Defining Pixel Pitch
Undoubtedly, if you have been looking into purchasing an LED Video Display, you have come across the term pixel pitch. Pixel pitch is a key element in determining which LED Video Display is right for you. In order to understand what pixel pitch is, you must first understand what we are defining as a pixel. A pixel is a cluster of colored light sources known as diodes. Each cluster almost always contains at least one red diode, one green diode, and one blue diode. In older LED technology, these clusters could actually be seen as individual lights clustered together, these are DIP (dual in-line pin) diodes. Each cluster makes up one pixel. Pixel pitch measures the distance from the center of one cluster, or pixel, to the center of its neighboring pixel.
With modern surface mounted diode (SMD) technology (pictured below), each SMD pixel (chip) has a tiny red, blue, and green light inside of it. This compact design allows the pixels to be much closer together, greatly increasing the resolution of the display. Pixel pitch is measured in mm. Therefore if an LED Video Display is said to have a pixel pitch of 1.3, the center of each diode is 1.3mm away from the center of its neighboring diode.
Due to advancements in LED technology, HD, UHD, 4K and beyond are possible with modern LED Video Displays. As with other forms of technology, innovation has simultaneously improved the quality of LED Video Displays while driving prices down, making the benefits of LED Video Display more accessible.
