Qt Framework
Qt Framework is a popular tool for creating user-friendly screens and controls in cars, medical devices, and other electronic displays. Think of it as a builder's toolkit that helps developers create smooth, modern-looking interfaces - like the touchscreen in your car that controls music and navigation. It works across different types of devices and computers, which makes it very practical for companies making electronics. While some companies might use Android Auto or other systems, Qt is particularly good for creating custom displays that need to work reliably in specialized equipment.
