On April 26th, Guangzhou AoWing Electronic Technology Co., Ltd. was informed that the company and Chongqing Mesh Technology Co., Ltd., after a year of joint development, successfully developed the world's first graphene electronic paper, and it is expected that graphite can be realized within six months. Electronic production of vinyl paper. It is understood that this graphene electronic paper can be combined with a flexible or rigid drive backplane to produce a rigid graphene electronic paper display and an ultra-flexible graphene electronic paper display.
Compared with the traditional electronic paper, the graphene electronic paper has the following three advantages: First, the bending ability is stronger, the strength is higher, and the application of the electronic paper display screen is further widened, which is very suitable for wearable electronic devices and objects. Networking and other fields that require ultra-flexible displays. Second, ITO thin films are usually made of rare metal indium, which is not only expensive, but also has a small amount of storage and there is a risk of shortage. Graphene can not only reduce the cost of the product, but also the graphite material is inexhaustible. In addition, due to the high light transmittance of the graphene material, the brightness of the electronic paper used to display it is better.
Graphene is a two-dimensional crystal. The single-layer graphene has a thickness of only one carbon atom, ie, 0.335 nm, which is equivalent to a thickness of 200,000 parts of a hair. There are about 1.5 million layers of 1 mm thick graphite. Graphene. Graphene is known as the thinnest and hardest material, almost completely transparent, and has an extremely high specific surface area, superior electrical conductivity, and flexibility. Although all countries in the world are conducting research on the application of graphene, graphene has not yet been widely used in industrial applications on a global scale. Wing Yi Electronics and Chongqing Moxi signed a technology development cooperation agreement a year ago. AoWing Electronics developed graphene electronic paper using graphene materials provided by Chongqing Moxi. The success of this graphene electronic paper has made China a major step forward in the industrial application of graphene materials, marking the fact that China has already taken the lead in the application of graphene. At the same time, flexible electronic paper technology has been further developed, and the application range of electronic paper display technology has been greatly expanded.
