Information

In fact, e-paper modules can be used in mobile devices and ultra-thin displays, mainly in print-related applications such as portable e-books and e-newspapers, as well as IC cards. Here is an overview of the advantages of the e-paper module. I hope it will be of good help to you when you make your purchase. The e-paper module provides similar reading functions and usage attributes to traditional books when in use, which is an advantage of e-paper. E-paper is very versatile and has the advantage of being thin and flexible. Of course, it is also possible to achieve both paper effects and display properties. What I want to tell you today is that e-paper modules can achieve the same reading comfort, lightness and flexibility as paper, as well as ultra-low consumption. E-paper is such a paper-based electronic display. E-paper modules have the advantages of paper. In addition to these characters, they can constantly switch and refresh the display content just like our common LCD displays. In a way, e-paper is also a kind of black technology. The display material of the e-paper module is very thin, flexible and has a surface structure similar to paper, resulting in a paper-like display and the ability to write. Such electronic paper can replace traditional paper and become a new generation of "paper".

Internationally, the e-paper module is mainly used to display patterns by reflecting ambient light and has the effect of paper printing. Compared with conventional transmissive LCDs, the e-paper module does not require a backlight and is easy to read. Even in sunlight, the e-paper display is still clearly visible. In addition, the e-paper module has a soft, glare-free and flicker-free display with a viewing angle of almost 180°. This makes the e-paper display ideal for reading. When using the e-paper module, we need to know that it can be compared to a normal LCD display. E-paper has a clear advantage in terms of thickness and weight. The reason for this, apart from its simple structure, is that e-paper itself is based on a soft plastic film. At the same time, this creates its natural flexibility and bendability. In addition, it can be cut into various shapes as required. These advantages of the e-paper module make it possible to "stick" to the surface of any product, regardless of its shape, size or structure. This meets the needs of the development of flexible display technology.

The e-paper display module is made up of the following materials:

E-paper diaphragm: This is the core material of the e-paper display module and is responsible for displaying the actual pattern seen by the human eye.

Base plate: This acts as the pixel electrode (lower electrode) of the e-paper display and is used to control the black and white variation of each pixel of the e-paper. There are various types of backing boards available, including PCB, FPC, TFT glass, PET, etc. Different backing boards can be selected according to the specific needs of the actual application.
The e-paper film can be laminated to the backplane.

Driver chip: It can generate the corresponding logic level and timing according to the control instruction and signal, which is used to control the working timing and status of each pixel (or segment code) of the backplane and enable the electronic paper to display the required pattern.

Transparent protective film : A polymeric plastic film with strong resistance to water vapour transmission. It is laminated to the electronic paper film and the backing board to prevent water vapour from penetrating the electronic paper film and to prevent damage to the electronic paper due to moisture.

Edge sealer: a special chemical glue that is applied evenly around the edges of the transparent protective film to isolate moisture. It prevents moisture from penetrating around the transparent protective film and damaging the electronic paper film.

For the sealing of the electronic paper module Vigon Technology has developed a graphene modified high toughness UV curing frame sealer. The product has fast curing, long dispensing process window, excellent water and gas barrier characteristics, good toughness of the adhesive layer, high adhesion to glass, metal, PET and other materials, and can be used for chip, electronic paper and other electronic components packaging.

Electronic paper module UV curing edge sealing adhesive has the following characteristics

1. Fast curing, low surface temperature

2. Good leveling and simple process

3. Excellent water and gas barrier properties

4. Flexible adhesive layer, adapt to the complex environment of hot and cold shock

5. Solvent-free, VOC-free, no air pollution, low irritation to respiratory tract

6. Dispensing time: light-proof, 25°C with dispensing machine
