I wouldn't have thought so, it sounds like you are refreshing the LCD too often, and seeing the resultant flicker - try updating the display less often.

No, little ones aren't polarized.

yeah..!!


That's true...

i refresh it very often...
i refresh it at the same time that a led flickers.. but when i turn of the backlite i don't see it flicker.. but maybe the light switcehs on and off..when i refreh..

Dont refresh the entire 2 row of LCD just to change a few characters.
Just go to that lcd address and change that character.

..situation

yeah ok..

but when i press a button i see other things

soow don't know if that would improve..the sityuation qua speed

etc.
