3.1-inch IPS TFT LCD Display Module – 480×800 HD, MIPI Interface, 350 nits, All Viewing Angle, Touch Optional
3.1-inch IPS TFT LCD Display Module – HD Resolution, MIPI Interface, Industrial Grade with Optional Touch
Saef Technology Limited introduces a high-performance 3.1-inch IPS TFT LCD module, engineered for applications that demand excellent viewing angles, consistent color reproduction, and reliable operation. Featuring 480×800 HD resolution, MIPI interface, and optional capacitive touch, this display is ideal for portable medical devices, handheld instruments, industrial HMIs, smart home controls, and embedded systems where space, clarity, and interactivity are critical.
Key Features & Technical Advantages:
- IPS Technology for Consistent Viewing Angles
80° viewing angle in all directions ensures minimal color shift and consistent image quality from any perspective—ideal for multi-user or off-axis viewing applications.
- High Resolution & Color Performance
480×800 pixels with 16.7M color support deliver sharp text, graphics, and icons. NTSC gamut up to 60% provides vibrant and accurate color representation.
- MIPI Interface for High-Speed Data Transfer
2-lane MIPI (D-PHY) reduces EMI, simplifies layout, and enables low-power operation—perfect for portable and battery-powered designs.
- Wide Operating Temperature Range
Rated for -20°C to +60°C, ensuring stable performance in varying environmental conditions, from indoor control panels to field-deployed devices.
- Integrated Touch Interface Ready
Pre-configured I²C pins (CTP_INT, CTP_RST, CTP_SDA, CTP_SCL) allow easy integration of capacitive touch panels for interactive applications.
- Low Power Consumption with ST7701S Driver
Typical current consumption as low as 30mA in normal mode and 100µA in standby—optimized for energy-sensitive designs.
- Compact Form Factor
Module size of 43.48mm × 74.72mm × 1.6mm (excluding FPC) allows integration into space-constrained products without compromising display area.
- Customizable Touch & Mechanical Options
We offer semi-custom design services—add capacitive or resistive touch, modify bezels, adjust mounting points, or tune display firmware to match your system requirements.
Designed for Reliable Integration in Demanding Applications
Saef’s 3.1-inch TFT module addresses key engineering challenges in embedded display design:
-
MIPI signal integrity support with built-in impedance matching and noise suppression
