LVDS Connectors: LVDS1 and LVDS2

The EITX-3000 supports two 24-bit single channel LVDS interface

connectors by two D-Sub 26-pin connectors as “LVDS1” and

“LVDS2” on rear I/O coastline, both connectors also carry the

inverter control signals, and can direct connect to two of LVDS

LCD Display via external cables.

Built in LCD Backlight On/Off and Brightness

control signals

Both LVDS1 and LVDS2 connectors all build in the control signals

of “BLON” signal, “BRIGHTNESS_CTL” as well as +12V, +5V and

Ground Pin signals that allow developers/applicants to connect

these signals to LCD Inverter to implement the LCD backlight

On/Off control and brightness control.

• Provides “BLON” signal that inverter Module require for

controlling the Backlight On/Off.

• Provides the 12V, 5V as the Inverter Power Source.

• The “BRIGHTNESS_CTL” signal pin could be connected to LCD’s

Inverter that allow applicant to implement brightness adjustment

through customer’s software utility.
