LVDS Connector
LVDS1 is the LVDS connector. LVDS (low-voltage differential signaling) is a high-speed
digital interface that operates at low power. It is a type of connection that is used with a
LVDS LCD panel. The connector combines LCD VCC Power (pins 9-10), LVDS high speed
digital interface, backlight power 3.3V (pin 7) and 12V (pins 1-5), backlight enable (pin 15),
and dimming control (pin 13). Select the correct LCD VCC power according to the LCD
specification by JLCDPWR1 (3.3V/5V/12V) before enabling the LVDS panel. Refer to the
tables below for vendor part number, mating, and crimping contact connector information
before making the LVDS/backlight cable.
