The high-quality multi-functional TFT colour display LISY4A (4.3”) has a considerable resolution (480 x 272 pixels) and colour depth (16.7 million) for the standard range. By default it is delivered with a touch panel. A PC programme serves to save images for the landing positions, arrows and operating state pictographs or texts on an SD card. It is controlled via the LiSA bus or in the conventional way. The touch operation or a separately connectable PC mouse help to switch between vertical and horizontal position of installation and to realise all further settings in the menu.
