Amazon applies for dual-display device patent, where e-ink and LCD play nice together

Been holding out on that Kindle Fire purchase because you just can't wean yourself off the eye-friendly e-ink? Well, this patent application from the folk at Amazon suggests this is something they're not unaware of. The patent outlines a device incorporating two or more displays, one being static in nature (a-la e-ink) and the other more suitable for video (that'd be LCD or OLED etc). If you're thinking this sounds like a fast route to flat-battery town, the patent argues to the contrary. The static display would save power by offloading the workload from the LCD, when its slow moving nature was more suitable to the content. Will we see something like this popping up next week? One can but dream.
