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 driver IC of the 128×32 COG Display Character Module is UC1604c, which uses a 4-wire SPI serial port. The backlight uses two LED lights in parallel, the working voltage is 3V, the working current is 30mA, and the power consumption is 1mW when the backlight is not working. Working temperature: -20°C – +70°C, storage temperature -30°C – +80°C.
The outline drawing is as follows:
Interfaces are defined as follows：
| NO. | Symbol | Detail |
| 1 | LEDA | Backlight power supply |
| 2 | LEDK | Backlight power supply |
| 3 | VLCD | LCD double voltage output |
| 4 | VB1+ | |
| 5 | VB1- | |
| 6 | VSS | Ground |
| 7 | VDD | Positive pole of power supply |
| 8 | SDA | serial data |
| 9 | SCLK | serial clock |
| 10 | RS | H: data register 0: instruction register |
| 11 | RST | Low level reset, after the reset is completed, return to high level, the LCD module starts to work |
| 12 | CS | Chip Select |
