the technology for using this in low light is called a lamp!

in all seriousness, eink devices use something called front lights, which are embedded in the side of the tablet or device and project light from the edge of the screen. it works very well, even allowing red or amber light coloration which is great on the eyes. i have read that front lighting adds a little bit of thickness to a device, though my devices with the technology seem just as then as any of my regular lcd devices.
