Introduction
About ELI (the Easy LCD Interface)
ELI®is Future Designs, Inc.’s family of long-life, plug-and-play embedded displays. ELI
products are true modular embedded display solutions that require no engineering or lead-time.
All ELI products are compatible with a wide range of single board computers including
Raspberry Pi, BeagleBone Black and Windows-based units. FDI designed ELI as an embedded
display option that requires minimal development time to help customers reach production
quickly. Once a product is in production, FDI’s 10-15 year ELI product availability guarantee
helps ensure production schedules without the risk of expensive or time consuming redesigns.
Learn more about ELI at TeamFDI.com/ELI.
ELI Compatibility
ELI products are compatible with most single board computers, PCs and operating
systems. See https://www.teamfdi.com/product-details/eli43-cr#compatibility for the results of
FDI’s compatibility tests with popular operating systems and platforms. Our results, as
indicated in the table, demonstrate ELI’s versatility but the table is not exhaustive. ELI
products are designed to work with any single board computer that has an HDMI or DVI
output. To submit a question about ELI’s compatibility with a platform or operating system that
is not included in the table, contact a member of the FDI support team at
[email protected].

ESD Warning
Figure 1. Electrostatic Sensitive Device
Our ELI units are shipped in a protective anti-static package. Do not subject the module to
high electrostatic potentials. Exposure to high electrostatic potentials may cause damage to the
boards that will not be covered under warranty. General practice for working with static sensitive
devices should be followed when working with this device.
Determining the Revision of your ELI
All ELI units have a label on the board to identify the part number and revision. An example of an
ELI label is shown below.

Connectors
Figure 2. ELI43-CR Connectors
Power Details
A 12VDC (+/- 5%) power supply with a 2.0A output will power any board from the ELI Family. This
allows a common, off-the-shelf power supply such as the T1071-P5P-ND to be used for quick demos
or prototyping across the entire ELI Family. In general, any 12VDC power supply with a 2.1mm
center positive plug will be acceptable if it can provide enough current to power the particular ELI
unit being used.
For volume production applications, the input power can be optimized for your particular ELI unit
and lower capacity power supplies can be used.
On the ELI43-CR, plug power into the (P2) connector. In cases where the barrel connector is not
desired, you can use the alternate power input connector (J8) with supports directly plugging in 20-26
AWG wire with maximum 5A current per contact. The datasheet for this J8 connector (PCB terminal
block - PTSM 0,5/ 2-2,5-H SMD WH R24 –1814634) can be found at http://tinyurl.com/1814634.
On ELI43-CR units of Revision ≥3.0 and above, the input power range is expanded from +5 to 24V
DC ± 5% (2.0A) for greater design flexibility.

To verify that the ELI43-CR unit is correctly powered you may check the 12VDC input with a Fluke
meter or scope by probing the +12V and GND contacts, shown below. Please verify that the +12VDC
is present, is within the +/- 5% tolerance and is free from excessive noise or AC ripple.
Note: If using an input that is within the acceptable range of Rev 3.0 ELI43-CR boards, +5VDC
to +24VDC (+/- 5%), please keep in mind that the 12V Test points should be at the voltage of
your chosen power supply (5-24VDC).

Extended Display Information Data (EDID)
ELI uses Extended Display Identification Data (EDID) for automatic configuration with many
operating systems. You can find out more on our website at http://www.teamfdi.com/edid/.

PWM Control of Backlight
Figure 4. PWM Backlight Control
J5 mating connector housing information:
•Manufacturer: Hirose
•Part Number: DF12-3S-1.25C
•Digi-Key Link: https://www.digikey.com/products/en?keywords=H2180-ND
•Pre-terminated wires https://www.digikey.com/products/en?PPV=1811-9-566967
ELI provides an input so an external processor can control the display backlight to vary the display
brightness or to reduce power consumption (the display backlight is typically one of the larger
sources of power consumption in the system). PWM dimming is an input with a 0 to 3.3 VDC range
and the user should drive this with a push-pull type output or a suitable open collector output.
To control the display backlight the user should connect an externally generated Pulse Width
Modulated (PWM) signal to J5 pin 2 with a common ground to J5 pin 3. The frequency range for this
signal is from 5KHz to 100KHz. Each ELI unit’s unique sized display backlight properties will vary,
so the user should test their version for an acceptable range of brightness control. For example, the
actual display 0 to 100% brightness range may be 40% to 90% of the PWM range. In certain
installations, a series resistor may be required to ensure a clean PWM signal is provided to the ELI.
The suggested value for the resistor is 100ohms. See Figure 6 below, for example of connectivity.
Actual testing in your installation may require this resistor to be changed, or possibly not required at
all.
On the ELI unit, the PWM dimming signal is pulled up to LCD_VDD providing 100% backlight
power when no PWM signal is applied at pin 2 of J5. If nothing is connected to J5 the ELI will drive
the display at 100% brightness (default).

The LCD_VDD output at pin 1 of J5 is a 3.3VDC ± 5%. ELI provides the 3.3 VDC signal, called
LCD_VDD, for the external system in case this voltage is needed to generate the correct levels on the
PWM Dimming Input. If the external system is capable of directly driving the PWM dimming signal
at 3.3VDC, there is no need to connect pin 1 to the cable.

Figure 6. Raspberry Pi Signal and Ground
The ELI backlight can be controlled from a Raspberry Pi. See Figure 6 for a wiring diagram. Our software
is available on the FDI website at https://www.teamfdi.com/product-details/eli43-cr#software or you may
copy the code from here:
/* Changes brightness of ELI backlight given a
command line argument between 0 and the set
range. Uses bcm2835 header file provided by
Broadcom at
http://www.airspayce.com/mikem/bcm2835/bcm2835-
1.52.tar.gz This source code must be compiled using
"g++ brightness.cpp -o brightness -l bcm2835"in
order to properly link the header file. Must be
run using sudo, accessing GPIO pins requires root
permissions. After compiling, you may add
executable to "/usr/bin" which allows you to type
"sudo brightness <value>" to change brightness
anywhere in terminal. The "/boot/config.txt" file
must also be changed by adding a "#" before the
line "dtparam=audio=on". This disables audio
output from the Raspberry Pi. If this is not
disabled then anytime sound is output the screen
will return to 100% brightness.

Mechanical View
●Tape used to secure the LCD to the PCB is: 3M VHB 4956 ½” width
●4 screw holes on the ELI43-CR accept up to #4 size screws to mount ELI43-CR into an enclosure
and to connect to the system ground.
●The exposed ground pads may be used to connect the ELI43-CR PCB directly to the LCD using
copper or aluminum foil tape. This practice meets ESD requirements.
