What is the Common Display Resolution?

The display resolution is one of the key factors to consider in project development in light of visual quality features. There are common display resolutions used in industrial and commercial instruments.

Display Resolution

Display resolution refers to the number of pixels a display can show horizontally and vertically. It is typically measured in terms of the number of pixels along the horizontal axis by the number of pixels along the vertical axis, such as “1920×1080” or “1080p”.

The resolution of a display is one of the important factors to consider in project development in light of visual quality features. 

Pixel Pitch

LCD screens with the same resolution will have various sizes, in other words, the pixel pitches of the LCD screens will be different.

The pixel pitch refers to the distance between two adjacent pixel points on the display screen (that is, the center distance between adjacent dots of the same primary color). 

Under the premise of a certain display screen size, the smaller the dot pitch, the tighter the arrangement of pixels on the screen, and the clearer and more delicate the image.

Divide the width and height of the display area by the dot pitch to get the maximum number of dots that the display can display in the vertical and horizontal directions, the result is the resolution. 

At present, the dot pitch mainly has several specifications such as 0.39, 0.31, 0.28, 0.26, 0.24, 0.22mm, etc., and the smallest can reach 0.20mm.


Besides, we use the terms PPI (pixels per inch) and DPI (dots per inch) to express the pixel density.

Development of the display resolution

The development of display resolution has gone through several stages over the years.

In the stage of CRT display, most displays had a resolution of 640×480 pixels or less.

However, as technology advanced to the flat panel display, higher resolutions became possible. The 800×600 resolution was introduced, followed by the 1024×768 resolution, which became a standard for many years.

In the late 1990s and early 2000s, the 1280×1024 resolution became popular for desktop displays. This was followed by the introduction of widescreen displays with resolutions such as 1680×1050 and 1920×1200.

In recent years, 4K (3840×2160) and even 8K (7680×4320) resolutions have become available, offering incredibly sharp and detailed images. There are also ultra-wide monitors with resolutions of 3440×1440 or higher, providing a wider aspect ratio for an immersive viewing experience.

As technology continues to improve, we can expect even higher resolutions and more advanced display technologies to become available.

Common display resolution

The common resolution of the small-and-medium size LCD modules used in industrial instruments and commercial terminals:

You will also notice there are names representing the specific resolutions. The origin of the naming is often traced back to the manufacturers who developed the display technology and the applications at that time.

Following families are the key resolutions in the market:

# HD (High-Definition)

# VGA (Video Graphics Array)

# XGA (Extended Graphics Array)

Note that these are just some of the common display resolutions, and there are many others that are less common or specialized for specific applications.

Eventually, the resolution is only one of the display features. The development and adoption are subject to the market application and together with other display technologies to present the optimal integrated display effect.
