You're looking for the pinout datasheet of a 51-pin LVDS (Low-Voltage Differential Signaling) connector. LVDS is a signaling standard used for high-speed data transmission, commonly found in display interfaces, such as LCD monitors, laptops, and automotive displays.
Unfortunately, there isn't a single, universally accepted 51-pin LVDS pinout standard. The pinout can vary depending on the specific application, display type, and manufacturer.
However, I can provide some general information and resources that might help you find the datasheet you're looking for:
To help you find the specific datasheet you're looking for, can you provide more information about your application or the display you're working with? For example:
I'll do my best to help you find the datasheet or guide you through the process of determining the pinout. 51 pin lvds pinout datasheet
The 51-pin LVDS pinout is a standardized high-speed serial interface commonly used in Full HD (1920x1080) and 4K display panels. The most frequent implementation follows the JAE FI-RE51S series connector standard, which utilizes a 2-channel 8-bit configuration. Standard Pinout Configuration (2-Channel 8-Bit)
A typical 51-pin LVDS interface (such as the FI-RE51P) is organized into data signals, clock signals, power, and ground pins. Signal Group Description Data Pairs
12 differential pairs for odd and even pixel data (e.g., RXE0± to RXE3± and RXO0± to RXO3±). Clock Pairs 2 differential pairs for odd and even clock signals. Symmetry/Sync Synchronization signals. Power (VDD) Typically 3.3V power supply for the display panel. Ground (GND)
Distributed throughout the connector for signal integrity and shielding. Technical Specifications You're looking for the pinout datasheet of a

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
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: LVDS pinout standards : There are a few
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.
| Symptom | Probable Cause | Datasheet Solution | | :--- | :--- | :--- | | Screen is white (backlight on) | No LVDS data or wrong SELLVDS pin state. | Check pin 12 (SELLVDS). Verify 3.3V on VDD. | | Image is "snowy" or flickering | Impedance mismatch or clock polarity reversed. | Swap CLK+ and CLK- on the connector. | | Colors are blue/orange swapped | JEIDA vs. SPWG mapping error. | Software register change or swap R/B pins in hardware. | | Backlight won't turn on | BL_EN or PWM voltage incorrect. | Measure BL_EN (must be >2V). Apply 3.3V to PWM for full bright. | | Touch works intermittently | I2C pull-ups missing. | Add external 2.2k to 4.7k resistors on SCL/SDA to 3.3V. |
| Parameter | Value | Note | | :--- | :--- | :--- | | LVDS Voltage | 350 mV differential (100Ω termination) | Each pair must be terminated with 100Ω at the panel side | | Common Mode Voltage | 1.2V | Typically | | Data Rate | Up to 1.2 Gbps per pair | Depends on cable length | | VDD Range | 3.3V, 5.0V, or 12V | Never assume – check panel label | | VDD Current | 500mA – 3A | Larger panels draw more | | Backlight Supply | Often separate 12V-24V on pins 25,51 | Not always present |
| Parameter | Specification | |-----------|----------------| | Pin Count | 51 positions | | Pitch | 0.5 mm | | Mating Type | Compression (zero insertion force – ZIF) | | Locking | Slide lock (front or side actuation) | | Current Rating | 0.5 A per pin | | Voltage Rating | 50 V AC/DC | | Common Mating Cable | FI-X30H (30-pin) – Wait, note: 51-pin housing often only populates 30 or 41 pins depending on display. Full 51 pins are rare. |
⚠️ Important: Many "51-pin LVDS" cables physically have a 51-position housing but only 30 or 41 active pins. Always verify against the LCD panel datasheet.
