Serial Peripheral Interface (SPI) is a synchronous serial communication interface best-suited for short distances. It was developed by Motorola for components to share data such as flash memory, sensors, Real-Time Clocks, analog-to-digital converters, and more. Because there is no protocol overhead, the transmission runs at relatively high speeds. SPI runs on one master (the side that generates the clock) with one or more slaves, usually the devices outside the central processor. One drawback of SPI is the number of pins required between devices. Each slave added to the master/slave system needs an additional chip select I/O pin on the master. SPI is a great option for small, low-resolution displays including PMOLEDs and smaller LCDs.

Philips Semiconductors invented I2C (Inter-integrated Circuit) or I-squared-C in 1982. It utilizes a multi-master, multi-slave, single-ended, serial computer bus system. Engineers developed I2C for simple peripherals on PCs, like keyboards and mice to then later apply it to displays. Like SPI, it only works for short distances within a device and uses an asynchronous serial port. What sets I2C apart from SPI is that it can support up to 1008 slaves and only requires two wires, serial clock (SCL), and serial data (SDA). Like SPI, I2C also works well with PMOLEDs and smaller LCDs. Many display systems transfer the touch sensor data through I2C.

Low-Voltage Differential Signaling (LVDS) was developed in 1994 and is a popular choice for large LCDs and peripherals in need of high bandwidth, like high-definition graphics and fast frame rates. It is a great solution because of its high speed of data transmission while using low voltage. Two wires carry the signal,  with one wire carrying the exact inverse of its companion. The electric field generated by one wire is neatly concealed by the other, creating much less interference to nearby wireless systems. At the receiver end, a circuit reads the difference (hence the "differential" in the name) in voltage between the wires. As a result, this scheme doesn’t generate noise or gets its signals scrambled by external noise. The interface consists of four, six, or eight pairs of wires, plus a pair carrying the clock and some ground wires. 24-bit color information at the transmitter end is converted to serial information, transmitted quickly over these pairs of cables, then converted back to 24-bit parallel in the receiver, resulting in an interface that is very fast to handle large displays and is very immune to interference.

Mobile Industry Processor Interface (MIPI) is a newer technology that is managed by the MIPI Alliance and has become a popular choice among wearable and mobile developers. MIPI uses similar differential signaling to LVDS by using a clock pair and one to eight pairs of data called lanes. MIPI supports a complex protocol that allows high speed and low power modes, as well as the ability to read data back from the display at lower rates. There are several versions of MIPI for different applications, MIPI DSI being the one for displays.

Low-Voltage Differential Signaling (LVDS) cables typically connect a flat panel display to its control board. While some panel and board combinations may work with a stock cable often a custom cable is needed. This is because each flat panel and control board has a unique pinout and connector required to mate with it. Our engineers will work with you to design your custom cable, to determine the connectors needed, the pinout required to properly connect the components, and any other items that may be needed such as EMI protection and shielding, etc.

Low Voltage Differential Signaling (LVDS) cables with twisted pairs. LVDS cables are custom made to interface between your LCD and Control/SBC or Embedded Mother Board. Shielding options available. Lengths vary from 3.00 inches, to as long as 15.00 feet. Fully Customized to meet your exact needs.

With all of the different LCD panel makers, board makers, Inverter and LED Driver makers out there, the endless variety of components and peripherals yield almost endless connector and pin mapping configurations. Our expertise that has made us an industry pioneer is connecting all of these various devices together with quality products. There are thousands of different connectors that appear on these difference devices. Finding a cable house that is tooled for all of these different parts is hard enough. Finding one with the experience and know how to design, scramble pin maps, maintain differential impedance, shield products to mitigate EMI, all while knowing what hidden aspects of the cable design to look for is our business. With well over 10,000 unique designs on file, all with unique bill of materials, and customized to each customers requirements, our experience helps to assist our customers on all levels of the cable design, and subsequent product support thereafter.

In some cases LCD panels will only have (1) connector on them which contains both data and backlight signals. This cable generally yields a "Y" or "V" shaped cable. This is because the SBC (single board computer), Controller or Embedded Motherboard generally has seperate DATA and BACKLIGHT connectors. Is you LCD panel 18bit or 24bit? PWM or Analog dimming? Do you know what screen orientation you need? Is your panel Dual, Single or even Quad Channel LVDS? All of these factors and many more yield the final cable design. This is where we come in. With over 10,000 unique cable designs that we can produce at an time we have the experience to help offer guidance and expertise where needed.

Most laptop LVDS displays have at least kinda-weird connectors. I don"t support Panelook, and actively avoid that site -- it"s got a paywall between users and documentation, and I refuse to support such a thing in absolutely all cases.

...you will get a number of links of various sorts. Look *specifically* for links that have a little [PDF] icon next to them, i.e., the acronym "PDF" in a (very!) thin outline of a box. If the entire first page doesn"t have anything for you, look for results from eg datasheetspdf.com datasheet4u.com datasheetarchive.com etc. Datasheet Archive (the last one) is actually my favorite. *Absolutely avoid* Panelook if you"re at all like me, but also twscreen.com hkinventory.com etc -- those are sales sites and you"ll never ever *ever* get a PDF out of them so long as you live. Also avoid lcds-center.com lcds-display.com lcds-source.com etc -- these are particularly egregious, because they"ll return [PDF] results, but the PDFs are generated when you click the link and are in fact sales info only -- nothing actually useful in the sense of a technical document, and nothing that gives you even the faintest glimmer of hope of a way to get one. Screw "em.

LVDS1 is mapped to the corresponding device driver in Linux, depending on the ldb peripheral configuration in the device tree. The default value is disabled but can be mapped to /dev/fb2 (second and independent LCD panel) or can be the second LVDS channel for a dual-channel LCD panel configuration (like a 1920x1080 DUAL LVDS channel LCD panel)

There are two more pins to deliver higher current on the rail VIN_LCD. These two pins can be instead separately routed to the expansion connector J40.
