LED display pixel density and resolution

 - LED display pixel density and resolution

LED displays have become an indispensable part of our daily lives as technology advances. Many people do not understand the difference between pixel density and resolution when purchasing LED displays. We will discuss the meaning of pixel density and resolution of LED displays in this paper.

1.How dense are the pixels?

Pixel density is the number of pixels per unit length or area. Pixels per inch or square inch are the number of pixels on a screen. There are two types of pixels: PPI (Pixel Per Inch) and PPM (Pixel Per Meter).

If a 10-inch LED display has 1000000 pixels, its pixel density is 100 PPI. The higher the pixel density, the better the display quality and clarity.

2.How high is the resolution?

Pixels are arranged on a display screen according to their resolution. In other words, it describes how many pixels can be displayed on a display screen. The most common resolutions are 720P, 1080P, 2K, and 4K.

For example, 720P resolution means 1280 on the screen × 720 pixels, while 1080P resolution means 1920 on the screen × 1080 pixels. In general, the higher the resolution, the finer and clearer the image displayed on the screen will be. A LED display screen with small spacing has a higher resolution than a general display screen.

3.The difference between pixel density and resolution

Both pixel density and resolution are used to describe LED display quality, but they have different meanings.

First, pixel density refers to the number of pixels on the screen, i.e. their size. The resolution refers to the number of pixels arranged on the screen.

Additionally, the higher the pixel density, the more delicate and clear the image displayed on the screen. The higher the resolution, the clearer and more detailed the displayed image, but it also requires a higher pixel density.

As an example, a 10-inch LED display with 1280 x 720 (720P) resolution has a pixel density of 100 pixels per inch. It is necessary to increase the pixel density to at least 150 PPI if you want to increase the resolution to 1920 by 1080 (1080P). Otherwise, the image will be blurry and distorted.

Pixel density and resolution are two different parameters, but they are closely related. The pixel density determines the clarity and detail of an image, while the resolution determines how many pixels can be displayed on the display. In order to select the appropriate LED display screen, you must select the appropriate pixel density and resolution.
