RGB application of led lights
Most monitors use RGB color standards,
On the monitor, colors are generated by hitting the red, green, and blue light-emitting poles of the screen with an electron gun. Computers generally can display 32-bit colors, with more than 10 million colors. [1]
All the colors on the computer screen are composed of the red, green and blue colors mixed in different proportions. A group of red, green and blue is the smallest display unit. Any color on the screen can be recorded and expressed by a set of RGB values.
Therefore, the red, green and blue are also called the three primary colors, which are R (red), G (green), and B (blue) in English.
In computers, the so-called "how much" of RGB refers to brightness, and it is represented by integers. Under normal circumstances, RGB each has 256 levels of brightness, which are represented by numbers from 0, 1, 2... until 255. Note that although the highest number is 255, 0 is also one of the numbers, so there are 256 levels in total. It is like 11 years from 2000 to 2010.
According to calculations, 256-level RGB colors can combine a total of about 16.78 million colors, that is, 256×256×256=16777216. Often referred to as 16 million colors or tens of millions of colors. Also called 24-bit color (2 to the 24th power).
In the LED field, three-in-one dot-array full-color technology is used, that is, full-color pixels are composed of RGB three-color chips in a light-emitting unit. As this technology continues to mature, led display technology will bring people a richer and more true color experience.
