EL320.240-FA3 Multi-Color QVGA Display The EL320.240-FA3 thin film electrolumines cent (EL) multi-color display is a high-performance alternative to QVGA (320 x 240) LCDs and is the ideal solution in demanding applications wh ere superior visual performance, extreme temperature range, and envi ronmental ruggedness are critical. The EL320.240-FA3 ut[...]

EL320.240-FA3 Operations Manual Page 5 of 25 Installation and Set-up Do not drop, bend, or flex the display. Do not allow objects to strike the surface of the display. CAUTION: The display uses CMOS and devices. These components are electrostatic-sensitive. Unpack, assemb le, and examine this assembly in a static-controlled area only. When shi ppin[...]

EL320.240-FA3 Operations Manual Page 6 of 25 Avoiding Image Burn-In As with other light emitting displays, displaying fixed patterns on the screen may cause burn-in, where luminance variat ions can be noticed after hundreds of hours of operation. To avoid imag e burn-in, use a screen saver or use periodic image inversion if possible. No te that the[...]

EL320.240-FA3 Operations Manual Page 7 of 25 Another option is to electrically “OR” the 3 red MSBs together and route the result to R1, OR the 3 red LSBs together and route to R0, and do the same for G1 and G0. Additionally the bits of bl ue could be OR’d together with either the red or green bits depending on the ch aracteristics of the imag[...]

Power The supply voltage and power requirements are shown in the table below. The power will vary greatly depending on th e number of pixels lit and depending on the chosen luminance level (see graph be low.) Power levels will vary up to +/-15 % from display to display due to brightness variation. DC Input Voltage and Power Requirements Parameter M[...]

EL320.240-FA3 Operations Manual Page 11 of 25 Display Interface The display supports five video interfac e modes: SGD timing as used on the Planar EL320.240.36-HB (though with video data differences to denote colors) and the four AMLCD timing modes used on Sharp and Kyocera QVGA color displays (though using only two bits of red and green data). Fou[...]

Connector The display uses the Samtec EHT-110- 01-S-D or equivalent 2mm locking connector. The mating connector is in th e Samtec TCSD family of cable strips. The proper connector, user-specified cable length and connector configuration is supplied as a single un it. Consult your Samtec representative (1-800-SAMTEC9) for the cable/connector options[...]
