Re: is that what ElReg sarcasm looks like
Far better for daylight is to have a genuinely reflective display such as e-ink rather than a transmissive (light emitting) display such as the usual OLED / LED displays. However reflective displays are not so useful in the dark and colour accuracy depends entirely on the light source you are lighting it with.
Wearable tech is the future, right? Or so I keep reading. And if the industry analysts say so, then they must be right!
So all you do is have a reflective display, and a head torch, which outputs the correct colour temperature. It would have a light sensor on it, and a built in Bluetooth earpiece. Perhaps a pluse sensor and a thingy that detects how long your hair has grown, and automatically books your next appointment at the barbers. This way the phone can be smaller, as it doesn't need a battery for it's backlight, and it won't at all look odd wearing a giant torch on your head.
Remember you heard it here first. Who'll fund my Kickstarter campaign?
Question to the Aussies: What's this "sun" thing you keep talking about?
