Abstract
A display device includes a plurality of cells arranged in a two-dimensional matrix and including luminous elements and feedback elements arranged in the cells. A control device emits control signals to control the luminous elements individually in accordance with a setpoint control pattern. An evaluation device receives from the feedback elements feedback signals depending on actual control states of the luminous elements and determines a feedback pattern based on the feedback signals. The evaluation device then compares the feedback pattern with the setpoint control pattern and producing a normal reaction when the feedback pattern matches the setpoint control pattern, and producing a fault reaction that is different from the normal reaction when the feedback pattern fails to match the setpoint control pattern.
