What is the difference between an E Ink Matrix display and an E Ink Segmented display?

The underlying ePaper technology is very similar but is tuned to the needs of the different applications of a Matrix display versus a Segmented display.

Matrix displays are intended for applications requiring the display of many different forms of text and images. These displays comprise of a large array of pixels. These individual pixels are controlled by a TFT array similar to what you will have a typical computer monitor or TV screen.

Segmented displays are intended for applications where the display requirements can be met using predefined segments that can be turned on or off. This is similar to what one would see in a typical calculator with a numeric or alphanumeric display.

Basically will the display be made up of an array of pixels or by a collection of predefined shapes.

Does E Ink sell complete display modules or just the display film (FPL)?

E Ink actually sells both for matrix applications. You can order a fully assembled display module with a TFT attached to it. Or you can order just the cut FPL part which you will have to laminate to some form of electrical backplane like a TFT to control the electronic ink.

What is E Ink's minimum purchase quantity for Matrix displays?

This varies based on the size and requirements of the display application and whether it is a custom or standard size display. It is best to discuss your requirements with a member of our sales team.

What is the pricing for E Ink Matrix displays?

Pricing for Matrix displays depends on volumes and whether the display is a custom or standard display. The main driver of pricing is the overall display size, whether the display is monochrome or color.

Can I use E Ink Matrix displays for academic research, educational projects, or personal use?

This will vary depending on the project and the research involved. E ink does engage in research projects and collaborative work through E Ink's internal research and development groups. These are usually projects that are aligned with our business goals.

How large/small can E Ink Matrix displays be?

The size and shape of an E Ink Matrix display is totally dictated by the size of the electrical backplane that the FPL is laminated to. Displays can be very small or very large. E Ink has standard display modules. Almost any size and shape can be made depending on the volumes.

What voltage is required to drive and E Ink Matrix display?

The drive for E Ink displays is typically 15 volts. An ecosystem of electronic components exists for design of complete epaper systems.

How much power does an E Ink Matrix display consume?

E Ink Matrix displays are bi-stable. This means that they only consume power while the display is being updated. No power is required to maintain an image after it has been updated. The power required to for the update process depends on the size of the display but is of the order of microwatts.

Does E Ink have developer kits for Matrix products?

Yes there are developer kits available for Matrix products from E Ink and from our partners. These kits are not available for general sale. They are available for customers who are evaluating a display for incorporating into an end product. The best way to access the kits is by contacting sales.

Does E Ink have a color product or is it only monochrome?

E Ink does have a color product called Triton™. Triton was launched in November, 2010. A Triton display is similar to the monochrome FPL, except that it has a color filter array over the FPL to generate color. This is similar to the RGB pattern that an LCD TV uses to generate color from a white light.

How long does it take to update an image on an E Ink Matrix display?

An E Ink display module supports numerous modes for updating the display. Different modes exist to support the different update requirements. Update times can be as short as 120 msec. for the entire display. Also to consider is that because E Ink screens are bi-stable, only the regions of the screen that are changing require updating. Any pixels that are not changing do not require updating.

Can an E Ink Matrix display support animation or video rates?

Using the faster update modes, E Ink screens can support animation quality video rates. A number of examples are available from customers that show examples of E Ink screens showing video.

Does E Ink provide or support flexible matrix displays?

The flexibility of an E Ink display is controlled by the backplane. E Ink does support flexible backplanes and customers are using E Ink FPL in flexible displays.

What is the thickness of an E Ink Matrix display?

Thicknesses range from 1mm to 1.2 mm. This includes the FPL, protective sheet and the glass TFT backplane.

What is the temperature range for E Ink Matrix displays?

The operating temperature range for an E Ink Matrix display is from 0-50 °C.
