1. What are the benefits of SiPix electronic paper technology?
SiPix electronic paper provides many attractive features. It is bistable, meaning that the image is maintained without loss to image quality when the power is removed. Given that power is only consumed when changing the display, SiPix e-paper is an ideal choice for systems with limited power budgets or battery size constraints.

Other benefits include environmental durability along with paper-like readability, flexibility and portability. We offer several monochrome and area color solutions with grayscale capabilities. No color filters are needed, preserving high reflectance.

2. Where may SiPix e-Paper be used?
SiPix e-Paper is particularly beneficial to applications which require low power consumption, flexibility, and excellent readability. Both segmented and active matrix modules may be customized to meet clients applications. No glass is used, enabling environmentally robust displays.

Commercial applications include pricing labels, indicators, logos and icons.

Consumer applications include smart cards, USB flash drive displays, fashion apparel, clocks, dynamic games, and giftware.

3. Why choose SiPix?
With SiPix electronic paper, designers may now choose from multiple saturated color combinations for both segmented and matrix displays. Our established manufacturing lines will give you economy and scale. We customize modules to shape and this modules highly resistant to abuse and moisture. We also offer display module services to resolve your design challenges to get you to the market quickly.

4. Do you offer evaluation kits?
We offer standard evaluation kits which include an EPD module, a controller module, a power supply, and cables. A user manual and specifications are included with each kit.

Users will benefit by avoiding PCB design for evaluation and will quickly be able to evaluate the optical performance and bistable nature of SiPix EPD modules. Please contact us for more information.

5. What is an Electrophoretic Display (EPD)?
An Electrophoretic Display (EPD) is a reflective display that uses electrophoresis to switch pixels or segments on and off. Electrophoresis is the motion of charged particles suspended in a liquid in response to an electric field. If the white particles migrate to the visible surface, the display exhibits the color white. On the other hand, the display reflects its alternate display color; for SiPix monochromatic displays this color is black, red, green, blue or gold.

6. When was electrophoretic display technology first created?
Electrophoretic display technology has existed for over 35 years and was first produced at Matsushita in 1969.

7. What is bistability?
Bistability literally indicates that without power a Microcup® may exist in either of two steady states, exhibiting either white or its contrasting color. In simple terms, the display has memory with ultra-low power consumption. Power may be removed from the display and the image content and quality, e.g., contrast, reflectance, and viewing angle, are maintained. SiPix Microcups® are actually "multistable" because grayscale tones are also retained when power has been disconnected. Only a small amount of power is required to change the content of the Microcup® electronic paper display.

8. Can you produce color?
We currently produce monochrome and area color solutions and have a roadmap to full color displays. Our monochrome colors are black, red, green, blue, and gold contrasted by white. Multiple regions of black, red, green and gold, contrasted in each region by white, may be combined to produce custom area color displays. Bistable grayscale color is produced by modulating the signal when driving the display.

9. How many voltages rails are needed to drive a display?
Only one voltage rail is needed. By principal, independent driver channels from the voltage rail create an electrical potential in reference to the transparent common electrode toward the front of the e-paper. This electric field drives charged white particles within the SiPix Microcups® to generate the display image.

10. Does SiPix make custom display modules?
We and our partners provide custom display module services to enable you to quickly bring your product to market. Please contact us with your requirements and application needs.

11. May you have holes or cutout the center of the display?
Yes, SiPix e-paper may be custom shaped to include holes and cutouts.

12. Is SiPix e-Paper waterproof?
SiPix e-paper is made of hydrophobic components and is therefore highly water resistant. Supporting electronics will likely need to be protected from humid environments.

13. What is the display thickness including the backplane?
Without a backplane, the thickness of SiPix e-paper modules is 150 μm. The backplane height may add an additional 100-700 μm, which varies by the type of materials used and the number of conductive layers. The thickness may be reduced considerably by using a metal foil, e.g., aluminum, or flexible organic substrate, e.g., polyimide.

14. Is your material plastic or glass based?
Microcup® e-Paper is a plastic-based material on flexible PET.

15. What lighting solutions do you recommend?
Our products are reflective by nature and are readable in sunlight, indoor and non-uniform light. In dimly-lit conditions, side or front lighting may be necessary.

16. What is the finest pixel size achievable?
The resolution is dependent on the pitch of the backplane. Also, no registration is required; where backplane electrodes cross Microcup® boundaries, the particles within the Microcups® will proportionately distribute corresponding to those backplane electrodes, enabling high edge resolution.

17. Can you drive icon shaped images?
Yes, unique shapes may be defined by the backplane to drive icon-shaped images.

18. Do you supply driver ICs?
Our partners offer driver ICs for EPD module development. Datasheets are available upon request.

19. Are COF, COB, or COG interconnect applications supported?
Yes, Chip-on-Flex (COF), Chip-on-Board (COB), Chip-on-Glass, Tape Automated Bonding (TAB) and other interconnect applications are supported with our module manufacturing processes.

20. How does your business engage with others?
SiPix offers customized electrophoretic modules in multiple colors and voltages. We seek partnerships with material & component providers, backplane & EPD module manufacturers, and distributors. Please contact us for more information.
