Ambient light enters through the display screen and through the first layer of liquid and hits the reflective electrodes. When the light hits that reflective electrode, it bounces back out to the viewer's eye, creating the perception of a bright, color-saturated imageor text or video .
A small electric charge powers the movement of these oil and pigment-dispersion liquids. The movement occurs between a bottom layer behind the reflective electrodes and a top layer in front of the reflective electrodes. When the pigmented substance is positioned in the "top" layer (sandwiched between the ambient light and reflective electrodes), it creates a reflected ray of colored light which combines with literally millions of ambient light rays to produce a full-color display.
(The closest competition with similar brightness is electrochromic technology, which does not switch quickly enough to create video images. And the closest competition that is really low power but can still "do" video is called "Mirasol" technology developed by Quallcomm. However, when trying to display a color like white, the "Mirasol" technology has about one-third the brightness level of the UC technology being announced today. "Mirasol," in fact, resembles greyed newsprint.)
THIS NEW TECHNOLOGY IS MANUFACTURABLE WITH CURRENT FACILITIES AND EQUIPMENT
Importantly, the new e-Display design published today is manufacturable with current facilities and technology.
Manufacturability using the same equipment as that used for current LCDs was essential since a new LCD plant costs around $2 billion.
WHEN WILL THIS TECHNOLOGY BE AVAILABLE TO CONSUMERS
According to Gamma Dynamics' Rudolph, this electrofluidics breakthrough will change the display technology used in a myriad of electronic devices. e-Readers like the Amazon Kindle will be able to display color and
