LinITX High Brightness in Cold weather

**hari-bhari** · 12-23-2008, 01:30 PM

on cold days (not necessarily sub freezing, but below like 40), the screen will display all white or bluish white for a few minutes until it warms up. the touchscreen still works fine during this period. i know people have posted about linitx screens not turning on in cold weather, so im not sure if this is the same issue. the screen is on, just the display image is all white til it warms up? could it be a loose connection or something?

Nope, that's cold weather, it happens very occasionally with my lilliput and they use the same panels in the basic ones.

damn well that kind of sucks. maybe ill switch to xenarc.

Xenarc will probably suffer as well.

the liquid crystals in the LCD (Liquid Crystal Display) tend to need warming up a bit.

Maybe it is just luck of the draw? No problems on my lilliput down to -25c so far.

-25... How does it not get full of condensation when it fires up, mine used to get water droplets in between the TS layers at anything below 3degrees C. Always made me worry that the inside was full of water too!

Easiest way to resolve was to have my aircon blast the back of the screen with dried warm air.

Try not to breathe in front of it. A little moisture on the front of the screen isn't going to hurt anything, especially since I have a screen protector. Just make sure it doesn't get inside the circuit board.

i didn't mean moisture on the screen, I meant in between the various films that cover the screen.

I have no idea how that would get in there. The only moisture I get is on the surface.

i opened up the screen and reseated all the cables and remounted all the boards, and now the issue seems to be solved. i guess the boards are prone to a loose contact problem, and when they heat up, the slight metal expansion brings the cable in contact with the board. just my hunch.
