Simple STM8 library was written to drive this IGT1-203 display panel. It uses one ADC channel, TIM4 scan timer and embedded IDWG watchdog for better stability.

IGT1-203 Self Scan bar graph display
Another bunch arrived on my workbench, my recent eBay purchase, IGT1-203 plasma bar graph display. This is single channel self scan plasma display with a working principle similar to PBG12201 panel indicator (Love that glow in the dark!). IGT1-203 has 5 scan cathodes, one reset segment/cathode, one anode for linear control, and two keep-alive pins.

Schematic is pretty simple:
