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
2.08-inch OLED Display drawings and interfaces
2.08-inch monochrome OLED display with a high resolution of 256×64 pixels. With its passive-matrix OLED display mode and 16-level grayscale, the display renders crisp white content, ensuring excellent visual quality.
The display is powered by a reliable SH1122 driver IC and supports 3-wire and 4-wire serial interfaces. This versatility can be seamlessly integrated into various projects and systems, providing convenience and flexibility.
For enhanced durability and reliability, our displays feature soldered FPC (Flexible Printed Circuit) construction. This rugged design ensures long-lasting performance even in demanding environments. The monitor can withstand a wide operating temperature range, with an impressive operating temperature range of -40°C to 70°C and a storage temperature range of -40°C to 85°C.
The outline drawing is as follows:
Interfaces are defined as follows：
| Pin | Symbol | Detail |
| 1 | VSS | GND |
| 2 | BS2 | Communication interface selection |
| 3 | BS1 | Communication interface selection |
| 4 | BS0 | Communication interface selection |
| 5 | NC | |
| 6 | VCC | Power supply for panel driving voltage |
| 7 | VCOMH | |
| 8 | IREF | This is segment output current reference pin. A resistor should be connected between this pin and VSS to maintain the IREF current at 10uA |
| 9 | D7 | These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL. |
| 10 | D6 | |
| 11 | D5 | |
| 12 | D4 | |
| 13 | D3 | |
| 14 | D2 | |
| 15 | D1 | |
| 16 | D0 | |
| 17 | E(RD) | When interfacing to a 6800-series microprocessor, this pin will be used as the Enable (E)signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect to VDD)and the chip is selected. When connecting to an 8080-series microprocessor, this pin receives the Read (RD#)signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial interface is selected, this pin must be connected to VSS |
| 18 | R/W | This is read / write control input pin connecting to the MCU interface. When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH (i.e.connect to VDD) and write mode when LOW. When 8080 interface mode is selected, this pin will be the Write (WR) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS. |
| 19 | D/C | This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDD), the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS. |
| 20 | RES | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation |
| 21 | CS | this pin is the chip select input. (active LOW) |
| 22 | VDD | Power supply pin for core logic operation. |
| 23 | NC | |
| 24 | VSS | GND |
