LED screen resolution and dot spacing are two important indicators for evaluating the display quality of LED screens. Understanding the meaning and relationship between its resolution and point spacing is crucial to obtain the ideal display effect.

1. the concept of LED screen resolution and point spacing

Resolution
Resolution refers to the precision of the screen image, that is, the number of pixels that the display can display. The higher the resolution, the sharper the image and the better the detail.
For LED displays, the resolution is usually expressed by the number of horizontal pixels × the number of vertical pixels. For example, an LED display has a resolution of 1920×1080, which means that it has 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction.

Dot spacing
Point pitch refers to the center distance between two adjacent pixel points on the LED display, usually expressed in millimeters (mm).
The smaller the point spacing, the more pixels per unit area, the higher the resolution of the display, the clearer the image. Conversely, the greater the point spacing, the lower the resolution and the coarser the image.



2. LED screen resolution is generally how much
The resolution of the LED screen varies depending on the screen size, dot spacing, and application scenarios. Here are some common LED screen resolutions:

Indoor small pitch LED screen:
The point spacing is usually between 1mm and 2.5mm.
Common resolutions are 1920×1080, 2560×1440, 3840×2160, etc., which can meet the needs of high-definition video playback and conference display.

Indoor medium pitch LED screen:
The point spacing is generally between 2.5mm and 4mm.
The resolution may be 1280×720, 1440×900, etc., which is suitable for shopping mall advertising, indoor display and other occasions.

Outdoor LED screen:
The point spacing is relatively large, usually more than 4mm.
The common resolution is 960×480, 1024×768, etc., because the viewing distance is far, the resolution requirements are relatively low, but the need for higher brightness and protection performance.

3. the factors that affect the resolution of the LED screen

Point spacing: Point spacing is one of the key factors in determining resolution. The smaller the point spacing, the higher the resolution.

Screen size: In the case of the same point spacing, the larger the screen size, the lower the resolution. For example, an LED display with a point spacing of 3mm will have a different resolution on an area of 10 square meters and an area of 50 square meters.

Viewing distance: Viewing distance also affects the resolution requirements. If the viewing distance is far, even if the resolution is low, it may not significantly affect the viewing effect. On the contrary, if the viewing distance is close, a higher resolution is required to ensure the clarity of the image.

4. how to choose the right LED screen resolution

Select based on the application scenario:
If it is used for indoor high-definition video playback, conference display and other occasions, the small-pitch LED screen should be selected to obtain high-resolution image effects.
For shopping mall advertising, indoor display and other occasions, medium-pitch LED screens may be enough to meet the needs.
Outdoor LED screen due to the viewing distance is far, the resolution requirements are relatively low, but need to consider brightness, protection performance and other factors.

Consider viewing distance:
When the viewing distance is close, a high-resolution LED screen should be selected to ensure the clarity of the image.
When the viewing distance is far, the requirement for resolution can be appropriately reduced to save costs.

Combined with budgetary considerations:
Small pitch LED screen resolution is high, but the price is relatively high. When choosing, you need to balance the relationship between resolution and cost based on budget.
