128x128 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
128x128 COG display character module drawings and interfaces
The 128×128 COG (Chip on Glass) display character module has a resolution of 128×128 pixels, integrates the ST7571 driver IC, supports a 4-wire SPI interface, and is suitable for various applications that require efficient presentation of character-based information.
The 128×128 COG display character module uses a backlight unit with two parallel LED lamp beads. The working voltage of the backlight is 3V, and the working current is 30mA. The power consumption of the whole module is very low, less than 100mW. This makes it an excellent choice for battery-operated equipment or applications where power efficiency is critical. With its efficient power usage, the 128×128 COG display character modules minimize energy requirements without compromising display quality or functionality.
In addition, the display module is designed with reliability in mind. It is designed to withstand a wide operating temperature range from -20°C to 70°C. This feature ensures that the display module will operate consistently and reliably even under harsh environmental conditions with frequent temperature fluctuations. In addition, the module has a storage temperature range of -30°C to 80°C, allowing safe and convenient storage without any adverse effect on its performance.
