1. Internal Frame Buffer This display includes an internal frame buffer The display frame rate and the display brightness are independent of user supplied input data timing The display frame rate can be controlled through the digital dimming feature as described below CAUTION The display includes an internal frame buffer In order to blank the display image in the event of system malfunction pull down the VS signal Dimming There are two standard methods for dimming the EL320 240 36 HB display Analog dimming using the J2 dimming connector described on page 7 of this manual allows for manual dimming from 100 to approximately 5 of the full brightness To perform analog dimming connect a 50 k ohm 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 for maximum dimming from LUMA to GND on the input connector Open circuit voltage is 4 V nominal The internal scan frequency can be controlled via the LUMC and LUMD inputs When LUMC and LUMD are left open the scan rate is determined by the SCAN signal pin 4 on the data input connector With the combination of LUMC and LUMD the following and luminance levels are obtained Table 5 Luminance Control Approx Relative luminance 100 50 LUMD internal pull up Open LUMC internal pull up Open Self Test Mode The display incorporates a self test mode composed o2. 11 ORR RNA N NaS 11 Mechanical Characteristics seen 11 Component nn 11 Description OF Warrant Re un unten 13 Ord ring Information kae a a aa aa RE 13 Support and 5 aa a 14 Figures Figur 1 Data POWer CONNECTION 6 Figure 2 Video Input Timing annee donna 7 Figure 3 Pixel Location versus Sequence of Data 8 Figure 4 Display am te tn 12 Tables Table 1 DC Input Voltage Requirements sense 5 Table 2 Video Input Requirements sen 5 Table 3 J1 Connector Pinouts sn 6 Table 4 Video Input Descriptions 8 Table 5 L minan ce Controle die a a tasses 9 6 tn dede 10 Table 7 Environmental Characteristics sn 10 Table 8 Mechanical Character istics ccscssssssssscscsssssssscsscssssssesssssscssssssesssscsessssesessssessscsesessssesesscsesesseseees 11 EL320 240 36 HB Quarter VGA Display The EL320 240 36 HB thin film electroluminescent EL display is a high performance alternative to quarter VGA LCDs and is the ideal solution in demanding applications where superior visual performance and environmental ruggedness are critical The EL320 240 36 HB utilizes P
