Both concepts should explain how the color will be represented on the screen, but when talking about BPC it becomes even more controversial, because they combine three different meanings at the same time.
The interpretation of PCB is very complicated
BPC is known as pieces each part, bits per channel or bits per color when all refer to the color component, that is why they enter the correct depth of each color displayed.
But at the same time, the name shows the difference between depth and half, channel and color. And that the 8 bits are not the same color depth as the 8 BPC, something that is often confusing with the normal size.
Deep beaches within the RGB color space, are grouped up to 2 up to 8, resulting in a range 256 colors are red, 256 are green and 256 are blue.
In BPC, the color space is up to 16 as a general rule, which it gives 65,536 options for each RGB color so it is very clear. So how many colors do each of these games represent? The answer is simple, depending on the minimum depth available in the panel.
For example, in an 8-bit example, we can reproduce 2 ^ 8 x 3 = 2 ^ 24 = 16.7 million colors in which within each pixel you can select 256 shades for each RGB color.
Why are bets being used as an idea over BPC?
The industry is at this stage, and for a very simple reason. If a hacker can't offer a variety of colors that a graphics card can use, why set and focus the industry on PCBs?
We can put a Quadro graphics card on the gaming monitor and no matter how much the BPC does, it will produce the maximum amount allowed by his panel. Therefore, in the professional photography and technology industry, panels are becoming more popular (up to 30 at the moment) and GPUs can work with higher BPC than desktop or game.
Therefore, in the general market it is much more accurate to deal with the first than the second, because moreover and once you have seen the debate in bits, it would be more reliable for manufacturers to talk about BPC.
It is the same situation that happens in RAM with MT / s and MHz, combined but quite different.
