1. LED Screen Pixel Pitch

The distance between the LED screen diodes determines the resolution of the screen. From the center of each set of red, green, and blue diodes, the distance to the center of the adjacent group is measured. This distance is called the pixel pitch. Each set of diodes together form a pixel – or pixel.

If the LED screen has a pixel pitch of 1 cm, each pixel can have 100 x 100 pixels. Square screen. The resolution on the screen is set to the number of pixels in height and width. If your screen is 6 x 8 meters and the pixel spacing is 1 cm, the resolution is 600 x 800 pixels.

2. Image Resolution

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.

Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. For example, an image that is 2048 pixels wide and 1536 pixels high (2048 x 1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels).

Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes , to the overall size of a picture, or to angular subtense.

The measure of how closely lines can be resolved in an image is called spatial resolution, and it depends on properties of the system creating the image, not just the pixel resolution in pixels per inch (ppi). In effect, spatial resolution refers to the number of independent pixel values per unit length. Get more details of small pixel pitch led screen from www.chipshow.com.
