Please see following important safety instructions:
1. The nominal voltage of DC input to the A/D board is 12V, The size of DC current depends on the TFT LCD panel, audio amplifier, etc. Please note that your AC/DC adapter's output plug need to match the DC input jack, the diameter of the jack is 5.5 mm.
2. Before connecting these input/output ports, Video port, it is strongly recommended that your turn off the A/D board and remove the DC 12V plug from the DC input jack.
3. Don’t put the A/D board into an airtight package. When it works, it will produce a certain heat.
4. When assembling it, please use a suitable force; don’t distort the PCB and other components.
Q: Do you have more information about Bluetooth-communication between Access Processor and ESL Tag? Which standard is used?
Q: Which frequencies?
Q: Do you have any documents that use in Europe is allowed?
A: We're applying for the CE approval, and will get the certification in September.
Q: Is communication between Access Processor and ESL Tag protected/save?
A: Yes, it is protected.
Q: How can we avoid unauthorized access to the system?
A: The communication is encrypted by AES(Advanced Encryption Standard)
Q: You told me, that lifetime of ESL Tag is between 5 and 10 years. Can you also tell me the max. number of refreshes? In my opinion this value is better to calculate.
A: Yes, this value is worked out by calculation, as 4 time refresh per day and waked up once very 20 seconds.
Standby current: 0.001mA
Waked up peck current:10mA
Refreshed peak current:20mA
The aboved values can be measured
A common CR2450 Electric quantity is 620mAh
So we can get the electric quantity for one hour
Standby electric quantity:0.001x1=0.001 mAh
Waked up electric quantity:3600/20x10x0.01/3600=0.005 mAh (as peak value)
Refreshed electric quantity:20x0.3x4/3600=0.0067 mAh (as peak value)
The shortest lifetime of ESL tag is 620/(0.001+0.005+0.0067)/24/365=5.573 years
In fact, most ESL tags can't reach 4 time refresh per day, so we said that lifetime of ESL Tag is between 5 and 10 years.
Q: Am I right, that POE is possible for Power supply of Access Processor?
A: Yes, you are right, our current Access processor just support POE power supply, our engineer considered this one.
Q: What is the difference between an epaper matrix display and an epaper 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 E Ink's minimum purchase quantity for custom Segmented displays?
A: Good Display has a minimum quantity per order requirement of 10,000 units.
Q: Does Good Display have standard Segmented displays?
A: Good Display has several standard parts available at good-display.com.
Q: What is the pricing for Good Display Segmented displays?
A: Good Display develops Segmented displays for its customers based upon the minimum quantity per order commitment of 10,000 units. Pricing is dependent upon volume, including a minimum quantity per order commitment of 10,000 units, overall display size, and the number of segments required for the display. Segmented epaper displays are generally more expensive than traditional TFT LCD and LED displays.
Q: What if volume is less than 10,000 units per order?
A: In some cases, Good Display standard epaper displays can be used for your design. They can be purchased at buyepaper.com
Q: Does Good Display develop prototype Segmented epaper displays?
A: For those customers who are investigating an Segmented epaper display application, we provide a prototype development program. Good Display works with customers to finalize the specifications for the desired display. Based on the specifications Good Displat will provide a quote for the prototype design. Upon completion of the specifications and quote acceptance, first working samples can typically be delivered in 5 weeks. At the completion of the prototype, per unit mass production pricing is finalized.
Q: Can I use Segmented epaper displays for academic research, educational projects, or personal use?
A: Yes, we recommend that you use one or more of our standard displays, which can be purchased directly at buyepaper.com.
Q: How large/small can Good Display Segmented epaper displays be?
A: The smallest Segmented display dimensions are approximately 6x6mm. The largest display is 600x400mm.
Q: What voltage is required to drive a Segmented epaper display?
A: Segmented epaper displays can be driven between 5 volts and 15 volts.
Q: How much power does an Segmented e-ink epaper display consume?
A: Segmented e-ink epaper displays are bi-stable; they do not consume power after an update. It takes of the order of microwatts to switch from one display state to another.
Q: What is the minimum number of segments that can be created with E-Ink epaper?
A: Segmented displays range from 1 to 200+ segments.
