Some of my fellow analysts have been bemoaning a lack of TV, tablet, and cell-phone innovations at CES 2014. Well, either I have lower standards than my colleagues or a keener eye because I saw quite a few things that surprised, delighted, and horrified me. Here are some of them.

Kindle Fire HDX 7 with QDEF (right) is tuned to give better color gamut and much better power consumption.

3M’s Quantum Dot Enhancement Film (QDEF) using quantum dots from partner Nanosys is now in a high-volume shipping product. 3M was coy about identifying the customer, but partner Nanosys (which supplies the quantum dots used by 3M) didn’t hesitate. QDEF is being used in Kindle Fire HDX 7.0 and 8.9 inch tablets. The 8.9-inch has a 2560×1600-pixel display withg 339 pixels per inch (ppi), and uses QDEF to increase the color gamut from 60% to 72% NTSC. This is a noticeable although not extreme improvement, but Amazon asked 3M and Nanosys to optimize the system to significantly improve battery life, even if that meant only a modest improvement in gamut. They did. Battery life is substantially improved.
