We hear PPI a lot while shopping for TV’s mobile etc. but what does that mean?, PPI is an abbreviation of Pixels Per Inch refers to how many individual pixels are displayed in one inch of a digital image. More the Pixel Per Inch, the clearer the display is. Likewise, in LED displays 1 pixel equals 1 Light-Emitting Diode (LED). There are fixed numbers of LEDs in a panel and the number of these LEDs defines the price of the panel. The distance between two LEDs is known as pixel pitch. Lesser the pixel pitch denser the LED presence in a display and hence higher pixel per sq. Feet which make the display more pleasing, with higher contrast ratio and vibrant colors and also increases the product’s price.

Pixel pitch (P) shows the amount of space between two pixels therefore, a smaller pixel pitch means less space between pixels, which makes a better display. The more the Pixel Pitch more Pixelated the display is. For example, P2 boards have a 2 mm distance between two LEDs, and the minimum viewing distance is 2 meters. The minimum viewing distance defines the distance between the viewer and the board. While using P2 boards, the audience can enjoy the best view if the viewer maintains a distance of over 2 meters. So, in P2 boards the density of LED pixels is high therefore the costs get high. The same case is for P4, P6 P8 and P10 LED Display. Hence, the price depends on the viewing distance and size of the board, and pixel pitch. The cost also depends on different components used in the board, for example video processing unit, sensors (Temp, Humidity), etc.
