I. Definition
The screen is a rectangular electronic device surface for displaying images and characters. It can be a display on computers, mobile phones, televisions, projectors and other devices, or it can be a separate display device, such as a display screen and a touch screen.
Two. development history
Screen technology has experienced many years of development, from the early CRT (cathode ray tube) display to the later LCD (liquid crystal display) and LED (light emitting diode) display, and then to the more popular display technologies such as organic light emitting diode (OLED) and AMOLED (active matrix organic light emitting diode).
At the same time, the resolution of the screen is constantly improving, from the initial 480p and 720p, it has now developed to the resolution level of 4K, 8K or even higher.
Three. application area
Screen is widely used in various fields, for example, in the medical industry, doctors can display the diagnosis results of patients through the screen; In the education industry, teachers can present the course content on the screen; In the advertising industry, the screen has become one of the important media; In the game industry, high-definition display and VR technology enable gamers to experience game scenes more realistically.
Four. Technical development trend
1. Intelligentization: The screen is not only a traditional display, but also a control panel in smart homes, smart vehicles and other fields.
2. Curved surface display: The new organic light-emitting diode technology can realize a more flexible screen, which makes curved surface display (for curved TV or mobile devices) possible.
3.VR and AR technologies: Virtual reality and augmented reality technologies need higher resolution and more flexible display devices, and the development of screens will completely expand the unlimited imagination of the industry.
In a word, as the core component of modern electronic products, screen technology is constantly developing and optimizing, which brings people a more exciting digital life. With the continuous progress of science and technology, we look forward to the more extensive and far-reaching expansion of screen display technology in the future.
