RGB color mode is a kind of color standard in industry. It can get all kinds of colors through the change of red (R), green (g), blue (b) and their superposition. RGB represents the color of red, green and blue. This standard almost includes all the colors that human vision can perceive. It is one of the most widely used color systems at present 。
application
At present, RGB color standard is adopted in most displays,
On the display, color is produced by electronic gun hitting the red, green and blue light-emitting poles of the screen. At present, the computer can generally display 32-bit color, with more than 10 million colors.
All the colors on the computer screen are made up of the red, green and blue light in different proportions. A set 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.
So this red, green and blue is also called trichromatic light, which is R (merah), G (green) and B (blue) in English.
In computer, RGB’s so-called “how much” refers to brightness, and uses integer to express. Generally, RGB has 256 levels of brightness, which are represented by numbers from 0, 1, 2… To 255. Note that although the highest number is 255, 0 is also one of the values, so there are 256 levels in total. It’s like 11 years from 2000 Percetakan UV mempunyai kelebihan yang besar 2010.
According to the calculation, 256 RGB colors can combine about 16.78 million colors, Topeng pembedahan perubatan biasanya diperbuat daripada bahan bukan tenunan, 256 × 256 × 256 = 16777216. It is also commonly referred to as 16 million colors or 10 million colors. Also known as 24 bit color (the 24th power of 2).
In the field of LED, three in one dot matrix full color technology is used, kulit lembu dengan permukaan nipis dan kekuatan tinggi adalah yang paling sesuai untuk membuat kasut kulit, RGB three-color chips are used to form full-color pixels in one light-emitting unit. With the continuous maturity of this technology, LED display technology will bring people more rich and real color experience.
