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

1.28-inch tft display drawings and interfaces

The 1.28-inch round display with a resolution of 240×240 is highly versatile and can be used in a variety of applications. The circular LCD display is a popular choice in wearable technology, smartwatches, and other small electronic devices. The display’s IPS mode ensures that colors are accurate and vibrant, making it a great option for displays that need to show a range of colors and images.
The display uses a driver IC GC9A01, and support 4-line SPI interface ensures that the display has a fast response time and is easy to program.
The backlight of the display uses 2 LED lights in parallel, ensuring that the module has a bright and even illumination. The brightness of the display is 400cd/㎡, making it easy to read in different lighting conditions. Additionally, the display has a wide working temperature range of -20℃~+80℃, making it suitable for use in a variety of environments.

The outline drawing is as follows:

Interfaces are defined as follows:

2LEDKbacklight unit power supply
3LEDASPI interface input/output pin.the data is latched on the rising edge of the
SCL signal. 
4VDDThis is a voltage supply pin. It must be connected to external source
7DCDisplay data/command selection pin in 4-line serial interface.
8CSChip selection pin;Low enable,high disable. 
9SCLThis pin is used to be serial interface clock 
10SDAThis pin is used to be serial interface clock 
11RESThis signal will reset the device and it must be applied to properly initialize
the chip.Signal is active low.
