128x64 COG Display Character Module parameters

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

128×64 COG (Chip-on-Glass) display character module has a resolution of 128×64 pixels, the driver IC is UC1701X, and a 4-wire SPI (Serial Peripheral Interface) serial port is used.

The backlight unit of the 128×64 COG display character module adopts two LED lamp beads connected in parallel. The working voltage of the backlight is 3V, and the working current of 30mA is needed to achieve the best brightness. The power consumption of using lcd alone is 1mW. The 128×64 COG display character modules are also designed to operate reliably over a wide temperature range. It is capable of operating in a temperature range of -20°C to +70°C and can be stored in a temperature range of -30°C to +80°C.

We support the customization of FPC. If you need, you can also add a touch screen, or even a fixed bracket of various materials. Please contact us if you need.
