FAQ

I. Minimum Order Quantity for Small-Size TFT (Semi-Custom)

Our MOQ is quite flexible. Small-sized semi-custom TFT displays are generally ordered from 100 pieces, and lower quantities can be negotiated for trial production or sampling projects.

III. Under what circumstances is FAE technical support supported?

Mass production or large-volume projectsWhen orders reach a certain scale
Project development phase：The customer is adapting the screen driver, interface voltage or software
special needs：If you need horizontal screen display, touch solution, etc.

V. How do you ensure smooth communication?

Our sales team is familiar with international trade and the technical specifications of TFT displays. We respond quickly (usually within 2 hours) and confirm every detail using complete technical drawings or physical photos and samples before production.

7. Your factory can directly handle shipping and export documents.

We can arrange shipping terms such as EXW, FOB, and CIF, and work with your designated freight forwarder.

Whether it's air freight, sea freight, or express delivery, we can ensure fast and safe delivery.

II. Minimum Order Quantity for Medium-Sized TFTs (Semi-Customized)

Our MOQ is quite flexible. Medium-sized semi-custom TFT displays are generally ordered from 50 pieces, and lower quantities can be negotiated for trial production or sampling projects.

IV. What projects can be customized?

touch screen: Capacitive and resistive touch screen, AG, AF, AR, etc.
Backlight brightnessIt can meet requirements of over 1000 cd/m². (Minolta color analysis instrument)
Industrial and medical：Need to meet specific industry requirements, etc.

VI. Why choose you?

Many overseas customers prefer to use agents due to considerations such as communication, quality, and international logistics.
