Full color electrophoretic displays utilizing colored particles, no color filter array, and a single TFT array backplane have been demonstrated for the first time. A full color gamut including all eight primary colors has been achieved with a single layer of electrophoretic fluid addressed with voltages compatible with commercially demonstrated TFT backplanes. Displays have been made with incorporation of the electrophoretic fluid into both Microcup® and microcapsule structures.

Full color displays rendering any color and white at any pixel location have previously been demonstrated using E Ink's ACeP technology. The update time has now been improved to less than 1 second for color, and a high‐speed black and white mode has been developed. Even faster color modes are available for animation and pen writing. The improvements are made possible by improved electrophoretic compositions and novel TFT backplane architecture.

Exposure to fluoroquinolone antibiotics is postulated as a risk factor for subsequent development of type 2 diabetes. It is hypothesized that fluoroquinolones induce an intracellular magnesium deficit that can lead to insulin resistance. A temporal correlation is reported between the rate of outpatient prescription of quinolones and the incidence of diabetes during the period 1980-2011 with a lag of approximately two years (R(2)=0.86, P<10(-9)). The increase in incidence of diabetes after 1990 and the recent decrease in the number of new cases are both reflected in the fluoroquinolone prescription rates. A geographical correlation is reported (adj. R(2)=0.7, P<0.0001) between rates of increase in prevalence of diabetes in each U.S. state and a model using only local rates of outpatient fluoroquinolone prescription, local rates of increase in the prevalence of obesity, and local rates of population growth as predictor variables. Prescription rates of non-quinolone antibiotics correlated less well with the local rates of increase in prevalence of diabetes. The data are consistent with fluoroquinolone exposure predisposing an individual to develop diabetes with a probability that strongly depends upon factors that also lead to an increase in obesity. According to the hypothesis, much of the increase in the incidence of type 2 diabetes in the U.S. from 1990 to the present can be attributed to fluoroquinolone exposure.

Flexible variable transmission films (VTFs) have been developed and demonstrated using charged, polarizable pigment particles. Unlike electrochromic VTF devices, these E Ink films have a neutral black color and are not current driven. And unlike conventional PDLCs, the films are truly bistable, requiring no power to maintain the transmission states. Applications include automotive sunroofs and windows as well as architectural skylights and windows where energy savings and improved lighting comfort can be realized.
