FAQ

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.

  • 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.

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.

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.

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.

  • 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.

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

Our team has extensive experience and provides a one-stop service—from design, quotation, production, quality inspection, after-sales service, customs clearance to international shipping. You will get factory-direct prices and the convenience of service.
