The resolution calculation formula of LED display is: resolution = (screen length mm / dot pitch mm) * (screen height mm / dot pitch mm). In this formula, screen length and height refer to the actual physical size of the LED display, usually in millimeters; dot pitch refers to the distance from the center of one lamp bead to the center of the adjacent lamp bead, also in millimeters.
Relationship between resolution and dot pitch
The smaller the dot pitch, the higher the resolution and the higher the clarity of the screen. For example, the dot pitch of P2 is 2mm, while the dot pitch of P0.9 is only 0.9mm, so the resolution of P0.9 will be higher than that of P2.
Actual calculation example
Suppose there is an LED display with a length of 4 meters, a height of 2 meters, and a dot pitch of 2mm, then its resolution is calculated as follows:
Screen length: 4000mm / 2mm = 2000 pixels
Screen height: 2000mm / 2mm = 1000 pixels
Therefore, the resolution of this LED display is 2000 pixels * 1000 pixels.
Through this formula and example, we can clearly understand how to calculate the resolution of the LED display and choose the appropriate dot pitch as needed to achieve the ideal clarity and resolution.
