Custom 2.8 inch 240×320 TN TFT LCD Module with resistive touch panel Manufacturers, Supplier
Product Description
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.
Industrial Control & HMI
Ideal for PLC control panels, frequency converter operators, and automation equipment. Resists electromagnetic interference and allows operation with thick protective gloves.
Medical Testing Instruments
Used in portable blood pressure meters, glucose meters, and ECG machines. The flexible resistive screen is smooth, durable, and easy to sanitize thoroughly.
Handheld Testing Devices
Multimeters, distance meters, and detectors operate smoothly outdoors. Functions reliably from -20°C to 70°C, impervious to rain, grease, and dust.
Smart Home & Security
Applied in smart door lock panels, video intercoms, and thermostats. Ultra-low power consumption extends equipment battery longevity effectively.
