Smartphone with Multiple Display Units
Smartphone with Multip  
QUESTION: Dear Prof Cleggsan

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,
Prashant S Akerkar

ANSWER: Sir, I am a very weak expert on smartphones so please don't put too much weight on my opinion.  

The idea of two displays is a very good idea for some users.  But, on the other hand it goes against the idea of being 'small' in size.

Wishing you well with this idea.

QUESTION: Dear Prof Cleggsan

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
But isn't it getting more like a tablet?  A tablet can have the display divided for two or three sections.  And, isn't the size of the triple display smartphone getting too large?  And isn't the cost profile getting out of bounds?  And isn't its weight and agility getting too cumbersome?

And, finally, would you have the side display screens removable or permanently attached?

It is a clever idea but maybe not so practical.

Here is an idea supposedly being developed by Microsoft:

It is display on front and back of smartphone.

They are working on patent for this approach, so reported in news.
