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
3.95-inch tft display drawings and interfaces
3.95-inch TFT square display, the display uses an IPS mode panel, the display has a square shape and a resolution of 480×480, the driver IC used is ST7701, and supports RGB and MIPI interfaces. The monitor uses a ZIF (Zero Insertion Force) connector. Support customization of FPC, connector and touch screen.
The monitor’s backlight unit consists of eight LED beads carefully designed for optimal illumination. These lamp beads are cleverly configured as four in series and then in parallel, resulting in efficient and uniform lighting across the entire screen. The working voltage of the display is 12.2V, the current is 40mA, and the brightness reaches 350cd/㎡, which can ensure clear and vivid visual effects under various lighting conditions.
Experience the power of innovation with our 3.95″ IPS mode TFT display featuring a square shape, versatile interface options, efficient backlighting and advanced driver ICs. Unlock new possibilities and elevate your applications with our cutting-edge display solutions. “
