Ask Slashdot: Where Are the E-Ink Dashboards?

Posted by timothy on from the it's-called-chalkboard-learn-it dept.

fsck! writes "My office recently installed a pair of huge plasma TVs to display some metrics and graphs. They only update every 15 minutes or so, and I couldn't help but wonder, why can't this be E-Ink? I searched all over the place but couldn't find anything bigger than 9.5" (Amazon's Kindle DX). I want a >30" E-Ink picture frame with USB or WiFi. Can the Slashdot community find anything greener than these energy sucking plasma TVs that seem to be everywhere?"

    Plasmas can easily be replaced by LED LCD TVs that use a lot less energy.

    LCD and plasma for several years use similar amount of power...

    "Our friends at HD Guru did some analysis to determine if there is the real difference between “energy efficient” LED models, and “power hungry” plasmas. According to HD Guru, the LG 47-inch 47LW6500 LED LCD will have an EnergyGuide yearly estimated cost of $13. While the LG 42-inch 42PT350 plasma will have an estimated cost of $21.

    That's not much. And, as HD Guru points out, given the vast price discrepancy between the average plasma and the average LED LCD (over $500, in this example), it is highly unlikely you would ever see a return on your investment, power consumption-wise (62.5 years, between these two).
