Maybe the screen could be blacked-out when no data is present to display. (so Kindle paper white tablets can be on for hours at a time and not have burn-in?)

Note that the screen cannot be powered on for a long time. When the screen is not refreshed, please set the screen to sleep mode or power off it. Otherwise, the screen will remain in a high voltage state for a long time, which will damage the e-Paper and cannot be repaired!

I strongly recommend testing a smaller one to get some hands on feel for how it operates, if you are considering any dynamic information display.

Fuses: Fuses help preserve components from overloading with excessive current. A fuse consists of connection body, support, contacts, and metal-fuse material such as zinc or copper.

Is the horribly slow refresh noticed mostly with complex graphic images, or does simple text have the same refresh behavior?

For E-paper displays that support partial refresh, please note that you cannot refresh them with the partial refresh mode all the time. After refreshing partially several times, you need to fully refresh EPD once. Otherwise, the display effect will be abnormal, which cannot be repaired!

It is a normal phenomenon that the three-color EPD will have a certain color difference in different batches. Hence, It is recommended to use the program to clear all the pictures on the EPD and store it facing up. Please clear the screen several times before powering on.

Batteries: Batteries convert chemical energy to electrical energy. The two different cells of a battery are anode (+) and cathode (-).

Relays: These electromechanical switches shut power on or off. A relay includes an electromagnet, an armature, a series of electrical contacts and a spring.

What are electronic components used for? Microcomputers are small computers used to control a multitude of devices, such as power tools, remote controls, medical equipment and office machines. Batteries convert chemical energy to electrical energy. The two different cells of a battery are anode (+) and cathode (-).

When building electronic circuits, you will work with a number of basic electronic components, including resistors, capacitors, diodes, transistors, inductors and integrated circuits. Below is a brief overview of the components and their functions.

Switches interrupt current. The four types of switches are: single pole single throw (SPST), single pole double throw (SPDT), double pole single throw (DPST) and double pole double throw (DPDT).

I would need this display to be on continuously, if it has to be blacked-out and have time-outs frequently, this may not be what I need.

When using the e-Paper display, it is recommended that the refresh interval be at least 180s, and refresh at least once every 24 hours. If the e-Paper is not used for a long time, you should use the program to clear the screen before storing it. (Refer to the datasheet for specific storage environment requirements.)

No, I'm using much smaller displays. My budget isn't big enough to invest in something like that unless I actually need it. I have two, close to 1.9" diagonal units. One is 5V compatible, the other one is only 3.3V capable.

Transistors: These components are easy to identify through their three terminals. For the components to work, voltage has to be applied to one of them; the base terminal. The base can then control current flow in the two other terminals (the emitter and collector).

Inductors: These are passive components that store energy in form of a magnetic field. An inductor simply consists of a coil of wire wound around some kind of core. The core could be a magnet or air. When current passes through the inductor, a magnetic field is created around it. The magnetic field is stronger if a magnet is used as the core.

Circuit Breakers: As a protective device, a circuit breaker can be controlled with a remote switch. It is designed to protect the circuit from overloading or a short circuit.

Diodes: Diodes allow electric current to flow in a single direction only. Each diode has two terminals known as the anode and cathode. When the anode is charged with positive voltage and the cathode with a negative one, electric current can flow. Reversing these voltages will prevent the current from flowing.

Fuses help preserve components from overloading with excessive current. A fuse consists of connection body, support, contacts and metal-fuse material such as Zinc or copper. As a protective device, a circuit breaker can be controlled with a remote switch. It is designed to protect the circuit from overloading or a short circuit.

Integrated Circuits: An integrated circuit refers to a special device that has all the components required in an electronic circuit. The component has diodes, transistors, and other devices, all of which are etched on a tiny piece of silicon. The components are used in many electronic devices, including watches and computers.

That's great. How would the refresh rate be? One video here using a 7.5" made an issue over screen-burn-in, is this a real problem?

Microcontrollers: Microcontrollers are small computers used to control a multitude of devices, such as power tools, remote controls, medical equipment and office machines.

Are you using a 7.5" 3V/5V or 5V only version? Where did you find it? I'm seeing small 3v/5v displays but not the larger ones.

Resistors: A resistor is one of the components you will come across in an integrated circuit. Like the name suggests, the device resists the flow of current. Resistors are graded based on their power ratings (amount of power they can handle without exploding) and resistance values (capacity to resist current). The measurement is done in units know as ohms. The electronic symbol of the unit is O.

The product price signs in retail stores like Kohls, must not have a screen burn issue, as they are used for multiple products over their life, and don't have images burned from previous products.

Switches: Switches interrupt current. The four types of switches are: single pole single throw (SPST), single pole double throw (SPDT), double pole single throw (DPST), and double pole double throw (DPDT).

No such thing as "burn-in" because the tech is all "charged-based"; but sometimes, the refresh on my Waveshare units will leave a "ghosting" because the black/white spheres do not fully migrate front-to-rear quickly. Eventually, the issue seems to clear up. (may be room temperature related in that basement lab is about 10 F degrees cooler.

Capacitors: These components can store electric charge temporarily. The components come in different varieties, with the most common ones being electrolytic and ceramic disk. The capacity of a component is usually measured in microfarads (µF).

Relays are electromechanical switches that shut power on or off. A relay includes an electromagnet, an armature, a series of electrical contacts, and a spring.

After the screen enters sleep mode, the sent image data will be ignored, and it can be refreshed normally only after initializing again.

I worried a little about burn in, because it came to me with a crappy factory pattern, I thought, I'd better hurry up and find something to clear it. But it turns out, it can safely maintain the same image for months or years.

What are active and passive components in electronics? Active components include transistors, while passive components include transformers, inductors, resistors, capacitors. Transformers are commonly used to step up or step down power. A resistor restricts current flow. It is used in thermistors and potentiometers. Similar to a low capacity battery, a capacitor allows delays to occur in circuits. Inductors are used to control frequencies.

I have a small array of sensor data (collected by an UNO) I would like to display on a larger screen, like 7.5 inch, that can be seen a meter or two away. I would like to use an e-Paper display directly connected to a Mega or Uno (With clean fonts of a chosen size) if possible. Or is this a Raspberry Pi fed by a Uno feat, or?

Anything, any write. It's inherent in the display technology. Also there are finite write cycles. I considered a clock, but the seconds count would kill it before (I can't recall the exact interval) any useful time span.
