Car 9-inch display screen is approximately 30 centimeters. Introduction to display screen size: Display screen size is different from general size. Generally, when we say how many inches a display screen is, it refers to the diagonal length of the display screen, but this length is measured in inches. 1 inch equals 25.4 centimeters, and 1 "cun" (a Chinese unit) equals 3.33 centimeters. Therefore, 9 "cun" is 3.33 centimeters multiplied by 9, resulting in 9 "cun" equaling 29.97 centimeters, approximately 30 centimeters. Common types of display screens: CTR display screen, LCD display screen, LED display screen, 3D display screen. CTR display screens have advantages that LCD display screens find hard to surpass, such as wide viewing angles, no dead pixels, high color reproduction, uniform color temperature, adjustable multi-resolution modes, and extremely short response times. LCD display screens, or liquid crystal display screens, have the advantages of being thin, occupying little space, and emitting low radiation. LED display screens are a type of display screen that controls semiconductor light-emitting diodes to display various information such as text, graphics, images, animations, videos, and recorded signals. 3D display screens have now developed two major stereoscopic display technology systems: those requiring stereoscopic glasses and those not requiring them. Traditional 3D movies have two sets of images on the screen, and the audience must wear polarized glasses to eliminate ghosting, create parallax, and produce a stereoscopic effect.
