#127587 - They get very slow! Responding to: ???'s previous message |
At -25c the LCD response time is measured in seconds, not milliseconds. The on time and the off time differ, so the display can show junk for significant periods when the output is changeing. A heater is a possibility, but it's hard to insulate an LCD, so you might need quite a lot of power.
If you don't want to use a VFD, check out OLEDs and PLEDs. |
