Invitation lcd video greeting card

Selecting the screen depends on the balance between visual impact and portability. Common sizes range from 2.4 to 10.1 inches. For high-end invitations, a 7-inch or 10-inch IPS screen is recommended as it offers wider viewing angles and higher resolution (1024x600 or 1280x720). Ensure the aspect ratio of your video content matches the screen (usually 16:9) to avoid black bars or stretching.

Standard cards use rechargeable lithium batteries ranging from 300mAh to 1500mAh. For a 7-inch screen, a 1000mAh battery typically provides 90-120 minutes of continuous playback. Regarding storage, 128MB to 256MB is sufficient for short clips, but for high-definition marketing videos, specify 1GB or 2GB flash memory. Always confirm the use of Grade A battery cells to prevent swelling during long-term storage.

Since these products contain lithium batteries and circuit boards, they must meet CE, RoHS, and FCC certifications for international trade. For the US market, ensure compliance with California Proposition 65 regarding lead and phthalates in the paper coating. If shipping by air, the supplier must provide a UN38.3 test report and MSDS (Material Safety Data Sheet) to comply with aviation safety regulations.

The most popular trigger is the magnetic induction switch (video plays automatically upon opening). Other options include light sensors or push buttons. For the exterior, specify 300g-350g art paper with finishes like matte/glossy lamination, foil stamping, or UV spotting to enhance the premium feel. Request die-cut templates from the supplier early in the design phase to ensure artwork alignment.

Electronic components are sensitive to humidity and temperature. Require the supplier to use anti-static vacuum packaging and include desiccants in each master carton. Ensure the batteries are charged to approximately 30%-50% (the optimal level for transport) to prevent deep discharge, which can permanently damage the battery's capacity before it reaches the buyer.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for free spare units (usually 1-2%) to cover potential electronic defects. Ask for a tiered pricing structure where the unit price drops as your volume increases. On Made-in-China.com, prioritize Audited Suppliers and use the Star Rating system to identify partners with high reliability and proven export records.

Utilize Secured Trading Services provided by the platform to protect your payment until delivery. For quality assurance, mandate a Pre-Shipment Inspection (PSI) by a third party. The inspector should check video playback stability, button responsiveness, and paper alignment on at least 10% of the total order. Never release the final 70% balance payment until the inspection report is approved.

Products with integrated batteries are classified as 'Dangerous Goods' (Section II of PI967) in air freight. This often results in higher shipping costs and limited carrier options. To save costs, consider Sea Freight or Rail Transport for large volumes (over 500 units), and ensure the outer cartons carry the mandatory Lithium Battery Handling Label to avoid customs delays or rejections.
