We have a rowing machine at home, which has a small built-in computer thingy with a small LCD display, which unfortunately has got smashed.
Although I know sweet FA about electronics, I decided to dismantle the computer to see if the screen was a readily replacable standard item. Extracted the computer from the machine - it just comprises a circuit board about 1" x 2" screwed to a casing, and below the circuit board is the offending screen, about 1.5" x 3".
So I unscrew the PCB and lift it off, expecting there to be some form of wires connecting it to the LCD display. But no, there isn't - absolutely no evidence of any physical connection to the display whatsoever.
The display drops out of the casing and I can see it comprises 2 thin sheets of glass (the front one being smashed), with a silvery-white, non-conductive sheet covering the back. No markings of any description.
So...
First - how on earth does the display work? Induction from the PCB or something? Is what I'm seeing 'normal'?
Second - presumably these displays will typically be bespoke to whatever equipment they come from? Or not...? (you'll have gathered it's not possible to obtain one from the original manufacturer of the rowing machine).
