Description

Electronic display device and method for sterilizing the same Technical Field The present invention relates to an electronic display device and a method for sterilizing an electronic device. Background Electronic display devices are known, for example, from WO2019076447A1 and are used in order to provide information graphically as images and/or text. Such electronic displays are used as electronic product display devices and/or price display devices, particularly in the retail industry. During this time, electronic display devices are also increasingly being used in hospitals, care facilities, and the like to supply information to staff and patients. In these applications, maintenance of the electronic display device is important. Thus, electronic display devices must be cleaned periodically in order to inhibit or avoid the transmission of potentially harmful pathogens, which is currently very time consuming and labor intensive. The present invention has therefore been made in an effort to provide an electronic display device and a method that overcome the above-mentioned problems. Disclosure of Invention This object is achieved by an electronic display device according to claim 1. The subject of the invention is therefore an electronic display device having a screen, in particular a reflective screen, for displaying information and having a disinfection device which is designed to disinfect at least one sub-region of the electronic display device, in particular the outside of the electronic display device. This object is furthermore achieved by a method according to claim 15. The invention thus relates to a method for disinfecting an electronic display device by autonomously disinfecting a sub-area of the electronic display device by means of a disinfecting device integrated into the electronic display device. The measures according to the invention are accompanied by the advantage that the effort for maintenance is drastically reduced both in the sense of effort and in the sense of time. Furthermore, a constant quality during sterilization can thus be ensured, since sterilization is performed autonomously, in particular (fully) automatically, and thus human errors or inaccuracies are avoided. Further particularly advantageous embodiments and developments of the invention emerge from the dependent claims and the following description. The effects and advantages mentioned in connection with the device are also presented in the corresponding method claims. Disinfection is understood to mean that an inanimate or living substance is placed in a state such that the substance is no longer capable of infection. The effectiveness of disinfection can be classified on a "log10 scale", in particular on a so-called "log1 to log8" scale, which illustrates how the number of viable (lebensf ä hige) microorganisms decreases drastically during the disinfection process. For some use cases, it has proven advantageous that the electronic display device is configured at least for achieving a 1-log10 level of bacterial reduction, i.e. a reduction of 90% of viable microorganisms. This is advantageous, for example, for use of the electronic display device in a commercial area (Gesch ä ftsbereichen) in order to keep the bacterial count low between conventional cleaning schedules (Reinigungstermin) of the commercial area. For some use cases, it has proven advantageous that the electronic display device is configured at least for achieving a 2-log10 level of bacterial reduction, i.e. a reduction of 99% of viable microorganisms. This is for example advantageous for the use of the electronic display device in a nursing home in order to keep the bacteria count low between the regular cleaning schedules of the room. For some use cases, it has proven advantageous that the electronic display device is configured at least for achieving a 3-log10 level of bacterial reduction, i.e. a reduction of 99.9% of viable microorganisms. This can be used, for example, in order to prevent spores from germinating. In addition to the previously mentioned use cases, this is advantageous, for example, for the use of electronic display devices in medical clinics in order to keep the bacterial count low. For some use cases, it has proven advantageous that the electronic display device is configured at least for achieving a 4-log10 grade bacterial reduction, i.e. a reduction of 99.99% of viable microorganisms. This can be used, for example, in order to prevent spores from germinating. In addition to the previously mentioned use cases, this is advantageous, for example, for the use of the electronic display device in an intensive care unit in order to keep the bacterial count low. In addition to the previously mentioned use cases, this is also advantageous, for example, for the use of the electronic display device in a hospital kitchen in order to keep the bacterial count low. For some use cases, it has proven advantageous that the electronic display device is
