Product profile
The EL512.256–H3 series displays are rugged, high-resolution thin film electroluminescent
(TFEL) flat panel displays. They feature an integrated DC/DC converter, and their compact
dimensions save space that allows addition of features or reduction in overall size. They are
designed to work in extreme environments and the crisp display is viewable at wide viewing
angles both in horizontal and vertical directions. Their ease of installation reduces system
integration costs.
The EL512.256–H3 is a 512 column by 256 row flat panel display with a 1:1 pixel aspect
ratio. The digital flat panel interface is designed to match the needs of most systems. The
displays may be driven at frame rates up to 75 Hz.

EL technology
Figure 1. EL technology
A display consists of an electroluminescent glass panel and a mounted circuit board with
control electronics. The TFEL glass panel is a solid-state device with a thin film luminescent
layer sandwiched between transparent dielectric layers and a matrix of row and column
electrodes. The row electrodes, in back, are aluminium; the column electrodes, in front, are
transparent. The entire thin film device is deposited on a single glass substrate. The glass
panel is mounted to an electronic circuit assembly board (ECA) with an elastic spacer. The
ECA is connected to the TFEL glass panel with soldered lead frames. The result is a flat,
compact, reliable and rugged display device.
In the EL512.256–H3 series displays, the 512 column electrodes and 256 row electrodes are
arranged in an X-Y formation with the intersecting areas performing as pixels. Voltage is
applied to both the correct row electrode and the correct column electrode to cause a lit
pixel. Operating voltages required are provided by an integral DC/DC converter.
