CCOMe-C96 board allows to interface to Single/Dual Channel 18-/24-bit displays, using the LVDS
channel coming directly from the COM Express module.
The LVDS interface will be available on a connector type HR A1014WV-S-2x25P or
equivalent (2 x 25p, male, straight, P1, low profile, polarised), with the pin-out shown
in the table on the left.
Mating connector: HR A1014H-2X25P with HR A1014-T female crimp terminals.
Alternative mating connector, MOLEX 501189-5010 with crimp terminals series
501334.
On the same connectors, are also implemented signals for direct driving of display's backlight: voltages
(VDD_BKLT and VDD_LCD) and control signals (LCD enable signal, LCD_VDD_EN, Backlight enable
signal, LCD_BKLTEN, and
LCD_BKLT_AN_CTRL).
When building a cable for connection of LVDS displays, please take care of twist as tight as possible
differential pairs signal wires, in order to reduce EMI interferences. Shielded cables are also
recommended.

Backlight Brightness Control
VDD_LCD: LCD Voltage rail. Its value can be
set to +3.3V_RUN or +5V_RUN by using
dedicated jumper JP13, which is a standard pin
header, P2.54mm, 1x3 pin.
VDD_BKLT: Backlight Voltage rail. Its value can
be set to +5V_RUN or +12V_RUN by using
dedicated jumper JP12, same of JP13.
