Display device for industrial automation device, has light-emitting element i.e. LED placed in LCD display cell, where control unit controls LED in response to environmental parameters of LCD display cell and wall detected by sensor unit

摘要

The device has an LCD display cell (1) for displaying visual information on a viewer facing side (2), where the LCD display cell is arranged in front of a wall (3). A light-emitting element i.e. LED (4) is placed in the LCD display cell, and a sensor unit (5) is assigned to the LCD display cell for determining the parameters in the environment of the LCD display cell and the wall, and for determining other characteristics of the reflection surface. A control unit controls the LED in response to the detected environmental parameter from the sensor unit.
