128x32 COG display character module parameters

16x2 COG Display Character Module can display 2 lines, each line has 16 English characters, numbers, symbols, and self-edited characters (each displayed interface can reach up to eight 5*8 dot matrix or four 5*8 self-edited characters) .

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

128x32 COG Display Character Module drawings and interfaces

The 128×32 COG Display Character Module powered by the UC1604c driver IC is an excellent display solution designed for maximum performance and versatility. The module’s compact form factor and 128×32 pixel resolution make it ideal for applications where space is limited but clear character information is required.

The display adopts UC1604c driver IC and supports 4-wire SPI (Serial Peripheral Interface) serial port, which can realize fast and reliable data transmission and ensure smooth integration into various electronic systems. Operating temperature -20°C to +70°C, storage temperature: -30°C to +80°C.

The backlight of the 128×32 COG display character module uses two LED lights connected in parallel, the operating voltage is 3V, and the operating current of 30mA is required to provide the best brightness. When the backlight is not in use, the power consumption of the module is only 1mW, which is suitable for ultra-long standby products. Low power consumption helps extend battery life and save overall energy, making it ideal for portable devices and applications where power efficiency is important. Suitable for small hand-held instruments, solar-powered products.
