As far as I can tell the display is 4 areas, but because of the limits of the touch chip they use, they are connected together into just 2 areas. I think the limit is probably because of a lack of IO on the microcontroller.
Honestly, I'm not sure about what could be causing the accidental triggering - but as far as I can tell the touch controller automatically calibrates, so if the capacitance around it changes suddenly it might trigger.

I think the actual controller is the Holtek BS83A02A - link to datasheet on https://www.espruino.com/Bangle.js+Technical#hardware
