    As we all know, current display technologies are based on Red Green Blue (RGB) sub-pixel architecture, which helps create full color image. Now there's another way. This method is nothing new (in fact, it can be found in some DLP sets) but, it goes to show how you can improve the image, and save energy at the same time (on flat panels) by just adding another sub-pixel (in this case, white).

    Here's an example:


    By applying this method to current display technologies; you can create an image that is twice as bright with half the power. I'm sure handheld junkies will love this technology.

    You can find more info by clicking the links below:

    While I am on the subject of display technologies, I stumbled upon a new overdrive technology by CMO who claim it reduces/eliminates motion blur completely on LCD displays without the annoying flicker or the ‘artificial look' that comes with 100/120Hz processing.

    The new overdrive works by slightly dimming the image just before displaying the next. For example, standard Active-Matrix LCDs ‘hold' each frame for 16.6ms at 60Hz before display the next, which causes retinal persistence. In other words, the image becomes temporarily ‘burned' in the eye's retina. If it's not removed, it will cause blur like effect during motion (when the ghostly image of the previous frame overlaps with the new frame). So by slightly dimming the brightness for the last few milliseconds, the ‘ghostly' image can be removed or reduced from the eye's retina.

    This idea was actually conceived from the old CRT technology. It's surprising to see how advanced CRT technology really was (and still is). Below the front glass of the CRT lies the phosphor coating. When it's hit by the electron beam, it becomes ‘excited' and emits light. The phosphor will continue to emit light for about 1-1.6 milliseconds then begins to fade, which causes slight flicker but at the same time, it helps to remove the previous image from the eye's retina. Now you know why there's no motion blur on your old boob-tubes LOL.

    Make sure to lookout for a LCD displays with this technology in the near future.
