QUESTION: Dear ZZ

http://en.wikipedia.org/wiki/Seven-segment_display
http://www.maximintegrated.com/en/app-notes/index.mvp/id/1883
http://www.engineersgarage.com/electronic-components/7-segment-display

Is it possible to display content in different languages viz german, french, japanese, french, spanish, dutch, chinese etc using 7 segment led display other than english content in
products ?.

Products Examples : Weighing machine, Treadmill Machine, Steppers, Electronic meters etc

Will there be limitations in having a 7 segment led display for producing these products having 7 segment led display other than english content ?.

For example : Enter weight in Kg - This is english content
display in treadmill displayed in 7 segment LED Display.

Now can we have Treadmill products sold in different countries where the native language is spoken, for example In Japan Japanese, In China - Chinese etc having the equivalent of Enter weight in Kg in other languages viz Japanese, German, French, Italian etc displayed in 7 segment LED Display.

i.e. 7 segment Led display should be able to display multilingual characters other than english content.

Can there be limitations to 7 segment led display in displaying
different languages characters ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: Why are you even considering LED display devices?  Light emitting diodes are very 'old technology' for consumer products.  Most appliances, large and small, are using LCD display panels because they are much more easy to prepare the drivers to fashion the character maps for text, numbers, letters, symbols - anything graphic.  Whereas, the 7 segment LED design still needs logic driver but the range of display characters is highly limited.  And, there is no cost savings for using LED.  Further, for battery driven products the power consumption of an LCD panel is much less than LED devices.

The LCD panel can display any language and character if the software drivers are properly designed.  The segmented LED devices are extremely limited in what they can display.

The only advantage of LED is they are light emitting and can give a good visibility in daylight and in night conditions whereas LCD requires back lighting if dark nigh time viewing is needed.

Hoping this will help.

QUESTION: Dear ZZ

Thank you.

So as you mention using LCD read out panels with the right software drivers created for characters display, it is possible to design and develop different languages content in Weighing machine, Treadmill Machine, Steppers, Electronic meters etc ?.   

Requirements
------------

A push button on the above products viz Weighing machine, Treadmill Machine, Steppers, Electronic meters for selecting Language content.

If the user selects english, content will be displayed in english on
the LCD Readout panel.
If the user selects French, content will be displayed in french on
the LCD Readout panel.
If the user selects Japanese, content will be displayed in japanese on
the LCD Readout panel.
If the user selects German, content will be displayed in german on
the LCD Readout panel.
and so on ....

In this case the treadmill can be sold to any country as this can be classified having a universal design ?.

Can there be designing and manufacturing challenges for constructing this
multilingual electronic products ?.

Awaiting your reply,

Thanks & Regards,

Answer
Yes, all of your suggestions are possible and easily understood by software and engineer specialists who design and implement multi-language fonts into the readouts.

It is a no-brainer for those who design such apparatus.  The only challenge is cost of the panel, driver and software (purchase of language library, for example.)

Have a happy day.
