Epaper (electronic ink screen) is an electronic display using electronic ink technology. It has the advantages of low power consumption, high contrast, and good readability. It is especially suitable for e-books, electronic journals, electronic newspapers and other fields. A variety of technologies and materials are required to make Epaper. These aspects will be further discussed below, and the production cost and service life of Epaper will be analyzed.

1. Epaper production technology

 

1. Electronic Ink Technology

Electronic ink technology is the core technology of Epaper, which uses a tiny electric field to activate ink particles to display patterns or text on a paper-like background. The e-ink particles of an e-ink screen are wrapped in a capsule, and the capsule is surrounded by electric charges. When an electric field is applied to both ends of the capsule, the ink particles inside the capsule split into two poles, one with a positive charge and the other with a negative charge, causing the two-colored capsule blocks to appear. This technology is called electronic ink technology. Compared with liquid crystal display technology, it can significantly reduce power consumption, and erasing and updating display content only requires one electric field switch.

 

2. Thin film transistor technology

Epaper's row and column drive circuit is composed of thin film transistors (TFTs). Thin film transistors are programmable electric valves that control the arrangement of liquid crystal molecules. Different electric fields specify different voltage levels, which will cause the liquid crystal molecules to form different molecular arrangement states during conduction, thereby achieving precise pattern, character or image display.

Thin film transistor technology is of great significance to the stability and high integration of Epaper. The use of thin film transistor technology can achieve high-speed driving and larger gray levels at very small transistor sizes. In the manufacturing process of Epaper, multiple technologies such as double glass shell processing and heating injection technology, ITO flexible transparent electrode preparation technology, and composite laminated LSPS transfer technology are also required.

3. Wiring design technology

Wiring design is one of the indispensable links in Epaper production. There are millions of pixels in the Epaper screen, so to adapt to complex circuit design in a small space, designers need to fully understand a series of circuit aspects such as circuit design, impedance matching, and signal transmission. At the same time, digital optoelectronic technology based on Epaper is increasingly used in other industries, such as scientific research, industrial control, medical diagnosis, etc., and wiring design technology is also constantly improving and improving its applicability.

 

2. Selection of Epaper materials

 

1. Battery

Epaper's display requires power support. Common batteries include lithium-ion batteries, nickel-hydrogen batteries and lead-acid batteries. Lithium-ion batteries are generally considered to be the most suitable battery type for Epaper because they not only have high energy density and Environmental adaptability can also meet the needs of long-term standby and fast charging.

 

2. E-ink color

Different Epapers have different e-ink colors. For example, the electronic ink colors of common Epaper products can be black and white, red and black, yellow and black, etc. The more colors, the higher the price. Due to the characteristics of electronic ink, its color response speed is slow and it is not suitable for colorful animations that can be quickly switched.

 

3. Appearance materials

The appearance material of Epaper is also a very important material. Common materials include glass, plastic and metal, among which glass is the most commonly used appearance material, which can protect Epaper and prevent scratches.

 

4. Accessories

The use of Epaper depends on attachments. Some necessary accessories include packaging boxes, chargers, charging cables, instructions for use, etc. Different accessory options can also be provided according to user needs and Epaper types.

 

3. Production cost and service life of Epaper

 

The production cost of Epaper is relatively high, with the biggest cost being the screen, especially the printing cost of the new Epaper. Continuous development and innovation of production technology will also lead to continued cost reduction. Epaper has a longer service life and is longer than common monitors or electronic display products. This is because Epaper screens do not require lights or backlighting, and most of the time they are in a dormant state, which is very power-saving. Since it does not require constant power supply, it can last for many years.

 

In general, making Epaper requires the use of numerous technologies and materials, and has high requirements in terms of production cost and service life. Epaper has excellent battery life and extremely low energy consumption, reflecting its economic efficiency. Epaper is a green product, very environmentally friendly, and a powerful tool for saving resources and preventing global warming to promote sustainable development. In the future, Epaper may be more widely used in different industries and become an indispensable digital display technology.
