Hello

Thank you for the idea : bigger screen , no button . However I've  many info to display . I could also do a kind of roll out 

Do you have the schematic for HB LCD ? Not existing anymore on his website 

It's the same as this

but without the DS2890

There are 3 pins left on DS2408 in mine I connected 1 pin to backlight through a transistor 
another to a button and third to additional LED. 

But I think that the better approach is to use Maxim design with 8 outputs for LCD and add another DS2408 for input buttons. DS2408 has latching so you don't have to push the button while reading it just remembers the pushbutton. I don't know if it's possible to mix it with LCD output on one DS2408
