Replacement LCD Screen Display For LPM140M420 14.0 inch WQHD Glossy 500nit Panel
iProGadgets OEM Repair Parts for LPM140M420 14.0 inch WQHD Glossy 500nit Laptop Screen Replacement — Quick Answers
Quick answer: this is a brand-new 14.0 inch WQHD replacement LCD panel — the panel coded LPM140M420, the glossy 500 cd/m² screen at 2560 x 1440 and 60 Hz on a 40-pin eDP connector, covering 100% Adobe RGB, double tested before shipping and covered by a 30-day return window on unused, uninstalled parts. It measures 314.82 x 196.1 mm with no mounting brackets and is supplied as the bare panel — no touch layer, no digitizer, no bezel. Three things decide this order. First, the code: Lenovo list this panel and the B140QAN02.0 panel as alternates for the same display option, so your label may carry either string and both are correct. Second, the surface: these machines also shipped with a 14.0 inch WQHD anti-glare screen at a lower brightness on the same frame, so if the front of your old panel is matte, this glossy panel is not the part. Third, the resolution: the same laptops also shipped with a 14.0 inch Full HD screen on a smaller connector, which this panel will not replace. Send us the code from the label on the back of the screen you are removing and we will confirm exactly which panel we are shipping before dispatch.
- Fit: The 14.0 inch WQHD panel coded LPM140M420 — the glossy 500 cd/m² 40-pin eDP screen with 100% Adobe RGB that sits alongside the B140QAN02.0 panel as an alternate for the ThinkPad X1 Carbon 6th Gen, T490, T490s and P43s WQHD configuration
- Panel: LTPS TFT-LCD IPS panel (normally black, transmissive) with a WLED edge-lit backlight and the LED driver on the panel board, a gloss front with a hard coating, 100% Adobe RGB, 500 cd/m², and no mounting brackets
- Testing: every unit is double tested before shipping — display, and fitment against the machine it is sold for
Technical Specifications
| Item | Detail |
|---|---|
| Panel code — this listing | LPM140M420. Read the code on the label on the back of the screen you are removing and compare it with this one. Some suppliers write the same panel as LPM140M420 A or LP140M420 — the strings differ, the panel does not |
| Service part number | Read your label code and send it to us rather than ordering on the strength of a cross-reference list |
| Screen size | 14.0 inches diagonal (35.6 cm), 16:9 |
| Resolution | 2560 x 1440 px (WQHD), 210 PPI |
| Refresh rate | 60 Hz. One factory record also notes a 48 Hz dynamic refresh mode on this panel; the machines below run it at 60 Hz |
| Panel technology | LTPS TFT-LCD, IPS wide-viewing-angle panel (normally black, transmissive, 88/88/88/88), 16.7M colours, with a WLED edge-lit backlight and the LED driver on the panel board |
| Brightness | 500 cd/m² typical — the high-brightness HDR bin of this display option. These machines were also orderable with an anti-glare WQHD screen specified at 300 cd/m², so a replacement taken from the other bin looks dimmer or brighter than the screen it replaces: that is a production difference between versions, not a fault |
| Colour gamut | 100% Adobe RGB — this panel and the B140QAN02.0 panel are the wide-gamut choice for these machines. The anti-glare WQHD option covers a narrower gamut, so fitting that one into a machine set up for this screen gives visibly flatter colour |
| Surface finish | Glossy (Haze 0%) with a hard coating, consistent across the factory records. If the front of the screen you are removing is matte you need the anti-glare part instead — same frame, same connector, different surface |
| Touch | No — this is the non-touch panel supplied on its own, with no touch layer and no digitizer glass. If the screen you are removing responds to your finger, you need the touch assembly instead and this panel is not it |
| Signal interface | eDP, 4 lanes, 40-pin connector, eDP1.4, 3.3 V logic with the backlight driver fed at 5.5 to 21 V from the panel board — the plug is about 25 mm across. Count the contacts on the flex of your old screen before ordering: a 30-pin Full HD panel is a different part |
| Connector position | Bottom right, viewed from the back of the panel |
| Outline and mounting | 314.82 mm wide x 196.1 mm high x 2.4 mm deep, active area 309.12 x 173.88 mm, slim profile, no screw brackets and no lugs. The alternative panel for this display option measures 315.05 x 195.6 mm — under a millimetre apart, which is why the two are published as alternates, but measure your bezel opening if your machine has been repaired before. We supply the panel on its own, so have fresh adhesive ready before you start |
| Production status | The factory record still shows this panel in production (mass production from the fourth quarter of 2018), unlike the B140QAN02 suffix family, which is discontinued. That makes this the code to ask for when you need a continuing supply rather than a one-off repair |
| NOT the Full HD panel | The same families also shipped with a 14.0 inch Full HD 1920 x 1080 panel on a 30-pin connector. A 30-pin panel and a 40-pin panel are not interchangeable, and a Full HD machine does not drive this WQHD screen correctly. Count the contacts on your old flex before ordering |
| NOT a touch screen and not a whole display assembly | This is the bare non-touch panel — no touch layer, no digitizer, no display bezel, no rear cover, no hinges and no camera module. If you need the complete display assembly or a touch screen, tell us before ordering |
| Condition | Brand-new, unassembled |
| Quality | iProGadgets OEM Quality |
Compatibility
| Device | Model numbers / part codes |
|---|---|
| Panel code covered — this listing | LPM140M420 |
| Machine coverage — supplier data conflicts | Send us the code from your old panel rather than ordering on the strength of a retailer list |
| NOT the Full HD panel | The X1 Carbon and T-series machines also shipped with 14.0 inch Full HD 1920x1080 panels on a 30-pin connector. Different resolution, different pin count, different part — a Full HD machine will not drive this WQHD panel |
| NOT a touch assembly or a full display | This listing is the non-touch screen panel on its own. Touch screens for these machines are separate assemblies with the digitizer built in, and they are not interchangeable with this bare panel |
Before We Ship — Please Send Us These 3 Details
Laptop, all-in-one and desktop PC screens can differ between revisions of the same model, so the listing alone cannot always tell us which panel is inside your machine. After you place the order we will contact you for the three items below — please send them so we can confirm the fitment and ship the correct, fully compatible screen straight away:
- A photo of your computer. A clear photo of the laptop itself, plus the model / service label on the bottom cover (or the model name shown in Settings → About).
- Resolution, surface and pin count. Tell us whether your screen is 2560 x 1440 or 1920 x 1080, whether the front is glossy or matte, and whether it is a touch screen. If you are not sure, send a photo of the front and of the back of the panel and we will read it for you.
- Photos of your old screen. Once the machine is opened, a full photo of the back of the old screen and a close-up of the label or barcode sticker on it. That label carries the exact panel part number, which removes any doubt about which screen you need.
We check your photos against our stock before dispatch. If something does not match, we will contact you first instead of sending a part that may not fit. Once your details are confirmed, we arrange shipment within 1 to 3 business days. Thank you for helping us get it right.
Installation Notes
- Clean the flex cable with alcohol before installation and confirm that it is well connected.
- Do not pull, tear or push on the flex cable, be careful during installation.
- Before installing the screen, please remove the battery in advance.
- Please tap the screen carefully, because the screen is too fragile to damage.
Quality Control
Strictly tested by the iProGadgets QC Team — every unit is double tested before shipping and ships in good working order. After receiving the part, please check the appearance and test it first: connect the part to the motherboard for a functional test before full installation, and only install once everything works. We are not responsible for any installation mistakes — if you are not experienced with screen replacement, have the part fitted by a professional repair shop.
Shipping
We ship worldwide. Orders are dispatched within 1 to 3 business days, and every package carries a tracking number you can follow on the order page. Delivery typically takes 7 to 10 days after dispatch.
Returns & Warranty
30-day returns on unused, uninstalled parts. The warranty is valid until installed — once a screen has been fitted, the return window no longer applies, which is why we ask you to test before installation.
FAQs
How do I check that LPM140M420 is the panel I need?
Open the machine, lay the screen face down and read the label on the back of the panel. This listing answers for the code LPM140M420 and for the service part 00NY680, and the panel should be 2560 x 1440 on a 14.0 inch glossy front with a 40-pin connector at the bottom right and no screw tabs anywhere on the frame. Some suppliers print this code as LPM140M420 A or LP140M420 — that is the same panel. If the label carries a different number, or the panel you are removing has a matte front, send us a photo of that label and we will tell you honestly which part you need instead of shipping the wrong screen.
What is the difference between this panel and the B140QAN02.0 panel?
They are the two alternates for one display option, and Lenovo list both. LPM140M420 measures 314.82 x 196.1 mm and B140QAN02.0 measures 315.05 x 195.6 mm — under a millimetre apart in each direction, which is why they interchange. Both are 14.0 inch, 2560 x 1440, glossy, 500 cd/m², 100% Adobe RGB, 40-pin eDP at the bottom right with no brackets. Fitment is the same; the difference is which factory built it, and this one is the code still in production. If your machine has been repaired before, measure the bezel opening before you order.
Will this panel fit my machine if it has the Full HD screen?
No. The 14.0 inch Full HD panels used in these families sit on a 30-pin connector, while this WQHD panel uses a 40-pin connector — the two plugs are physically different widths and the machine does not drive the wrong resolution correctly. Count the contacts on the flex of the screen you are removing: about 20 mm across is the 30-pin Full HD panel and about 25 mm is the 40-pin panel in this listing.

Frequently Asked Questions
Is this part compatible with my device?
This listing is for Replacement LCD Screen Display For LPM140M420 14.0 inch WQHD Glossy 500nit Panel. It is built as a direct-fit replacement for the model named in the title. Match the model number in the title against your own device before ordering. If you are not sure which version you need, email sales@iProGadget.com and we will confirm the correct part for you.
What is the quality of these replacement parts?
We supply iProGadgets OEM Quality / Premium Compatible replacement parts. Every part is manufactured to OEM specifications, so the fit, finish and function match the original component it replaces, and each unit is individually tested before it leaves our warehouse.
Is the part tested before it is shipped?
Yes. Every part we sell is inspected before dispatch and tested wherever testing applies — screen assemblies are checked on the panel, the touch response and the connector. Orders are processed and shipped within 1-3 business days after payment is confirmed.
How long does shipping take?
Orders leave our warehouse within 1-3 business days. Express Shipping (DHL, UPS or FedEx) takes 5-8 working days and is normally used for parcels over 2 kg. Registered Air Post takes 10-20 working days and is normally used for parcels under 2 kg. Every order ships with a tracking number. Customs clearance can add extra time, especially during peak season.
Will I be charged import duties or customs fees?
Customs charges depend on your own country's import rules and its de minimis threshold, not on the seller. Some destinations apply no duty at all on lower-value parcels, and where duty or VAT does apply it is collected by your local post office or courier before delivery. We ship every order with complete and accurate commercial documents, which is what keeps a parcel moving through customs instead of sitting in it. If you would like to estimate the charges before you order, email us your country and we will point you to the right authority.
What is your return policy?
We offer a 30-day return policy, which means you can request a return within 30 days of receiving your item. To be eligible, the item must be unused, uninstalled and in the packaging it arrived in. Once a part has been fitted, bonded or used it cannot be returned, so please test the part before installation. To start a return, email sales@iProGadget.com.
What should I do if the part arrives damaged or faulty?
Inspect your order as soon as it arrives. If an item is defective, damaged or not what you ordered, contact us at sales@iProGadget.com straight away with photos or a short unboxing video, and we will arrange a replacement or a refund.
Do you provide repair guides or installation tutorials?
No. We are a supplier of replacement parts only. We are not a repair shop, and we do not provide repair guides, tutorials or step-by-step installation support. Every part we sell is intended to be installed by a professional technician at a qualified repair shop, which also gives the best result: a technician can transfer the small components, handle the adhesives and test the finished repair. Please do not attempt the installation yourself if you have no previous repair experience, as these assemblies are fragile and incorrect handling can damage them permanently. We sell parts only and do not accept responsibility for installation carried out by the customer. Our warranty covers the part itself and remains valid until the part is installed. If a problem appears after the repair, please take the device back to the repair shop that fitted the part so they can inspect the installation and test the device.
Still have a question about this part? Email us at sales@iProGadget.com and we will confirm compatibility, shipping time or return details for you.
