16:9 size conversion led large screen

#16:9 screen is simply made for watching videos. At present, most high-definition videos and movies on the Internet adopt this ratio, and they can be displayed in full screen when watching without worrying about black borders.                                                                                                                                                                                                                                     (Recommended learning: phpstorm)

When playing games, a screen of this ratio can also give players a more reasonable viewing area. It can be said to be a more balanced ratio.

What is screen ratio?

We generally call the ratio of screen width and height as aspect ratio (Aspect Ratio, also called aspect ratio or screen ratio). Different screen-to-body ratios bring different effects to users. Currently, the screen ratios of tablet computers are basically three ratios: 4:3, 16:9, and 16:10, and their display effects also have certain differences.

The width is the square root of the square number multiplied by 16 and divided by 12

The height is the square root of the square number multiplied by 9 and divided by 12

LED display (LED display) is a flat-panel display, which is composed of small LED module panels and is used to display various information such as text, images, videos, and video signals. LED, light emitting diode (abbreviation of light emitting diode).

It is a display method that controls semiconductor light-emitting diodes. It is a diode made of compounds of gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and indium (In). , when electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes.

Used as indicator lights in circuits and instruments, or formed into text or digital displays. The gallium arsenide phosphorus diode emits red light, the gallium phosphide diode emits green light, the silicon carbide diode emits yellow light, and the indium gallium nitrogen diode emits blue light

If the display screen is 16 meters long and 9 meters high, It’s a 16:9 ratio; the display is 10 meters long and 5.6 meters high, also in a 16:9 ratio.
