4 Inch 480×480 RGB IPS TFT LCD Module with Capacitive Touch - China Suppliers & Factory Direct Offer
H040HWQ40I3509-CT1 is a 4-inch TFT LCD module. This is a square-display TFT LCD module with a resolution of 480×480 pixels. It features IPS full-view technology, capacitive multi-touch technology, and uses the GC9503CV driving chip. It supports RGB or MIPI interface methods. It has anti-interference design, supports wide temperature operation, and some models integrate tempered glass covers to enhance durability. The 1:1 square ratio is more suitable for UI icon layout, especially for smart panels, HMI human-machine interface design, and improving interaction experience.
This product is widely used in smart home, industrial control, medical equipment, and IoT terminals. For example, it is used in smart panels installed in 86 boxes to achieve one-click control of lights, air conditioners, and curtains. As an industrial human-machine interface (HMI), it is used for PLC control, equipment monitoring, and data acquisition systems. It is used in portable medical instruments, such as blood pressure monitors and monitors, requiring high reliability and clear display, and supporting low-temperature environment startup.
