Ow my eyes

It stopped raining this morning.

must be global warming then

More modern screens are deliberately polarised at 45 degrees to avoid this problem.

The result of my polarisation experimentations:

• PC, LCD screen : Marked 45 degree polarisation (to almost blackness)
• TV, LCD screen : Marked vertical or horizontal polarisation (to almost blackness)
• Galaxy S2 WiFi screen: Slight polarisation, mostly just changing colours a little

My S2's screen is polarised top-right to bottom left, so holding my spleebs 45 degrees left blacks it out almost completely. My laptop LCD is completely black at the same orientation, which means the laptop must have a narrower polarisation angle.

Coincidentally, a related effect can be used to create a 'private' LCD monitor, that only someone wearing appropriate glasses can see.

My ipod touch is at 45 degrees. My Galaxy S WiFi is a cheaper version of the S2 and the screen is probably a different technology to the posher S2 phone. It's a bit of a biatch to read in bright sunlight (not bright enough), but using polarising lenses seemed to improve clarity a smidgen even though its polarisation is small.
