128x64 COG display character module
LCD module 128×64 COG display character module, the driver IC is UC1701X, and adopts 4-wire SPI serial interface.
128x64 COG Display Character Module parameters
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.
