Here we provide a detailed introduction to this 4-inch square 480×480 PCAP TFT (40-pin, RGB + SPI dual interface) display module, along with its usage and accompanying pictures.

Product Core Introduction

This is a compact square IPS full-view TFT liquid crystal display module, commonly equipped with ST7701S driver IC, integrating a **projected capacitive touch (PCAP)** panel, using a 40-pin FPC interface, and supporting high-speed RGB parallel interface (often 18/24 bits) and SPI serial interface; SPI is mainly used for initialization configuration, while RGB is responsible for high frame rate pixel rendering, balancing flexibility and display performance.
Key Specifications: Diagonal 4 inches, 480×480 square resolution, IPS panel provides 178° full viewing angle; common brightness 350~500 cd/m², some industrial models can reach 800 cd/m²; operating temperature mostly -20ºC~70ºC, industrial grade can reach -30ºC~80ºC; PCAP supports multi-point touch, assisted communication through I²C; power supply generally 3.3V.
Structural Dimensions: Effective display area approximately 71.86×70.18 mm, the overall size varies slightly depending on the packaging, common compact specifications of 84×84×3.2 mm or 78~79 mm, 40-pin FPC facilitates direct welding or ZIF socket connection for embedded devices.
Advantages and Features: Square screen is suitable for dashboard, smart home panels, etc., for symmetrical UI design; dual interface is compatible with different main controllers (STM32, ESP32-S3, Raspberry Pi, etc.); PCAP touch does not require additional buttons, interaction is intuitive; IPS full viewing angle avoids color shift when viewed from the side; anti-static and wide temperature characteristics meet the needs of industrial and outdoor scenarios.

Main Applications

Smart Home and Building Control: 86 wall switches, central air conditioning panels, smart locks, video intercoms, with integrated square screen display and touch operation, presenting a simple and elegant design.
Industrial Control and Handheld Devices: Portable instruments and meters, PLC human-machine interfaces, warehouse scanning terminals, environmental monitors. Wide temperature range and high brightness ensure clear visibility in workshops or outdoor strong light conditions.
Medical Health Equipment: Small electrocardiogram monitors, blood oxygen meters, secondary screens for portable ultrasound devices, IPS color accuracy and sterile touch panels facilitate quick operation by medical staff.
Consumer Electronics and IoT Terminals: Portable Bluetooth speakers, extended screens for smart wristbands/wristwatches, pet feeding control panels, small-sized HMI for vehicles.
Embedded Development and Maker Projects: As the display and interaction core of DIY devices, it is compatible with open-source hardware solutions to quickly build prototypes.
