What is the difference between a screen and a screen?

Screen: also known as display screen, refers to all display devices used to display images and colors. It covers mobile phone screen, computer screen, movie screen, TV screen, LED screen, projection screen and so on in daily life.

Screen: also known as curtain, it refers to the screen that shows the projection when the film is shown, and sometimes it also refers to the reverse projection of the film. The screen itself does not emit light, and the image projected on it is restored according to the reflection principle, and its performance is reflected in the reflection coefficient and color reproduction rate.

Screen: Also known as screen, it generally refers to the screen of a television receiver, and generally refers to various display panels used for electronic luminescence imaging (initially refers to display panels that use cathode ray tubes (CRT) to emit light, such as early televisions and monitors). The word "fluorescence" also comes from the phosphor coated on the display panel of CRT system. Now these display devices don't use phosphor. )。
