A:
This 4-inch touch screen uses projected capacitive (PCAP) touch technology, which provides accurate, responsive multi-touch detection and works well for typical gesture inputs.
A:
Yes. The panel is designed with a durable surface and stable touch performance for industrial and commercial applications; however, environmental sealing and housing design depend on the specific installation.
A:
Interfaces and controller requirements vary depending on the system. Standard capacitive touch panels often interface via USB or I²C through a touch controller board. If needed, we can recommend compatible controllers or custom solutions.
A:
Yes. We offer OEM customization options, including different cover glass specifications, controller tuning, interface adaptations, and mechanical FPC modifications to suit project requirements.
A:
No. This product is a touch screen panel only. It needs to be integrated with a compatible display module (LCD/OLED) or housing system for complete visual output.
