Dimming 

There are two standard methods for dimming the EL640.200-SK display. To 
perform analog dimming in either buffered or non-buffered mode, connect a 
100 K 

:

 variable resistor between LUMA and GND. Alternatively, an external 

voltage or current mode D/A converter may be used to facilitate dimming by 
sinking a maximum of 250 µA nominal (for maximum dimming) from LUMA to 
GND on the input connector. Open circuit voltage is 5 V nominal. 
To perform digital dimming in buffered mode, the internal scan frequency is 
controlled via the LUM1 and LUM0 inputs. When these inputs are left open, 
the display is scanned at 240 Hz—the maximum scan rate. With the 
combination of the two inputs, LUM1 and LUM0, the following scan 
frequencies are obtained:

Analog Luminance Control 

Luminance control circuitry is provided to allow the user to adjust the 
luminance from 5 to 100 percent of the maximum. Connecting a 100 K 

:

 

variable resistor between LUMA and GND will give a brightness range from 
approximately 5 to 100 percent of the full luminance value. Alternatively, an 
external voltage or current mode D/A converter may be used to facilitate 
dimming by sinking a maximum of 250 µA (for maximum dimming) from 
LUMA to GND on the input connector.
