EL640.480-AG1 Series VGA Display The EL640.480-AG1 series displays are 8.1" diagonal VGA products which offer designers an affordable solution in demanding applications where superior visual performance and environmental ruggedness are critical. Utilizing Planar’s proprietary ICEBrite (Integrated Contrast and Brightness Enhancement) technology, these displays excel in ambient light environments ranging from dark to nearly sunlight-bright.
Installation and Handling The mechanical package consists of the display panel and electronic circuit board adhesively bonded together and mounted in a plastic bezel. The bezel supplies the mounting ears and protects otherwise exposed leads. The display is made of glass material and must be handled with care.
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. Avoiding Burn-In As with other light-emitting displays, use a screen saver or image inversion technique to avoid causing burn-in on the display.
There is no overcurrent protection on either the V H or V L inputs to protect against catastrophic faults. Planar recommends the use of a series fuse on the 12 volt supply. A general guideline is to rate the fuse at 1.8 to 2 times the display maximum current rating.
Data and Power Connector The EL640.480-AG1 display uses the Samtec STMM-110-01-T-D and the EL640.480-AG1 ET display uses the Samtec EHT-110-01-S-D or equivalent locking connectors. Although these connectors differ slightly, their pinouts are identical and are shown in the table below. The mating connector for both displays is in the Samtec TCSD family of cable strips.
Locking Power and Data Connector The display may be ordered with an optional 20 Pin 2 pin, 2 mm through-hole locking male header, Samtec EHT-110-01-S-D or equivalent. This locking connector is standard on the EL640.480-AG1 ET display. The mating Pin 1 connector is in the Samtec TCSD family of cable strips.
PC104, ISA, and many other interfaces. Planar Application Note 116 summarizes some of the interfacing options that have been used in the past with EL VGA displays.

Self-Test Mode The EL640.480-AG1 display incorporates a self-test mode composed of a 1x2 checkerboard pattern that inverts every few seconds. The self-test mode is entered by applying power to the display with the S signal static.
250 µA (for maximum dimming) from pin 1 to pin 2 of the dimming port. For more information on frame rate dimming please see Planar Application Note 120. EL640.480 AG1 Series User’s Manual (020-0350-00B)
Careful testing is necessary to select appropriate grayscales for an application, especially when the ICEBrite displays are driven at less than their maximum frame rate. For additional information, refer to Planar Application Note 119 or contact Planar's Application Engineers. Environmental Table 8.
Height .197 (0.007) Component Envelope Figures 5 illustrates the distance components extend behind the display. Tall components do not necessarily fill this area. Planar reserves the right to relocate components within the 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.
Tolerances, unless otherwise stated, ± 0.2 mm. Connector is shown from the back side. Figure 5. EL640.480 AG1 Dimensions. Note: This is not a controlled version of the mechanical drawing.
