Before diving into the pinout, let's quickly review what LVDS is:
When drafting PCBs or designing converter boards for a 51-pin interface, strict adherence to LVDS electrical characteristics is required. Differential Voltage Output ( VODcap V sub cap O cap D end-sub 51 pin lvds pinout datasheet
A connector is primarily used in Full HD (1080p) LED and LCD TV panels, particularly those from manufacturers like Samsung and LG . Unlike standard 30-pin connectors, the 51-pin interface supports dual-channel 10-bit data transmission, allowing it to handle higher resolutions and a larger color gamut (up to 1.07 billion colors). Typical 51-Pin LVDS Pinout Layout
Below is a typical reference datasheet layout for a type connector: Pin Number Signal Name Description 1 No Connection 2 - 3 ID_VCC / Reserved Panel Electronic ID Power / Reserved 4 No Connection 5 I2C Clock Control Line (EDID) 6 I2C Data Control Line (EDID) 7 No Connection 8 Odd Pixel Data Channel 0 (Negative) 9 Odd Pixel Data Channel 0 (Positive) 10 Odd Pixel Data Channel 1 (Negative) 11 Odd Pixel Data Channel 1 (Positive) 12 Odd Pixel Data Channel 2 (Negative) 13 Odd Pixel Data Channel 2 (Positive) 14 15 Odd Pixel Clock Channel (Negative) 16 Odd Pixel Clock Channel (Positive) 17 18 Odd Pixel Data Channel 3 (Negative) - Used for 8-bit/10-bit 19 Odd Pixel Data Channel 3 (Positive) - Used for 8-bit/10-bit 20 Even Pixel Data Channel 0 (Negative) 21 Even Pixel Data Channel 0 (Positive) 22 Even Pixel Data Channel 1 (Negative) 23 Even Pixel Data Channel 1 (Positive) 24 Even Pixel Data Channel 2 (Negative) 25 Even Pixel Data Channel 2 (Positive) 26 27 Even Pixel Clock Channel (Negative) 28 Even Pixel Clock Channel (Positive) 29 30 Even Pixel Data Channel 3 (Negative) 31 Even Pixel Data Channel 3 (Positive) 32 - 33 No Connection 34 35 Automatic Gain Control (Optional) 36 NC / Format JEIDA / VESA Data Format Selection 37 Write Protect for EDID 38 - 43 Shielding Ground / System Ground 44 No Connection 45 - 47 System Ground 48 - 51 Power Supply Input (+12V or +5V Typical) Decoding the Signal Clusters
A typical datasheet divides these 51 pins into several functional groups: 1. Power Supply (VCC / VDD) What they do: Provide operational power to the LCD logic board (T-CON). Where to find them: *Note: "NC" pins for single-channel display
Low-Voltage Differential Signaling (LVDS) is the industry standard for transmitting high-speed digital data between graphics processing units and LCD display panels. Among the various configurations, the 51-pin LVDS interface is widely utilized in large-format displays, high-definition televisions (HDTVs), and industrial monitors.
51-pin LVDS (Low Voltage Differential Signaling) connector is a high-density interface commonly used in large Full HD (FHD) and 4K LCD/LED television panels. Unlike the standard 30-pin cables found in laptops, the 51-pin configuration typically supports dual-channel 8-bit or 10-bit data transmission , allowing for higher resolutions and refresh rates. www.bulcomp-eng.com Common 51-Pin LVDS Pinout Layout
While specific manufacturers like or LG may have slight variations, a typical 51-pin datasheet for a 4K panel generally follows this functional grouping: DS90LV047A 3-V LVDS Quad CMOS Differential Line Driver Differential Voltage Output ( VODcap V sub cap
The Display Data Channel (DDC) utilizes the SCL and SDA pins. These pins allow the mainboard graphics processor to read the panel's internal EEPROM (EDID). The EDID contains critical timing data, native resolution variables, and refresh rate limitations. LVDS Differential Signaling Pairs (Pins 12–41)
Commonly supports 2-Channel LVDS (supporting resolution up to 1920 × 1200 or higher).
For more precise information, it is recommended to search for the specific model number of your display panel to find its dedicated datasheet .
Manufacturer Websites (Samsung, LG, AUO): Often provide the most accurate technical documentation.
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
