Specification of 0.42-inch small oled display
initial code for 0.42-inch small oled display
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
0.42-inch OLED Display drawings and interfaces
0.42-inch OLED display panel with a resolution of 72×40 and displays white. The driver IC is SSD1306B, which supports I2C interface and SPI interface. OLED displays do not require an additional backlight, so they have lower power consumption. The display fpc is welded. Many parameters of the OLED display can be customized, such as the length and interface definition of the LCD display FPC, the colors that can be displayed by a single-color OLED, etc. If you need a customize display, please contact us.
The outline drawing is as follows:
Interfaces are defined as follows:
Pin | Symbol | Detail |
1 | VSS | This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground. |
2 | TP/NC | NC |
3 | VSS | |
4 | C2P | Data transmission line |
5 | C2N | Data transmission line |
6 | C1P | Data transmission line |
7 | C1N | Data transmission line |
8 | VBAT | This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be connected to VDD when the converter is not used. |
9 | VDD | This is a voltage supply pin. It must be connected to external source. |
10 | CS | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. |
11 | RES | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. |
12 | DC | Data/Command Control |
13 | SCLK | Host Data Input/Output Bus |
14 | SDIN | Host Data Input/Output Bus |
15 | VCOMH | This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS. |
16 | VCC | This is the most positive voltage supply pin of the chip. A stabilization capacitor should be connected between this pin and VSS when the converter is used. It must be connected to external source when the converter is not used. |
0.42 -inch 72x40 OLED display application cases
Due to the convenience of driving and relatively low price, 0.42-inch 72×40 OLED products are more suitable for use at higher temperatures than TFT LCD because there is no backlight source, such as heating equipment, such as electric soldering iron and heat gun.
Small instruments and other products that do not need to display complex data and images are also suitable for using monochrome OLED. Monochrome OLED can be thinner, and fewer leads, which can take up less of your CPU’s I/O port.
