The reflection principle

The reflection principle is used along with the transflection

principle for LC displays which have been manufactured in

Ad-TFT technology.

Ambient light is reflected by the microreflective electrodes. This

reflected light is used on the screen surface by controlling the

RGB transistors using a "colour matrix". The corresponding

image is displayed on the screen surface, according to RGB

transistor control.
