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.
Used in PLC panels and automation equipment; supports thick protective gloves and resists electromagnetic interference.
Ideal for portable blood pressure meters and ECG machines; easy to clean and disinfect for medical environments.
Adapts to multimeters and environmental detectors; remains sensitive in low temperatures (-20°C to 70°C).
Applicable for smart door locks and video intercoms; provides low power consumption for battery-powered life.
