LVDS Connector

The Low Voltage Differential Signaling (LVDS) connector at LVDS1 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 +3.3 V (pin 7) and +12 V (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 (short pins 1–3 for +3.3 V, short pins 3–5 for +5 V) before enabling the LVDS panel. To choose the LCD VCC power, short JLCDPWR1 pins 1–3 for +3.3 V or short pins 3–5 for +5 V. Refer to the table below for vendor part number, mating, and crimping contact connector information before making the LVDS/backlight cable.
