Text displays
The display serves to present monochromatic – one-colour – floating text. Extra bright diodes ensure visibility outside even during sunny days. To set the text, only a basic computer or just a keyboard is sufficient – the rest of the time, after inputting the text, the device works independently. The memory of the device is large enough (20 000 signs) to satisfy even the most challenging needs. The memory does not erase even after the device has been unplugged.
