Product Description

H028SQ40E3547-T is a 2.8-inch TFT LCD module with resistive touch functionality. The resistive screen is triggered by pressure sensing and not only supports finger operation but also can perfectly accommodate glove operation or precise clicking using a stylus. This is crucial in cleanroom environments, outdoor operations, and medical surgery scenarios. The structure is relatively simple, and the module cost is significantly lower than that of capacitive screens. The driving circuit is mature and easy to integrate into cost-sensitive batch industrial equipment. The MCU interface has a higher refresh rate, suitable for displaying dynamic waveforms or rapidly changing parameters. This 2.8-inch resistive touch TFT LCD Display is an extremely cost-effective interaction solution in industrial control and embedded development, with advantages such as low cost, support for glove operation, and strong anti-interference capabilities, making it the preferred display component for medical equipment, industrial control panels, and handheld terminals. It is mainly applied in: Industrial control and human-machine interface (HMI): In PLC control panels, frequency converter operators, and automation equipment, the resistive screen can resist electromagnetic interference and allows operators to wear thick protective gloves for parameter setting and start/stop control, ensuring production safety. Medical testing instruments: Portable blood pressure meters, blood glucose meters, and electrocardiogram machines often adopt this solution. The surface of the resistive screen is usually made of flexible material, with a soft touch, and easy to clean and disinfect, meeting the strict requirements of medical equipment. Handheld testing instruments: Such as multimeters, distance meters, environmental detectors, etc., outdoor equipment. The resistive screen remains sensitive in low-temperature environments and is not affected by rain or oil stains, adapting to a wide temperature working range of -20°C to 70°C. Smart home and security: Used in smart door lock panels, video intercoms, and temperature controllers. Its low power consumption helps extend the battery-powered equipment's battery life, while providing intuitive menu navigation.
