  • LCD modules with a bezelEA 017-xxU series
    The bezels of the EA 017-xxU series are made of black ABS material to UL 94 V0 (up to 100°C, self-extinguishing, non-combustible) with a scratch-resistant, structured surface. They contain a snap-in mechanism for mounting a wide range of plates with a thickness of 1mm. The plates can thus be easily replaced, as required. A front plate can also be delivered with the specified bezels (clear plexiglass, anti-glare plexiglass or glass).
  • EA 017-xx series
    The bezels of the EA 017-xx series have a matt black, coated surface and an undercut at the back for sticking on plexiglass plates with a thickness of 1-2mm. The specified bezels can be delivered optionally with or without a fitted plexiglass plate.
  • EA 027-xxKE series
    The bezels of the EA 027-xxKE series are made of anthracite-colored ABS material. They are delivered exclusively with a replaceable, anti-glare plexiglass plate. They are delivered in packs of 10.

You can download a data sheet containing details of all of the bezels here as a PDF file.

RS-232 interface
Many dot-matrix and graphics LCDs have only one option for connecting to an 8-bit data bus. If the data is to be transmitted serially (lack of ports, considerable distance), it is advisable to use an RS-232 interface. This interface then also handles the initialization and line management of text displays. Using an interface also considerably reduces the programming effort required with graphics displays as well.

  • EA 9706 RS-232 interfaceRS-232 interface for dot-matrix displays
    The EA 9707-V24S board is suitable for all dot-matrix LCDs with HD 44780 (1x8 to 4x40 characters). It is a mere 80x32x14mm in size. The RS-232 connection is provided by a 10-pin connector, and there are 3 different 1- and 2-row soldering-eyelet strips available for connecting the display. The transmission rate can be set to 300, 1200, 2400 or 9600 bps. There is a contrast potentiometer on board. The supply voltage is +5V or +9-35V. You can download the full data sheet in PDF format here immediately. The price if you order 25 is 44.37 euros*) per item. An RS-422 interface and an integrated fixed-text memory for 64 pages with 6 digital inputs are available as options.

*) Prices quoted are inclusive of 16% sales tax.

  • RS-232 interface for graphics displays
    We can provide a suitable RS-232 interface for practically any graphics LCD in our range. We also offer some displays as fully configured graphics units. The different displays have resolutions of between 120x32 and 640x480 pixels. Each interface has a variety of integrated fonts and graphics functions that considerably simplify graphics programming, which can otherwise be really quite complex.

EL foild with EA PSEL-22 inverter EL foils
permit extremely even lighting covering areas from a few cm² to several hundred cm². They are very thin (approx. 0.4mm) and available in a wide range of colors. Standard EL foils are generally available in any quantity as of 1 item only. Color: blue-green (turquoise) except EA LF-08W: white. EL foils require an alternating voltage of 80-120V for operation. This is provided by an EL inverter. Since EL foils are subject to a certain aging process, a half-value period of 5,000 to 10,000 hours is specified for their lifetime. The foil is half as bright by the end of this period. You can download a detailed data sheet in PDF format here immediately. ELECTRONIC ASSEMBLY supplies a minimum of 250 customer-specific EL foils in the size and color you specify. In order to respond to your inquiry, we need to know the following: external dimensions, color, quantity and batch size.

EL/CFL inverters

  • EL inverters
    EL foils are operated with alternating voltage. The required voltage is between 80 and 120V, and the frequency range is 50Hz to 1kHz. Suitable EL inverters are available for operating an EL foil in a 5V= or 12V= system. The selection is made simply by calculating the area to be illuminated in cm². A “large” EL inverter can thus also be used with a number of “small” EL foils.
    The full data sheet for EL and CFL inverters can be downloaded here in PDF format.
  • CFL inverters
    Cold-cathode tubes work in essentially the same way as neon tubes; in other words, they require a few kV to ignite and 1-300V to operate. Here, too, a series-connected electronic circuit is required. These are available for supply voltages of 5V=, 12V= and 24V=.
