Title: Response time of LCD char display at low temperature
Post by: lkz6659 on April 02, 2015, 07:33:04 PM
I emailed Newhaven Display last week with a question but I never got any reply back.

I would like to use a serial LCD character display at very low temperature.  The ones I saw operate down to -20C.  But it is my understanding that LCD response time is very very slow when they are cold, on the order of several seconds to change characters.

Does anybody know what is the LCD response time for one of these displays at -20C?  For example the NHD-0212WH-AYGH-JT.

I would like to update the display twice per second.  Would this be possible at -20C?

Thank you for any help.

Hello,

I'm sorry, unfortunately we can not give you an exact response time without physically testing the display under those conditions.

You are correct that the response time will drop in very cold temperatures, but by how much? You will need to conduct some testing  8)
