Unlike the screens we see every day in smart electronics such as mobile phones and tablet computers, the display function of an e-ink screen relies on a "microcapsule" that can display colour, which is about the same diameter as a human hair, generally between 0.06-0.09 mm, i.e. 60-90 microns. Countless microcapsules are mixed together to form a display layer called the "ink film", or ink screen. In the case of a black and white e-ink screen with a two-colour display, each microcapsule consists of a white particle with a positive charge, a black particle with a negative charge and a suspension that fills the space between. The content of the e-ink screen is rendered by applying different electric fields to each microcapsule to change the position of the black and white particles in order to achieve an imaging effect. Once the pattern has been imaged, the position of the pigment particles in the microcapsules will not change again for a short period of time, resulting in a very stable image.

Advantages of e-ink screens.

Electronic ink screen reader, power saving and long life

Power saving is a key feature of e-ink screen readers. Once the content is refreshed, it remains on the display and can be read normally without a power supply for subsequent reading.

In other words, e-ink screen readers do not consume power when they are displayed, but only when they are powered up and refreshed, so the power supply lasts longer than conventional displays. This means that in work life and outdoor use, the user customer does not have to worry about the power supply at all.

Visible in bright light, protecting eyesight

The black and white contrast of the e-ink screen is very high, so it is still clearly visible in bright light. It looks like real paper, without the reflections like LCD screens, and is instead seen more clearly in places with strong light.

Now the label, in addition to common paper content, most of us can see is done on smart devices, basically have a backlight, these devices have a certain degree of strobe, long time reading will make people's eyes fatigue, vision will be affected, as opposed to the display screen shows the content of reading, because the e-ink screen is a natural reflection display without backlight, so there is no blue light and screen flash hazards of mobile phone screens The ink screen is similar to paper.

The benefit of this paper book-like reading experience is that it allows for more focused reading and long periods of staring without dry eyes, which can play a good role in protecting your eyesight.

Flicker-free, radiation-free, large viewing angle

Conventional LCD screens flicker because they are constantly being refreshed, and although the naked eye may not be able to detect this, the phenomenon exists objectively and is a major cause of eye fatigue caused by viewing the screen. But the electronic ink screen due to its innate advantage of the working principle, once the screen refreshes there will be no more changes, but also greatly reduce the eye fatigue.

The use of IoT technology electronic ink screen label wisdom management warehouse, warehousing logistics production line and other scenarios can liberate staff work pressure, improve efficiency; use electronic ink screen IoT industrial label instead of paper label display information; and can be seamlessly docked with the information system, through the IoT industrial electronic label, the production link in the material information directly interact with the enterprise information management system. Computer operation to modify shelf management information, simple and convenient, improve work efficiency, reduce labour costs and the probability of human error.
