Smartphone screens are the display components of mobile phones that allow users to interact with their devices. They typically use technologies like LCD (Liquid Crystal Display) or OLED (Organic Light Emitting Diode) to produce vibrant colors and sharp images. The size of smartphone screens usually ranges from 5 to 7 inches diagonally, providing a balance between portability and usability. These screens are often touch-sensitive, enabling users to navigate apps, browse the internet, and play games with simple finger gestures. Many modern smartphones also feature protective glass, such as Gorilla Glass, to enhance durability and resist scratches.
