Abstract

The invention provides a display device and a manufacturing method thereof. The display device is provided with a display device body and a coating located on the surface of the display device, and the coating contains nanometer calcium tungstate. The coating containing nanometer calcium tungstate is arranged on the surface of the display device body so as to play an antiviral role, have a virus inhibiting function, be beneficial to providing the healthy life for human beings and further improve the quality of life. The virus includes but not limited to murine herpetoviruses(MHV-68), murine coronaviruses (MHV-A59), avian influenza viruses (H9N2) and the like.

Description

technical field [0001] The invention relates to a display device and a preparation method of the display device. Background technique [0002] Due to exposure to the surrounding environment, the display devices of medical equipment and mobile display devices such as mobile phones, tablets, and laptops may breed viruses and reproduce and grow, and these display devices are often in repeated contact with the human body, thereby It will become a medium for virus transmission, which may endanger the health of more people. [0003] Therefore, there is a need for a display device that is resistant to viruses. Contents of the invention [0004] Therefore, the technical problem to be solved by the present invention is to provide a display device capable of anti-virus. [0005] In order to solve the above technical problems, the present invention provides the following technical solutions. [0006] Specifically, the first aspect of the present invention provides a display device...
