ePaper Insight Industry News, March 14-17, 2024, the Appliance & Electronics World Expo (AWE) was grandly held at the Shanghai New International Expo Center. At this expo, Hisense Group unveiled its dynamic display refrigerator product for the first time, which is equipped with the E Ink Prism™ 3S color e-paper display supplied by Yiwu Qingyue.
The technology of Hisense’s dynamic display refrigerator door represents a breakthrough application in the field of electrophoresis. It utilizes E Ink Prism™ series color-changing e-paper materials, where the key to color-changing display lies in the pigment particles within the microstructure, which carry positive and negative charges. When different voltages are applied to change the microstructure’s electric field, the color particles move accordingly, thus presenting different colors. This technology allows the refrigerator door to change its appearance at any time and maintains the displayed image without consuming any power after the color change.
The color-changing appearance technology enables consumers to freely choose and customize the appearance of the product, creating a unique personalized style. This customization meets the aesthetic and individual needs of different consumers, allowing them to better express their unique tastes.
Hisense’s introduction of color-changing e-paper display technology aims to create a more personalized and creative visual experience for users of smart refrigerators, making the product more attractive and impactful. In the future, with advancements and upgrades in technology, users will be able to easily achieve creative designs, presenting unique patterns and information displays in addition to changing the refrigerator door’s color. By satisfying users’ pursuit of personalization and creative expression, Hisense not only provides an outstanding smart refrigerator but also creates a new lifestyle for users.
The e-paper display technology employs a reflective display solution, which does not emit light and does not require a backlight. It achieves display through the reflection of ambient light, providing a display effect similar to traditional paper. Even when the power source is removed, the image can still be displayed continuously, consuming only a small amount of power when changing the image, thus featuring extremely low power consumption.
Yiwu Qingyue Optoelectronics Technology Co., Ltd. is a wholly-owned subsidiary of Suzhou Qingyue Optoelectronics Technology Co., Ltd. (stock code: 688496). Established in March 2020, it is located in the Yiwu National Technology Business Incubator—Yiwu Technology Entrepreneurship Park, and is a high-tech enterprise specializing in the research and industrialization of cutting-edge displays such as e-paper. With accumulated experience in technology research and production in the small and medium-sized screen display panel industry, the company began construction of its e-paper module production line in March 2020, quickly entering the e-paper display field.
As e-paper develops towards larger sizes, colorization, and flexibility, the display effects of future products will become more diverse, and the application range will gradually expand to various fields such as home appliances, smart locks, decorative walls, and billboards. At this expo, the large-size e-paper color-changing technology was successfully applied to Hisense’s dynamic color refrigerator, marking an important breakthrough in the application of e-paper in the home appliance sector and paving the way for more extensive future markets.
