LCDs and is the ideal solution in demanding applications where superior visual performance and environmental ruggedness are critical. The EL640.200-SK utilizes Planar’s proprietary Integral Contrast Enhancement (ICE ) technology to achieve unparalleled image quality without the use of expensive filters. This display excels in a wide range of ambient lighting environments while effectively eliminating the blooming common to other high-bright displays.
Excessive cable lengths can pick up unwanted EMI. There are third party products which allow this maximum cable length to be exceeded. Contact Planar Application Engineering for more information. EL640.200-SK Operations Manual (020-0348-00B)
Cleaning As with any glass or coated surface, care should be taken to minimize scratching. Clean the display glass with mild, water-based detergents only. Apply the cleaner sparingly to a soft cloth, then wipe the display. Disposable cleaning cloths are recommended to minimize the risk of inadvertently scratching the display with particles embedded in a re-used cloth.
There is no overcurrent protection on either the V or V L inputs to protect against catastrophic faults. Planar recommends the use of a series fuse on the 12-volt supply (V ). A general guideline is to rate the fuse at 1.8 to 2 times the display maximum current rating.

Connector Video signals and DC power are connected to the display through a 24-contact dual-row 2 mm square pin locking connector, Samtec EHT-112-01-S-D. The mating connector is available through Samtec as an IDC cable assembly (Series TCSD-12-S-XX-01-X-X). The proper connector, user-specified cable length, and connector configuration are supplied as a single unit.
Interface Information This Planar EL display has two types of video interfaces for buffered and non- buffered modes. Changing from buffered to non-buffered mode or vice versa can be done during operation of the display. Pull VIDMODE, pin 18, low for non-buffered mode, and pull it high or leave it disconnected for buffered mode.
Video Input Signals The end of the top line of a frame is marked by VS, vertical sync signal as shown in Figure . The end of each row of data is marked by HS. In non-buffered mode, the VS signal may be independently set to a CMOS low level at any time for longer than one frame period.
Video Data in Non-Buffered Mode In non-buffered mode, input signals VID0 through VID3 and VIDL0 through VIDL3 contain the video data for the screen. Video data for row and row +100 is latched on the falling edge of HS, as shown in Figure 3. Column 1 Column 1 Column 640...
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.
Self-Test Mode The display incorporates a self-test mode composed of a 1 x 2 checkerboard and full-on pattern displayed at 240 Hz. Upon power up, the 1 x 2 pattern is displayed for several seconds, then the full-on pattern is displayed continuously.
Planar reserves the right to relocate components constraints of the component envelope without prior customer notification. For this reason, Planar advises users to design enclosure components to be outside the component envelope. Device designers will need to consider their specific system requirements to determine the spacing necessary to maintain the specified ambient temperature.
EL640.200-SK ALE with conformal coating Design and specifications are subject to change without notice. Planar Systems continues to provide optional, and in many cases custom, features to address the specific customer requirements. Consult Planar Sales for pricing, lead time and minimum quantity requirements.
