1 Product profile
The EL640.400-C2, -C3 and -CD3 displays are VGA-compatible high-resolution Thin Film
Electroluminescent (TFEL) 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 allows addition of features or reduction in overall size. The two
displays are mechanically identical.
The EL640.400-C2, -C3 and -CD3 are timing-compatible with the EL640.400–CB series
displays and signal-compatible with a VGA feature connector supporting the 350 and 400 line
standard VGA modes. They may be driven at frame rates up to 80 Hz.
The displays require +5 V

power input and four to five basic input
signals to operate:
 Video Data or pixel information
 Video Clock, pixel clock, or dot clock
 Horizontal Sync
 Vertical Sync
 Blanking in VGA timing modes
2 TFEL technology
A display consists of an electroluminescent glass panel and a mounted circuit board with
control electronics.
Figure 1. TFEL technology
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 aluminum; 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.
