Pixel Qi’s Transflective LCD kills e-Ink

It’s just one screen with multiple modes –  a bright full color LCD, reflective E-Ink black and white quality, and transflective LCD mode. That’s pretty damn amazing if you ask me.

The Pixel Qi screen while in eReader mode has a lot of pluses –  Black and white with 64 shades of grayscale.  It’s reflective so it works in sunshine.  It uses very little battery power in black and white mode.  The full-color mode of Pixel Qi screens is like an LCD screen.  It even does what no other e-Ink display can, plays videos and full color photos.  You get everything you get with a regular LCD screen, just the lower power and higher-resolution of an e-Ink display. Pixel Qi won’t reveal yet how many nits when running at full brightness, and although it won’t win any illumination awards, it’s plenty bright. How it handled motion was a bit harder to gauge, when turned, it immediately switched to the electrophoretic reflective mode—where backlighting is replaced by ambient light reflecting off the back of the screen. In that mode, it is just as crisp as the Kindle for reading text. You can watch video in this mode too, though it’s not exactly pretty (the point being you don’t have to wait forever for the screen to refresh when you turn a page). They wouldn’t speculate on how much battery life improves when you turn off the backlight, simply stating that it saves you 2 watts of power.

They’ll be able to produce different sizes, for different form factor devices, meaning we should see them in a lot of different things over the next year or so.

  1. Best video of Pixel Qi outside on sunlight in front of Vegas Hotel is found here:

    Now, where is a device we can buy today that has AA battery, so we don't need to throw out these portable devices in a couple of years when we can't find a battery anymore (with a sales life of 6 months for all these netbook and mobile devices, good luck finding a battery in a year or two).

    Looking as well for a device with ARM or new Intel Moorestown CPU (as both can have CPU shut off when reading or writing email, or when it is not needed at all), to save on battery where CPU shuts down like OLPC XO-1 did and we get more battery life than just the Pixel Qi screen itself does at one-fifth the battery use of normal screen.

  2. I want one!

    Seeing this, there's no way I'd buy a dedicated e-book device now. I'd rather wait til these screens are available in laptops or netbooks.
