What technical aspect does the term "pixel pitch" refer to in displays?

Pixel pitch specifically refers to the distance between the center of one pixel to the center of an adjacent pixel on a display. This measurement is crucial because it directly affects the clarity and detail of the image displayed; a smaller pixel pitch means that the pixels are closer together, which generally allows for higher resolution images and less noticeable pixelation. This feature is particularly important in applications where viewers are close to the screen, as it enhances visual quality.

In contrast, while the resolution of an image does relate to pixel density (the number of pixels in a given area), pixel pitch is a more precise term that focuses solely on the spacing between individual pixels rather than the overall count or arrangement. The size of the screen and the refresh rate of a display, while important characteristics, do not define pixel pitch in any way. Understanding pixel pitch allows technicians and designers to select appropriate displays for different environments and viewing conditions, ensuring optimal visual performance.
