The series we are talking about here is an LCD dotmatrix series complete with a control interface and bezel. The LCD module, which includes an RS-232 interface, is delivered as a unit. It is connected to a standard RS-232C interface (or, alternatively, an RS-422).
You will find more information on this on the rs232 page.


  • Bezels
    All bezels are available with an anti-glare screen. The bezels are simply inserted into the frontal cutout. This gives your unit a professional look, and at the same time the anti-glare screen prevents the integrated display from being touched or getting dirty. The anti-glare screen makes the display considerably easier to read. Please refer to the tables for dotmatrix modules for the order numbers of the various bezels. You will find more information on bezels in our data sheet, which is available in PDF format, or on our accessories page.

  • Inverters for CFL- and EL-foil illumination 
    In contrast to LED illumination, CFL and EL illumination requires a series-connected electronic circuit. This electronic circuit, which is known as an CFL inverter and EL inverter, generates alternating voltage of some hundreds Volt from +5V DC. These inverters have 3-5 pins that are soldered into a printed circuit board. The type required depends on the illumination surface. You will find more information on our accessories page, our news page or in our data sheet, which is available in PDF format.

  • Cables and connectros 
    We accept orders of one or more units of the following items for your display: one- or two-row connectors and cables with a grid of 1.27 or 2.54 mm with a female connector (one- or two-row) crimped on, with different numbers of pins and a wide range of lengths.
