At ZY LCD Shop, we understand that exact hardware matching is critical for laptop repairs.

FAQ (Frequently Asked Questions)

What does the "HW4A" suffix mean, and why is it important?

"HW4A" stands for Hardware Revision 4A. While multiple revisions of the B140XTK01.0 exist, they may feature slight differences in mounting bracket placement, bezel thickness, or internal component layout. Ordering the exact HW4A revision ensures a 100% physical fit inside your specific laptop chassis without needing to modify the plastic frame or use double-sided tape.

Will the AUO B140XTK01.0 fit my 14-inch Lenovo, Dell, or HP laptop?

This panel uses the industry-standard 14.0-inch slim form factor with a bottom-mounted 30-pin eDP connector. It is compatible with thousands of 14-inch WXGA (1366x768) laptops. However, you must verify that your original screen also uses a 30-pin eDP interface (not 40-pin) and shares the same mounting bracket positions before ordering.

Can I upgrade my 1366x768 screen to a 1920x1080 FHD panel using this model?

No. The B140XTK01.0 is strictly a 1366x768 WXGA panel. Upgrading a laptop from HD to FHD often requires replacing the entire eDP video cable (from 1-lane to 2-lane) and verifying if the laptop's BIOS whitelists higher resolutions. This panel is intended as a direct, like-for-like replacement for your existing HD screen.

Where can I download the B140XTK01.0 HW4A datasheet and pinout definition?

We provide the official AUO PDF datasheet, including precise mechanical outlines, bezel thickness, and 30-pin eDP configurations, to verified buyers. Please contact our engineering support department directly via email or phone to request your copy.

Is this screen matte or glossy?

The B140XTK01.0 features an Anti-Glare (Matte) surface treatment with a 3H hard coating. This reduces distracting reflections from room lighting or windows, which is strongly preferred for business, coding, and educational environments where users stare at text for extended periods.

Do you offer bulk pricing for laptop repair shops and corporate IT departments?

Absolutely. We actively support B2B wholesale orders for computer repair centers, school district IT maintenance teams, and corporate refurbishers. Reach out to our sales department for custom tiered pricing based on your monthly volume requirements.
