lvds lcd panel pinout in stock

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.

Dell impression is 14". 14" is 1366x768. You risk get small image at left top coner of LCD 21". LCD 21" is 1920x1080. If MB support resolution 1920x1080 for LVDS - you get good image. I think no. Add LCD-cable (without LCD) to MB and check LVDS resolution 1920x1080.

Also... found and check LCD present signal. I do not found your "present" signal. Present signal usually connected to ground. Usually the cable connected present signal to GND directly.

The notebook MB in some cases not accepted alien displays. LVDS_DDC_CLOCK and LVDS_DDC_DATA signal is EDID. EDID "memory" describe the matrix. May be you need i2c flash rom. May be... connect 3v3,GND,LVDS_DDC_CLOCK,LVDS_DDC_DATA to old circuit of matrix (or path of matrix) of this notebook. If the resolution of screen and resolution of MB is different - you need change flash-bios program. It"s not 100% warranty that all work ok. Good luck.

P.S. I have connected Asus prime h310t to 17" LCD N173GE-L11 directly, I have one power button, and one power supply (12 - 19 v, i7-8700T+mem+MB+tinyHDD+fan+dispay = 1,5A*12v when 0-1% CPU). The thing mini-itx MB may be intrest you.(7-8th gen:GA-IMB370TN, GA-H310TN, Asus prime h310t r20, 10th gen: Asus Pro H410T, GA-IMB410TN - all mb support 1920x1080 1600x900 1366x768 resolution setup from bios). And gigabyte have also simular model.

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.

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.

The pinout, however, has to be determined. I usually take a multimeter, find GND, then VCC, then USB D+ and D- - as the latter are hard to tell apart, I try them in one polarity and swap them if they don"t work.

if you have a piece of this 7" LCD panel, just flip over, you will see this PCB, and you will find the CN1 connector soldered on this PCB so that you can connect the Cable harness from the LCD to the UDOO main board.

I believe this LCD BOARD ADAPTED label "CSA02REVC BD REVC" is NOT made by the LCD panel manufacturer right ? ( that is why it is not in the LCD datasheet )

I am new to this forum and have browsed somewhat through it on this subject, but have not found a solution that helps me, so I thought I"d post. I am an analytical chemist working on a project to design a handheld instrument which contains an embedded CPU board and an LCD panel. The LCD panel we selected for the application has an LVDS interface (24-pins, some of which are for the LED back light). The embedded CPU board we have chosen does not have a native LVDS output (I can get one with the addition of a bulky expansion board), but it does have an HDMI output.

The supplier of the panel provided me with a large (8.5" x 3") board that uses a chip (RTD2662, from RMC) that is used to provide a wide range of video connectors (HDMI, DVI, SVideo) for inputs and it drives the particular panel we have been testing via a custom cable the integrator provided. We were able to drive the panel as a second monitor via the HDMI output of a PC. Thus, I know it can be done.

However, we are very space limited in our design, and this board is much too large for us, and is overkill. I only need one HDMI input and the ouptut to go to the LVDS input of the panel. I am looking for help to understand what this will take.

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.
