What is the LCD display intended for and what does it show and when does it display?

The display will indicate only for ‘low battery’ or during a smoke/carbon monoxide alert - showing the PPM - parts per million. No display alerting - green flashing light about every 40 sec during normal operation.

what is the lowest ppm detected?

Typically these type use time weighted average. Around 100ppm. Standard city air runs around 5ppm. OSHA personal types start alarm at 35ppm. Low levels help people with arthritis. Your gas stove shouldn’t go over 400ppm at light off. Must drop below 100ppm stable state. High efficiency furnaces produce around 30ppm. A human Fart can go 65 ppm. Exposure over 1000ppm can go bad in minutes. I’ve short term worked in 8000ppm! No happily. Some is always around.
