LED display system for use at e.g. public place, to display advertisement, has control device provided for automatic control of adjustment movement of one of LEDs or one group of LEDs relative to adjacent LED and/or adjacent group of LEDs

摘要

The system has an LED matrix (1) comprising LEDs (3) that form an LED array (2) and are individually controllable, where the LED matrix comprises groups of LEDs for displaying pixel images. Two of the LEDs and/or two of the groups are arranged adjustably relative to each other in such a manner that a distance between the LEDS and/or between the groups of LEDs is changeable. A control device is provided for automatic control of the adjustment movement of one of the LEDs or one group of the LEDs relative to an adjacent LED and/or relative an adjacent group of LEDs.
