The EL512.256–H series displays are rugged, high resolution
electroluminescent (EL) flat panel displays. They replace the bulky CRT in
control and instrument product designs. They feature an integrated DC/DC
converter, and their compact dimensions save space that can allow 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–H 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.
The EL512.256–H displays require +5 Vdc and +11...+30 Vdc power input and
four basic input signals to operate:
1. Video Data or pixel information
2. Video Clock, pixel clock, or dot clock
3. Horizontal Sync
4. Vertical Sync

Figure 1. EL Technology.

A display consists of an electroluminescent glass panel and a mounted circuit
board with control electronics. The EL 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 EL glass panel with soldered lead frames. The result is a flat,
compact, reliable and rugged display device.
