AI Overview
A 4-inch IPS TFT LCD typically features a
or
resolution, offering wide viewing angles and vivid color reproduction, ideal for embedded systems, industrial controls, and smart home devices. Popular variants include high-brightness (800-1000 nits) sunlight-readable screens with capacitive or resistive touch panels, commonly utilizing ST7701S/SN drivers with MIPI DSI or RGB interfaces.
Common 4-inch IPS TFT LCD Specifications
- Resolution: 480x480 (Square) or 720x720
- Technology: IPS (In-Plane Switching) for full viewing angles (typically ~80° off-axis)
- Brightness: 300 nits (standard) to 1000 nits (high-brightness/sunlight readable)
- Interface: MIPI DSI (2-lane) or RGB (Parallel) + SPI for configuration
- Touch Options: Capacitive (CTP) or 4-Wire Resistive (RTP)
- Controller/Driver: Usually ST7701S/ST7701SN
Popular Models & Types
- Newhaven Display NHD-4.0-480480AF: 480x480 square, MIPI DSI, 850 nits, available with Capacitive or Resistive touch. Features EMI shielding.
- Waveshare 4-inch Raspberry Pi Display: 720x720, IPS, Capacitive touch, designed for 40-pin GPIO, supporting Raspberry Pi systems.
- BuyDisplay ER-TFT040-3: Square 480x480, SPI+18bit RGB interface, optional touch panel.
- High-Brightness Industrial Unit: 480x480, 1000 nits, ST7701S, designed for harsh environments and, high readability.
Key Considerations
- Interface: Ensure your microcontroller supports MIPI DSI or has enough pins for 24-bit Parallel RGB, as these are common for higher resolution 4-inch screens.
- Mounting: Most industrial panels (e.g., Newhaven) do not have built-in mounting holes and rely on bezel mounting.
- Touch Capability: Capacitive models (e.g., using FT5426G) support multi-touch, while resistive models work with styluses and gloves.
