lvds lcd panel pinout supplier

This is a page where you can find common laptop/desktop LCD panel pinouts and see if your laptop screen"s pinout matches any one of them (it likely does!).

This is a very common pinout for higher-resolution CCFL displays. If you have a 1440x900, 1400x1050 or 1680x1050 panel, it"s likely using this pinout.

This is a pinout for desktop LCD monitor screens - laptop panels do not use this pinout (if there are some, let me know). If you"re ordering a MT6820 (MT561) board, it will arrive with a cable that has this specific pinout and is therefore incompatible with laptop screens - as you"re likely here to reuse a laptop screen, you will want to either rewire the cable you get, or order a suitable cable (for either A or B pinout, whichever you need) from the beginning.

This is a pinout for older, 1024x768 and similar laptop screens, CCFL-equipped ones. 1024x768 screens used both the A pinout, this pinout and even a different pinout with a connector I haven"t made a description for yet, so if you have a 1024x768 screen you"d like to reuse, there"s three possible options and you need to check which one you have before you buy/reuse/build a cable.

This is a pinout that"s, apparently, specific to a select range of 18.5" 1366x768 displays used in desktop LCD monitors. It"s not compatible with either A, B or C pinouts, and requires a specifically wired cable.

In some datasheets, the pinout will list extra pins - one before and one after the main pins, both would be described something like "shield GND". So, for a FI-X 30-pin connector, you might find a pinout in your datasheet that lists 32 pins instead of 30. These two pins are not "real" connector pins and you shouldn"t worry about them - they"re pins that the manufacturer decided to mention for some reason, but they"re not relevant when you are actually connecting to the panel.

I have heard, though haven"t yet confirmed, that sometimes manufacturers mean different things by "odd" and "even" when it comes to LVDS links. If you connect your display and it works great but has swapped lines, you will likely need to rewire your cable =(

As screen showing text is in black and white mode, it may display well even the interfaces are miss-matched. But not for color, it is highly possible causing by the LVDS interface type matching problem. Please recheck the host interface type and TFT interface type in their specifications.

Since different type of LVDS signal packing the RGB data in different ways, showing a gray level bar on the display will help you see the issue easily. (Please refer to Appendix for possible result)

Yes, it can work. You just need to leave the IN3+ and IN3- opened and connect the others. (Please, refer to their specification for details) As the 18bit-LVDS signal cannot tell the TFT display to show a “full white(FFFFFF)”, the highest white level will be ”FCFCFC”.

Check the backlight power supply. There may be a “low-level” PWMgiven to the TFT display module which dims the backlight brightness . Or the PWM active level is reversed. Also, it could be wrongly feeding a 18bit LVDS data to a 24bit-LVDS(VESA) TFT display module . (see Appendix) Some of Topway"s TFT display modules have interface selection setting. It might be wrongly wired. (Pls, refer to their specification for details)

Understanding how LVDS interface interoperately works with each other will save you a lot of time during implementation. Leave us a message if you need LVDS assistant.

First, let us start with dividing internal and external interfaces in LCD modules. Internal interface of display means it used inside the device. Those are usually the embedded interfaces that are not visible, and we do not have access to them as the users of the device. External interfaces, on the other hand, are connected to the device using a cable. Once we have defined internal and external interfaces, both of these categories come as universal or image transfer interfaces.

These Riverdi products are very advanced Intelligent Displays, made with Bridgetek controllers. The controllers use SPI and QSPI for communication. That means your software, your system, your microcontroller can be simple. You can use SPI interface to drive them, and you can still have high resolution image, even as high as 1280 by 800 pixels in 10.1-inch LCD displays. So, please remember that if you want to use a slow universal interface and have a high-resolution image, you need to use an Intelligent Display.

There are also the internal image transfer interfaces. The image transfer interface allows continuous high speed image transfer. Internal transfer is high enough to refresh the display many times per second. This is called the refresh rate of a display. When you go to a display, monitor, or TV set specification, you will see  refresh rate or maximum refresh rate parameter. If it’s 60 Hertz, that means the display image is refreshed 60 times per second. More advanced displays would have higher values, like 100 Hertz. The refresh rate means we need to send full image 60 times or 100 times in each second. To visualize this amount of data, we need to multiply refresh rate by the resolution of the screen. For example, for a 7-inch Riverdi LVDS display with resolution 1024 by 600 it is roughly 600 thousand pixels.

The most common internal image transfer interface in industrial LCD displays nowadays is LVDS – Low Voltage Differential Signal. A crucial feature of this interface is that it is differential. It means that the signal is immune to interference and we can use a twisted pair of wires to transfer the data. We can send data fast and it will not be corrupt by any noise, interference. This kind of data corruption is quite common in other interfaces.Key Takeaway: In LVDS display interface the differential signal allows you to send the signal at a very high speed and keep it safe from noise.

The next, older image transfer interface is called RGB. Name comes from the colors sent parallelly to the display: red, green and blue. LVDS is a serial interface and the RGB is a parallel interface. The main difference is that RGB is not differential, so it is easier to disturb signal with noise and you configure the speed of this interface too high. Parallel interface means that we send every bit in a separate line. In theory this interface could be fast, but because it is not differential, the transfer speed is limited. Moreover, the RGB display interface will work with rather small screen sizes –  usually up to 7-inch or 10-inch.

12 inch screen size is the total maximum for a LCD display with RGB interface, but the resolution will be lower, like 800 by 600. For this display size it is very low resolution. This is the reason why the 7-inch is size above which the LCD displays are being switched from RGB to LVDS interface. Among Riverdi products (if you go to the Riverdi website and to the IPS display tab), there are displays without the controller, and the small displays like 3.5-inch, 4.3-inch and 5-inch are equipped with RGB interface. But when you go to the 7-inch LCD displays tab on Riverdi website, you will find RGB, LVDS and MIPI displays. But when you go to the 10-inch or bigger displays, you will only find the LVDS displays because our 10-inch LCD displays are high resolution 1280 by 800, and it is impossible to build it with the RGB interface.Key Takeaway: RGB is low speed and not immune to noise. Use it for the smaller size displays or with lower resolution.

Next interface is the Vx1. It is similar to LVDS  and MIPI, so it’s low voltage differential signal. Vx1 is a very high-speed interface, usually used in large high-resolution screens, like 55-inch 4K TVs or even larger ones. If you buy this kind of a TV set right now, probably the embedded interface inside will be the Vx1.Key takeaway: Vx1 is a super-fast interface used for high bandwidth image transfer, with high refresh rate and high-resolution displays, used in 4K screens and above.

The last internal image transfer interface is Embedded DisplayPort (eDP). We call it the new LVDS, because many new industrial displays are equipped with the eDP. If you go through industrial manufacturers of TFT LCD displays, you will notice increasing number of models available with the eDP. eDP is also a native interface in new Intel or AMD based processors.Key Takeaway: With the embedded DisplayPort as a native display interface you can cut down costs, because you do not need anything extra to connect a display to the processor.

Now, with the processors on the market, we need displays with embedded DisplayPort. Many laptops or monitors already use embedded DisplayPort as an internal interface instead of LVDS. LVDS still is the most popular industrial LCD display interface. All the internal image transfer interfaces like MIPI, Vx1 and eDP are variations of LVDS, where the protocols and the signals are a little bit different. For example, for eDP we can have lower noise and reduced power consumption. All of them have advantages over regular LVDS, but they are all LVDS type.

The connector is little bit different in each, but the pinout and everything else stays the same.Key Takeaway: HDMI is an extremely popular and easy to use interface. It can send both multimedia A/V data.

Two common high-speed communication protocols for displays are MIPI DSI and LVDS. The Mobile Industry Processor Interface, also known as MIPI, is a high-speed differential protocol that is commonly used in cellphones. Specifically, the MIPI Display Serial Interface (DSI) technology is designed for display communication. LVDS is a technique that uses differential signaling at low voltages to transmit display data. While LVDS is a broad technical specification for signaling, it has become synonymous in the display industry with the FPD-Link protocol (Flat Panel Display Link). MIPI DSI and FPD-Link are both communication protocols that use LVDS as their standard.

The MIPI DSI was designed to interface display’s for cellphones and smart devices and is the most common connection interface for these devices today. This interface uses LVDS signaling over a D-PHY layer to communicate with the display over two or four data pairs. In addition to the data lines, the MIPI interface has a differential clock pair that times the signals at a high frequency.

These clock and data lanes are triggered at low voltages which make these displays low powered. Because this interface can signal data at a very high speed, a large amount of data can be sent over the minimum frame rate requirements. This means that MIPI interface displays can be high resolution, render high color, and can be used for high-speed applications such as video transmission. Below is an example of a Focus LCDs MIPI interfaced display,. This display is a 4.3” TFT with 480x800 pixels and is connected through a 2-lane MIPI interface. Additional features of this display are reviewed below.

The Flat Panel Display Link interface (FPD-Link) has become synonymous with the LVDS interface in the display industry. The LVDS interface explained in this note will be in reference to the FPD-Link protocol. This protocol was the original high speed display interface that uses differential signaling at very low voltages to transmit data at a high frequency. This interface is most commonly used for connecting laptops and televisions to their graphics controllers. The LVDS interface transmits data over four differential data pairs six or eight bits at a time.

One example of a display that is connected through an LVDS interface is E70RA-HW520-C. This display is a 7.0” TFT with 1024x600 pixels and can display up to 16.7M colors. This display has embedded gate and a source driver IC’s that can be programmed from a standard graphics controller. Below are additional features of this LVDS display.

The display communicates over an LVDS interface to an attached HDMI module, which supports the gate and driver signaling as well as the capacitive touch interface. The LVDS interface of this display accepts RGB data in sequences of six or eight bits corresponding to the 16-bit, 18-bit and 24-bit color depths. This display has four differential data pairs and one differential clock pair.

Similar to the MIPI DSI interface, this protocol is low voltage and uses differential signaling. Additionally, this interface has low EMI noise and has a high frequency. This display operates at a clock frequency of 65MHz for the LVDS interface. The clock frequency is determined by the interface capabilities and the resolution of the display in order to maintain a refresh rate of 60Hz.

Below is a description of each of the pins that you can find on an LVDS interface display. This is a typical pin configuration for an LVDS interface display. It is important to verify that the pin connection matches with the graphics controller before connection because some LVDS displays may have alternative pin mappings and features.

The LVDS interface for displays reduces the pin count of the RGB signals to a few differential pairs. This is beneficial for hardware connection while still maintaining the large amount of data transmitted. The differential signaling also reduces EMI noise because the signals are equal and opposite and cancel out electromagnetic radiation effects. Another benefit for LVDS displays is the standard pinout for the connection cable. This makes these displays accessible to many graphic controllers and predesigned systems.

As technology advances with display communication interfaces, so do the methods of reducing the complexity of the system. MIPI DSI and LVDS have collaborated with VESA (Video Electronics Standards Association) to integrate video compression with their interfaces, which reduces the memory constraint of the display. The display technology itself is low cost, power efficient and high performing. The devices used to communicate with these displays are making progress on reducing cost and increasing availability over time.

LCD panel interfaces have changed over the years as resolutions have moved from 640×480 to 3840×2160. The following outlines the common ones that we support with our LCD controllers and cable kits. They cover most of the large size and higher resolution LCD panels on the market:

LVDS: LVDS was introduced in the late 1990’s and enabled connection for higher resolution panels with the benefit of reducing EMI. The LVDS interface is supported by most Digital View LCD controllers and covers panel resolutions from 640×480 to 3840×2160 though newer formats are replacing it for higher resolutions. It remains very popular for HD type resolutions, ie up to around 1920×1200. Most LCD panel manufacturers have LCD panels supporting LVDS, including AUO, BOE, Innolux, JDI, Kyocera, LG, Mitsubishi, Sharp, Tianma. LVDS is Low Voltage Differential Switching.

V-by-One: Increasingly common on 4K resolution panels typically 55″ and larger though I did find a 32″ 1920×1080 panel and 28″ 3840×2160 panel listed as in production. A benefit of V-by-One compared to LVDS is the reduction in cables for high resolution signal support and reduced EMI. LCD panel brands using V-by-One include AUO, BOE, Innolux, LG, Samsung, Sharp. I thought of V-by-One as replacing LVDS but apparently it was developed to replace FPD-Link.

eDP: First introduced in 2008 it is widely adopted by LCD panels used in laptops and similar devices. We are also now seeing it being used in higher resolution and brightness LCD panels but still typically smaller sizes, ie 30″ or smaller. Digital View LCD controller models supporting eDP include SVX-4096, SVX-2560, SVH-1920v2 and the new DD-1920-HDMI-EDPT. Brands using it include AUO, BOE, Innolux, LG, Panasonic, Samsung, Sharp, Tianma.

TTL: Supported by the ALR-1400v2 and HLR-1400v2 controllers this was the common panel interface when Digital View was founded in 1995. VGA (640×480) to XGA (1024×768) resolutions were mainstream at that time. Still used in commercial and industrial display applications AUO, Innolux, Kyocera, Mitsubishi, Samsung, Sharp, Tianma have LCD panels in production with resolutions such as 640×480, 800×480, 800×600, 1024×768. The name TTL is short for Transistor-Transistor Logic.

FPD-Link: The original low voltage differential switching signal but not to be confused with the LVDS interface on many panels as described above. It is now often used in the automotive market and currently up to FPD-Link III. It is not currently supported by any Digital View’s standard controller models though we are looking at it as a custom development option.
