelessly eg. by Bluetooth. A wired connection between the device and its detachable case may be implemented via a connection between the device and its detachable case, such as via a port of the device, such as by a USB- compatible port of the device, or such as by a custom port of the device. A connection between the device and its detachable case may be implemented via a connection between the device and its detachable case, such as via a port of the device, such as by a custom port of the device. The connection may be wireless. The detachable case may provide a port which is operable to provide the connectivity of the port of the device which is no longer available for use when the device is in connection with its detachable case. Such connectivity may be wired connectivity or wireless connectivity.
In an example, the device assembly comprises the device and a detachable case for the device. The device may include external electrical contact elements.

Context related (eg. position- related) device appearance may include location-based advertising. Context related (eg. position-related) device appearance may include results of a location-based search.
Notification and customization are important tasks in mobile computing. For notification it is known to use sound, vibration or LCD/AMOLED (liquid crystal display/ Active-matrix organic light-emitting diode) displays. All those ways provide notification for a limited time and cannot work in always-on mode due to high power consumption. There are cases with segmented bi-stable displays used for notifications, but they don't give right flexibility with notification messages or/and options.
There are many ways for customization of the device assembly - pictures and themes for user interface (UI) on main screen, sounds and different accessories like different phone cases can be used to change the look of the device assembly. The look of the device assembly can be changed by changing what is displayed on the bi-stable screen, such as to give the appearance of a different phone case for example. For example, a device assembly skin can be changed. A device assembly skin may be one. or more of wallpaper, photos, movies, user-customized content.
In an example, there is provided a bi-stable active matrix and high-resolution display on the back panel of the device assembly. The bi-stable display forms part of a detachable case of the device assembly. This improvement gives the following advantages in relation to prior art cases:
• Phone customization - user is able to display any pattern, picture or application interface to differentiate their phone from others
• Notifications - any application or service is able to display the notification on the back screen. Notification time is not limited, because a bi-stable display is used.
• Notifications - any application or service is able to display the notification on the front screen. The notification such as a message may be provided on the front screen and on the back screen. • The information remains on the screen even when the phone itself is switched off. This is important even for manufacturing - a manufacturer can place all needed information directly on the bi-stable screen: eg. serial number, certification logos, country of origin and so on.
An example is shown in Figure 1. Figure 1 shows the front face and back face of an example device assembly in the same Figure. The device assembly is shown in the off state. In the off state, the front face is not illuminated: it is shown as dark.

Curved bar form factor display device assembly (eg. phone) including detachable casing
The bar form factor display device assembly (eg. a phone) including its detachable casing may have a unique and organic shape - essential for rapid product differentiation in a crowded space. Examples are shown in Figures 3 and 4. The bar form factor display device assembly including its detachable casing may have a concave front face and a convex rear face. The magnitude of the curvature of the faces may be the same or similar. The concave front may match the path of a finger as the user's wrist rotates. Hence it's very natural to use. Having a curved surface as the vibrating distributed mode loudspeaker (DML) speaker is also better since if the front display with the speaker exciters was instead a flat surface, then it would sound unpleasant if that flat surface is placed down against a tabletop. Curving the surface prevents this happening. Preferred curvature of front and back is cylindrical, but spherical or aspherical are possible. The convex back can have a bistable display. Since the normal resting position is front face down, the back screen with bi-stable display is normally displayed when the bar form factor display device is in the resting position. This resting position is mechanically stable. If bar form factor display device assembly including its detachable casing is placed back down (ie convex face down), the bar form factor display device assembly including its detachable casing could spin, which is unstable. Hence a user will likely place the bar form factor display device assembly including its detachable casing front face (i.e. concave face) down, with the bi-stable screen showing.
If the bar form factor display device assembly including its detachable casing is in a pocket, the front face (concave face) can face inwards, since this better matches leg curvature. This can be the better configuration (as opposed to front face up) for antenna reception.
In manufacturing, the curved shape may be laminated to glass.
DML bar form factor display device assembly (eg. phone) speaker
It's hard to get good quality audio performance, unless you have a large speaker with a large and ugly speaker hole. In one example, we use NXT pic distributed mode loudspeaker (DML) technology here to vibrate the entire bar form factor display device (eg. phone) screen - the whole screen surface acts as the speaker. The speaker hole can be fully eliminated. One can use two small drivers/exciters under the glass to make the screen vibrate. DML has never been used before to drive a screen surface in a mobile phone or a bar form factor display device. Haptic feedback can be provided by the drivers too - a new use for the DML exciters.
Device audio properties may be characterized by:
On-board Audio: 128-Voice Polyphony,
QconcertPlus, Dolby 5.1 Surround,
Echo and Noise Cancellation.
Additional ANC (Audience).
2 Microphones.
NXT display surface sound (No speakers)
Deep stereo Surface Sound
No conventional speakers
Adaptive Noise Cancellation
The bar form factor display device's case and the detachable case materials may be characterized by:
Case: Single block

A hinged (eg. clam shell) phone assembly including its detachable casing may be provided which includes, in addition to a main display which is concealed when the phone is in a closed configuration, two bi-stable displays, one on each major face of the phone when the device is in a closed configuration. One bi-stable display forms part of the detachable casing. This ensures that even when the device is in a closed configuration, received messages may be displayed on both bistable screens so that the received messages are visible to a user even when the phone is in the closed configuration, irrespective of which major face is facing upwards when the device is lying on a surface such as a table surface.
