Black, white Nook to glow in the dark

NEW YORK – Barnes & Noble says it’s tackling one of the shortcomings of black-and-white e-readers, by creating a screen that can be read in the dark.

E-readers with black-and-white screens, made by Barnes & Noble, Amazon, Sony and others, are easily readable in bright light but don’t come with their own light sources.

The new “Nook Simple Touch with GlowLight” has a standard black-and-white screen, but an array of light-emitting diodes inside the frame spreads a glow over the page with the help of an invisible light-guiding layer.

Barnes & Noble says the model will be in stores early next month and cost $139.
