ELECTRONIC PROTECTIVE MEASURES FOR ORGANIC DISPLAYS IN SMALL MEDICAL INSTRUMENTS

摘要

The invention relates to a medical appliance (110) having an electrical energy supply (130) and a display unit (122) for optically depicting information. The display unit (122) comprises a display (124) having at least one organic light-emitting material and is configured to be supplied with electrical energy by means of the electrical energy supply (130). The display unit (122) further comprises an activation device (126) for activating the display (124), and a display driver (140). The activation device (126) is configured to activate the display (124) in a regular operating mode for depicting the information. The activation device (126) comprises a protection circuit (186) that is configured to monitor an electrical signal provided by the electrical energy supply (130) and, in the case of a deviation of the electrical signal from the normal range, to switch the display unit (122) to a safety state.
