4.3 inch 480×272 TN TFT LCD display with resistive touch panel
Product detail
Product Description
H043IWQ40E3549-T is a 4.3-inch TFT LCD module with resistive touch function. This LCD screen adopts TN panel, with a resolution of 480×272, 24-bit RGB 40-pin interface, and ST7282 Driver IC. It has a brightness of 300 nits and can withstand operating temperatures ranging from -20℃ to +70℃. The 4.3-inch resistive touch screen is widely used in many fields due to its durability, strong anti-interference ability and support for multiple touch control methods . Industrial control and Automation: In the field of industrial automation, 4.3-inch resistive touch screens are often used as human-machine interfaces to connect PLC controllers, instrument panels, data loggers, and weighing and force measurement equipment, etc. It can display the operating parameters of the equipment in real time and allow the operator to directly set parameters, query historical data or handle alarm information by touch. Medical equipment: In medical equipment, the intuitiveness and convenience of the 4.3-inch resistive touch screen can help doctors quickly control the equipment . In addition, it is also applied in fields such as instrumentation, smart home, and transportation.
