Kindle Fire HDX screens reportedly suffering from purple haze issue

Kindle Fire HDX

The Amazon Kindle Fire HDX is a direct competitor to the 2013 Nexus 7, and it appears to have received a major setback just days after its official launch. According to new owners of the tablet, the 7 inch Kindle Fire HDX is suffering from a purple haze issue around the edges of the display. Issues like this are quite common in new devices and a user has been kind enough to upload a video briefly explaining this manufacturing defect. Best Buy is reportedly exchanging tablets suffering from this issue, but even exchanged units seem to be suffering from the same issue. So it seems like Amazon has to set it right from its manufacturing unit in China before thinking of exchanges, because the problem could be more widespread than we think.

The purple haze around the edges of the display is prominently visible on white backgrounds and is barely noticeable on darker backgrounds, so it shouldn’t scare off potential buyers in any way. The fact that Amazon is encouraging returns is also an acknowledgment of the issue and we can be assured that this glitch will be fixed.

    We want you to
    know…

    The Kindle Fire HDX 7″ has perfect color accuracy (100% sRGB),
    and we wanted to share more details around our display design decisions that
    helped us achieve this.

    You may notice a very narrow, faint blue tint
    around the edge of the device when looking at items with a white background,
    such as books or web pages. All displays have some level of light emission
    around the edges, and the light on the Kindle Fire HDX 7″ is blue due to the
    technology used to render perfect color accuracy. Most LCD displays use white
    LEDs, and then apply filters to extract the desired color. The result is
    oftentimes a compromise to tone and color accuracy, or-if attempting to address
    these compromises-an increase in battery consumption and, thus, device
    weight.

    We’ve taken a different approach. To achieve the perfect color
    accuracy on Kindle Fire HDX 7″ at the lowest possible battery consumption and
    device weight, we used blue, not white, LEDs. Blue LEDs allow for a much more
    accurate and rich representation of color and result in an up to 20% improvement
    in power efficiency.
