Product Profile
The EL640.480-A SB series displays are VGA compatible high-resolution
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 can allow addition of
features or reduction in overall size. The displays are mechanically identical.
The display format of EL640.480-A SB series displays is VGA compatible (640
columns by 480 rows) with sixteen true shades of gray. The display supports
and automatically detects all standard VGA modes.
The displays require a 12Vdc power source and five basic types of
input signals to operate :
1. Video Data or pixel information
2. Video Clock, pixel clock, or dot clock
3.
Horizontal Sync
4.
Vertical Sync
5.
Blanking
EL Technology
The display consists of an electroluminescent glass panel and a mounted
circuit board with addressing 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 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 with an elastic spacer to an
assembly support carrying the electronic circuit assembly board (ECA)
mounted on the support. The driver electronics is connected to the EL glass
panel with soldered lead frame interconnects. The result is a flat, compact,
reliable and rugged display device.
