The completed module
This module comprised two designs, the LED display module and the main board it was mounted to. The LED module consists a printed circuit board and custom plastic molding. The custom molding includes a flame icon and a celsius symbol.
The icon is top right of the module
As with other Three-Five designs, the LED controller die was bonded directly to the custom LED PCB. Three-Five Systems had extensive experience with wire bonding, as all LED displays require wire bonding.
Sadly I cannot find a picture of the display in the final unit, so if anyone has one, please feel free to send me a copy.
