It is possible to purchase the CQ7-D59 carrier board with two alternative configurations, with
CN16
referral to the embedded LCD displays options.
Signal
The first option includes a unique internal connector for LVDS connections. This allows the
VDD_LCD
connection of displays with a colour depth of 18 or 24 bit, single or dual channel.
VDD_LCD
Please notice that the effective support of this kind of displays depends only by the Qseven
VDD_LCD
module used with the carrier board, it is not a feature dependent from the carrier board itself. The
pin-out of this connector is given according to Qseven
3.3V_RUN
ready for the use of any Qseven

CPU module's User manual for the details regarding the panels supported and the availability of
LVDS_A1+/eDP0_TX1+

LVDS_A1-/eDP0_TX1-
For the connection, 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.
LVDS_A3+/eDP0_TX3+
LVDS_A3-/eDP0_TX3-
Mating connector: HR A1014H-2X25P with HR A1014-T female crimp
terminals.

LVDS_B0+/eDP1_TX0+ Alternative mating connector, MOLEX 501189-5010 with crimp terminals series 501334.
LVDS_B0-/eDP1_TX0-
On the same connector, are also implemented voltage rails that can be used to supply the
Backlight Unit and related LCD and signals for direct driving of display's backlight: voltages

(VDD_BKLT and VDD_LCD) and control signals (LCD enable signal, LVDS_PANEL_EN, Backlight

When building a cable for connection of LVDS displays, please take care of twist as tight as
LVDS_B_CLK+/eDP1_AUX+
possible differential pairs' signal wires, in order to reduce EMI interferences. Shielded cables are
also recommended.
