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

0.91-inch OLED Display drawings and interfaces

The 0.91-inch monochrome OLED display has a high resolution of 128×32 pixels and provides crisp white content. The driver IC is SSD1316, which supports I2C serial interface. The FPC is connected by welding without connectors, ensuring stability and low cost.

Due to the self-luminous nature of OLED technology, our displays do not require an additional backlight, increasing power efficiency. It requires at least a 3V power supply to operate efficiently, reducing energy consumption. In addition, the OLED panel guarantees excellent viewing angles, providing excellent visibility from all directions. Furthermore, since there are no liquid crystal components, our displays exhibit reliable performance even under extreme temperature conditions.

The outline drawing is as follows:

Interfaces are defined as follows:

1C2PData transmission line
2C2NData transmission line
3C1PData transmission line
4C1NData transmission line
5VBATPower Supply for DC/DC Converter Circuit
6VBREFNC
7VSSThis is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground
8VDDThis is a voltage supply pin. It must be connected to external source
9RESThis pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation.
10SCLIIC Bus Clock Signal
11SDAI2C Bus Data Signal
12IREFCurrent Reference for Brightness Adjustment
13VCOMH 
14VCCThis 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.
