When you look at the screen parameters of mobile phones, you often see the terms VGA, QVGA, WQVGA, HVGA, 720P, etc. What exactly do they mean, and how will they affect mobile phones? Now we have sorted out some information about the screen resolution. Let's understand it together.

In fact, our screen is composed of dots one by one, and each dot is a pixel. And these points are very small, like the screen of the monitor, we must be close to see clearly, while the pixel points on the mobile phone are smaller, like the iPhone retina screen, Apple's official even said that this is beyond the range of human eyes can recognize (in fact, I can see clearly when I look carefully!)

If the screen has 1024 horizontal pixels and 768 vertical pixels, the phone resolution is 1024X768. If it has 1280 horizontal pixels and 720 vertical pixels, the phone resolution is 1280X720. This is the definition of screen resolution. If you also want to know the resolution of your screen, you can try to count it with a magnifying glass, but I believe it will collapse.

What we usually say about VGA, QVGA, WQVGA, HVGA, 720P is actually the resolution of the screen.

The full name of VGA is Video Graphics Array, which refers to the resolution of 640 * 480.

QVGA means Quarter VGA, which means one quarter of the resolution of VGA. HTC Wildfire, for example, uses this resolution.

WQVGA is a widescreen version of QVGA, which means that QVGA provides more horizontal pixels when it is the same height as 240 pixels. Sony Ericsson Aino also belongs to this category.

HVGA means Half size VGA. The resolution is only half of VGA, 480 * 320. The typical model is iPhone 3GS.

QHD means Quarter High Definition, which is a quarter of FHD1920X1080, or 960 * 540 resolution,

The 720P screen refers to the 1280 * 720 resolution screen. At present, many mobile phones with higher configurations use this resolution, such as Xiaomi 2, Samsung Galaxy Note 2, and Galaxy S 3.

The 1080P screen refers to the 1920 * 1080 resolution screen. At present, there are not many mobile phones using this resolution. Recently, OPPO Find 5, HTC Butterfly and the upcoming Nubia Z5 all use this resolution.

Does that mean that the higher the resolution of the screen, the better? In theory, in the same area, the higher the screen resolution, the finer the screen image. However, as the screen resolution becomes higher, the corresponding requirements for mobile phone chips will also become higher, so we can see that in the previous run, the Xiaomi 2 with Qualcomm APQ 8064 chip is higher than the HTC butterfly with 1080p resolution, and we can hardly see any difference in the screen resolution within a certain size. In addition, the increase of screen resolution will also increase the power consumption of the screen.
