Because the use of pixels and resolution is often confused, some friends think that these two are the same thing, but there is actually a difference. You can tell their differences by reading this article below.
What is pixel?
The minimum luminous unit of a LCD screen is pixels, also known as pixels, and there is also a concept of pixel density. The higher the pixel density, the more pixels there are. Each image is composed of many pixels, and the higher the pixel, the clearer the image. For example, what we often refer to as 2 million pixels, 5 million pixels, and 2 million pixels is equivalent to 2K high-definition.
What is resolution?
Resolution is the number of pixels in each row of the screen multiplied by the number of pixels in each column, and each display screen has its own resolution. The higher the screen resolution, the more colors are presented, and the higher the clarity.
The difference between pixels and resolution
Pixel is a unit of measurement for resolution, and resolution is an important concept related to display screens. Generally speaking, the more pixels there are, the higher the resolution. In terms of 1920 * 1080 resolution, 1920 means there are 1920 pixels horizontally and 1080 pixels vertically, which is 2 million pixels.
The relationship between pixels, resolution, and size
The smaller the size of a display screen with the same pixel, the more pixels per unit area, the higher the resolution, and the clearer the image appears. That's why the larger the size of the same image, the more blurry the image becomes.

A display screen of the same size has higher pixels, more pixels per unit area, higher resolution, and clearer appearance. That's why in the same scene, the image presented at 500W pixels is clearer than the image presented at 200W pixels.
