The Canon LC-1 uses a large calculator chip 
soldered like a surface mounted device. 
The yellow LC-display is mounted behind
the black plastic hood. Exploring the copper
shielding foil reveals a DC/DC converter.

The later TI-1750 uses a similar housing
soldered from the backside of the
printed circuit board. The LC-display
is connected with 30 small springs.
