Frequently Asked Questions (FAQ)

Q1: What is the difference between LP140WH4-TLN1 and LP140WH4-TLA1?

A: They are virtually identical. Both are 14.0" HD 1366x768 panels with a 40-pin LVDS interface. The suffix (N1 vs A1) simply indicates different production batches or minor revisions by LG Display. They are 100% interchangeable and compatible with the same laptops.

Q2: My original screen has a 30-pin connector. Will this 40-pin screen work?

A: No. The LP140WH4-TLN1 uses an older 40-pin LVDS interface. Modern ultra-thin laptops typically use a 30-pin or 40-pin eDP interface. LVDS and eDP are completely different signal technologies and are not cross-compatible. Please check your original screen's connector pin count and type.

Q3: Is the screen surface Matte or Glossy?

A: The standard LP140WH4-TLN1 features a Glossy (Glare) finish with a 3H hard coating, which provides vibrant colors and deep blacks. If your original laptop had a matte screen, you can still use this glossy panel, though it will reflect more ambient light.

Q4: Do you ship internationally and what is the warranty?

A: Yes, ZYLCD ships worldwide via DHL/FedEx/UPS. Every LP140WH4-TLN1 is tested before dispatch and comes with a 12-Month Replacement Warranty against manufacturing defects (excluding physical cracks or water damage caused during installation).
