When people operate LED display products, they need to find out the pixel resolution of the screen or each panel. Here we will have the solution for you.
P3.9 LED display
Before we discuss this question, we need to know what is the pixel pitch? Pixel pitch is the measurement of the smallest bit of data in a video image. For LED display, the pixel pitch means the distance between two contiguous LEDs measured in millimeter. The smaller the size of the pixel pitch, the higher density of LEDs, the greater the resolution. So P6 has higher resolution than P10.
P10 means the pixel pitch is 10mm. Likewise, P6 means the pixel pitch is 6mm. So the number after P is the pixel pitch in millimeter. But there are some special pixel pitch using different figures. For example, for the common type P3.9, actually its pixel pitch is 3.906mm. Also for P4.8, its pixel pitch is 4.807mm.
Now we explain how to calculate how many pixels on each cabinet. Let's take an example of P10 with the cabinet size of 1280mm x 960mm. First, we calculate the width's resolution. We could have the width of the panel measured in millimeter, then that number will be divided by the pixel pitch also measured in millimeter. So the resolution of the width of p10 is 1280/10 which is 128 pixels. Likewise, we could use the same way to have the resolution of its height. So the resolution of the height is 960/10 which is 96 pixels.
And how to calculate how many pixels on the screen? There are two ways.
First, we could use the same way like above mentioned. We measured the dimension of the screen in millimeter, and then we could have the numbers of the width and the height. So these numbers will be divided by the pixel pitch also measured in millimeter. So we could have the resolution for the whole screen. For example, if there is a P10 screen with the size of 3.84m x 2.88m. So we could have the width measured in millimeter 3840mm, and we have the height measured in millimeter 2880mm. And then these numbers would be divided by the pixel pitch 10mm. So the screen's resolution will be 384(W) x 288(H).
Second, we could calculate how many pixels on each cabinet. And then we could find out how many panels on this screen. Then we could know the whole screen's resolution. For example, if a P10 screen has 12 pieces of panels (all of panels have same size), and their array is 4pcs width and 3pcs height. If we know each panel has 96 pixels by 96pxiel. Then we could know the whole screen will be 384 pixels (W) x 288pixels (H).
