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.
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.
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.
2-lane MIPI (D-PHY) reduces EMI, simplifies layout, and enables low-power operation—perfect for portable and battery-powered designs.
Rated for -20°C to +60°C, ensuring stable performance in varying environmental conditions, from indoor control panels to field-deployed devices.
Pre-configured I²C pins (CTP_INT, CTP_RST, CTP_SDA, CTP_SCL) allow easy integration of capacitive touch panels for interactive applications.
Typical current consumption as low as 30mA in normal mode and 100µA in standby—optimized for energy-sensitive designs.
Module size of 43.48mm × 74.72mm × 1.6mm (excluding FPC) allows integration into space-constrained products without compromising display area.
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.
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
Precise power sequencing guidelines to prevent latch-up and ensure long-term reliability
FPC with reinforced bend areas for reliable connections in compact or foldable designs
Detailed initialization code and timing diagrams provided for faster software integration
Whether you’re developing a portable diagnostic tool, an industrial handheld terminal, a smart thermostat, or a wearable device interface—this module delivers consistent performance and ease of integration.
Engineering-First Support: Our team provides signal integrity analysis, firmware customization, and thermal design guidance.
Fast Prototyping: Samples ship within 5–7 business days with complete documentation.
Quality & Traceability: Each unit is tested per AQL standards (Major 0.4, Minor 1.0) and supports full batch traceability.
Global Compliance: ROHS-ready and compatible with EU/US market requirements.
