4.3 inch 480×272 IPS TFT LCD display with capacitive touch panel
Product detail
Product Description
H043BWQ40I3589-CT1 is a 4.3-inch TFT LCD module with capacitive touch function. This LCD screen adopts an IPS panel with a resolution of 480×272, full viewing Angle, 24-bit RGB 40-pin interface ST7283-G4-1-E Driver IC, with a brightness of 250 nits, can withstand operating temperatures ranging from -20℃ to +70℃. This 4.3-inch TFT LCD screen is mainly applied in industrial control equipment : such as control panels of automated production lines, weighing and force measurement instruments, industrial PDAs, etc. It is used for real-time parameter display, fault alarm and operation setting. It supports wide temperature range operation (such as -20℃ to 70℃) and anti-interference ability, and is suitable for complex environments. Consumer electronics : including smart speakers, handheld terminals (such as logistics barcode scanners), smart home central control screens, etc., provide intuitive interactive interfaces, support multi-touch, and enhance user experience. Smart home and self-service devices : such as smart door locks, vending machines, facial recognition terminals, etc., as the core of human-computer interaction, support multi-device linkage and scene mode switching. In addition, it is also applied in fields such as in-vehicle displays, medical equipment, and instruments.
