The EL640.400–CB1/3 and –CD4 displays are VGA compatible high-resolution
electroluminescent (EL) flat panel displays.They replace the bulky CRT in
control and instrument product designs. They feature an intergrated DC/DC
converter, and their compact dimensions save space that can allow addition of
features or reduction in overall size. The three displays are mechanically
identical.
The displays are timing compatible with Planar EL640.400–C3/CD3 displays
and signal compatible with VGA Feature Connector supporting the 350 and
400 line VGA modes. They may be driven at frame rates up to 72Hz.
The displays require +5Vdc and +12 or +24Vdc 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 or Blanking
4. Vertical Sync
Planar EL displays consist of an electroluminescent glass panel and a mounted
circuit board with control electronics.
Figure 1. EL Technology.
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 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 EL
glass panel with flexible interconnects. The result is a flat, compact, reliable
and rugged display device.
