Since the invention of the first mobile phone in the world in 1973, the development process of mobile screen has gone through many years of changes and innovation. Initially, mobile phone screens typically used LCD screens, although the brightness of these screens was low, the degree was narrow, and the color adjustment scene appeared pale, but it changed the way communication was done. In 2007, Apple launched its first smartphone iPhone, marking the arrival of the smartphone era. With innovative multi touch screen technology, it completely redefined the mobile screen. Afterwards, significant progress has been made in display technology, including rapid development and improvement in technologies such as AMOLED, IPS, and TFT-LCD. Screen pixels and brightness have been significantly improved, while the color representation ability, contrast, and response time of OLED screens have also been significantly improved. Full screen and curved screen, as a new type of display technology, solve the difficulties and bottlenecks in the previous use of mobile phone screens; Folding screen technology has also sparked a new trend in the development of mobile screens. The development of mobile screens worldwide has undergone various transformations, upgrades, and innovations, meeting people's needs for high-quality, high-definition visual displays.
