Parts & Tools
Where to source a replacement e-ink panel for the X3 (3.7″) or X4 (4.3″), plus the spudgers, tape and tools the swap needs, with real prices and the one panel to avoid.
Buying parts before you’ve decided it’s worth it? Start with repair or replace: on a $69–$79 reader the math often points the other way.
Resolution alone is not a safe match filter. The genuine e-reader-grade 4.3″ 800×480 panel (E Ink ED043WC3 / ED043WC1 class, almost certainly what’s inside the X4) uses a 39-pin 8-bit parallel flex connector. The cheap, heavily-advertised “4.26-inch 800×480” hobbyist modules (Waveshare / Good Display GDEY0426T82) use a completely different 24-pin SPI bus.
Same pixel count, electrically incompatible.
Buying the popular 4.26″ SPI module will not work. No public X4 teardown has yet confirmed the exact pin map, so even a “parallel” panel is a gamble until you open the device and physically verify the connector.
Why same resolution ≠ compatible: parallel and SPI are two different wiring schemes for talking to the panel. A parallel bus moves many bits at once over many wires (here ~39 pins); SPI streams bits one at a time over far fewer (here 24 pins). The pixel count says nothing about which bus a panel speaks. The X4’s controller only speaks one.
Before you open anything: opening the case voids the warranty. If the screen died with no drop or impact and the unit is still within its 1-year window, try Strategy 1 or the warranty guide first, before cracking the case open just to check a connector.
This trap is X4-specific: the X4 needs a parallel-interface panel. The X3’s 3.7″ panel is a different size and likely uses SPI itself (see the X3 note below), so this particular warning does not transfer directly, check the X3’s own caveat instead. Both device-specific walkthroughs link back to this page for the fuller explanation: X4 screen replacement and X3 screen replacement.
Xteink does not sell replacement panels and no official spare-parts market exists as of June 2026. Worth knowing before you shop: no one in the r/xteinkereader community has ever posted a working replacement-panel link — the repair threads only ever say “buy a generic e-ink display, use a hairdryer + alcohol, and have patience.” That gap is exactly why the interface warning above matters.
Email support@xteink.com (web orders) or help@xteink.com (Amazon/TikTok orders), or use the contact form. Ask for a paid panel or repair. The X4 ships with a 1-year warranty (cracks not covered, see the return policy), but they may still sell a part on request.
Cost: unknown, negotiate. Risk: may be declined; slow.
Target the parallel-interface family that matches the X4’s class:
Avoid: Waveshare / Good Display 4.26″ SPI modules and all 4.2″ (400×300) panels.
Risk: pinout / VCON (a factory-calibrated panel voltage, see below) still unverified, order one and verify physically.
Buy a cheap broken or working X4 or X3 as a donor (a second unit bought for its parts) for a guaranteed-correct screen and connector. Set an eBay saved search for “xteink X4 for parts” (X3 version) — no “for parts” units were listed at last check, so working units (~$80–90, e.g. this X4) may be the only donor available. Also ask in r/xteinkereader.
Cost: ~$20–50 broken / ~$80–90 working. Risk: the donor screen may also be cracked.
The X4 uses an E Ink Corporation greyscale panel. The exact model number was not documented in any teardown, but the display characteristics are confirmed. Match these against a candidate before ordering.
| Parameter | X4 (4.3″) | X3 (3.7″) |
|---|---|---|
| Screen diagonal | 4.3 inches | 3.7 inches |
| Resolution | 800 × 480 px | Not published; retail 3.7″ e-ink panels are 416 × 240 (verify) |
| Pixel density | 220 PPI | 259 PPI claimed (inconsistent with 416×240 — re-check before sourcing) |
| Display type | E Ink (greyscale, reflective) | E Ink (greyscale, reflective) |
| Backlight | None (no frontlight) | None (no frontlight) |
| Touch layer | None (physical buttons only) | None (physical buttons only) |
| Controller chip | ESP32-C3 host driving an E Ink panel of the ED043WC3/WC1 class | Same ESP32 platform (variant unconfirmed) |
| Interface | Likely 39-pin 8-bit parallel (ED043WC3 class) — not the 24-pin SPI of 4.26″ hobby modules | Likely SPI (3.7″ class, unverified) |
| Connector | ZIF / FPC flex; ED043WC3 class = 39 pins (open device & verify before ordering) | ZIF flex cable (pin count unconfirmed) |
| Magnetic ring | Embedded in screen assembly | Embedded in back plate |
Important caveat: the exact panel model number and connector pinout have not been publicly confirmed in any teardown as of June 2026. Open the device first, photograph the flex cable and connector markings, and order only after verifying the pin count and pitch match. (ZIF = zero-insertion-force; FPC = the flat flex / ribbon cable that plugs into it.) Opening the case is itself a warranty-voiding step, so if the screen failed with no drop or impact and the unit is still within its 1-year window, rule out a free warranty claim before you crack the case open.
For the X3 specifically: the resolution and pixel-density figures above do not agree with each other, so don’t shop by spec until that’s resolved. The donor-unit route (Strategy 3) sidesteps the problem entirely by guaranteeing a matching panel.
Every e-ink panel has a calibrated compensation voltage called VCON, typically 1.00 V to 2.5 V. It is specific to each panel batch and printed on a small label tag attached to the replacement screen.
For most hobbyist repairs with a near-identical panel the VCON difference is small and any artifacts are minor. A fresh CrossPoint flash after installation often helps clear display memory and reduce ghosting.
Based on the X4 teardown (glue-based construction, one flex-cable connector, metal back cover) and established e-ink replacement technique from iFixit and e-ink-reader.ru.
| Tool | Priority | Purpose & notes |
|---|---|---|
| Heat gun (or hair dryer) | Must have | Soften the adhesive holding the metal back cover. Set to lowest heat, 8–10 inches away, sweeping motion. 1–2 minutes to reach working temperature. Do not hover in one spot — overheating warps the PCB and can damage the panel. |
| Plastic pry tools / spudgers | Must have | Open the case after heating without scratching. Start at a corner and work around the edges. Use plastic — metal pry tools mark the aluminium shell and can short internal components. |
| Metal spudger | Must have | Disconnect the ZIF (zero-insertion-force) flex-cable connector from the main board. Hook gently on both sides of the connector lock to avoid tearing the ribbon cable. |
| Precision screwdriver set (Phillips #00, #0; flathead) | Must have | May be needed for any internal bracket screws (the teardown shows the function-button cable fixed by a metal strip). Phillips #0 is the common size for this class of device. |
| Tweezers (fine-tip, anti-static) | Must have | Handle the flex-cable connector lock, remove glass fragments, and position the replacement panel. |
| Cut-resistant gloves | Must have | Mandatory for handling any cracked e-ink panel. The glass is extremely thin and produces invisible splinters. |
| Double-sided tape (0.5 mm or thinner) | Must have | Re-adhere the replacement panel inside the frame. Thicker tape prevents the case from closing properly. Source from stationery suppliers or electronics repair shops. |
| Isopropyl alcohol (IPA) 90%+ | Must have | Clean old adhesive residue off the frame before installing the new panel. Do not use water or lower-concentration IPA — they leave moisture. |
| Suction cup (small) | Helpful | Assist lifting the back cover after adhesive is softened. Optional if your pry-tool edges are sufficient. |
| Opening picks / guitar picks | Helpful | Keep the case open while you work. Wedge between the halves after initial prying. |
| Plastic scraper / opening tool | Helpful | Score and cut old adhesive residue from the panel frame before cleaning with IPA. |
| Anti-static mat or wrist strap | Optional | The ESP32-C3 and e-ink controller are ESD-sensitive (vulnerable to static discharge). Recommended if working on carpet or in dry conditions. |
| Magnification (loupe or phone macro) | Optional | The flex-cable connector is very small. A 10× loupe or a phone with macro mode helps confirm it is fully seated. |
| Digital multimeter | Optional | Check the VCON voltage if the replacement panel behaves unexpectedly (blotchy refresh, ghosting). See the VCON note. |
The X4’s case is held together with thermal adhesive / hot-melt glue around the back-cover edges. For a DIY re-close you have three options:
Specific products verified June 2026. iFixit prices were confirmed live (on a site-wide sale);
Amazon prices are typical street prices (marked ~) because Amazon
hides them from automated checks — the /dp/ links are real
listings, but confirm the current price and fit before buying.
One kit covers most of this
The iFixit Pro Tech Toolkit (~$68) covers the spudgers, pry tools, picks, precision driver, suction cup and anti-static strap in one box; you then only add consumables (IPA, B-7000, tape, gloves, heat gun). Cheaper iFixit options: Essential Electronics Toolkit (~$25) or the Minnow driver kit (~$13). Budget all-in-one on Amazon: ORIA 142-in-1 precision set (~$25).

The X3 uses a 3.7″ panel, not the same as the X4’s 4.3″. Its exact resolution and pixel density are unconfirmed and the figures don’t agree with each other (see the caveat in the specs section above), so the donor-unit route (Strategy 3) is the safer way to source an X3 panel until that’s resolved. The X3 also uses a proprietary magnetic pogo-pin charger (spring-loaded contact pins), not USB-C: do not lose that cable, as the device cannot be charged otherwise. If it’s already lost, check the accessories page for a spare cable or adapter.
Prevention beats repair on a $69 reader: screen protectors and the rest of the owner essentials cost a fraction of a panel swap.
