E Ink screens deservedly earned its place in the market. However, the use of this screen type is not limited to electronic books. Onyx International company, released a prototype of smartphone running Android with a screen diagonal E Ink supposedly 4.3 inches.
Advantages of this approach are the same as in the case with e-books: the extremely low power consumption, respectively, significantly longer battery life of the device, as well as excellent screen readability in sunlight. At night, the same problem should not occur when using internal illumination.
Such a device can operate up to a week without charging. Of course, this figure also depends on the hardware platform, and directly from the battery capacity. In this case, the processor ARM Cortex-A5 (maybe Qualcomm MSM7227A). Weight of the prototype is impressive - 70 g
Of course, at this stage of E Ink screen technology, such devices will either remain prototypes or produced extremely in limited edition. However, over time, when the refresh rate will be increased to normal values and, finally, begin full production of color screens , you can expect the popularity of such displays.
