While most modern laptops use eDP interfaces, thousands of legacy Dell systems—like the Inspiron N5010, Studio 1737, Latitude D630, and Inspiron 1520—still rely on LVDS (Low-Voltage Differential Signaling) screens with CCFL or early LED backlights. These models remain in active use in schools, small offices, and developing markets—but OEM panels are long discontinued. As one of the few global suppliers still holding verified LVDS inventory, we provide A Grade replacement panels from Sharp, Innolux, and AUO, including both original CCFL and upgraded LED-backlit versions.
1. Supported Models & Panel Cross-Reference
1.1 Most-Requested Legacy Models
We specialize in hard-to-find panels for these frequently repaired systems:
Dell Inspiron N5010 / N5050:
- Original: LP156WH2-TLB1 (1366×768, CCFL)
- LED Upgrade: Innolux CLAA156WA01 (same resolution, LED backlight, no inverter needed)
Dell Studio 1737 / 1749:
- Rare 17″ panel: Sharp LQ170W1LW01 (1440×900, CCFL) — one of the last sources globally
- Requires original CCFL inverter or retrofit kit
Dell Latitude D630 / D830:
- 14.1″ XGA (1024×768): AUO B141EW03 V5
- Ideal for government/military depot repairs
All panels are tested on original motherboards to confirm signal compatibility.
1.2 CCFL vs LED Backlight: What You Need to Know
- CCFL Panels: Require a high-voltage inverter (typically 1–2 pin). Common in pre-2012 models.
- LED-Upgraded Panels: Use low-voltage DC power (no inverter), but may need cable modification.
⚠️ Crítico: Do not install an LED panel without verifying power source. Forcing 19V into a CCFL-only socket can damage the motherboard.
We offer free wiring diagrams and can bundle inverter-to-LED adapter kits (MOQ 10 pcs).
1.3 Connector & Resolution Guide
| Modelo | Tamaño de pantalla | Resolución | Interface | Iluminar desde el fondo | Common PN |
|---|---|---|---|---|---|
| Inspiron N5010 | 15.6″ | 1360×768 | LVDS de 30 pines | CCFL | LP156WH2-TLB1 |
| Studio 1737 | 17.0″ | 1440×900 | LVDS de 30 pines | CCFL | LQ170W1LW01 (Sharp) |
| Inspiron 1520 | 15.4″ | 1280×800 | 20-pin LVDS | CCFL | B154EW01 (AUO) |
| Latitude D630 | 14.1″ | 1024×768 | 18-pin LVDS | CCFL | B141EW03 (AUO) |
Note: Pin count and timing must match exactly—LVDS is not plug-and-play like eDP.
2.Sourcing Strategy for End-of-Life Panels
2.1 Why Stock Is Extremely Limited
LVDS panels were phased out by 2015. Most factories have:
- Destroyed tooling molds
- Recycled remaining glass stock
- Discontinued driver IC production
Our inventory comes from final factory lots y enterprise liquidation batches—all date-coded between 2013–2016.
2.2 Quality Control for Aged Panels
Despite age, we enforce strict A Grade standards:
- Zero dead pixels (tested under magnifier)
- No yellowing or clouding in CCFL tubes
- Backlight uniformity ≥ 85% across screen
- Functionality verified on original Dell boards
Panels showing any degradation are downgraded to “B Grade” (sold separately at discount).
2.3 Last-Time Buy Recommendations
For institutions managing fleets of legacy hardware:
- Place bulk orders now—replenishment is impossible
- Minimum recommended stock: 20–50 units per model
- We offer reserved inventory agreements (hold for 90 days with 30% deposit)
3.Ordering & Technical Support
3.1 Required Information for Accurate Matching
To avoid costly mismatches, please provide:
- Original panel part number (e.g., LP156WH2-TLB1)
- Photo of LVDS connector + backlight cable
- Whether you’re using CCFL inverter or upgrading to LED
We respond within 4 business hours with compatibility confirmation.
