lcd panel connector pinout brands

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.

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.

Elastomeric connectors, also known as ZEBRA strips, are a common connection type for LCDs with surface mount connections. A ZEBRA strip connector is comprised of a malleable insulation strip with alternating conduction lines and can be used as a substitute for a hardwire connection. These connectors get their name from their alternating conduction lines that appear as stripes, similar to a Zebra.

ZEBRA strips are positioned between a display’s connection ports and its controller. They then require a bezel to ensure a proper connection with the display. Once the bezel has been applied, the ZEBRA strips compress against an LCD’s surface mount connection ports. The resulting pressure from the bezel allows for a solid connection between the conductive strips and the display.

This connection type is a good option for testing and prototyping displays as there is no need to permanently connect pins to the display. ZEBRA strips are also a good option for thin, compact LCD and PCB designs. For example, if limited space is available within the enclosure, a ZEBRA strip can be used as an alternative to metal pins or ZIF connectors. ZEBRA connectors can also often be a cheaper alternative to other connection types.

Flexible printed circuit (FPC) and flexible flat circuit (FFC) cables (hereinafter both interchangeably referred to as “FPC” or “FPC Cable”) are widely used connectors that provide access to the internal circuitry embedded in the display. Such connectors are standard in laptops and mobile phone displays.

The flexibility of an FPC cable is ideal for compact devices. The cable is made of a flat, bendable material that insulates the conductive wire connected to the LCD. The conductive leads to the display are heat sealed between durable insulative strips.

Throughholesarea standard connection type for many displays that offer a connection through small holes on the PCB. This connection type is most common for LCDs that have an external PCB controller circuit mounted to the display, such as most character and segment LCDs. Typically, the PCB will include the required liquid crystal driver, a voltage converting circuit, and backlight control.

Metal pins are a connection type for LCDs that have metal pins already mounted and connected to the display. Metal pins can be connected to the internal display controller or to the COM and Segment lines of an LCD. Typically, this connection type is used for character and segment LCDs.

Metal pins are good for applications that have standard pin mappings so that the display can be plugged into the controlling device. This connection type is less versatile than the previous LCD connection types as the pins are hardwired into place and cannot be moved unless unsoldered. The standard distance between pins is 2.54 mm.

Heat seal connections for LCDs are a reliable connection type utilizing a flexible cable connector that is heated and sealed to a displays’ interface ports. This connection uses a special heat seal paper that is then adhered to the display using a conductive glue and sealed by applying heat.

While FPC cables will degrade or become damaged with continuous bending, a heat seal connector will maintain the performance with continuous bending and will not become damaged.

this is actually a Funai manufactured TV rebranded to Emerson. It will help to see your board itself so that we know which version etc. your board is. Post some good pictures of your board and mark what you are looking at. Use this guide Adding images to an existing question for that. You may also enlighten us what you are trying to fix or accomplish with a pinout. the only thing I can see right now is that you are looking at connector CN201 and CN301

If the motherboard is indeed dead, you can easily remove the connector that you want to salvage by using a product known as "Chip Quik". This is a low-temperature solder alloy that is specifically designed to contaminate the existing solder on the board so as to reduce the melt temperature to a very low value.

Note that you don"t need a hot-air rework station to use this product - a standard soldering iron is all that you need. The contaminated solder remains molten for a very long time and you simply float the connector off the board.

After you have removed the connector that you are salvaging, simply flood the connector pins with regular solder so as to wash off the low-temp alloy. The connector should be completely usable.

The LCD is not what is special. The special part is the black elastomeric connector. They are sometimes used with LCDs, since most of the connections are very low current, a high-quality connection is not necessary.

Pins20 pins for external connectors on desktops, notebooks, graphics cards, monitors, etc. and 30/20 pins for internal connections between graphics engines and built-in flat panels.

This is the pinout for source-side connector, the sink-side connector pinout will have lanes 0–3 reversed in order; i.e., lane 3 will be on pin 1(n) and 3(p) while lane 0 will be on pin 10(n) and 12(p).

The interface uses an LVDS signal protocol that is not compatible with DVI or HDMI. However, dual-mode DisplayPort ports are designed to transmit a single-link DVI or HDMI protocol (TMDS) across the interface through the use of an external passive adapter, enabling compatibility mode and converting the signal from 3.3 to 5 volts. For analog VGA/YPbPr and dual-link DVI, a powered active adapter is required for compatibility and does not rely on dual mode. Active VGA adapters are powered directly by the DisplayPort connector, while active dual-link DVI adapters typically rely on an external power source such as USB.

DisplayPort version 1.2 was introduced on 7 January 2010.Gbit/s in High Bit Rate 2 (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth, such as 3840 × 2160 at 60Hz 10bpc RGB. Other improvements include multiple independent video streams (daisy-chain connection with multiple monitors) called Multi-Stream Transport, facilities for stereoscopic 3D, increased AUX channel bandwidth (from 1Mbit/s to 720Mbit/s), more color spaces including xvYCC, scRGB, and Adobe RGB 1998, and Global Time Code (GTC) for sub 1μs audio/video synchronisation. Also Apple Inc."s Mini DisplayPort connector, which is much smaller and designed for laptop computers and other small devices, is compatible with the new standard.

DisplayPort version 1.2a was released in January 2013Adaptive Sync.AMD"s CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard,

When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.0 can enable such configurations as:

DisplayPort cables and ports may have either a "full-size" connector or a "mini" connector. These connectors differ only in physical shape—the capabilities of DisplayPort are the same regardless of which connector is used. Using a Mini DisplayPort connector does not affect performance or feature support of the connection.

The standard DisplayPort connector (now referred to as a "full-size" connector to distinguish it from the mini connector): §4.1.1 was the sole connector type introduced in DisplayPort1.0. It is a 20-pin single-orientation connector with a friction lock and an optional mechanical latch. The standard DisplayPort receptacle has dimensions of 16.10mm (width) × 4.76mm (height) × 8.88mm (depth).: §4.2.1.7, p201

The Mini DisplayPort connector was developed by Apple for use in their computer products. It was first announced in October 2008 for use in the new MacBooks and Cinema Display. In 2009, VESA adopted it as an official standard, and in 2010 the specification was merged into the main DisplayPort standard with the release of DisplayPort1.2. Apple freely licenses the specification to VESA.

The Mini DisplayPort (mDP) connector is a 20-pin single-orientation connector with a friction lock. Unlike the full-size connector, it does not have an option for a mechanical latch. The mDP receptacle has dimensions of 7.50mm (width) × 4.60mm (height) × 4.99mm (depth).: §2.1.3.6, pp27–31 The mDP pin assignments are the same as the full-size DisplayPort connector.: §2.1.3

Pin 20 on the DisplayPort connector, called DP_PWR, provides 3.3V (±10%) DC power at up to 500mA (minimum power delivery of 1.5W).: §3.2 This power is available from all DisplayPort receptacles, on both source and display devices. DP_PWR is intended to provide power for adapters, amplified cables, and similar devices, so that a separate power cable is not necessary.

To support a particular format, the source and display devices must both support the required transmission mode, and the DisplayPort cable must also be capable of handling the required bandwidth of that transmission mode. (See: Cables and connectors)

Limited adapter speed – Although the pinout and digital signal values transmitted by the DP port are identical to a native DVI/HDMI source, the signals are transmitted at DisplayPort"s native voltage (3.3V) instead of the 5V used by DVI and HDMI. As a result, dual-mode adapters must contain a level-shifter circuit which changes the voltage. The presence of this circuit places a limit on how quickly the adapter can operate, and therefore newer adapters are required for each higher speed added to the standard.

Single-link DVI only – Since DisplayPort dual-mode operates by using the pins of the DisplayPort connector to send DVI/HDMI signals, the 20-pin DisplayPort connector can only produce a single-link DVI signal (which uses 19 pins). A dual-link DVI signal uses 25 pins, and is therefore impossible to transmit natively from a DisplayPort connector through a passive adapter. Dual-link DVI signals can only be produced by converting from native DisplayPort output signals with an active conversion device.

Both HDMI and DisplayPort have published specification for transmitting their signal over the USB-C connector. For more details, see USB-C § Alternate Mode partner specifications and List of devices with video output over USB-C.

Mini DisplayPort (mDP) is a standard announced by Apple in the fourth quarter of 2008. Shortly after announcing Mini DisplayPort, Apple announced that it would license the connector technology with no fee. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification.

Micro DisplayPort would have targeted systems that need ultra-compact connectors, such as phones, tablets and ultra-portable notebook computers. This standard would have been physically smaller than the currently available Mini DisplayPort connectors. The standard was expected to be released by Q2 2014.

Direct Drive Monitor (DDM) 1.0 standard was approved in December 2008. It allows for controller-less monitors where the display panel is directly driven by the DisplayPort signal, although the available resolutions and color depth are limited to two-lane operation.

Embedded DisplayPort (eDP) is a display panel interface standard for portable and embedded devices. It defines the signaling interface between graphics cards and integrated displays. The various revisions of eDP are based on existing DisplayPort standards. However, version numbers between the two standards are not interchangeable. For instance, eDP version 1.4 is based on DisplayPort 1.2, while eDP version 1.4a is based on DisplayPort 1.3. In practice, embedded DisplayPort has displaced LVDS as the predominant panel interface in modern laptops and modern smartphones.

eDP 1.0 was adopted in December 2008.Hz sequential color monitors, and a new display panel control protocol that works through the AUX channel.framebuffer memory in the display panel controller.Version 1.5 was published in October 2021; adds new features and protocols, including enhanced support for Adaptive-Sync, that provide additional power savings and improved gaming and media playback performance.

Internal DisplayPort (iDP) 1.0 was approved in April 2010. The iDP standard defines an internal link between a digital TV system on a chip controller and the display panel"s timing controller. It aims to replace currently used internal FPD-Link lanes with a DisplayPort connection.GHz clock and is nominally rated at 3.24Gbit/s per lane, with up to sixteen lanes in a bank, resulting in a six-fold decrease in wiring requirements over FPD-Link for a 1080p24 signal; other data rates are also possible. iDP was built with simplicity in mind so doesn"t have an AUX channel, content protection, or multiple streams; it does however have frame sequential and line interleaved stereo 3D.

SlimPort, a brand of Analogix products,Mobility DisplayPort, also known as MyDP, which is an industry standard for a mobile audio/video Interface, providing connectivity from mobile devices to external displays and HDTVs. SlimPort implements the transmission of video up to 4K-UltraHD and up to eight channels of audio over the micro-USB connector to an external converter accessory or display device. SlimPort products support seamless connectivity to DisplayPort, HDMI and VGA displays.Google"s Nexus 4 smartphone.LG G series also adopted SlimPort.

On 22 September 2014, VESA published the DisplayPort Alternate Mode on USB Type-C Connector Standard, a specification on how to send DisplayPort signals over the newly released USB-C connector. One, two or all four of the differential pairs that USB uses for the SuperSpeed bus can be configured dynamically to be used for DisplayPort lanes. In the first two cases, the connector still can carry a full SuperSpeed signal; in the latter case, at least a non-SuperSpeed signal is available. The DisplayPort AUX channel is also supported over the two sideband signals over the same connection; furthermore, USB Power Delivery according to the newly expanded USB-PD 2.0 specification is possible at the same time. This makes the Type-C connector a strict superset of the use-cases envisioned for DockPort, SlimPort, Mini and Micro DisplayPort.

Since its introduction in 2006, DisplayPort has gained popularity within the computer industry and is featured on many graphic cards, displays, and notebook computers. Dell was the first company to introduce a consumer product with a DisplayPort connector, the Dell UltraSharp 3008WFP, which was released in January 2008.AMD and Nvidia released products to support the technology. AMD included support in the Radeon HD 3000 series of graphics cards, while Nvidia first introduced support in the GeForce 9 series starting with the GeForce 9600 GT.

Nvidia revealed the GeForce GTX 1080, the world"s first graphics card with DisplayPort 1.4 support on 6 May 2016.Radeon RX 400 Series will support DisplayPort 1.3 HBR and HDR10, dropping the DVI connector(s) in the reference board design.

Dual-link DVI is limited in resolution and speed by the quality and therefore the bandwidth of the DVI cable, the quality of the transmitter, and the quality of the receiver; can only drive one monitor at a time; and cannot send audio data. HDMI 1.3 and 1.4 are limited to effectively 8.16Gbit/s or 340MHz (though actual devices are limited to 225–300MHzVGA connectors have no defined maximum resolution or speed, but their analog nature limits their bandwidth, though can provide long cabling only limited by appropriate shielding.
