It’s time of year I wish someone would invent a screen for a laptop or tablet that you can read in direct sunlight. I’ve been trying to figure this out for a while.
Brilliant Idea #315 might be the answer. It’s a bluetooth screen the size of a tablet that mirrors whatever is on your phone, tablet or laptop, but it’s the same technology as a kindle or e-book reader. I think it’s called electronic ink, but whatever it’s called, it displays on a white background and can be read in the most direct sunlight.
It means that your extended screen is only now monochrome, but solves the problem that it’s impossible to use these devices when it’s sunny.
