Product Description
H043IWQ40E3595 is a 4.3 inch TFT LCD Display. This LCD screen uses a TN panel, with a resolution of 480x272, a 16:9 widescreen ratio, a MCU/SPI 40-pin interface, compatible with mainstream MCUs such as STM32 and ESP32, low power consumption and simple driving. It features the NV3041A Driver IC, a brightness of 350 nit, an industrial-grade operating temperature range of -20°C to 70°C, and some models can extend to -30°C to 80°C. It offers both resistive (supporting glove operation) or capacitive (supporting multi-touch) touch screens as options. This 4.3 inch TFT LCD module is mainly used in industrial control terminals: for displaying device status, parameter settings, and alarm information, and is the core component of the human-machine interface (HMI). It is commonly found in access control systems, video intercoms, smart gateways, and home control panels, used for presenting information and providing touch interaction. It is also used for charging display: for real-time display of charging status, parameters, and abnormal alerts. Additionally, it can be applied in: portable medical equipment, self-service terminals, IoT terminals, and other fields.
