Sipix uses the non-emissive technology for its reflective screens which is based on the ElectroPhoretic Display (EPD).
 

	Global functioning : Charged particles move in colour fluid. If the particle is charged, it moves towards outside and the colour is not visible more. If not, it moves inside and we can see its colour.  These EPD screens are manufactured by Philips on three different technologies: Direct Drives Passive Matrix Active Matrix
	Direct Drives Microcup EPD Structure :   This technology is used to make flexible screens which can only show coloured segments. Each segment is controlled by a driver. As you can imagine, this technology is not in advance sufficiently for our product because we need to show pictures and video.
	Passive Matrix Microcup® EPD   With the Passive Matrix technology, you can control lines and columns of the matrix to access each pixel directly. This technology is able to show text with a sufficient average resolution for re-reading but not for showing pictures or videos. For the moment, these screens are monochromatic.
	Active Matrix Microcup® EPD Active Matrix technology uses TFT technology and allows the control of each pixel directly. The resolution begins to be interesting but at that time, the screen stays monochromatic. The colour will soon arrive. So, we think we have to see regularly the progress of this technology, even if, for the moment, it is not very in advance.
	Design features of Sipix’s screen technology: Picture technology:     - Reflective screen technology     - Bistabled picture Posting:     - Large view angle     - Uniform picture     - High refresh rate     - High contrast     - Still monochromatic (colour will soon arrive)     - Low average resolution   Flexibility:     - Totally Roll to roll screen     - Possibility to choose the size of the screen   Portability :     - Ultra thin screen (the thinnest of its category)     - Ultra light   Durability     - Very tough, and perhaps unbreakable     - Very long lifespan   Consumption     - Low supply voltage
