Customize the length, width and thickness of FPC or cable, adjust the pin arrangement according to the interface type, and select the appropriate connector. Make your display or circuit board simple and safe with an excellent FPC solution.
A touch screen can be added according to your requirements, there are three options: resistive touch screen, capacitive touch screen, infrared touch screen. Or add protective glass as needed
Display screens with different optical parameters can be designed according to needs, such as brightness, color gamut, response time, gamma and other parameters, and anti-glare, anti-fingerprint coatings, etc. can also be added
The circuit board we designed can convert the interface of your display into an HDMI interface. If your product does not have any display control capabilities, you can use our serial display and only need to use simple commands to control the displayed content through RS232/458
