CD3 Display 1 Product profile The EL640.400-C2, -C3 and -CD3 displays are VGA-compatible high-resolution Thin Film 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 allows addition of features or reduction in overall size.
In the EL640.400-C2, -C3 and -CD3, the 640 column electrodes and 400 row electrodes are arranged in an X-Y formation with the intersecting areas performing as pixels. Voltage is applied to both the correct row electrode and the correct column electrode to cause a lit pixel.
Operation Manual EL640.400-C2, -C3 and - CD3 Display Input to the display Table 1. Input to the display Pins Signal Symbol Description J1(Data/power input connector) 1, 2 Voltage Supply voltage (+11 V …+30 V) converted to required internal high voltages (see J2).
Operation Manual EL640.400-C2, -C3 and - CD3 Display Pins Signal Symbol Description Low Power _LOWPWR The power consumption of the display is lowered to LOW-POWER-OPERATION values if the _LOWPWR is low, internally pulled high if left disconnected. Enable ENABLE The operation of the display unit is disabled if the ENABLE input is low, internally pulled high (enable) if left disconnected.
NOTE: Absolute maximum ratings are those values beyond which damage to the device may occur. The minimum and maximum specifications in this Operations Manual should be met, without exception, to ensure the long-term reliability of the display. Beneq does not recommend operation of the display outside these specifications.
200, 350 and 400 row VGA modes and normal mode is similar to normal mode in most Beneq displays. Timing mode is determined from a combination of the polarities of the VS and HS pulses and the _BLANK signal at the rising edge of the VS pulse and the polarities of VS and HS pulses at the rising edge of the _BLANK pulse.

Operation Manual EL640.400-C2, -C3 and - CD3 Display Display enable The display can be totally shut off for screen saving or power reduction by a LOW sate in the ENABLE control input. When disabled, the display stops scanning and only the DC/DC converter remains functional.
47 could be placed at each of the four signal line outputs of the transmitter in order to lower signal reflections. ELECTROSTATIC CAUTION: Beneq display use CMOS and power MOS-FET devices. These components are electrostatic-sensitive. Unpack, assemble and examine this assembly in a static-controlled area only.

Operation Manual EL640.400-C2, -C3 and - CD3 Display CAUTION: The ambient temperature of the display should not be allowed to exceed the environmental specifications (see Table 10). In most applications, an air gap of approximately 5 mm is recommended (see mechanical drawings). Some applications may require, however, a larger air gap or cooling of the display unit in the system.
