Barnes & Noble's 7-inch Nook Tablet is due for a refresh. Critics have praised the crispness and clarity of its VividView color touchscreen, but its 1024-by-600 resolution is last year's news. Indeed, the Nook Tablet's biggest challenge its distinguishing itself among a growing throng of competitors. CNET reported that B&N's next 7-inch slate, expected to arrive this fall, will feature "revolutionary screen technology." The usual anonymous sources have revealed few details, other than that the new Nook display was developed in-house by Barnes & Noble and a third party. Given the bookseller's recently announced partnership with Microsoft, might that third party be based in Redmond?
Perhaps B&N will debut a hybrid screen, one similar to Qualcom's mirasol, which combines the best features of LCD and e-ink technologies. A mirasol screen doesn't have a backlight, but rather uses microscopic mirrors to reflect ambient light, making the color display easy to read both indoors and out.
