E-ink displays give e-readers epic battery life and are easy on the eyes, but they are hampered by slow refresh times and currently come only in black-and-white. That’s why future devices could feature Qualcomm’s new Mirasol display tech, which matches E-ink’s long battery life and readability with an LCD’s ability to show vibrant colour and video. Like E-ink, it reflects ambient light, dispensing with a power-draining and eyestraining backlight. The company says we should see it built into e-readers as soon as this year.
