FAQ

 Q: Are your E-Paper Displays RoHS compliant?

A: All of Good Display E-Paper Displays are RoHS compliant.

 

Q: What is the difference between an Matrix display and an Segmented display?

A: 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.

 

Q: What is Good Display's minimum purchase quantity for Matrix displays?

A: You can purchase one unit matrix display for standard products, but you must have 100,000 unit and even more volume for custom products, 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.

 

Q: What is the pricing for Good Display Matrix displays?

A: 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.

 

Q: How large/small can Matrix e-ink displays be?

A: The size and shape of a Matrix e-ink 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.

 

Q: What voltage is required to drive a Matrix e-ink display?

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

 

Q: How much power does a Matrix e-ink display consume?

A: Matrix e-ink 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.

 

Q: Does Good Display have developer kits for Matrix products?

A: Yes there are developer kits available for Matrix products from Good Display. 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.

 

Q: Does Good Display have a color product or is it only monochrome?

A: Good Display does have a color product which was launched in November, 2010. A color 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.

 

Q: How long does it take to update an image on an Matrix e-ink display?

A: 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 notchanging do not require updating.

 

Q: Can an Matrix e-ink display support animation or video rates?

A: 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.

 

Q: Does Good Display provide or support flexible matrix displays?

A: The flexibility of an EPD display is controlled by the backplane. Good Display does support flexible backplanes, now we have 1.43" flexible matrix display.

 

Q: What is the thickness of an Matrix E-Paper display?

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

 

Q: What is the temperature range for Matrix E-Paper displays?

A: The operating temperature range for an Matrix display is from 0-50 °C, and the storage temperature range is from -20-70°C.

 

Q: What is waveform?

A: Waveform are predefined voltage impulse sequences used by display controller to manipulate ink.
The voltage sequence and temperature range are stored in a lookup Table(LUT) and is precisely paired to the display by production lots to enable precise placement of pigment to achieve accurate gray-level.

  

Q: Why does waveform need?

A: Because of every lots of E INK material has slightly different at ink characteristics which effects are temperature dependent.
So, waveform is a driving method which consider the factor of temperature, production lot, display size and waveform type to control the each lots of EPD performance at same range, and this is Good Display's responsibility to provide the suitable waveform to our customer.

 

Q: What are the types of waveform mode?

A: The waveform mode optional argument allows you to select the type of waveform update.

WF type

Updated time

Properties

INIT

4 sec

1

The INIT waveform flashes the display and drives the display to a white state. Used this waveform if the display is in an unknown state such as when the previous image is unknown due to reboot, or just test the host function.

MU/DU

260 ms

1

Direct update is only used when pixels are updating from any gray-level to either white to black such as handwriting or menu. Gray pixels will not be affected, MU/DU is about twice as fast as GC or GU.

GU

780 ms

2~4

Grayscale Update is a non-flashing waveform that can be used to update changing grayscale pixels.

GC4/8/16

600/780/980 ms

2~4

Grayscale Clear is a flashing waveform used to provide the accurate update performance. All pixels are updated or cleared.

 

Q: What is the normal product lifetime of Good Display's e-ink display?

A: For standard products, it is a minimum of 5 years or the times of refresh is 1,000,000. 
 

Q: Do Good Display E-Paper Displays have CE certification?

A: CE certification is typically given to end products. Since the E-Paper Display is a component, it does not carry CE certification.
