LVDS Flat Panel Connector (LVDS)

7.5
The LVDS connector (Flex boards only) is based on 40 pole connector type Samtec SHF-120-01-F-D-SM-K-
TR or similar.

Note: The LVDS connector supports single and dual channel, 18/24bit SPWG panels up to a resolution of
1600x1200 or 1920x1080 and with limited frame rate up to 1920x1200.
Signal Description – LVDS Flat Panel Connector:
Signal Description
LVDS A0..A3 LVDS A Channel data
LVDS ACLK LVDS A Channel clock
LVDS B0..B3 LVDS B Channel data
LVDS BCLK LVDS B Channel clock
BKLTCTL Backlight control (1), PWM signal to implement voltage in the range 0-3.3V
BKLTEN# Backlight Enable signal (active low) (2)
VDD ENABLE Output Display Enable.
VCC supply to the display. 5V or 3.3V (1A Max.) selected in BIOS setup menu. Power
LCDVCC
sequencing depends on LVDS panel selection. (Shared with eDP connector)
DDC CLK DDC Channel Clock
Notes: Windows API will be available to operate the BKLTCTL signal. Some Inverters have a limited voltage
range 0- 2.5V for this signal: If voltage is > 2.5V the Inverter might latch up. Some Inverters
generates noise on the BKLTCTL signal, causing the LVDS transmission to fail (corrupted picture on
the display). By adding a 1Kohm resistor in series with this signal, mounted at the Inverter end of
the cable kit, the noise is limited and the picture is stable.
If the Backlight Enable is required to be active high then, check the following BIOS Chipset setting:
Backlight Signal Inversion = Enabled.
