Abstract

An electronic display apparatus comprising a control device and an electronic display panel that can be turned off by the control device. In order to support an energy-saving state in which information can continue to be displayed at least to a certain extent, an electrochromic display is additionally provided that is switchable into different display states by the control device. The invention furthermore relates to an installation appertaining to automation technology, and to a method for operating an electronic display apparatus.

Claims16

Dependent claims

An electronic display apparatus, comprising:

a control device;
