1. How do e-paper displays work and what are they made of?

Although you can’t see them with the naked eye, e-ink displays are composed of millions of tiny capsules. These capsules, about as wide as human hair, are filled with minuscule particles of different colors, most commonly white and black.
An electronic ink screen uses positive or negative electric fields to move these particles from the top or the bottom of the capsule. Usually, the white particles carry a positive charge and the black ones carry a negative charge. If the electric charge applied to one spot is negative, the black particles rise, changing the color of the display’s surface. Pretty amazing, right?

2. Can e-paper come in different colors?

Electronic paper can have more than two colors. As with grayscale e-ink displays, electronic ink displays with more than two colors are bi-stable and don’t consume power during standby. However, the more colors there are, the more complex the display refresh becomes. The content on the screen takes longer to update.
The time to refresh the image on color displays can take up to 30 seconds, which is 30 times longer than grayscale images take to update. This lengthy refresh time significantly increases the device’s overall power consumption, making color e-ink displays inappropriate for battery-powered applications that involve more than a simple standby image.
Still, research is advancing every day and E Ink experts are continually exploring ways to make color electronic paper displays more energy-efficient. Visionect is looking forward to the day when we can deliver quality, power efficiency, and color in one stylish package.

3. What temperature range can the e-paper displays be used?

The operational and storage temperature range that electronic papers thrive in is 32°F to 122°F (0°C to +50°C) — perfect if you need a weatherproof solution, wherever you are. Still, e-ink displays have proven robust in more extreme conditions from -5°F to 150°F  (-20°C to 65°C).
Whereas LED and LCD displays generate heat while in use, electronic paper displays do not. This characteristic is due to the ultra-low refresh rate of the displays, considering electronic paper requires no energy to keep an image on the screen. With such low power consumption, the energy-efficient displays remain significantly cooler in hot climates.

4. Are e-paper displays eco-friendly?

Yes, without a doubt!
Electronic paper displays are the most energy-efficient displays on the market. The wireless displays have ultra-low energy costs and run months on the amount of power it takes to brew a cup of coffee.
Every component of Visionect e-paper displays is hand-picked for unparalleled energy efficiency. From WiFi modules to microchips on the system board, all refined by a decade of research, the displays are as power-efficient as possible.
While all electronic paper displays have an impressive battery life, only the best are made from sustainable resources. Visionect displays are constructed of reusable and recyclable materials, minimizing their impact on the environment. Plus, our manufacturing process is structured to have a negligible impact on the local environment while our tree-planting initiative helps bring each device’s carbon footprint down to zero.

5. Why should I use e-ink technology instead of LCD/LED?

Over the past two decades, LCD displays have dropped in price, making them affordable solutions for many use cases. Affordable, yet not necessarily ideal. LCD screens are prone to glare and are difficult to read in direct sunlight. Also, the liquid crystal in these displays is susceptible to temperature-influenced performance issues.
Another roadblock with LCD devices is their power consumption. These displays need to be connected to a continuous power supply, limiting their versatility and complicating their installation
On the other side, E-paper displays operate without fail in nearly any climate, hot or cold. The paper-like screens resist glare and are easy to read in daylight. The best part is, e-paper displays are the most energy-efficient screens on the market. Each device can go months on a single charge or easily run off of solar power, making them virtually wireless and easy to install.

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.

    The operating temperature range for an Matrix DES display is from -20-60 °C, and the storage temperature range is from -25-70°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.
