4.3 Inch COF Industrial Smart TFT HMI Display with Capacitive Touch and DGUS II System

The DMG48270F043_01WTC is a compact 4.3-inch industrial smart HMI display from DWIN Technology, engineered around the T5L0 dual-core ASIC and powered by the DGUS II system. It integrates display, touch, processing, and control logic directly into the LCD module using a COF (Chip-on-Flex) structure, making it ideal for applications that demand a thin profile, lightweight construction, and simplified system design.

Featuring a 480×272 resolution TN-TFT panel with 262K colours and a responsive capacitive touch screen, this smart display delivers stable visual performance for embedded and industrial interfaces. The 50-pin 0.5 mm FPC connector exposes rich peripheral resources including GPIO, UART, CAN, ADC, and PWM, enabling easy secondary development without an external MCU. Operating from a 3.6–5.5 V supply with low power consumption, the DMG48270F043_01WTC is well suited for control panels, portable instruments, and cost-sensitive HMI designs.
