My comments on this technology

If you have ever tried to use your laptop, mobile phone or digital camera outside on a bright sunny day, you will have found it very difficult to read the device’s screen in that bright sunlight. Some users may have fashioned up loupes or shades to force the sun away from the screen and others may have preferred to work in shady areas like under a tree or in a shadow.

Pixel Qi have designed a colour display which uses a combination of LCD and e-paper technology to avoid this washout problem. It has the advantage of the always-backlit standard colour LCD display but uses the e-paper technology to enable reflective viewing in brighter lighting environments. This has also allowed for the backlight to be used only as needed, thus saving power and allowing for a longer operating time when on battery power.

Some people may think that these advanced displays won’t work well with video or games but they have the same refresh rate as the current-generation standard LCD display thus will work properly with these applications.

At the moment, the only screen size that is being built with this technology is the 10.1” widescreen which will be pitched at e-book readers, netbooks, subnotebooks, tablet devices and high-end large-screen electronic picture frames. This is mainly because they are supplying this technology to the low-power laptops that are part of the “One Laptop Per Child” project. They are yet to make smaller and larger screens for the other display applications like standard laptops, regular electronic picture frames digital cameras or HDTVs.

What I am definitely pleased about with this technology is that there is a colour LCD display that is friendly to all lighting environments and can allow portable devices to run longer.
