2. What is the typical Minimum Order Quantity (MOQ) for TFT LCD panels?
For standard sizes (7-inch, 10.1-inch), MOQ is usually 500 to 1,000 pieces. For custom designs (special size or optical bonding), MOQ can be 2,000 to 5,000 units. Some suppliers offer sample orders of 10-50 pieces at a premium (2x-3x unit price).
3. Can I get custom display sizes or interfaces?
Yes, most reputable manufacturers offer customization services, including custom resolution, touch panel integration (capacitive or resistive), and interface options (LVDS, eDP, MIPI, HDMI). Lead time for custom products is typically 8-10 weeks after design approval.
4. Do you provide logistics and customs clearance support?
Many suppliers offer DDP (Delivered Duty Paid) terms for major markets like the US, EU, and Brazil. This means they handle shipping, insurance, and customs clearance. Always confirm the Incoterms and ask for a customs duty estimate before placing an order.
5. What quality assurance measures are in place?
Reputable suppliers conduct 100% visual inspection and aging tests (24-48 hours at 50°C). They also provide a Certificate of Conformance (CoC) with each batch. For critical applications, request a Factory Acceptance Test (FAT) before shipment.
6. What payment terms are safe for international transactions?
Standard safe terms include 30% deposit and 70% against a copy of shipping documents (BL/AWB). For larger orders (over USD 50,000), consider a Letter of Credit (L/C) at sight. Avoid 100% upfront payment unless you have a long-standing relationship.
7. How does the pantalla LCD TFT compare to OLED in terms of burn-in?
LCD TFT displays are virtually immune to burn-in because the liquid crystal material does not degrade permanently from static images. OLEDs, especially older models, can experience burn-in after 2-3 years of static content. For industrial or signage applications where static images are common, LCD TFT is the safer choice.
8. Are there any environmental disposal concerns?
LCD panels contain liquid crystal material and mercury (in old CCFL backlights). Modern LED-backlit LCDs are more eco-friendly. Ensure your supplier participates in a take-back or recycling program compliant with the WEEE Directive (EU) or local regulations.
