Why we need E-paper display? Future trend you need know

 

Electronic paper display (EPD or E-paper display, Chinese name is also called electronic ink screen, ink screen) in recent years, with the continuous development

of Internet of Things technology, the scope of involvement has continued to expand, and gradually entered the field of vision of more and more people.

The mainstream or most of the electronic paper displays (electronic paper/e-paper) that you see now refer to the series of products developed by the

electrophoresis technology held by E Ink Holdings. Simply put, electrophoretic display technology relies on charged ink microcapsule structural units coated with

black or white (so you may also come into contact with concepts such as microcapsule, electronic ink) to move under the action of an applied voltage to

form an electric field, One cell is one pixel, so you get a white, paper-like display.

 

The main advantages of electronic ink screen are as follows:

1. Paper-like display. In 2022 this year, the paper-like display index was also promulgated to measure the degree to which the display effect of a screen

is close to paper quality. It can be seen that E-paper display is a trending product.

 

2. As a typical bistable display, in addition to the paper-like display screen, the EPD can truly retain the displayed screen indefinitely even if it is no longer

powered on. This feature has been widely used in many fields, such as electronic conference table cards, electronic house cards, electronic goods labels,

NFC, RFID passive logistics labels, etc. More and more technology companies are trying to combine this feature to Develop new products.

 

3. Low power consumption, green and environmentally friendly, because the characteristics of the bistable display and the characteristics of its own display

principle (reflective display, it does not require a backlight source) determine that the power consumption of E-paper display is very low when it is driven.

We have countless buyers who come here because of the ultra-low power consumption of E-paper display! If you value low power consumption and want to build a

device with low power consumption, E-paper display is definitely a choice you cannot miss. 2022 is the first year of the e-paper explosion, and E Ink corp also obtained

carbon footprint certification in the second half of the year. In order to commend the outstanding contribution of the electronic paper industry led by E Ink in the great

practice of achieving zero carbon emission. Choosing a EPD display is to contribute a small amount to the cause of human environmental protection.

 

4. Wide viewing range close to 180°. The EPD is used as a reflective display. Similar to paper, it can be easily seen by the eyes only by diffuse reflection without self-illuminating

light sources. This feature has been around since the era of e-readers Favored by readers, In 2022, major manufacturers are now entering E-paper display tablet market one

after another. One of the reasons for the display track is because of its huge advantages in eye protection. In addition to the traditional display field, in smart education and

other tracks, we have also witnessed many products developed to ensure that young people can learn more efficiently and healthily, such as electronic word cards,

electronic student ID cards, and EPD for student-learning devices. Eye health has never been a topic that few people care about. China is a big country with myopia.

How many students in our classrooms did not wear glasses when they were students?

The growing vision problem is urgent, but we hope to see this problem improved because of the EPD!

 

5. The artistry that other traditional display screens do not have, the unique display effect of the EPD has a high aesthetic appreciation value,

such as black and white monochrome/black and white red three-color/seven-color E-paper display photo frames, or traditional famous

paintings engraved on E-paper display (Specifically, you can Google related keywords, foreign technology companies have precedents)

You can give full play to your imagination to make the E-paper display have more possibilities.

 

Next, we will talk about how the ink screen plays a key role in the Internet of Things:

More and more systems are using Internet of Things (IoT) and Industrial Internet of Things (IIoT) nodes. In these systems, the security of the entire network is more

important than the functionality of individual devices on the network. This means that if an IoT node has been compromised or has an irreversible firmware error,

it is safe to shut it down as soon as feasible to avoid potential danger to the node and the network.

 

But once the node loses power, everything in volatile memory is lost. If the debug data is stored in non-volatile memory such as EEPROM or FLASH, time and

power consumption increase the risk of potential corruption. In addition, if the power-on sequence is affected at the same time, it may affect the system,

resulting in that the readback data cannot provide reliable data during the power-on process.

EPD e-paper display easily connects to IoT or iiot nodes to display known bugs,

 

This provides a visual indication of the cause of a power outage event, providing diagnostic information in the event of low or no power consumption.

There are several reasons why the EPD electronic paper display causes the firmware of the single-chip microcomputer to fail:

The installed firmware code is wrong. An invalid calculation results in a failure; or, in rare cases, a hardware failure of the microcontroller.

Often, well-written firmware can detect failures by clearing inputs to subroutines and functions. If the firmware is locked or stuck in a loop, the watchdog

timeout will restore the firmware by jumping to an error control subroutine or performing a hard reset of the microcontroller.

 

In case of invalid input data, such as failure or tampering of external sensors, it may cause data overflow without proper consideration in the application code.

For example, if the ambient temperature sensor falsely registers a high temperature of 250°F in a human-controlled room,

This could be sensor malfunction or malicious tampering. Careless firmware programmers may not code for such high temperature readings, which could cause

minor issues like erroneous data logging, or serious mishaps like allowing intruders to enter secure areas, Or critical control algorithm calculation errors leading to

equipment failure or serious personal injury. The potential negative outcomes are many. In addition,

the EPD electronic paper display can use an external circuit to interrupt the power supply of the microcontroller;

 

However, this increases the complexity of the system, resulting in reduced reliability. Therefore, offline control of the firmware is an option for the microcontroller.

The above is an application scenario of E-paper display with practical significance. You can clearly understand that the configuration of

E-paper display retains key information in a very difficult and troublesome situation, which facilitates subsequent technical investigations.
