Product Profile
The EL320.256–FD7 display is a low power, rugged, electroluminescent (TFEL) display which replaces the bulky CRT in control and instrument product designs. It features an integrated DC/DC converter, and its compact dimensions save space that can allow addition of features or reduction in overall size. It is designed to function in extreme environments, and its clear display is viewable under most lighting conditions at wide viewing angles. Its ease of installation reduces system integration costs.
The EL320.256-FD7 is a 320 column by 256 row flat panel display. The digital flat panel interface is designed to match the needs of most systems.
The display requires +5 Vdc and +11 to +30 Vdc (Vcc1, Vcc2) power and four basic signals to operate:
1.Video Data or pixel information (VID)
2.Video Clock, pixel clock, or dot clock (VCLK)
3.Horizontal Sync (HS)
4.Vertical Sync (VS)
EL Technology
The display consists of an electroluminescent glass panel and two mounted circuit boards 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 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’s are connected to the EL glass panel with soldered lead frames. The result is a flat, compact, reliable and rugged display device.
