128x128 COG Display Character Module can display images not larger than 128×128 dot matrix monochrome or 4 gray levels, or display 8×8 lines=64 Chinese characters in 16*16 dot matrix, or display 16×8 rows=128 English, numbers and symbols in 8*16 dot matrix. or show 21 x 16 rows of 5*8 dot matrix English, numbers and symbols.

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
