Product Description
H020SQC45T2520 is a 2-inch TFT LCD module with a 45-pin MCU interface. It has a resolution of 176×220 (QCIF+ level) and a display ratio of approximately 4:5, suitable for vertical display scenarios such as handheld instruments and smart wearables. It supports 65K to 262K true color, controlled by the driver chip ILI9225G, with natural color reproduction, meeting the basic graphic interface requirements. The brightness is 220 cd/m², with a viewing angle of 12 o'clock direction (straight view), and some models can reach full viewing angle, suitable for fixed-viewpoint operation scenarios. It supports custom capacitive or resistive touch screens (TP) to meet human-computer interaction needs. The 2-inch TFT LCD Display is a small-sized TFT-LCD screen widely used in industrial control, medical equipment, and consumer electronics, featuring compact size, flexible interface, and strong environmental adaptability. It is suitable for the high stability requirements of embedded systems and portable devices, mainly applied in industrial control and instrumentations: in human-machine interfaces such as PLC, data collectors, and temperature controllers, the 2-inch 176×220 screen is used to display real-time data, status indicators, and operation menus. Its MCU interface and high stability characteristics are compatible with the anti-interference requirements of industrial sites. Portable medical devices: used for blood glucose meters, blood pressure monitors, and portable monitors, clearly displaying measurement results and trend graphs. The low power consumption design extends battery life, suitable for home and mobile medical scenarios. Consumer electronics: used in MP3 players, digital photo frames, electronic dictionaries, etc., providing colorful display effects to enhance user interaction experience. Smart home: as a small control panel, used to display temperature humidity, air quality, etc.
