Note 1: The KTGM45 onboard LVDS connector supports single and dual channel, 18/24bit SPWG panels up
to the resolution 1600x1200 or 1920x1080 and with limited frame rate some 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 flat panel. This supply includes power-on/off sequencing.
LCDVCC The flat panel supply may be either 5V DC or 3.3V DC depending on the CMOS
configuration. Maximum load is 1A at both voltages.
DDC CLK DDC Channel Clock
Note 1: 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, resulting in making the LVDS transmission failing
(corrupted picture on the display). By adding a 1Kohm resistor in series with this signal, mounted in
the Inverter end of the cable kit, the noise is limited and the picture is stable.
Note 2: If the Backlight Enable is required to be active high then, check the following BIOS Chipset setting:
Backlight Signal Inversion = Enabled.
