Brief Introduction and Application of the Electronic Ink Display

In 2007, Amazon released the first-generation e-reader Kindle, which was equipped with a 6-inch 4-stage e-paper ink screen. With the popularity of Kindle, electronic paper is truly known to consumers.

Electronic Paper (Electronic Paper), referred to as ePaper, is an digital paper display technology that can imitate the visual perception of printing and writing on paper.

Electrophoretic ink (electrophoretic ink) technology is generally called electronic ink (electronic ink). The electronic ink is coated on a layer of plastic film, and then covered with a thin film transistor (TFT) circuit, which is controlled by a driver IC to form a pixel pattern, creating an electronic paper display (EPD).

Unlike ordinary flat-panel displays that display images with luminescence, e-paper mostly uses electrophoresis display (EPD) as the display panel, which relies on reflected ambient light to display images, which is more comfortable to read, and the displayed images can be clearly visible under direct sunlight with extremely wide viewing angle.

E-paper is flexible with low power consumption, which is widely used in various fields of life such as reading and writing, mobile wear, electronic shelf labels, electronic billboards, architecture and design.

The broad prospects of an electronic ink display should lie in smart and Internet of Things applications. E-readers, ink screen labels, electronic paper wear, ink screen education, ink screen medical treatment.

1. Application of electronic ink display in intelligent transportation

The display effect of the electronic ink display in the sun is much better than that of LCD and LED, and the effect during the day is very clear; secondly, the ultra-low power consumption of the ink screen means that solar power or charging can be used, which eliminates the need to pull the municipal electricity. You don't need to dig bricks and the ground for wiring, you can use it directly, saving a lot of trouble and cost of installation and transformation.

2. Application of electronic ink display in smart retail

Now large supermarkets or new retail brands have been promoting the use of ink screen price tags. The biggest role of this type of IoT tags is that it can be managed in the background, in batches, become digital, and management is more refined. The ultra-low power consumption of the ink screen makes it possible to digitize these printed labels.

3. Application of electronic ink display in smart medical and office

Similar to the above three scenarios, office station cards, conference room cards, conference table cards, office electronic notebooks, electronic medical bed cards, and medical tablets, etc., are also suitable for the electronic ink display.
