The Dell Inspiron 15 3000 and 5000 series are among the most widely repaired consumer laptops globally—thanks to their affordability, modular design, and long service life. But screen replacements require precise panel matching: wrong interfaces, resolutions, or EDID profiles can cause flickering, black screens, or BIOS warnings. As a direct distributor for BOE, AUO, Innolux, and LG, we supply A Grade, OEM-compatible LCD panels validated for seamless integration across all major Inspiron 15 models—from the 3520 to the 5520.
1. Compatible Panel Models Overview
1.1 Top 3 Most-Requested Panels by Model
We stock the exact panels used in Dell’s original FRUs, including:
Inspiron 15 3520 / 3537:
- Original PN: LP156WH4-TLC1 → Replaced by BOE NV156WHM-N61 (FHD, 220 nits, eDP 30-pin)
- Alternative: AUO B156HTN04.2 (same spec, lower cost)
Inspiron 15 5558 / 5559:
- Original PN: LP156WF6-SPB1 → Supplied as BOE NV156WUM-N61 (FHD, 250 nits, wide viewing angle)
- Premium option: LG LP156WF6-SPD1 (better color gamut, same interface)
Inspiron 15 5570 / 5580:
- Uses eDP 40-pin interface → Innolux N156HCE-GQ1 or AUO B156HAN04.0
- Note: Not compatible with older 30-pin cables—verify before ordering
All panels are cross-referenced against Dell’s service manuals and tested in actual Inspiron units.
1.2 Interface Identification Guide
Misidentifying the eDP connector is the #1 cause of failed installs. Use this quick reference:
| Connector Type | Pin Count | Common Models | Cable Color (Dell OEM) |
|---|---|---|---|
| eDP 30-pin | 30 | 3520, 3537, 5558 | Black |
| eDP 40-pin | 40 | 5570, 5580, 5593 | Gray or white |
We include free interface diagrams with every quote to prevent mismatches.
1.3 Legacy LVDS Support (For Early 3000 Models)
Models like the Inspiron 15 3520 (2012) may still use LVDS (not eDP). We maintain limited stock of:
- Sharp LQ156M1LW01 (1366×768, CCFL backlight)
- Innolux CLAA156WA01 (LED-backlit upgrade option)
Note: LVDS panels require inverter replacement if upgrading from CCFL to LED.
2.Technical Specifications & Brand Comparison
2.1 Resolution and Brightness Standards
All mainstream Inspiron 15 panels are 1920×1080 (FHD). Exceptions include early 3000 models (1366×768). Brightness varies by brand:
| Brand | Typical Brightness | Viewing Angle | Best For |
|---|---|---|---|
| BOE | 220–250 nits | 170°/170° | Cost-sensitive repairs |
| AUO | 250 nits | 178°/178° | Better outdoor visibility |
| LG | 250–300 nits | 178°/178° | Premium resale value |
| Innolux | 220 nits | 160°/160° | Budget bulk orders |
None of these models support OLED or touch—avoid listings claiming “touch upgrade” unless the chassis originally included it.
2.2 Power and Signal Requirements
- Voltage: Standard 3.3V or 5V via eDP (no external power needed)
- Backlight: Integrated LED driver—no inverter required (except LVDS)
- Refresh Rate: Fixed at 60Hz (no high-refresh options available for Inspiron 15)
Panels are not interchangeable between 3000 and 5000 series without verifying cable length and mounting hole alignment.
2.3 EDID Compatibility Notes
Dell BIOS on Inspiron 15 rarely blocks third-party screens—but inconsistent EDID can cause:
- Incorrect resolution detection
- Flickering at boot
- “Unknown display” in Windows
We pre-flash all panels with Inspiron-validated EDID based on model year. Custom EDID available for orders over 50 pcs.
