laptop lcd panel 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.

Buying a replacement laptop screen can be easy if you find a skilled supplier and take the time to read the information provided on the LCD supplier"s website. In more recent years, laptop screen manufacturers have started supplying identical screens that have connectors in different positions. This of course can cause a problem for you if you do not understand screen connector positioning.

On the back of your laptop screen there will be a connector, often referred to as a 20 PIN, 30 PIN or 40 PIN connector. The connector is for the picture signal that comes from the base of the laptop. A flat grey cable will come from the base of the laptop and connect to the connector on the back of the laptop screen. The cable from the base of the laptop can come from either the left or right hand sides (when looking from the back) of the base and therefore you can have the same screen with either a left side or right side connector.

In fact the very same model of laptop can come fitted with screens with left and right connectors, depending on the cables used at the time of manufacture by the laptop maker. In addition to this, we advise that you check the connector position with the screen fitted to the laptop because some manufacturers fit screens upside down which can cause confusion. You want the connector position with the screen in place, from the rear.

Over the years connectors on laptop and tablet screens have changed. Different standards have come and gone and so the sizes and types of connectors vary. Some laptop models can have more than one screen type, especially DELL and Clevo, and some of the older top end Sony machines. Typical connector size are 20 pins, 30 pins and 40 pins although some specialist screens have come with 50 pin connectors. There is also an Acer model with a 34 pin connector screen made by Lucom.

Usually, contrary to popular belief it isn"t to make our lives difficult. Usually cost saving measures are the cause of this as many 15.6" bottom left hand connector screens are in fact technically top right hand side screens, fitted upside down. With a screen fitted upside down, the connector is now at the bottom and far less cable is required from the base of the laptop to the screen connector.

Availability can also be an issue as screen models become obsolete or unavailable manufacturers are forced to buy alternate screens for their laptops and change the LCD cable to match. This can cause the same model of laptop to have different screens that are not compatible due to connector positioning.

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.

It is possible to replace a LCD with another model and it shouldn"t cause long-term issue. I"ve been replacing panels by random eBay or "local Craigslist" ones, or swapping from other laptops for a long time, and if it works then there"s no reason for it to fail because it"s not the original one.

� Dimensions: obviously if you want it to fit correctly you have to chose the same diagonal size, this is often given directly in the model number (eg. LTN156AT32 is a 15.6" LCD). But you also have to look at the actual outer height and width for it to fit perfectly (it"s rare but sometimes you have a few mm difference and it won"t fit). Also, in some rare cases the thickness can matter too.

� Mountings: if it"s a "slim" panel (no metal case all around the panel, circuit board on the bottom protected by black tape), you can have a variety of mounting tabs (none at all, on the side, top/bottom�). If it"s a "standard" panel (with metal case all around), you either screw the hinges directly or there are screwable tabs, the screw position should be the same on all panels.

� Channels: 1, 2, 4 channels� linked to the definition, the higher the definition the higher the number of channels required. A 1-channel panel on a 2-channel motherboard should work, but not the opposite. With LVDS, if you use 2-channels panel on 1-channel board, typically the odd columns will be gray. Sometimes you can swap a 1-channel panel to a 2-channel panel (to get higher definition) because the laptop is actually designed to take the 2 definition. The 2nd channel needs to be enabled and routed to the LVDS connector, and the cable has to have the required wires (some rare laptops have 2 different cables for the 2 different definitions available).

� Bit depth: 6-bit (262k colors) or 8-bit (16.7M colors), rarely matters, on laptops you can typically exchange between the 2. It"s relevant on desktop monitors where the panel configuration is programmed statically in the scaler, if you use the wrong type you"ll have scrambled image.

� Connector pinout: pinout is standard, if you match the protocol and the connector type you should have the same pinout. One exception though, the large pitch LVDS on desktop panels has the pinout reversed compared to laptop panels, if you pick the wrong one (desktop panels usually don"t fit in laptop but you never know) you can indeed fry the board.

� Connector placement: typically CCFL panels have the connector on top and LED panels have the connector on the bottom. Horizontal positioning can vary so always compare with a picture. Some laptops that are sold with different panel have different cables depending on the connector position.

CCFL: not used anymore on 2009+ laptops, some desktop monitors used it for a bit longer. Typically the connector is always the same on laptop, on desktop monitors you have a 2 pins (same as on laptop) and a 3 pins (middle pin is not connected). You can also have more than one tube on larger panels.

LED: with integrated backlight driver or external backlight driver. Most laptops use panel with integrated backlight driver, they send the 19V directly to the display. Most desktops have the backlight driver on the mainboard or the power supply board.

� Panel orientation: this is a bit of an odd one and never seen it on laptop, but I had the case of a desktop panel that was addressed "upside-down". No way to know it beforehand, and the original panel was not available, so I rotated the display in Windows, not very good as BIOS was still showing upside-down�

� EDID whitelist: some rare laptops may have a whitelist for panels. Seen that only on a couple of older ones with LVDS, in that case you have to use a panel with very close characteristics (definition, bit depth, refresh rate) and swap (or flash) the EDID ROM chip; it"s a 24-series I2C ROM.

While it"s not a whitelist, some machines may have the EDID panel configuration statically defined in the BIOS, in that case you also have to use a panel with very close characteristics. It"s very rare on laptops, I think some Chromebooks with Coreboot did it� On desktop monitors it"s commonly the case as I said earlier, the panel configuration is in the scaler firmware on the mainboard.

There are certain combination of parameters that are extremely common, the 15.6" LVDS panel with LED backlight (integrated backlight driver), 1366x768 definition, "standard" shape (non-slim), connector on bottom left� This is typically used on your low to mid-range 15" consumer laptop from Acer, Toshiba, HP� 2008 to 2014 or something like that. So yeah, those are easy to find and won"t cause much trouble, there are loads of different models that are compatible.

And now, Apple: as expected, most of this doesn"t apply with Apple panels. You have to use the original panel on Macbooks. Connector and pinout can be proprietary, they use a backlight driver on the mainboard rather than on the panel, panel shape and dimensions aren"t like other laptops, they have an EDID whitelist, and you can"t even use a 2013/2014 Retina panel on a 2015 Retina even though they have the same characteristics because they decided that backlight should be controlled a bit differently� Same for newer iMac. On old iMac like 2006 models you could swap the panel but it was a bit involving: there is an EDID whitelist so you have to swap the ROM, they used a desktop panel for the 17" iMac so pinout is reversed, it"s thicker and has special mountings, and it has 2 CCFL tubes (laptops 17" panels have only one) so you have to connect a dummy tube behind the panel.

Touch panels are another beast, and I haven"t had to replace a fused panel yet but if you do, you have to use the original panel as well (since the digitizer is pretty much designed for a specific model). For non-fused panel (where you can separate LCD from digitizer) then you can use another model if it fits properly.

In which case, replacements can be found on-line. The only thing is to buy a cable that will fit in your laptop. Length does not have to be exact, but its always better to have a longer cable than one that is too short. You can"t cut and splice these effectively, not without good expensive tools anyway..

All modern laptops can connect to an external display, such as an LCD monitor, projector, or TV. The external display can extend your viewing area, giving you more space for applications, or mirror your laptop screen (show the same thing on both screens).

To connect the external display to a laptop, locate the correct port on the body of your laptop. Most laptops utilize on or more of the following connections: HDMI, DisplayPort, DVI, or USB-C (Thunderbolt 3). Some older laptops use VGA. These various connections are shown in the images below.

Once you plug the display into your laptop, you may be required to press one or more keys on the laptop"s keyboard to "activate" the external display. This shortcut key combination varies depending on the laptop, but is often one of the following: hold the Fn key, and then press F3, F4, F5, F7, F8, F9, or F10.

The activation function key usually has a picture of a monitor on or above it. Consult your laptop"s manual if you can"t find the key. If you are still having trouble, or you need to download a copy of the manual, visit the laptop manufacturer"s website.

If your laptop connects to a docking station, there should be several video ports on the back of it for a monitor. However, the types of ports varies from brand to brand. Depending on the docking station, the laptop may have to remain open for a dual monitor display.

In many cases, yes. If only the laptop"s screen is broken, an external monitor usually still works with your laptop. However, if there are other malfunctioning components, such as your video hardware, the external display may not work.

Even if you are extremely careful with your hardware, it can be unavoidable at times to run into issues such as a cracked or broken computer screen. Just because you’re experiencing problems with your display doesn’t mean that your laptop is beyond saving, however.

You should also know that repairing your laptop screen isn’t always the easiest job, and there is a possibility you can make the problem worse while voiding the manufacturer warranty. It’s important to feel confident in your skills before you begin the process of replacing your screen, and to consider if you would be more comfortable taking it in to a qualified repair shop.

Even those who have never replaced a screen can manage to do it depending on the type of computer. Just be aware that if you own a laptop with a touch screen it can make the process much more challenging.

If you’re wondering about broken laptop screen repair costs, you’ll be happy to know it’s not as expensive as you may assume. Professional repair costs are usually around $300 or so [1]. If you are comfortable working on your laptop yourself, you can usually find replacement screens online for reasonable prices - sometimes as low as $50 to $100 - and it often only takes an hour or two to complete the replacement job.

The first step is making sure the device powers up successfully and that the screen is the only issue you need to address. As a test, hook your laptop up to a separate monitor. If your laptop seems to function well, then it’s likely that the broken laptop screen is all you have to worry about. Keep in mind that some laptops need to have some function keys pressed in order for an external display to work properly.

Also, if the frame of your laptop has suffered physical damage, then you may have some difficulty repairing your screen. Once you have looked over your device and determined whether you can fix it on your own, it’s time find the right screen for your computer.

Note: If you’re concerned about your laptop’s touch screen repair, it can be more complicated to fix this problem without professional help. These displays are designed with factors like sensitivity in mind, so it’s a good idea to have an expert take a look at it, even if it means spending a bit more than anticipated.

One of the main reasons you should know the model of your laptop is so you’re sure that you’re purchasing the correct replacement screen. While a number of companies offer laptop screen repair kits that can make the process easier, if you order the wrong screen you won’t be able to make any repairs. If you’re having difficulty figuring out your computer model, you can visit the “Settings” menu and find the serial number to assist you in your search.

Fortunately, finding the right screen for your device doesn’t have to be stressful. Often you can find what you are looking for simply by entering your laptop model number into the search bar of online retailers. You may also want to include the search term “LCD” in order to narrow down the accessories that are available for your computer. For the most part, screens should be priced fairly reasonably and you may even be able to buy some for around $50, although it depends on the type of computer you have.

Some sellers may use another form of identification for the model of your laptop, so double check that you chose the right option before you purchase. Almost all the information you need should be displayed on the seller’s listing. Again, take the time to compare your device’s specs with the screen you’re purchasing, and also make sure that the video cable on the back of your screen matches what the vendor shows online. Most of the time, it’s fairly easy to know if the right screen is available.

Once you have assembled the tools you need to replace the screen, you can get to work repairing your device. Lay the closed laptop on the flat surface you have chosen and keep your tools nearby.

First, turn off your laptop and make sure that it is unplugged from a power source to avoid any risk of electric shock. After that, it also helps to remove the battery to avoid causing any other issues.

It’s now time to gently remove the bezel. Make sure you are careful when removing your old screen’s bezel because you will need to reinstall it once the screen is replaced. By using a putty knife or other flat object, you should be able to pry your screen from your laptop case.

One of the trickier parts of replacing your laptop screen will be removing the LCD. First, make sure that the bezel is completely off so you can have unfettered access to the LCD screen. It will be secured onto the laptop’s metal frame, and you will have to take it off from the left and right sides.

There will be two more screws to loosen at the top corners before you can lift the screen slightly away from the metal frame. You’ll probably find a few more screws securing the LCD on the sides, and these will also need to be unscrewed. In some cases, heavy duty tape may have been used instead.

After you remove the attachments, your screen should now lie on your keyboard. It can be a bit of a challenge to make sure there is enough space between the LCD and the metal frame, but you should be gentle to avoid ruining the video cable that runs from the back of the screen to the body of the laptop. If this is damaged, you will need a professional’s help to repair it.

Now it’s time to disconnect the cable from the LCD. You can usually find the connectors in the center, though they may alternatively be located at the bottom of your screen. It’s likely that adhesive was used to connect the two, so you will need to gently pry one from the other. There may also be some tape that needs to be removed, but overall it should be pretty simple to disconnect your LCD from the video connector. Set it somewhere away from your tools.

As you remove the screen, you should be able to locate where your new one will go. Place it face down within the frame so it fits perfectly. After that, you can reattach the video connector so it is placed exactly where the previous LCD sat. Make sure that it is as aligned as possible then attach it with tape or adhesive.

From there, you should be ready to restart your computer. Put the battery in and connect your laptop to a power source before turning it back on. If there is no display, then you will need to double check that everything was properly put back together.

Repairing a broken laptop screen doesn’t have to be done by a professional. If you have the time and interest, then you can end up saving a lot of money by doing it yourself. By following these DIY steps, you can have your laptop display back up and running in an hour or two.
