128x64 COG Display Character Module can display 128*64 dot matrix monochrome pictures, It can display 16 letters, numbers and symbols of *4 rows and 8*16 dot matrix, and can display 21 letters, numbers and symbols of *8 rows and 5*8 dot matrix. Contrast can be adjusted by software, positive display/reverse display conversion, row and column scanning direction can be changed (can be rotated 180 degrees for use).

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

128x64 COG Display Character Module drawings and interfaces

The driver IC of the 128×64 COG Display Character Module is UC1701X from Sitronics, Using 4-wire SPI serial port. The backlight uses two LED beads connected in parallel, the working voltage is 3V, and the working current is 30mA. The power consumption is 1mW when the backlight is not working. Working temperature: -20℃ -+ 70℃, operating temperature: -30℃ – +80℃.

The outline drawing is as follows:
