With the soaring international energy prices, the prices of coal, oil and natural gas in major international markets are 1.7 times, 2.6 times and 6.3 times of the same period of the previous year respectively, resulting in a significant increase in electricity prices in major international countries. The IEA believes electricity prices have been pushed to unprecedented levels, while pushing emissions from the power sector to record highs.

International electricity prices have risen sharply

At the end of 2021, the pre-day trading price of THE US PJM market increased by 153% compared with the same period at the end of 2020. The average transaction price in Britain reached 1.668 yuan/KWH, 4.3 times that of the same period in previous years; The average trading price of Germany and France was 0.956 yuan/KWH and 1.007 yuan/KWH respectively on the Nordic Power Exchange, about 2.9 times of the same period last year, and the current trend of rising.

At the end of 2021, China was hit by a wave of power rationing affecting many provinces across the country. Inner Mongolia, Ningxia, Shanghai, Zhejiang, Guangdong and other regions have successively started the adjustment of “price increase”, allowing the coal power market transaction price to float upward on the basis of benchmark price.

In this round of tight global energy supply and sharp fluctuations in power prices, it gives us an important revelation that the green energy transition is imminent, and it is the top priority to realize the gradual replacement of traditional energy by new energy and promote the smooth transition of green energy transition.

Unplugged screen – electronic paper display

Electronic paper, also known as electronic ink screen, is a display technology that has a similar display effect to paper printing. Electronic ink technology is the electronic ink coated on a layer of plastic film, and then attached to the thin film transistor (TFT) circuit, through the drive IC control, the final formation of pixel graphics.

The black-and-white e-paper display, for example, consists of millions of microcapsules, each containing electrophoretic particles, a negatively charged white particle and a positively charged black particle. If we change the electric field, the black or white particles in the corresponding region will move to the top, while the region will appear white or black when viewed from the outside. This is the basic principle of e-ink technology.

Based on this principle, e-paper displays are much more energy-efficient than other displays. In the case of no power supply at all, the picture can continue to display, will not disappear, only when switching the picture will consume a small amount of power, compared with the same size of the LCD, has excellent power saving performance.

With the development of the Internet of Things, keeping connected and saving power has become the biggest demand for each application scenario. E-paper display conforms to the trend of low energy consumption and intellectualization in many fields, so it is also regarded as the most ideal display in the Era of Internet of Things. At present, e-paper display has been widely used in new retail, office, logistics, education, medical care, transportation, mobile and wearable industries, adding new momentum to the development of smart city.

Four-color e-paper enriches the commercial display market

Four-color electronic ink system, using black, white, red and yellow particles, provide bright saturated four colors, can show rich and diverse information and content, at the same time shorten the picture refresh speed, increase the yellow and red applicable temperature range, in line with the higher requirements of diverse application environment.

Electronic paper with energy-saving, continuous display of zero power consumption, low carbon and green product characteristics, to assist the industry to strengthen the promotion, such as in public transport, display vehicle adjustment information, cautions and reminders; In department stores and retail stores, it pushes commodity promotion information and attracts consumers’ attention with bright red and yellow colors.

In addition, four-color electronic paper does not spontaneously light, but is displayed by reflecting environmental light source, which can avoid interference with the environment. It is also suitable for digital display scenes such as conference room nameplates, table cards, activity agenda cards, catering table promotion billboards, and bank counter information signs. Images and text displayed can be replaced through the mobile APP, which can quickly update the content in real time and save paper consumption and labor costs.

Benefiting from the deployment of global artificial intelligence, Internet of Things, smart cities, new infrastructure and big data, the global e-paper display terminal market will grow at a compound growth rate of 50.6% in the next five years and exceed $60 billion in 2025. As a new electronic paper display technology manufacturing service provider in the field of Internet of Things, DKE Will continue to make efforts in electronic paper products and technologies, and help to develop broader market prospects and development space.
