The RGB color mode uses the RGB model to assign intensity values ranging from 0 to 255 to the RGB components of each pixel in the image. For the superposition of red, green and blue three-light areas, the brightest superposition area of the central three colors is white, and the characteristics of additive mixing are: the more superposition, the brighter.

Red, green and blue three color channels, each color is divided into 255 levels of brightness. When the value is 0, the Light is the weakest-off, and when the value is 255, the Light is the brightest. When the values of the three colors are the same, it is colorless gray, while when all three colors are 255, it is the brightest white, and when all three colors are 0, it is black. All the colors on the computer screen are composed of red, green and blue light in different proportions.

Extended data

Application:

At present, most displays use RGB color standard. On the display, the color is produced by striking the red, green and blue light-emitting electrodes of the screen with an electron gun. At present, computers can generally display 32-bit colors, with more than one million colors.

In the led? This field adopts three-in-one dot matrix full-color technology, that is, RGB three-color chipset is synthesized into full-color pixel in a light-emitting unit. With the continuous maturity of this technology, led display technology will bring more rich and true color feelings to people.
