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
1.44-inch tft display drawings and interfaces
The 1.44-inch sunlight-readable display is a high-quality display with excellent brightness, making it ideal for use in outdoor environments. The driver IC used is ST7735, which supports both MCU and SPI interfaces. The module brightness of 500cd/㎡ ensures clear visibility even in harsh sunlight. It features TN mode TFT display technology with a resolution of 128×128, ensuring your content is displayed crisp and clear.
backlight use 2 LED beads in parallel, working voltage 3.2V, working current 40m, very energy efficient. With its high brightness display capabilities, the display is ideal for a variety of applications where visibility is critical, such as smart watches, fitness trackers, and other wearable devices.
