51 Pin Lvds Pinout Datasheet (2027)

The 51-pin LVDS (Low-Voltage Differential Signaling) interface is a high-speed serial standard commonly used in Full HD (1080p)

LED/LCD television panels and large industrial monitors. It typically utilizes the JAE FI-R series connector, such as the FI-RE51S-HF 📋 Standard 51-Pin LVDS Pinout Overview

While exact pin assignments can vary by manufacturer (e.g., Samsung vs. LG), most 51-pin configurations follow a dual-channel, 8-bit or 10-bit layout. Easyspares ⚡ Power & Ground LVDS Cable Pinout and Connection Guide | PDF - Scribd

51-pin LVDS (Low-Voltage Differential Signaling) interface is a standard high-speed serial transmission link used primarily in Full HD (FHD) and 4K LCD/LED TV panels. The most widely recognized connector for this pinout is the JAE FI-RE51S-HF JAE 日本航空電子工業 Standard 51-Pin LVDS Pinout Review 51 pin lvds pinout datasheet

While "universal" diagrams exist, the pinout varies significantly between manufacturers (e.g., Samsung vs. LG). Failure to match these can lead to lack of video or permanent hardware damage. AliExpress Common Power Configurations

A critical distinction in 51-pin layouts is the location of the power supply (VCC/VLCD) pins: "Type G" (Samsung/CMO style): Power is typically on Pins 1–4 "Type H" (LG/AUO style): Power is typically on Pins 48–51 Grounding:

Pins located immediately adjacent to power and signal pairs (e.g., Pin 5, Pin 11, Pin 18) are typically connected to GND to reduce electromagnetic interference (EMI). Signal Structure (Dual-Channel 8/10-bit) FI-RE51S-HF - JAE Japan Aviation Electronics Industry, Ltd. Signal Nomenclature Notes

Signal Nomenclature Notes

  • RXO (Odd Channel): Usually corresponds to the primary or odd-pixel data link.
  • RXE (Even Channel): Corresponds to the secondary or even-pixel data link.
  • VCC: Verify the datasheet for the specific LCD panel. Applying 5V to a 3.3V panel will destroy the electronics. Conversely, 3.3V on a 5V panel will result in a blank or flickering display.
  • VLED: High voltage line for the LED driver. This is often 12V or 24V, separate from the logic voltage.

Group 3: LVDS Data Pairs (Dual-Link – 16 pins)

For high-resolution panels (WUXGA, 1080p, 1440p):

  • Link A: TxA0+/-, TxA1+/-, TxA2+/-, TxA3+/-, CLKA+/-
  • Link B: TxB0+/-, TxB1+/-, TxB2+/-, TxB3+/-, CLKB+/-
  • Dual-link effectively doubles the pixel throughput.

2. Core Pinout Logic (Generic LVDS Mapping)

A true 51-pin LVDS connector does not use 51 signal pins. Instead, the pins are allocated across Power, LVDS Data Pairs, Control, and Auxiliary buses.

The table below represents the most widely adopted de facto standard for 51-pin LVDS (used by Sharp, NEC, Mitsubishi, and AU Optronics industrial panels). RXO (Odd Channel): Usually corresponds to the primary

Note: Always verify with the specific panel datasheet; pin 1 location is usually marked with a triangle or dot on the connector body.
