In the past year, although many mobile phone manufacturers have begun to work hard on the screen to supplement various parameters. However, in addition to the well-known resolution and refresh rate, color depth has been ignored as a slightly unpopular parameter.
The recently released Honor V40 mobile phone, in addition to high resolution and high brush, regards 10bit color depth as an extremely important selling point. So what exactly does 10bit mean? How does it improve our daily mobile phone use? I believe that after reading this article today, everyone will have a certain preliminary understanding.
Before introducing the enhancement of 10bit color depth, first of all, we need to understand what is meant by 10bit color depth.
As we all know, the colors displayed by most electronic devices around us are based on the combination of RGB three primary colors. As for the 8-bit color-deep screen devices we often say, their R, G, and B three color channels have the ability to display 28 or 256-bit color scales respectively, so this type of device can display 2563 colors, or 1677. Thousands of colors.

Therefore, as the name suggests, the 10-bit color depth is increased by up to 4 times on a single color channel compared to 8bit. The single-channel has been upgraded from a 256-bit color scale to as high as a 1024-bit color scale. You can imagine that without looking at the actual picture, the color transition will inevitably be more delicate. Counting the three channels together, the total number of colors has jumped from 16.67 million colors to 1.07 billion, and the displayed image is closer to the natural look and feel.
There are obvious differences in pure color transitions under different color depths. Jitter can reduce the impact of differences.
If there is no comparison, in most scenarios in life, it is difficult for us to intuitively feel the difference between 8bit and 10bit. But once you get used to 10bit and suddenly see the content displayed in 8bit, you can feel the obvious difference.
The most obvious difference in image color depth is the pure color change. In the display test, we often use the gradient of grayscale to measure the color depth of the display. 10bit content will be adaptively displayed as delicate changes, while lower 8bit content or even 6bit content will show obvious color band distribution.
When shooting, the color depth is not handled properly or the device color depth is too low, and the blue sky will be broken.
Put the usage scene in the mobile phone, and the improvement it brings is naturally the perfect support for the more delicate 10bit material. Like many photographers, they will choose a color depth of 10bit or even 12bit to shoot the original material when taking pictures and videos. To leave ample space for creation in the later stage, a 10-bit color-deep display device is essential for viewing these materials correctly. Like mobile phones, as one of the most convenient and commonly used electronic devices around, the support of a 10bit color depth display is very important for this creative work.
On the other hand, in addition to taking pictures and photography, the most important thing for ordinary people in 10bit is the improvement of color when watching movies and movies. Although the current domestic streaming media has not yet popularized 10bit, for users who love to download and watch dramas, in recent years, many foreign film and television works can easily find 4K HDR 10bit or even higher specification resources. Using this 10-bit screen of the Honor V40, you can get a more delicate picture display. Like the lightsaber in the picture, the surrounding halo can be spread out very naturally, without obvious light bands.
In addition, under the same specifications, 10bit video resources are actually more advantageous in file size and bit rate than 8bit resources. This is because 10bit has a more accurate color display, no need to worry about color blocks, let alone use dithering and other technologies to eliminate them and bring a lot of redundant information. Therefore, 10bit re-encoding can achieve high image quality with a lower bit rate and a higher compression rate, which is also a great boon for collection. To realize its value, hardware devices that support a 10bit display are naturally indispensable.
I believe that after reading these, everyone can have a general understanding of the importance and improvement of 10bit. If you want to enjoy the ultimate picture quality of 10bit HDR on your mobile phone, a hardware device that supports 10bit display is essential. But at present, there are not many mobile phones that support 10bit display on the market, and the newly released Honor V40 happens to be among them, and in terms of price, it is also the most economical choice among them. You might as well buy one and experience the delicate colors brought by 10bit.
