Smartphone with Multiple Display Units
Smartphone with Multip  
QUESTION: Dear ZZ

As attached in the figure,

The Smartphone / Cell Phone Device instead of one will have two display units for viewing simultaneously . Both or One display window can be activated / deactivated with push buttons on the device. The Second rectangle has a door which can be closed and opened on the main display and is overlapped.

The touchscreen / keypad model will be shared with both the display units. i.e. common keys, push buttons.

As a example,

On default first window a Game is played, while on the second window, user is checking his mail box.

Do you feel, if this design (Smartphone and Cell Phone) is constructed, can this be useful to the consumer ?.

If not, can you suggest some design changes which may be liked by the consumers ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: Seems like a splendid idea.  At least for those users who are adept with smartphones like video and gamers, developers, code writers and such.   Good idea.

The implementation may be expensive;  I am not sure what additional cpu support and software development may be necessary to be added but it is probably not trivial.

You would need to work closely with a smartphone manufacturer to license your idea.....

Hope this helps.

QUESTION: Dear ZZ

Thank you.

As attached in the figure,

Do you feel a triple display unit can also be manufactured ?.

Added one more display window on the left to make it a triple display unit. The Left , Main/Middle and Right window. All three windows can be activated / deactivated with push buttons. The Left and Right window will be overlapped on Main / Middle Window when closed.

Power switches for left and right window activation / deactivation provided on the main/middle window.

The smartphone, cellphone device will be folded when the consumer is travelling.

The touchscreen / keypad model will be shared with all the three display units. i.e. common keys, push buttons.

Awaiting your reply,

Thanks & Regards,

Answer
Technically it could be designed and manufactured. Don't know about cost but seems very expensive and may not be any more functional than 10" or 12" tablet.  Since size and weight are important to smartphone users your approach may be too big, too heavy, too awkward for voice communication.

But, on the other hand, new features might be envisioned that would make such a device uniquely important to certain users in the development or gaming community.

I suggest you consult with other experts on this device idea.
